The Chinese invention patent being CN103266619A as a patent publication No. discloses a kind of cofferdam, comprise and be combined into frame closed structure by multiple side, it is characterized in that, also comprise the first watertight shutter and the second watertight shutter, wherein said first watertight shutter is arranged on the top mouth of described frame closed structure, described second watertight shutter is arranged on the end mouth of described frame closed structure, and the first side in described first watertight shutter, described second watertight shutter and described multiple side connects as one, described first side be cofferdam lie on one's side lower water time the side that first contacts with the water surface.
Above-mentioned cofferdam volume ratio is comparatively large, need to check job site by boats and ships simultaneously and carry out assembling construction, such cost is very high, and speed of application is slow, constructs for some small-sized bridge piers, does not need volume large-scale like this.Therefore, be badly in need of one and be applicable to small-sized bridge pier cofferdam construction device.
Summary of the invention
The utility model is for above shortcoming, large based on solution existing highway bridge construction cofferdam volume, the problem that cost is high.Propose a kind of shallow water Bridge Pier Construction cofferdam device, this equipment mechanism is reasonable in design, flexible for installation, and cost is low, and speed of application is fast.
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of shallow water Bridge Pier Construction cofferdam device, comprising from boring stake and waterstop, it is characterized in that: be provided with right angle outside the stake of described brill certainly and connect fixture block, and waterstop two ends are stuck in right angle and connect formation cofferdam in fixture block; Described certainly boring bottom stake is provided with Electric drill-bit, and supply line's connection Electric drill-bit is also connected with external power source, is provided with main drinking-water pipe from boring in stake, is provided with the branch's drinking-water pipe be connected with main drinking-water pipe between the described right angle connection fixture block certainly boring stake.
Preferentially, the uniform setting from top to bottom of described branch drinking-water pipe, water inlet is provided with screen pack.
Preferentially, connection fixture block lower end, described right angle is also provided with rectangular.
Preferentially, described supply line periphery is also provided with protection tube.
Preferentially, described is helical structure from boring stake bottom.
Preferentially, described waterstop is connected between fixture block with right angle and is also provided with rubber pad.
Compared with prior art, advantage of the present utility model is as follows: drive waterstop to squeeze in the earth in water by utilizing from boring stake, and draw water, device is flexible for installation, and cost is low, and speed of application is fast, is applicable to promoting the use of.
