Description
Technical field
The present invention relates to the realm of building construction, particularly relate to a kind of cement-soil retaining wall perfusion campshed and construction method thereof.
Background technology
Along with the development of engineering construction cause, piling Technology has had a lot of breakthrough, and new pile-type and construction technology and facility supporting with it continue to bring out.As everyone knows, boring conventional at present and Punching Borehole Cast-in-place Concrete Pile all adopt mud off mode, in pore forming process, can produce stress relaxation phenomenon, and the pit protection mud cake formed after pore-forming can weaken a side skin friction, sediment of the hole bottom can weaken bearing capacity of pile tip, a large amount of mud produced during pore-forming pollutes the environment and causes secondary public hazards, and be difficult to accomplish tangent between stake, leave certain gap between stake, thus need separately to do water-stop curtain etc., add the input cost of engineering.
Summary of the invention
For solving the problem, the invention provides a kind of can the cement-soil retaining wall perfusion campshed and construction method thereof of dash better effects if.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cement-soil retaining wall perfusion campshed, comprises some agitation piles arranged according to cement-soil retaining wall castinplace pile supporting and protection structure bearing of trend, and arbitrary agitation pile all has and is partially submerged in another adjacent with it agitation pile, is equipped with castinplace pile in each agitation pile.
Be further used as the improvement of technical solution of the present invention, agitation pile is cylindric.
Be further used as the improvement of technical solution of the present invention, two adjacent agitation piles intersect, and the thickness intersected is not less than 100mm.
A construction method for above-mentioned cement-soil retaining wall perfusion campshed, is characterized in that, comprise the following steps:
1) cement mixing method design stake circle of position center is aimed at the stirring-head center of soil-cement stirring, stirs while sink down into the projected depth of agitation pile, water-spray type slurry stirs, promotes stirring-head to the design stake top degree of depth of agitation pile, form the 1st agitation pile;
2) according to the bearing of trend mixer of cement-soil retaining wall castinplace pile supporting and protection structure on the position of next root agitation pile, repeat step 1), complete next root agitation pile;
3) after the 1st mixing pile construction terminates to be no less than 72 hours, rig is moved on the position of the 1st agitation pile, drill hole of drilling machine fetches earth, to the projected depth of cast-in-place concrete pile;
4) holed, carried out hole clearly, put reinforcing cage, concrete perfusion, formed the 1st castinplace pile;
5) rig moves on the position of next root agitation pile, repeats operation 3), complete next root castinplace pile.
Be further used as the improvement of technical solution of the present invention, two adjacent agitation piles intersect, and the thickness intersected is not less than 100mm.
Beneficial effect of the present invention: this perfusion campshed comprises some agitation piles arranged according to cement-soil retaining wall castinplace pile supporting and protection structure bearing of trend, each agitation pile all will be partially submerged in another adjacent with it agitation pile simultaneously, carry out in the process of borehole slip casting at this type of filling pile structure of construction, agitation pile grouting agent can be saved, the method construction pile fast and pile quality be easy to control and transfer reinforcing cage complete cast after each cylindrical shape stake intersect each other, the water-retaining capacity of whole row's castinplace pile entirety can be strengthened.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is agitation pile structural representation in the present invention.
Detailed description of the invention
With reference to Fig. 1, the present invention is a kind of cement-soil retaining wall perfusion campshed, comprise some agitation piles 1 arranged according to cement-soil retaining wall castinplace pile supporting and protection structure bearing of trend, arbitrary agitation pile 1 all has and is partially submerged in another adjacent with it agitation pile 1, is equipped with castinplace pile 2 in each agitation pile 1.
As the preferred embodiment of the present invention, agitation pile 1 is cylindric.
As the preferred embodiment of the present invention, two adjacent agitation piles intersect, and the thickness intersected is not less than 100mm.
A construction method for above-mentioned cement-soil retaining wall perfusion campshed, is characterized in that, comprise the following steps:
1) cement mixing method design stake circle of position center is aimed at the stirring-head center of soil-cement stirring, stirs while sink down into the projected depth of agitation pile 1, water-spray type slurry stirs, promotes stirring-head to the design stake top degree of depth of agitation pile 1, form the 1st agitation pile 1;
2) according to the bearing of trend mixer of cement-soil retaining wall castinplace pile supporting and protection structure on the position of next root agitation pile 1, repeat step 1), complete next root agitation pile 1;
3) when the 1st agitation pile 1 is constructed after end is no less than 72 hours, rig is moved on the position of the 1st agitation pile 1, drill hole of drilling machine fetches earth, to the projected depth of cast-in-place concrete pile 2;
4) holed, carried out hole clearly, put reinforcing cage, concrete perfusion, formed the 1st castinplace pile 2;
5) rig moves on the position of next root agitation pile 1, repeats operation 3), complete next root castinplace pile 2.
This perfusion campshed comprises some agitation piles 1 arranged according to cement-soil retaining wall castinplace pile supporting and protection structure bearing of trend, each agitation pile 1 all will be partially submerged in another adjacent with it agitation pile 1 simultaneously, carry out in the process of borehole slip casting at this type of filling pile structure of construction, the grouting agent of agitation pile 1 can be saved, and transfer reinforcing cage complete cast after each cylindrical shape stake intersect each other, the water-retaining capacity of whole row's castinplace pile entirety can be strengthened.
