Embodiment 1

[0024] Embodiment 1: the anti-sliding pile 8 of a kind of T-shaped cross-section provided by the present invention, its structure is as follows figure 1 As shown, it is formed by pouring reinforced concrete. The cross-section of the poured reinforced concrete anti-slide pile is similar to a T shape. Between the pile front end 2 is an arc-shaped body part 3, and the transverse width of the pile rear end 1 is longer than the transverse width of the pile front end 2.

[0025] The stress distribution on the anti-slide pile cross section of the present invention is as follows: figure 2 As shown, the force on the rear end 1 of the anti-sliding pile is tensile stress, which belongs to the tension zone 4, and the force on the front end 2 of the pile and the front part of the arc body part 3 is mostly compressive stress, which belongs to the compression zone 5. In the reinforcement cage 6 installed inside the slide pile, denser steel bars 7 should be arranged at the pile rear end 1 o...

Embodiment 2

[0029] Embodiment 2: The anti-slide pile 8 with a T-shaped cross-section provided in Embodiment 1 of the present invention is used for construction. Since the construction section of the anti-slide pile is small, mechanical construction can be used for construction. The construction steps are as follows:

[0030] (1) Level the site, and measure and locate the center point of the anti-slide pile according to the design drawings. The distance between the centers of adjacent anti-slide piles is slightly larger than that of conventional rectangular anti-slide piles.

[0031] (2) Equipment in place, including digging equipment such as excavators, bulldozers, rock drills, safety equipment such as safety helmets, seat belts, and software, wall protection equipment such as formwork and support frames, electric welding machines, cranes, etc., steel bar processing and installation equipment, etc. Ready.

[0032] (3) Excavating holes, using excavators and rock drills to excavate the roc...

Abstract

The invention relates to an antiskid pile with a T-shaped cross section. The antiskid pile is formed by pouring reinforced concrete, the cross section of the antiskid pile is in a shape of a T, the top of the T serves as a front end of the pile, the bottom of the T serves as a rear end of the pile, an arc-shaped part is formed between the front end and the rear end of the pile, the design of the arc-shaped part can prevent stress concentration from being generated at a pointed position, rebar cages are mounted in the antiskid pile, dense rebars are arranged in the rebar cage at the rear end of the pile, and few rebars are arranged at the front end and the arc-shaped part. The transverse width of the rear end of the pile is larger than that of the front end of the pile, so that soil arching effect behind the pile can be brought into full play, and during slope treatment, the distance of pile centers between adjacent antiskid piles can be increased while the number of the antiskid piles needed to be arranged is decreased correspondingly; and in addition, the area of the antiskid pile with the T-shaped cross section is evidently smaller than that of an antiskid pile with a rectangular cross section, so that concrete and the rebars can be greatly saved, and cost is lowered. The antiskid pile is small in construction section, convenient for mechanical construction, simple and safe in construction and wide in popularization and application prospect.

Description

technical field [0001] The invention relates to a reinforced concrete anti-slide pile for slope engineering and landslide treatment engineering, in particular to an anti-slide pile with a T-shaped cross section, which belongs to the technical field of slope or slope stabilization. Background technique [0002] There are many ways to control slopes and landslides, among which setting anti-slide piles is a very widely used control scheme. The anti-slide principle of anti-slide piles is that the anti-slide piles rely on the anchoring effect and passive resistance of the part below the sliding surface to jointly balance the landslide thrust acting on the piles; The landslide thrust generated; when the pile distance of the anti-slide piles is within a certain range, the soil arch effect can be formed by means of the load-bearing section of the pile, the soil on the back of the pile and the friction on both sides of the pile, so that the sliding body will not slip out from between...
