BACKGROUND

[0002] At present, under the reciprocating action of seismic load, the foundation is prone to liquefaction, which causes the loss of foundation bearing capacity, and the infrastructure such as houses, bridges and roads is inevitably damaged. At present, the common seismic liquefaction treatment methods include excavation and replacement method, dynamic compaction method, composite foundation, drainage consolidation method, etc.

[0003] Among them, the composite foundation technology as a commonly used foundation reinforcement form has the technical advantages of good integrity, high bearing capacity, small and uniform settlement, etc., and is widely used in engineering construction. However, the application shows that for the case of high seismic intensity, the semi-rigid pile composite foundation is prone to breakage, shear and other engineering problems under the action of horizontal shear of seismic waves, so that the composite foundation loses bearing capacity and cannot be restored. For the gravel and other bulk piles, due to their good drainage performance, they can accelerate the dissipation of excess pore water pressure and reduce foundation liquefaction, but they are difficult to obtain and have high cost. Therefore, seeking a new type of composite foundation with good drainage performance, easy material procurement, convenient construction, capable of bearing large vertical load, resisting shear action of seismic waves and restoring original state after earthquake is a core problem to be considered for foundation reinforcement in seismic liquefaction area.

This kind of composite foundation can realize certain drainage performance and has good bearing capacity, but has the characteristics of difficult deformation recovery in seismic liquefaction treatment, and has great engineering construction difficulty and pile body forming difficulty.

SPECIFIC IMPLEMENTATION METHOD

[0041] It should be noted that the following detailed description is exemplary and is intended to provide further description of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0042] The term "connected", "connected", and the like in the present application should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection, it can be direct connection, or indirect connection through intermediate medium, it can be internal connection of two elements, or interaction relationship of two elements, and those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific situation.

[0043] As introduced in the background, there are deficiencies in the prior art, in order to solve the above technical problems, the present application provides a waste tire reinforced water permeable concrete pile structure which can reduce shock and pressure.

[0044] Example 1

[0045] The embodiment of the present application provides a waste tire reinforced water permeable concrete pile structure which can reduce shock and pressure, the structure mainly comprises a pile body structure formed by vertically connecting a plurality of water permeable concrete columns 1, a compressible rubber block 4 with a water permeable hole and a spherical hinge 10 is placed in the middle of the adjacent upper and lower two layers of water permeable concrete columns 1, and is fixed by epoxy resin adhesive, and a ring-shaped framework formed by non-woven fabric 5 and waste tire is arranged outside the edge of the pile body; in the present application, the pile body structure adopts a new type of pile body structure with compressible rubber block containing water permeable hole and spherical hinge installed between adjacent water permeable concrete columns, which has the technical advantages of easy material selection, simple pile body forming and convenient construction, the new type of pile body structure can bear larger seismic shear wave and can restore to original state after earthquake, and also has good drainage performance, accelerates the dissipation of excess pore water pressure, and avoids the effect of foundation liquefaction; at the same time, the present application sets a ring-shaped net framework structure outside the pile body, the ring-shaped net framework structure adopts waste tire strip with high tensile strength and high elasticity, which can improve the shear and bending resistance of the new type of pile body, and the waste tire contains steel wire inside, which has small creep and can reduce local deformation of the pile body during operation service period, so that the bearing capacity and stability of the foundation are significantly improved. Through the combined action of the water permeable concrete column, the ring-shaped net framework structure and the compressible rubber block containing the water permeable hole and the spherical hinge, the pile body can remain stable when the seismic load is small, the pile body can be prevented from breaking when the seismic load is large, and the pile body can quickly return to the original state after the seismic load disappears, so as to ensure the comprehensive application effect of "small earthquake does not move, large earthquake does not fall, and self-repair after earthquake".

[0046] In the embodiment of the present application, the waste tire strip is cut from the waste tire with the tire wall removed along the crown pattern, the tire strip is not less than 1.5 cm in 2 / 3 thickness, the peak tensile strength of the 6 cm wide strip is not less than 15 kN, the ultimate load elongation is not more than 20%, and the tire strip width is not less than 4 cm. The standards are adopted to ensure the integrity of the waste tire and the uniformity of the specifications, facilitate the tire selection and quality control. Without the standards, the waste tires are various in type, size and quality, and the mesh skeleton structure further processed therefrom has more potential weak points, which inevitably causes problems such as excessive deformation and fracture when subjected to a large load, affecting the quality of engineering construction and the seismic effect.

[0047] In the embodiment of the present application, the mesh skeleton structure is formed by the vertical intersection of a plurality of transverse tire strips 3 and longitudinal tire strips 2, and the vertical intersection position is fixed together by high-strength rubber special adhesive glue combined with pre-tightening bolts 7 and square steel plates 8.

[0048] The diameter of the pre-tightening bolt 7 is not less than 0.6 cm, and the length is not less than 3 cm. The thickness of the square steel plate 8 is not less than 0.3 cm, and the length and width are 4 cm x 4 cm. The parameter requirements of the pre-tightening bolt 7 and the square steel plate 8 are used to ensure the connection stiffness of the waste tire. If the standards are lower, the shear capacity of the connection bolt cannot be guaranteed. If the standards are higher, the economy is insufficient. After the pre-tightening bolt 7 and the square steel plate 8 are fixed, corrosion protection treatment should be performed, such as spraying corrosion-resistant paint. Compared with the geogrid, the grid mesh skeleton made of tires can reduce the manufacturing cost and has higher tensile and elastic properties. As a ring-shaped skeleton, it can protect the structure of the permeable concrete pile and improve the lateral stability and shear capacity of the permeable concrete pile.

[0049] In the embodiment of the present application, after the tire mesh skeleton structure is formed, the row buckle connecting piece is installed and fixed along the axial direction of the pile body to form a ring-shaped skeleton structure. The row buckle connecting piece is arranged to simplify the construction process and reduce the construction difficulty.

[0050] In the embodiment of the present application, along the pile body direction, the center distance between adjacent transverse tire strips 3 is 15-20 cm, and the center distance between adjacent two longitudinal tire strips 2 is 20-25 cm. The parameter requirements can ensure that the tire ring-shaped skeleton structure has optimal reinforcement performance, provides optimal friction resistance and bending resistance, and improves the stability and foundation bearing capacity of the new pile body. If the distance is less than the standard, the complexity of the processing procedure is obviously increased. If the distance is higher than the standard, the wrapping capacity of the mesh skeleton structure is reduced.

[0051] In the embodiment of the present application, the pile body is wrapped with a layer of non-woven fabric 5, the non-woven fabric 5 is made of water-permeable and mud-impermeable material, the tensile strength is not less than 0.8 MPa, and the annular wrapping shape is formed by using a coating adhesive bonding method, and the overlapping length of the bonding part is not less than 25 cm. The standard is used to ensure that the non-woven fabric 5 wrapped around the water-permeable concrete column can ensure the long-term water permeability of the pile body, prevent the soil from blocking the concrete hole pile body, and improve the consolidation efficiency and anti-seismic pressure relief capacity of the foundation. The non-woven fabric 5 is bonded inside the vertical tire strip 2 by applying 401 instant dry adhesive to form a composite tire packaging body.

[0052] In the embodiment of the present application, the compressible rubber block 4 of the water-permeable hole and the spherical hinge 10 is placed in the middle of the adjacent upper and lower two layers of water-permeable concrete columns 1, and is fixed by epoxy resin adhesive. The compressible rubber block needs to be drilled, the hole diameter is 5-10 mm, and the drainage performance of the rubber block 11 is ensured. The bottom of the rubber block 11 needs to be excavated, and the spherical hinge 10 is installed in the hole for fixation, and the swing angle is not less than 10 degrees. In this way, by connecting adjacent water-permeable concrete columns 1 through the compressible rubber block 4, a larger seismic shear wave effect can be borne, and the body is prevented from being cut or broken. When the seismic load is over, the pile body can automatically restore to its original state.

[0053] It should be noted that the water-permeable concrete column 1 provided by the embodiment of the present application is prepared by using coarse aggregate, cement and water reducing agent.

[0054] It should be noted that the water-permeable concrete can also be replaced by other water-permeable porous materials, which also has obvious shock absorption and pressure relief effect, speeds up the dissipation of excess pore water pressure in the foundation soil, improves the consolidation rate, and avoids foundation liquefaction.

[0055] The waste tire reinforced water-permeable concrete pile structure provided in the embodiment can realize the stability of the pile body when the seismic load is small, avoid the breakage of the pile body when the seismic load is large, and restore to the original state after the seismic load disappears, thereby ensuring the comprehensive application effect of "no movement under small earthquake, no falling under large earthquake, and self-repairing after earthquake".
