An anti-slide pile with retaining anchor for slope

Abstract

The invention discloses a novel side slope retainer anchor anti-sliding pile, which comprises a cylindrical pile body and is characterized in that a cylindrical cavity is arranged in the pile body, a plurality of water filtering holes are uniformly distributed in the axial direction of the pipe body, a water discharge pipe is arranged in the cylindrical cavity, broken stone is filled at the gap part of the cylindrical cavity, a water outlet of the water discharge pipe is connected with an external vacuum pump, the novel side slope retainer anchor anti-sliding pile also comprises an anchor rod body with the round cross section, the anchor rod body passes through the pile body, an included angle between the anchor rod body and the pile body is 15 to 25 DEG C, the anchor rod body comprises a plurality of sections of coaxially and integrally formed rod body sections, and the diameter of the rod body sections is sequentially reduced from the rod head of the rod body to the rod tail. The novel side slope retainer anchor anti-sliding pile has the advantages that the anti-sliding effect and the water discharge are integrated, in addition, the bending resistance intensity is improved, and meanwhile, the bite force and the friction force between the anchor rod and the mortar are improved.

Description

technical field [0001] The invention relates to a pile body used for construction, in particular to a side slope retaining anchor tension anti-slide pile. Background technique [0002] Generally speaking, my country is a mountainous country, especially in the southern region. Not only are there many mountains, but also there is abundant rain in summer, which leads to the increase of rock-soil bulk density and rock softening, reduces the shear strength of rock-soil, and produces net water pressure and hydrodynamic force. Scouring or submerged erosion of the slope toe lubricates the overlying strata of the impermeable layer soil, and when the top surface of the impermeable layer gathers into layers, it also produces buoyancy to the overlying strata. Therefore, landslides and mudslides frequently occur in summer in the southern region, especially in mountainous areas, which is detrimental to the traffic and personal safety of local people. In early August this year, Typhoon Hai...

Problems solved by technology

Anti-slide piles, as a pile for stabilizing landslides, have remarkable effects. However, in terms of their materials, anti-slide piles currently on the market include concrete piles, reinforced concrete piles, and steel piles, and these anti-slide piles either have poor tensile properties, Either the corrosion resistance is poor, and its permeability coefficient is often 10 －7 m / s, while the front edge of the landslide body has a larger permeability coefficient, often greater than 10 －5 m / s, therefore, the reinforced concrete anti-slide pile is a water-resisting layer relative to the slide body, and the result is that the dense rows of piles in the middle and lower part of the slope form a vertical seepage barrier virtually, blocking the water coming from the rear edge of the slope The groundwater cannot be discharged in time, which raises the groundwater level in the middle and front of the slope, increases the saturation of the soil in the local area of ​​the landslide mass, causes the gravity of the slide to increase, and the comprehensive cohesion and internal friction angle of the slide zone decrease. The anti-sliding force decreases and the sliding force increases, which increases the potential danger of landslides to a certain extent, and the comprehensive anti-sliding effect of anti-sliding piles decreases.

[0004] At present, anchors are often used to reinforce slopes, but the existing anchors have the following disadvantages: the cross-section of the anchor is equal, and the bond strength between the anchor and the mortar is not high; the material used for the anchor is mainly steel bars, often due to corrosion and failure; the weight of the anchor itself is large, and the construction is difficult; the anchor is easy to conduct electricity, which will cause underground dust explosions, etc.
