❶�Field construction channel - Place concrete after provid-ing a hole that can accommodate the dimension A. After removing the form, install a valve, fix it with mortar or calking compound and then install a specified pipe.
❷�When using a concrete pit - Place concrete after setting a circular blank form. Follow then the steps same as above.
❸�Flume channel without hole - Bore hole at a required posi-tion. Follow then the steps same as above.
■ Measuring methodMeasuring device is set horizontally on a channel with variable slope. Attaching a valve to the leading end of the device, water is drained to a triangular weir tank.Amount of flow is obtained by measuring the water received in a bucket, when the amount is small (approx. 1 litter/sec), or by measuring the depth of water in the triangular weir in the other.
❹�When installing on earth channel - Jacket the valve with a small amount of concrete, and then install a pipe.
❺�When taking bottom water from flume - Install by providing a concrete pit at the flume joint, and then install the valve.
❻�When heights of water intake position and outlet are different largely - Provide a pit on the irrigation channel, use a bent pipe or finely adjust the angle to install the valve and provide a diversion pit at the outlet.
* Regarding the installation of model AH products, refer to the Installation views ❶ to ❹ for the C-Series manual type sluice gate door (Page 16).

■Construction method for preventing clogged conduitDraining effect of conduits decreases with progress of time owing to clogging.Jet cleansing, or the like, is employed at some places to prevent clogged conduits. These methods, how-ever, are not only expensive but also complicated in handling, maintenance or control. They are not promul-gated so much also because, for example, they may not be applicable depending on conditions of piping.Cleansing method utilizing valves (Model A) has been introduced to solve such problems. The products have been accepted favorably at areas where they are employed.(This method is recommended because of simplified construction work and readiness for use from the very date of construction.)

Installation
Explanation
3-way watertight structure (Fig. 1)◦��When closed fully, water is stopped at watertight sections at three sides of
shutter (bottom, left and right). Water overflows beyond the shutter.◦��Application example
It is installed at the downstream side of intake from channel to dam up water.
* Concrete anchors are not included. Procure at site referring to the dimension R.
4-way watertight structure (Fig. 2)◦��Since, when closed fully, water is stopped at the watertight sections at
four sides of shutter (top, bottom, left and right), water level may be raised beyond the height of shutter. (Round type model has a 4-way watertight structure because it is watertight over entire circumference.)
◦��Application example It is installed at the entrance of conduit for diversion pit to divert water.
■ Anchor bolt construction (Standard)To install on a concrete wall, drill a little larger holes aligning to the positions of a pair of flash bolts (M6 or M10) provided on the left and right frames of main unit.Pack the drilled holes with mortar, and fix the product by means of strut, etc.After fixing the position of product, fill up the clearance between the concrete wall and the product with motor or calking compound. (Fig. 3)
■ Concrete anchor constructionWhen installing the product with concrete anchors, after drilling anchor holes, make sure to fill rubber type joint filler in the clearance between the product and concrete wall before tightening nuts (Fig. 4).
■ Block-out constructionSet the product in the block-out position and pack mortar or sealing agent.

❶�Standard sizes for drainage pipe per unit block area are considered to be 100 for 1,000 square meters, 125 per 2,000 square meters and 150 per 3,000 square meters, though it could vary depending on the amount of rainfall, draining time, depth of impound water, or other, at particular area. It is considered also to install the product at two or more places in unit block area.
❷�Since the L shape external cylinder is installed at approx. 100°and an O ring is attached to the joint to drain pipe, it can be installed arbitrarily under ordinary conditions. Where it is installed at a very steep slope, use the drain pipe after cutting obliquely. (Model E)
❸�Install the drainage pipe with its top end at approx. 30 mm below the average height of the surface of paddy field.
❹�When burying the drainage pipe, tread down the ground sufficiently after it is buried.
❺�Since this drainage pipe is buried at the end toe of slope in principle, use a semi circular concrete pipe, short U shape flume, building block, sand bag, etc., as logging for the slope.
❻�When installing the internal cylinder, set it with the triangle mark indicated on the flange oriented to the surface of paddy field. Lock further the internal cylinder with the at-tached O ring. (Model E)
❼�Since the drain hole for winter time is utilized as a draining hole after draining rice farming water or during secondary crop farming, it is opened if it is inserted with the triangle mark oriented to the drainage channel. Cut open the front of the opening to secure a complete draining. (Model E)
Installation
* X (Standard dimension: 400 mm)
FeaturesModel E: HAISUITOU (E-type)◦��Depth of water in paddy field can be adjusted
by elevating the internal cylinder. (Up to 120 mm)◦��After draining water or for draining at winter
time (or secondary crop period), rain water can be drained through the winter draining hole on the external cylinder to dry the paddy field.
Model EA: HAISUITOU (EA-type)◦��Along with the promotion of agricultural
lands to general purpose fields, the posi-tion to install drainage pipes for draining at winter time is becoming so deep that it has become impossible to drain water by standard draining pipes. For such occasions, special drainage pipes of which the draining position in winter time is brought down are provided.
◦��Vinyl chloride tee located at the bottom end of external cylinder allows providing the drain-age hole for winter time at arbitrary positions.

WEEP HOLE is used to reduce uplift pressure in rivers, reservoirs and water channels.Generally, removal of seepage water or subsurface water around concrete channel would be required, otherwise channel would be floated by the water uplift pressure causing cracks to the structure.WEEP HOLE effectively discharges seepage water or subsurface water without underground soil into the channel, on the other hand, when the channel water level rises, rubber valve of WEEP HOLE closes by cause of water pres-sure preventing channel water from seeping in underground.There are various types of WEEP HOLE (G, GD, GI, GS, GP, GH and GT) depending on the condition being ap-plied at the side wall or bottom of the water channel.

If subsurface water level is high, concrete water channels and reservoirs may be floated by the water uplift pressure of the subsurface water, causing cracks or float to the concrete portion. This is where the underdrain construction method or the sidedrain construction method is employed, and WEEP HOLE is used to prevent backflow at the drain outlet. WEEP HOLE is available in two types: GD and GDL.

WEEP HOLE with Screen reduces the uplift pressure of subsurface water in water channels and balancing reservoirs. WEEP HOLE with Screen can efficiently discharge seepage water and spring water to prevent the float of the sheets of concrete water channels and balancing reservoirs. If the internal water level rises, the rubber valve closes under water pressure to prevent seep-ing into subsurface. WEEP HOLE with Screen can also effectively prevent the back side from being scoured.

Seepage control sheets (soft PVC, rubber) are frequently used for river banks, storage reservoirs and balancing res-ervoirs. However, a problem is how to eliminate uplift pressure due to subsurface water, spring water or remaining air. To solve this problem, we have newly developed WEEP HOLE for Sheet.WEEP HOLE for Sheet is composed of a stainless steel cover, a presser ring, a rubber valve and a screw type main body (synthetic resin). Since the structure is so simple, WEEP HOLE for Sheet is robust free from trouble. Also, WEEP HOLE for Sheet is so small and light, it can be mounted directly on sheets. When WEEP HOLE for Sheet is used together with a drain pipe or an air vent valve, safety can be furthered. For the amount of “weight” for prevent-ing the float of sheets, refer to the calculation formula described later. Thus, WEEP HOLE for Sheet ensures the safety of bank bodies, and substantially reduces the construction labor and cost.
◦No trouble in the valve due to its simply structure. ◦Can be mounted on seepage control sheets of up to 10mm thick.◦ Unnoticeable contour after mounting on seepage control
sheets in storage reservoirs due to the thinness.◦ Easy mounting on seepage control sheets without using nay
special mechanical tools.◦Durable semi-permanently due to synthetic rubber and stainless steel.

Recently, the sheet pile construction method has been increasingly utilized for water channel revetment, etc. in the soft ground area. However, WEEP HOLEs and drain pipes used for this method have not yet been popularly used, and the back pressure is left unmitigated. When water treatment is provided to this backland, the back pressure can be mitigated, and the ground can be stabilized. In order to prevent disaster due to the moistening phenomena at the backland, we have developed WEEP HOLE for Sheet Piling.
◦Easy mounting from the front side of sheet piles.◦Stabilizing structural objects and preventing disasters.◦Easy construction, saving machine use.◦Requiring an extremely small drilled area for construction.
◦ The steel plate contained in the rubber valve prevents the valve body from being warped and maintains the waterproof effect.
◦Easy replacement and repair of the valve.
◦Drill a hole to the approximately φJ in the sheet pile.◦Refine the drilled portion on the water channel side.◦ Apply bond or caulking agent to the joint surface between the
sheet pile and the main body plate, orient the mark on the hook bolt head to the outside, and fasten the butterfly nuts for fixing.

SHISUI-HEKI (Slope protection on pipe)Model S1: SHISUI-HEKI (Slope protection on pipe)
Plastic product
When water is drained through PVC or polyethylene pipe from DRAIN BOX (stop-log), water could leak from around the pipe where it crosses the channel ridge (water path), collapsing the face of slope. To prevent such collapse, a SHISUI-HEKI is installed at the middle of PVC pipe (polyethylene pipe). This construction method allows installing a SHISUI-HEKI (Slope protection on pipe) on newly installed or existing pipe, without cutting the pipe.
Installation view
◦��Light, highly resistant to corrosion and easy for mainte-nance and control.
◦��Installation is simplified because it can be connected to a pipe quite easily.

Model YA: PROTECTION SHEET
PROTECTION SHEETSynthetic rubber product
PROTECTION SHEET is a temporary protective sheet to protect the surface of iron cover of manhole or hand-hole from soiling or adhesion of paving materials (asphalt, etc) during road construction work.
◦ Protection sheet protects the surface of iron cover during repairs or overlay work on the pavement associated with the installation of man-hole or hand-hole.
◦ It can be used both on road way and pavement.◦ It is a thin and special sealing material which fits well in the relief on the surface of iron cover, with some slip-proof effect. (Slip-proof
effect is limited. It may be necessary to take safety measures depending on the conditions at site.)◦ It is a product of seal specification, which can be used easily. Adhesive will not left over on the surface of iron cover after it is removed.◦��It can withstand the heat at asphalt pavement work. Approximate withstanding temperature is 150°C. Paving material should be removed
immediately after finishing the paving. (If it is heated for a long period of time, the adhesive material may be transferred. Care should be taken particularly in case of colored cover.)
◦��Letters, measuring point, etc. can be written on the surface.◦��Service life is approx. 3 months. (It varies widely depending on the conditions of traffic, climate, etc. Please contact us particularly for appli-
cations at trunk road or in cold region.)
◦��Clean the surface of iron cover. Removing the release paper, attach the Protection sheet to the iron cover.
◦��Lightly tap with a plastic hammer, or the like, from above to adhere it firmly. (Attach it always under ordinary temperature. Otherwise, it may not attach firmly.)
◦ After attaching to the Protection sheet, apply light oil over the iron cover protective sheet, to facilitate removal of paving material.
◦Always store it at a cool place, avoiding exposure to direct sunlight.
