Abstract

The invention relates to a method that cement mixed soil curtain implants lateral force resistance pile of prefabricated reinforced concrete. Main procedures are described as follows. In construction site, cement mixer is used to mix soil in the whole journey or in upper water-stopping curtain part to form curtain along the implanting depth aiming to soil quality and soil extruding status; then it is implanted into pile body by pile driver to form retaining and waterproof enclosure wall. Thereinto pile body adopts prefabricated reinforced concrete T-shape/ I-shape pile. Because powerful mixing soil or drilling machine is used to dig hole and inject grout, it is suitable for enclosure project of all kinds of soil qualities in principle. The beneficial effect of invention is that reinforcement ribs of T-shape or I-shape section are located at two ends of section; compared with circular pile with reinforcement ribs distributed along round face, the bending strength can be improved by more than 20% and the section area only is half of corresponding circular pile, namely concrete amount is saved in half. Ant it is provided with rapid construction speed, reliable quality, no noise and no pollution to circumstance by carrying slurry out so on.

Description

The method of a kind of cement purdah into prefabricated reinforced concrete lateral force resistance stake
Technical field
The present invention relates to a kind of lateral force resistance prefabricated reinforced concrete T shape/I-shaped job practices that is used to go along with sb. to guard him engineering and stability of slope engineering, the method for especially a kind of cement purdah into prefabricated reinforced concrete lateral force resistance stake.
Background technology
At present in bracing of foundation pit engineering and the stability of slope engineering, the normal enclosure wall that adopts the stake of steel bar concrete circle in conjunction with cement mixing pile formation also has the stake of the vibration sinking tube of employing T shape to replace circle stake or employing SMW worker method (implant callable large-scale i shaped steel in the soil-cement and form enclosure wall).
The stake of steel bar concrete circle is traditional worker's method, and the cost height is arranged, and speed of application is slow, shortcomings such as construction mud contamination environment; SMW worker's method also exists and reclaims shortcomings such as shaped steel, cost is higher; Though immersed tube T shape stake cost is all lower than above-mentioned worker's method, exists speed of application slow relatively, and shortcoming such as construction quality instability.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides that a kind of anti-side direction ability is good, cost is low, construction quality is stable, speed is fast, the method for the cement purdah into prefabricated reinforced concrete T shape/I-shaped lateral force resistance stake of noiselessness, nothing (lacking) soil compaction.
The present invention solves the technical scheme that its technical problem adopts: the method for this cement purdah into prefabricated reinforced concrete lateral force resistance stake, mainly comprise the steps: at the construction field (site) earlier with the implantation depth of cement mixer along pile body, look soil property and soil compaction situation, omnidistance stirring soil or top water-stop curtain partly stir soil and form curtain, implant pile body with pile press then, make and form the native sealing enclosure wall of retaining, wherein pile body adopts the prefabricated T shape of steel bar concrete/I-shaped stake, owing to adopt powerful stirring soil or rig to draw hole slip casting, be applicable to the engineering of going along with sb. to guard him of all kinds of soil properties in principle.
Cement mixer stirs to form and is convenient to implant the agitation pile curtain of the anti-side direction stake of prefabricated reinforced concrete among the present invention, and the curtain way can have following various way.
Pile body of the present invention cross section mainly comprises first wing plate and web, and first wing plate links to each other with web and constitutes T shape, and the angle α of first wing plate and web both sides is greater than 90 °, less than 135 °.
The other end of web of the present invention be connected with second wing plate and structure I-shaped, the angle β of second wing plate and web both sides is greater than 90 °, less than 135 °.
The present invention is provided with steel bar stress on two ends of the cross section of pile body, connect with stirrup between the steel bar stress, and under different depth, edge of a wing part pressurized or tension are calculated configuration reinforcement by theory, all can satisfy the stressed and deformation requirements of space enclosing structure.
Pile body of the present invention is the plain bars concrete or is the prefabricated T shape of prestressed reinforced concrete/I-shaped stake.
The effect that the present invention is useful is: the arrangement of reinforcement of T shape or I-shaped cross-section is positioned at cross section two ends, comparing arrangement of reinforcement improves more than 20% along the circle stake flexural strength of circumference, and sectional area only is corresponding circle stake half, promptly save the concrete consumption half, thereby comprehensive cost saves 20%~30% than traditional round stake, and it is fast to have a speed of application, reliable in quality, there is not (low) noise, advantages such as no mud outward transport contaminated environment.And owing to powerful stir the soil body or the hole is drawn in boring slip casting, replant into lateral force resistance T shape/I-shaped stake, thereby in principle applicable various soil properties go along with sb. to guard him engineering and stability of slope engineering.
