Permeable concrete square pile

Abstract

The invention relates to a permeable concrete square pile. The permeable concrete square pile comprises a concrete pile body. An inner cavity extending in the length direction of the concrete pile body is formed in the concrete pile body. A convex rib and an inserting groove which are matched with each other are correspondingly formed in the two opposite side surfaces of the concrete pile body. A plurality of permeable holes communicating with the outside and the inner cavity are formed in each of the other two opposite side surfaces of the concrete pile body. When the permeable concrete square pile is installed, an adjacent square pile is inserted into the inserting groove of another square pile to be fixed through the convex rib, it is ensured that the entirety is not dislocated, the stability of the permeable concrete square pile is better, the square piles are easily connected mutually, the permeable function is achieved, a bunding guarding wall made by the square pile can make the river to exchange water with the soil on the bunding, and the ecological environment is protected.

Description

technical field [0001] The invention relates to a permeable concrete square pile, which belongs to the technical field of concrete piles. Background technique [0002] Large-scale underground buildings, quay walls of ports and revetments of rivers, etc. During construction, these buildings need to protect themselves or the foundations of surrounding buildings. The requirements for the embankment protection wall are: high rigidity wall, ecological environment and easy construction. Of course, under the premise of meeting the above conditions, the lower the cost, the better. [0003] There are three types of bank protection walls commonly used at present. The first type is to use multiple reinforced concrete circular piles combined with cement mixing piles and then insert the soil to form an enclosure wall. There are also multiple T-shaped piles or SMW construction methods. Cement mixing piles are inserted into the soil to form a retaining wall. Since reinforced concrete rou...

AI Technical Summary

Problems solved by technology

Since the reinforced concrete round piles, T-shaped piles and cement mixing piles produced by the SMW construction method are inserted into the soil, the maintenance wall formed after being inserted into the soil cannot meet the ecological and environmental protection requirements of the embankment protection wall

In addition, when the SMW construction method and bored piles are used to manufacture the retaining wall, cofferdam filling is required, and the cost is astonishing. However, T-shaped piles are limited by their shape, and their stability is not ideal when used for embankment protection. Therefore, a kind of Concrete pile with good water permeability and good fixation
