Problems solved by technology

The existing seawalls have low ability to prevent floods and tides. Since the overall embankment body is mainly composed of mixed soil, the overall seawall lacks stability. This status cannot meet flood and tide protection standards. When encountering strong typhoons and storm tides will be defenseless

Embodiment Construction

[0043] as table 1 to Figure 7 As shown, a construction method applied to foundation reinforcement in seawall flood protection includes the following steps:

[0044] (1) Seawall foundation simulation:

[0045] Draw the structural drawings of the seawall according to the actual shape of the seawall under construction, reduce the seawall to a scale of 1:200 in the drawings, and use the drawings as a reference to artificially build a simulation test area:

[0046] In the process of constructing the simulated test area, the test area is first constructed according to the drawings, and then the base of the seawall is excavated, and the base of the seawall is laid in the test area, and the foundation is compacted to ensure that the foundation of the test area is in line with the seawall. The foundation structure is similar; after the laying is completed, water is injected into the test area to the design depth, which is consistent with the water depth of the seawall.

Abstract

The invention discloses a construction method for foundation stabilization of seawall protection in a flood season. The construction method for foundation stabilization of seawall protection in the flood season includes the following steps of (1) simulation of the seawall foundation; (2) testing of mixing pile construction; (3) determination of the mixing pile location; (4) layout of rails; (5) placement of a pile driver; (6) premixing and subsidence; (7) mixing and lifting of sprayed concrete; (8) repeated mixing and subsidence; (9) repeated mixing and lifting; and (10) completion of pile forming. According to the construction method for foundation stabilization of seawall protection in the flood season, simulation of seawall foundation is conduced firstly, simulated test site is built, the mixing pile construction process is simulated in the test site, and mixing pile construction parameters is reasonably screened by measuring relative indexes of the mixing pile. Construction work is conducted based on the mixing pile parameters, and after construction, the pile has high loading capacity, excellent foundation stabilization effect, high rain resistance and flood control capacity, and has great significance on seawall protection work in the flood season.

Description

technical field [0001] The invention relates to a foundation flood protection method, in particular to a foundation reinforcement construction method applied to seawall flood protection. Background technique [0002] In order to prevent and control potential rainstorms, floods and other disasters, in the event of floods and other emergencies, we can quickly and effectively respond to emergencies, minimize casualties and property losses, and often carry out flood protection at river banks, docks and other locations Construction, establish a good and complete flood protection project. The existing seawalls have low ability to prevent floods and tides. Since the overall embankment body is mainly composed of mixed soil, the overall seawall lacks stability. This status cannot meet flood and tide protection standards. When encountering strong typhoons and storm tides There will be no resistance. [0003] The mixing pile method is a method of composite foundation treatment, which...
