Abstract
The present invention relates to one kind block water occlusion steel-pipe pile, the open slot that H profile steel and two blocks of unequal angle irons including steel-pipe pile main body and positioned at steel-pipe pile main body both sides are constituted, one vertical edge of the H profile steel can be caught in open slot, the long side of the vertical edge and two blocks of unequal angle irons constitutes a rectangular hole, and water-swellable agent is filled in the hole.Total simple installation, speed of application is fast, and sealing performance is excellent, while can substantially reduce construction investment, accelerates construction progress, and reduces construction procedure.
Description
Technical field
The present invention relates to foundation pit exterior-protected device field, specifically a kind of occlusion steel-pipe pile that blocks water.
Background technology
Deep, big Foundation Pit Support Engineering at present, mainly adds cement mixing pile to block water using on the outside of cast-in-situ bored pile.
Small-sized, shallower Foundation Pit Support Engineering equally adds cement mixing pile using Larsen steel sheet pile and steel pipe pile as fender post, outside
To block water.There are leakage problems as foundation pit enclosure for existing steel-pipe pile, it is necessary to increase cement mixing pile on the outside
It blocks water, entire engineering construction is complicated, and progress is slow, and cost is higher.
Invention content
Technical problem to be solved by the invention is to provide one kind block water occlusion steel-pipe pile, with solve exist in the prior art
Defect.
The technical solution that the present invention solves above-mentioned technical problem is as follows：
One kind, which blocks water, is engaged steel-pipe pile, including steel-pipe pile main body and the H profile steel and two positioned at steel-pipe pile main body both sides
The open slot that block unequal angle iron is constituted, a vertical edge of the H profile steel can be caught in open slot, the vertical edge and two pieces of inequilaterals
The long side of angle bar constitutes a rectangular hole, and water-swellable agent is filled in the hole；
Further, the H profile steel and two blocks of unequal angle irons are welded and fixed with the steel-pipe pile main body；
Further, the water-swellable agent is that fluffy soil, expanding cement and organic expander mix；
Further, it is welded with triangular reinforcing plate on the outside of two blocks of unequal angle irons；
The beneficial effects of the invention are as follows：Total simple installation, speed of application is fast, can substantially reduce construction investment,
It accelerates construction progress, reduces construction procedure.
Description of the drawings
Fig. 1 is one structural schematic diagram of the embodiment of the present invention；
Fig. 2 is two structural schematic diagram of the embodiment of the present invention；
The reference numerals are as follows：
1, steel-pipe pile main body, 2, H profile steel, 3, unequal angle iron, 4, hole, 5, water-swellable agent, 6, triangular reinforcing plate；
Specific implementation mode
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
As shown in Figure 1 for embodiment 1 one kind block water occlusion steel-pipe pile, including steel-pipe pile main body 1 and be located at the steel pipe
The open slot that the H profile steel 2 of 1 both sides of stake main body and two blocks of unequal angle irons 3 are constituted, a vertical edge of the H profile steel 2 can be caught in opening
In slot, the long side of the vertical edge and two blocks of unequal angle irons constitutes a rectangular hole 4, and water-swellable is filled in the hole 4
Agent 5；
More specifically, the H profile steel 2 and two blocks of unequal angle irons 3 are welded and fixed with the steel-pipe pile main body 1；
More specifically, the water-swellable agent 5 is that fluffy soil, expanding cement and organic expander mix；
Fig. 2 show specific embodiment 2 one kind block water occlusion steel-pipe pile, on the basis of specific embodiment 1, in institute
The outside for stating two blocks of unequal angle irons 3 is welded with triangular reinforcing plate 6；
Specific work process is as follows：
1, using giant punching, borehole cleaning exposes certain space.
2, flexible expansion agent is injected in hole using mortar pump.
3, flexible expansion agent profession is prepared：Main component is bulk soil, expanding cement, organic expander etc., by certain ratio
Example synthesis.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
