Abstract
The utility model concerns a T-shaped or I-shaped lateral force resistant pile of preformed reinforced concrete, including a pile body which is a reinforced concrete preformed pile. The section of the pile mainly includes a first alar plate and a ventral plate which are connected to form a T shape. The angle alpha between the first alar plate and the both sides of the ventral plate is from 90 degrees to 135 degrees. The other end of the ventral plate of the utility model is connected with a second alar plate to form the I shape and the angle beta between the second alar plate and the both sides of the ventral plate is from 90 degrees to 135 degrees. The beneficial effect of the utility model is that the reinforcing bars of the T-shaped or I-shaped section are arranged at the both sides of the sections and compared with the round pile on which the reinforcing bars are arranged along circumference, the buckling strength is improved more than 20 percent, besides the section area is only one half of the corresponding round pile, that is to say, the concrete can be saved one half. As a result, compared with the traditional round pile, the integrative cost is saved about 20 percent to 30 percent. The utility model has the advantages of fast construction speed, credible quality, no (less) noise and no environmental pollution caused by the slurry carried out.
Description
Technical field
The utility model relates to a kind of lateral force resistance prefabricated reinforced concrete member that is used to go along with sb. to guard him engineering and stability of slope engineering, especially a kind of prefabricated reinforced concrete T shape/I-shaped 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 need to reclaim 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 utility model 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 prefabricated reinforced concrete T shape/I-shaped lateral force resistance stake of noiselessness, nothing (lacking) soil compaction.
The utility model solves the technical scheme that its technical problem adopts: this prefabricated reinforced concrete T shape/I-shaped lateral force resistance stake, comprise pile body, described pile body is the steel bar concrete preformed pile, its pile body cross section mainly comprises first wing plate and web, first wing plate links to each other with web and constitutes T shape, the angle α of first wing plate and web both sides is greater than 90 °, less than 135 °.
The other end of web described in the utility model 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 utility model is provided with steel bar stress on two ends of the cross section of pile body, connect with stirrup between the steel bar stress, forms bending resistance component.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 described in the utility model is a plain bars concrete preformed pile or for giving stress steel bar concrete preformed pile.
The utility model adopts soil-cement to stir or top stirring back implantation T shape or I-shaped preformed pile along the stake total length, and also available pile press is powerful to be implanted in the soil, is used as the native sealing enclosure wall of retaining in bracing of foundation pit engineering or the stability of slope engineering; 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.
The effect that the utility model 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.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1: as shown in Figure 1, the stake of this prefabricated reinforced concrete T shape lateral force resistance comprises pile body 1, and pile body 1 is provided with reinforcing bar 2 for plain bars concrete preformed pile or for giving stress steel bar concrete preformed pile on two ends of the cross section of pile body 1.Pile body 1 cross section mainly comprises the first wing plate 1-1 and web 1-2, and the first wing plate 1-1 links to each other with web 1-2 and constitutes T shape, and the angle α of the first wing plate 1-1 and web 1-2 both sides is greater than 90 °, less than 135 °.
Produce the stake of steel bar concrete T shape in precast yard, adopt specially designed T shape mould, mould should bear to give and adds stress.Hang in maintenance in the steam curing pond after building concrete, reach that lifting is transported to the building site after the intensity.Prefabricate if it is long to need to increase stake, can be adopted, pile extension in the site operation in stake long≤16 meter of prefabricated T shape stake.
At the construction field (site) earlier with powerful single shaft, twin shaft or three cement mixers implantation depth along T shape or I-shaped, look soil property and soil compaction situation, omnidistance stirring soil or top water-stop curtain partly stir soil, implant the stake of prefabricated reinforced concrete T shape with pile press then, make to form the native sealing enclosure wall of retaining.As shown in Figure 3, cement mixer stirs and forms the single agitation pile curtain 3 of minor diameter, and at agitation pile of T stake place evagination, makes with the size of T shape stake to cooperate, so that implant the stake of T shape.As shown in Figure 4, cement mixer stirs and forms single major diameter agitation pile curtain 3, implants the stake of T shape, so forms space enclosing structure, and it is better than shown in Figure 3 that it keeps off native stagnant water effect.
