Abstract
The utility model discloses a novel steel sheet pile which is characterized by comprising a water supply pipe and an air supply pipe. Both the water supply pipe and the air supply pipe are vertically fixed downwards in grooves at the inner side of the steel sheet pile. A fixing steel plate is installed in the grooves at the inner side of the steel sheet pile. The water supply pipe and the air supply pipe are fixed in the grooves by the fixing steel plate. The water supply pipe and the air supply pipe are circular pipes with cone-shaped lower ends. The water supply pipe and the air supply pipe are arranged in parallel. A water supply hose connected with a water pump is installed at the upper end of the water supply pipe, and an air supply hose connected with an air compressor is installed at the upper end of the air supply pipe. In the novel steel sheet pile, high-pressure air and water are respectively introduced through the water supply pipe and the air supply pipe installed at the inner side of the steel sheet pile to disperse cobbles by water and carry the cobbles out by forming a lot of bubbles in the water by the high-pressure air so as to generate larger upward buoyancy.
Description
Technical field
The utility model relates to a kind of new type of steel plate stake.
Background technology
Steel sheet-pile cofferdam is the temporary structure of building and bridge foundation construction, and setting of steel sheet pile is directly to adopt vibration hammer to insert to beat, and when running into bigger cobble, is difficult to insert and gets to design elevation, wastes time and energy, and incured loss through delay the progress of construction.
The utility model content
The utility model technical problem to be solved provides a kind of new type of steel plate stake, has solved the problems referred to above.
The utility model technical problem to be solved realizes through following technical scheme:
A kind of new type of steel plate stake is characterized in that: comprise feed pipe and air supply pipe, said feed pipe and air supply pipe all are fixed in the inboard groove of steel sheet pile straight down.Said steel sheet pile cross section is
shape, and the outer end of dual-side outwards bends.It is rectangular-shaped that the pile crown of said steel sheet pile is isosceles.
In the said steel sheet pile inboard groove fixation steel plate is installed, said feed pipe and air supply pipe are fixed in the groove through this fixation steel plate.
Said feed pipe and air supply pipe are the lower end and are cone shape pipe.
Said feed pipe and air supply pipe laterally arrange.
Said feed pipe upper end is equipped with the water supply hose of water pump.
Said air supply pipe upper end is equipped with the air supply hose that is connected with air compressor machine.
The beneficial effect of the utility model:
The utility model has passed through in the steel sheet pile installed inside tracheae and water pipe, and logical respectively gases at high pressure and water break up cobble through water, in water, form a large amount of bubbles through high pressure gas, cause producing bigger buoyancy upwards, and cobble is carried out.

As shown in the figure, 1-steel sheet pile, 2-feed pipe, 3-air supply pipe, 4-fixation steel plate, 5-water supply hose, 6-air supply hose.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further.
Shown in Fig. 1-2, a kind of new type of steel plate stake is characterized in that: comprise feed pipe 2 and air supply pipe 3, said feed pipe 2 all is fixed in the groove of steel sheet pile 1 inboard with air supply pipe 3 straight down.
In said steel sheet pile 1 inboard groove fixation steel plate 4 is installed, said feed pipe 2 is fixed in the groove through this fixation steel plate 4 with air supply pipe 3.Said steel sheet pile cross section is
shape, and the outer end of dual-side outwards bends.It is rectangular-shaped that the pile crown of said steel sheet pile is isosceles.
Said feed pipe 2 is the lower end with air supply pipe 3 and is cone shape pipe.
Said feed pipe 2 laterally arranges with air supply pipe 3.
Said feed pipe 2 upper ends are equipped with the water supply hose 5 of water pump.
Said air supply pipe 3 upper ends are equipped with the air supply hose 6 that is connected with air compressor machine.
When conventional steel sheet pile is difficult to be inserted into design elevation; Adopt the conventional steel sheet pile of same model to make described high pressure air water steel sheet pile; To feed pipe and air supply pipe fixing in the high pressure air water steel sheet pile inboard groove; Logical respectively water under high pressure and pressure-air, the hole is drawn at the place in the stake position, and then inserts and beat conventional steel sheet pile and put in place.
To feed pipe 2 and air supply pipe 3; In the time of logical water under high pressure and pressure-air, cooperate vibrating hammer to insert and beat, along with high pressure air water steel sheet pile sinks; Closely knit boulder bed under the high pressure air water steel sheet pile end is towards loose; The small particle diameter sandstone forms hole with floating to the riverbed on the water under high pressure gas mixture, thereby makes the anchorage depth of steel sheet pile can reach design.
