Mucky soil resistance-increasing steel pipe pile foundation reinforcing structure and construction method

Abstract

The invention discloses a mucky soil resistance-increasing steel pipe pile foundation reinforcing structure. The mucky soil resistance-increasing steel pipe pile foundation reinforcing structure comprises mucky soil, a plurality of resistance increasing type steel pipe piles with the tops higher than the top of the mucky soil are vertically arranged in the mucky soil, a gravel layer, a plain soillayer and a concrete cushion layer are sequentially arranged on the upper surfaces of the mucky soil from bottom to top, and a reinforcing mesh is arranged at the bottom of the plain soil layer; and the invention further discloses a construction method of the mucky soil resistance-increasing steel pipe pile foundation reinforcing structure. The mucky soil resistance-increasing steel pipe pile foundation reinforcing structure and the construction method mainly aim at solving the problem that silt soil in some foundation pits is too much and deep and is not easy to construct, foundation reinforcement can be rapidly achieved through the implementation of the mucky soil resistance-increasing steel pipe pile foundation reinforcing structure and the construction method, large mechanical equipment does not need to be adopted, and the construction period and the construction cost both can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a foundation reinforcement structure and a construction method of muddy soil resistance-increasing steel pipe piles. Background technique [0002] During foundation pit construction, it is often encountered that the foundation pit is located in an area where the original pond or the groundwater level has been high for a long time, resulting in a lot of silt and soil in the foundation pit. Currently, the commonly used construction techniques are riprap and cement-soil mixing piles, etc. , can solve the problem of foundation pit construction to a certain extent. However, for the deep silt soil, it is difficult to squeeze silt by riprap, and the project cost cannot be controlled, while the cost of cement mixing piles is high, and due to site constraints, it is generally difficult for mixing pile mechanical equipment to enter the site . Therefore, for the ...
