Description

Technical Field

[0001] This utility model relates to the field of anti-slide pile technology, and in particular to an anti-slide pile structure for rock and soil slope protection. Background Technology

[0002] Anti-slide piles are engineering structures used to prevent landslides and stabilize slopes. Their main body is a reinforced concrete pile that penetrates into a stable stratum. They resist landslide thrust through the interaction between the pile body and the surrounding rock and soil. Anti-slide piles are usually arranged vertically or inclinedly at the leading edge of the landslide body or near the potential sliding surface. By utilizing the bending stiffness of the pile and the anchoring force of the anchoring section, the landslide thrust is transferred to the stable stratum, thereby preventing the landslide body from sliding.

[0003] According to the construction technology, anti-slide piles can be divided into bored piles, excavated piles, etc. Among them, rectangular piles are the most widely used. However, a single pile body relies on passive earth pressure and is prone to cracking due to concentrated thrust. Moreover, the moment of inertia of the cross section is limited, and the size needs to be increased, resulting in material waste. Furthermore, traditional pile retaining structures mostly use prefabricated components spliced ​​on site, and the connection nodes are prone to becoming weak links in the stress, and the installation time is relatively long. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-slide pile structure for rock and soil slope protection, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anti-slide pile structure for rock and soil slope protection includes a pile body, tensile seats fixedly installed at the lower sides of both sides of the pile body, multiple reinforcing columns fixedly installed at the front and rear sides of the pile body, an anchor hole opened at the upper part of the pile body, multiple retaining plates movably connected between two pile bodies, a main frame tube provided inside the pile body, an extended frame provided inside the tensile seats, and a secondary frame tube provided inside the reinforcing columns, wherein the main frame tube, the secondary frame tube, and the extended frame are fixedly connected to each other.

[0007] As a further preferred embodiment of this utility model, the pile body, tensile seat, and reinforcing column are integrally formed by pouring concrete into the sub-frame tube, the outer frame, and the sub-frame tube.

[0008] As a further preferred embodiment of this utility model, multiple reinforcing columns are equidistantly arranged on the front or rear side of the pile body. Multiple integrally cast reinforcing columns are arranged on the front and rear sides of the pile body to form an integral structure with the pile body, increasing the moment of inertia of the cross section, dispersing the compressive stress generated by external loads, and their distribution pattern can constrain the lateral deformation of the pile body and improve the compressive strength of the pile body.

[0009] As a further preferred embodiment of this utility model, a plurality of inserts are fixedly installed on one side of the retaining plate, and two inserts form a group.

[0010] As a further preferred embodiment of this utility model, two support blocks are fixedly installed on one side of the retaining plate, and the two support blocks are respectively close to one of the insert blocks. The insert blocks are inserted between two reinforcing columns, and one side of the support block abuts against one side of the pile body. The retaining plate can be quickly assembled between two pile bodies through the two sets of insert blocks, and the soil retention capacity can be improved by setting the support blocks.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, multiple integrally cast reinforcing columns are set on the front and rear sides of the pile body to form an integral structure with the pile body, which increases the moment of inertia of the cross section, disperses the compressive stress and constrains the lateral deformation, thereby improving the compressive strength. At the same time, the retaining plate is quickly assembled by inserting blocks and reinforcing columns and supporting blocks abutting against the pile body, thereby improving the soil retaining capacity.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-3 As shown, the present invention provides an anti-slide pile structure for rock and soil slope protection, including a pile body 1, tensile seats 2 fixedly installed on both sides of the pile body 1, multiple reinforcing columns 3 fixedly installed on the front and rear sides of the pile body 1, an anchor hole 4 opened in the upper part of the pile body 1, multiple retaining plates 5 movably connected between two pile bodies 1, a main frame tube 6 is also provided inside the pile body 1, an outer frame 8 is also provided inside the tensile seats 2, and a secondary frame tube 7 is also provided inside the reinforcing columns 3, and the main frame tube 6, the secondary frame tube 7, and the outer frame 8 are fixedly connected to each other.

[0019] like Figures 1-2 As shown, the pile body 1, tensile seat 2, and reinforcing column 3 are integrally formed by pouring concrete into the secondary frame tube 7, the outer frame 8, and the secondary frame tube 7. Multiple reinforcing columns 3 are equidistantly arranged on the front or rear side of the pile body 1. Multiple integrally cast reinforcing columns 3 are set on the front and rear side of the pile body 1 to form an integral structure with the pile body 1, increasing the moment of inertia of the cross section, dispersing the compressive stress generated by the external load, and their distribution pattern can constrain the lateral deformation of the pile body 1 and improve the compressive strength of the pile body 1.

[0020] like Figure 3 As shown, multiple inserts 9 are fixedly installed on one side of the retaining plate 5, and two inserts 9 form a group. Two support blocks 10 are fixedly installed on one side of the retaining plate 5, and the two support blocks 10 are respectively close to one of the inserts 9. The inserts 9 are inserted between two reinforcing columns 3, and one side of the support block 10 abuts against one side of the pile body 1. The retaining plate 5 can be quickly assembled between two pile bodies 1 through the two groups of inserts 9, and the soil retention capacity can be improved by setting the support blocks 10.

[0021] It should be noted that this utility model is an anti-slide pile structure for rock and soil slope protection. The tensile seats 2 on both sides of the pile body 1 are fixedly connected to the main frame tube 6 inside the pile body 1 through the internal extended frame 8, which can enhance the pull-out resistance of the bottom of the pile body 1. In addition, multiple reinforcing columns 3 are equidistantly arranged on the front and rear sides of the pile body 1 and are fixedly connected to the main frame tube 6 through the internal secondary frame tube 7. The pile body 1, tensile seats 2, and reinforcing columns 3 are integrally formed by pouring concrete from the secondary frame tube 7, the extended frame 8, etc., to form an integral structure. The reinforcing columns 3 increase the size of the pile body 1. The moment of inertia of the cross section disperses the compressive stress generated by the external load. Its distribution pattern constrains the lateral deformation of the pile body 1 and improves the compressive strength. When the retaining plate 5 is set between the two pile bodies 1, the insert 9 on one side of the retaining plate 5 is inserted between the two reinforcing columns 3, and the support block 10 abuts against one side of the pile body 1. The quick assembly is achieved by the cooperation of the insert 9 with the reinforcing column 3 and the tight abutment of the support block 10, which improves the soil retention capacity. In addition, a shim is also set on the side of the support block 10 that contacts the pile body 1, so that the pile body 1 can provide support force to the retaining plate 5 through the support block 10.
