Embodiment Construction

[0016] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0017] A construction method for inserting a steel column into a bored pile, comprising the following steps:

[0018] (1) Pile hole formation of cast-in-situ piles: do slope protection treatment to prevent the soil collapse at the upper end of the pile hole, and the pile driver will shape the pile hole and clean the pile hole;

[0019] (2) hoisting reinforcement cage 6;

[0020] (3) Pouring concrete 7;

[0021] (4) hoisting the steel protective pipe to protect the wall of the pile hole;

[0022] (5) Cleaning the pile holes: mainly to pump out the mud in the pile holes and the operator to enter the pile holes, clean up the pile head concrete and other sundries, and place the bottom fixer 8 of the steel column. The anchor bar 9 is welded und...

Abstract

The present invention relates to a construction method for inserting steel column in bored pile, comprising the following steps: (1) forming a pile hole of a bored pile; (2) hoisting a reinforcement cage; (3) pouring concretes; (4) hoisting a steel protection pipe; (5) cleaning the pile hole and placing a steel column bottom fixer; (6) hoisting a steel column, so as to complete the installation of the steel column; a top end of the hoisted reinforcement cage in the step (2) is coaxially and fixedly provided with a steel sleeve; the inner diameter of the steel sleeve is identical to the diameter of the pile hole; elevation at a top end of the steel sleeve is the same as the elevation at the top of the bored pile. The steps of construction technology of the present invention are simple; constructional time is shortened; working efficiency is improved; and constructional cost can be reduced effectively; and the present invention is a construction method for inserting steel column in bored pile with relatively high safety.

Description

technical field [0001] The invention belongs to the field of building construction, in particular to a construction method for inserting steel columns into bored piles. Background technique [0002] At present, more and more underground structures of civil and municipal buildings are constructed by the reverse method. In order to ensure the smooth progress of the construction and take into account the construction of the upper structure, the columns of the underground part generally adopt the form of steel columns. The design of the steel columns can be steel pipe columns or Steel lattice column, concrete poured into the steel pipe column, and concrete covered by the steel lattice column. In the construction requirements, the steel column should be inserted into the bored pile below it, and the insertion depth is about 2000mm. The construction of the underground structure can be started in accordance with the construction sequence of the reverse method: excavation → negative...
