When the assembled hollow square pile underground continuous wallboard is used as a supporting and protecting structure, the assembled hollow square pile underground continuous wallboard can be used for baffling soil, stopping water and structuring, the rigidity is large, the pouring is performed on the spot, the reinforcing steel bar is configured according to the condition of the soil property and the size of the soil pressure, the intensity and the rigidity are easily adjusted, the engineering cost is low, and the construction cost can be greatly reduced.
Description
Technical field
The utility model relates to stake and the foundation pit supporting construction in the civil construction project, particularly a kind of hollow concrete pile, and with the reinforced concrete combined wall plate of this side stake formation.
Background technology
At present in foundation pit supporting construction, method commonly used has bored pile, diaphragm wall, forms such as SMW worker's method, wherein the drill-pouring pilework can only be kept off soil, can not sealing, still need and join water-stopping structure in addition, can finish the prop function, though SMW worker's method can be accomplished to keep off native sealing and be united two into one, but because of its rigidity is little, distortion is big and be subjected to many restrictions, and traditional continuous underground wall structure promptly can keep off soil again can sealing, but mud displacement is big during its construction, cost is higher again, is difficult to use in the general engineering go the prefabricated tubular pile composite support wallboard (patent No. 200620125443.4) of my utility model, it is big to have the supporting rigidity, economic and reliable, easy construction, the retaining soil plurality of advantages such as unite two into one that blocks water, but because pile tube is prefabricated units, it is not very flexible that the strength and stiffness of supporting wallboard are regulated.Some ' worker ' is though that the font mould can be accomplished retaining soil, sealing, wall body structure is three-in-one, but because it is the grid diaphragm wall that is formed by ' worker ' font mould, his binding site is the two Ge Yi Vela of ' worker ' font, bonding surface is less relatively, and binding site becomes the weak link of sealing easily.
Summary of the invention
Technical problem:It is three-back-shaped concrete pile and assembled wall board thereof that the purpose of this utility model aims to provide a kind of cross section, this three-back-shaped concrete pile can independently use as engineering piles or soldier pile, also can arrange construction and form underground continuous wall plate, it has overcome the deficiencies in the prior art, when combined hollow side's stake underground continuous wall plate is used in supporting and protection structure, can accomplish retaining soil, sealing, structure is three-in-one, and rigidity is big, in-site pouring, reinforcing bar is with the soil property situation, the size configure of soil pressure, strength and stiffness are easy to regulate, and construction costs is low, can reduce engineering cost significantly.
Technical scheme:Cross section of the present utility model is three-back-shaped concrete pile and assembled wall board thereof, and it is square to be long (accurate long), and the core of stake is the soil body, during independent the use, can be used as engineering piles or soldier pile; When continuous arrangement construction, promptly formed combined wall panel, be the soil body in the hollow core portion of three-back-shaped concrete pile, assembled wall board is according to stressed size configure reinforcing bar, and concreting, promptly can keep off native sealing thereby form, can bear the supporting and protection structure of external force again.
Cross section of the present utility model is that three-back-shaped concrete pile is a hollow-core construction, between the inwall of hollow concrete pile and outer wall, be provided with square reinforcing cage, be filled between the inwall of concrete pile and the outer wall and wrap up square reinforcing cage by concrete, be provided with three-back-shaped stake point in the bottom of hollow concrete pile.
Cross section is that three-back-shaped concrete pile assembled wall board is combined by a plurality of hollow concrete piles that are arranged side by side, between per two adjacent hollow concrete piles, be provided with shaped steel, the three-back-shaped stake point that is positioned at the hollow concrete pile bottom has inclined to one side point, be back hollow side's stake stake point with the contacted side of previous hollow side stake, parallel sidewalls with hollow concrete pile, the inclined-plane of stake point is monolateral inside skew back, and the stake point on other three limits is that v font two limits are oblique.
Beneficial effect:With traditional diaphragm wall, and compare with grid-like underground continuous wall plate, the utility model has plurality of advantages:
1) because the core of three-back-shaped concrete pile is a undisturbed soil, can economical with materials, reduce cost.
2) water not in the process of construction, not only using water wisely, but also do not have the discharging and the transportation problem of mud.
3) owing to having adopted steel form, so overcome the collapse hole and the undergauge problem of traditional diaphragm wall.
4) this supporting and protection structure retaining soil, sealing and outer wall of basement are three-in-one, save space, save cost.
5) contact surface between two ' returning ' fonts is than big many of the contact surface between two ' worker ' fonts, thereby greatly strengthened the anti-permeability performance of contact surface.
6) square-section is big than the intensity of I-shaped cross-section, good rigidity, and the globality height, therefore, the performance by I-shaped diaphragm wall that forms is good for the diaphragm wall that is formed by the stake of hollow side.
