Description
Technical Field
The utility model belongs to the technical field of drain hole dredging, and particularly relates to a dredging device for a drain hole of a retaining wall.
Background
The drain hole of the retaining wall of the hydropower station is damaged under the action of long-time slope water seepage, so that a large amount of sand blocks the drain hole. The retaining wall table back stress is gradually increased due to the fact that the retaining wall table back is not drained in time when water seepage occurs to the retaining wall table back, the bearing capacity of the foundation is reduced due to the fact that the retaining wall foundation runs off soil, collapse of the retaining wall due to overall instability of the retaining wall is prone to occurring, meanwhile, partial water seepage is conducted through the retaining wall body seepage portion, long-time water is analyzed out, the wall surface is dirty, and overall attractiveness is affected.
In the prior art, when an iron borer and a steel bar are generally used for dredging a drain hole with a distance of more than 1.5m, the iron borer and the steel bar are increased in winding degree and are easy to bend, the front section cannot be stressed, and the dredging capability is reduced; the head of the iron chisel is easy to bend and deform under the impact action of rock hard objects. The simple use of the iron fiber for dredging wastes time and labor, and the effect is not good enough.
Therefore, it is very critical to develop a dredging device for a drain hole of a retaining wall, which can solve the above problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a dredging device for a drain hole of a retaining wall.
The utility model aims to realize the purpose, the drilling tool comprises a drilling bit and a connecting rod, the drilling bit and the connecting rod are fixedly connected, a hole expander is arranged at the front end of the connecting rod, the hole expander comprises a sleeve, a transmission ring capable of moving on the sleeve is arranged on the periphery of the sleeve, three first transmission rods are rotatably connected onto the transmission ring, the first transmission rods are rotatably connected with end points of a supporting strip, the other end of the supporting strip is rotatably connected with end points of a second transmission rod, the other end of the second transmission rod is rotatably connected with the sleeve, a pushing bolt is fixedly connected onto the transmission ring, and the connecting rod can rotate in the sleeve.
Compared with the prior art, the utility model has the following technical effects:
in order to prevent the friction between the drill bit and the connecting rod and the wall of the drain hole caused by the overlong length of the tool during dredging operation, the utility model designs the hole opener (the applicable pipe diameter range is 50mm-150mm, and the drill bit and the connecting rod are prevented from contacting the wall of the drain pipe), and manual tunneling is carried out, and meanwhile, the drill bit and the connecting rod are not designed to be a middle hole, so that the water seepage in the tunneling process can be conveniently and timely removed. The operation saves time, is simple and convenient, the design field does not need to provide electric power, the time can be realized by single person through simple assembly, and the application range is wide.
