摘要:
A self-reset valve has a fixed unit, a water diversion body, a stop mechanism, a drive shaft and a clutch. The fixed unit is disposed with an inlet waterway and at least two waterways. The water diversion body is rotatably connected to the fixed unit inside. The water diversion body is disposed with an outer revolution surface having an outer ratch and an inner revolution surface. The stop mechanism is connected to the fixed unit and acted on the outer ratch. The drive shaft is rotatably connected to the fixed unit. The drive shaft is disposed with a control end and a drive end. The clutch is connected between the drive end of the drive shaft and the inner revolution surface of the water diversion body. The reset elastic body is connected between the drive shaft and the fixed unit.

The present invention is provides with a rocker switch waterway mechanism, which includes an inlet unit, at least two outlet units and a switch mechanism. The switch mechanism includes a rocker and switch valve pin jointed together, the switch valve is disposed inside the cavity of the connection of the two outlet units, and the rocker drives the switch valve moves between the inlets of the two outlet unit to realize the switch of the two outlet units. The present invention is provided with not much switch force, and the switch is convenient.

A pulling-wire waterway switching mechanism has a fixed unit, a water division body, a ratchet shaft, a stopping claw, a returning body and a pulling wire. The water division body can be rotationally arranged in the fixed unit, and can use the rotation between the water division body and the fixed unit to achieve the switch of the outlet functions, a plurality of lower ratchets in anuular array are arranged on the top surface of the water division body, and a plurality of stopping teeth in anuular array are arranged on the outer rotative surface of the water division body. The ratchet shaft provided with a pulling block extending out of the fixed unit and a plurality of upper ratchets in annular array. The pulling block drives the ratchet shaft to rotate forward. The upper ratchets can drive the water division to rotate forward.

A directional fracture grouting method with polymer for seepage control of dikes and dams includes the steps of: arranging a plurality of directional fracture grouting holes at a predetermined distance along the axis of the dike or dam; forming the directional fracture grouting holes by pushing a special drilling tool; placing a hole-sealing grouting pipe and a fracture grouting pipe into each of the directional fracture holes; and injecting including the steps of firstly injecting a small amount of polymer material into the sealing-hole pipe, and secondly injecting predetermined amount of material into the fracture grouting pipe. Under the chemical reaction, the mixed material expands, fractures the soil along the guided directions, and forms a super thin polymer segment. Finally, the polymer segments are overlapped each other, and the seepage control system is constructed inside the dike or dam.
