Abstract

The invention relates to a construction process for a bored pile close to a flood wall through a riprap layer. A bent frame is lapped close to the side of a flood wall and erected above the flood wall to form a drilling platform, and a pile driver is placed on the bent frame for construction; and the concrete process flow is as follows: firstly, obstacle clearing and outer shielding canister burying; secondly, inner shielding canister burying; thirdly, drilling machine replacing for continuous drilling; fourthly, hole cleaning, fifthly, reinforcement cage hanging; sixthly, underwater concreting; and lastly, inner shielding canister pulling. The construction process solves the problems of obstacle clearing, hole forming and stability of hole wall of the bored pile in the thick riprap layer by combining the inner sleeve and the outer sleeve; the geotextile is arranged on the inner side of the sleeve of the full-rotating drilling machine for recycling the outer shielding canister, therefore, the construction process has a certain economical efficiency, and the underwater concreting is carried out when the Huangpu River is in high water level to ensure the slurry return for the bored pile close to the flood wall by the Huangpu River and to ensure the smooth construction of the pile foundation and the quality of the pile body of the bored pile close to the flood wall by the Huangpu River.

Description

technical field [0001] The invention relates to a construction technology of bored cast-in-place piles, in particular to a construction technology of bored cast-in-situ piles near a flood control wall and formed holes passing through a riprap layer. Background technique [0002] The existing project starts from Xinkai River in the north, Dongmen Road in the south, Zhongshan East Road in the west, and Huangpu River in the east. The shoreline is 630m long and covers an area of ​​30,400m 2 . The hydrophilic platform and the floating pier for visiting the Pujiang River are close to the Huangpu River. The onshore pile foundation of the hydrophilic platform is inside the existing flood control wall, with a pile diameter of Φ800mm and an effective pile length of 39m. The net distance between some pile foundations and the existing flood control wall is only 10cm , and need to pass through the riprap foundation of the flood control wall. When the riverside side of the project is re...
