Embodiment Construction

[0010] Below, the present invention will be further described in conjunction with specific modes:

[0011] A method for sealing and dismantling basement enclosure support body, it comprises:

[0012] Step 1: After the construction of the concrete support lower basement structure and the replacement of the support, the concrete non-main support at the intersection with the basement exterior wall is manually removed;

[0013] Step 2: Continue the construction of the basement structure. Part of the vertical structures located under the support, such as concrete columns and concrete walls, need to reserve concrete pouring holes and lapped steel bars at the corresponding positions of the previous construction floor, and remove and clean them in the support room. After the slag is completed, the structure will be supplemented, that is, the in-depth design of the remaining facility joints must be done in advance;

[0014] Step 3: After the construction of the basement structure, ...

Abstract

The invention relates to basement construction, in particular to a closed removing method for a basement enclosure supporting body. The closed removing method for the basement enclosure supporting body comprises the following steps: 1) after the construction of a concrete support lower part basement structure and the change of supports are completed, manually removing concrete non-main supports at positions intersected with the outer wall of a basement; 2) continuously conducting the construction of the basement structure, wherein concrete pouring and tamping spaces and overlapping reinforcements need to be reserved at corresponding positions for slab construction at an early stage for part of vertical structures such as concrete columns and concrete walls below the supports, and then structure supplementation is made after indoor demolition of the supports and debris removal are completed, i.e., deep design of reservation of construction joints needs to be conducted in advance; 3) after the construction of the basement structure is completed, removing concrete supports in a closed manner in the basement; 4) transporting waste reinforcements, debris and soil outside by using constructed basement lanes. closed removing method for the basement enclosure supporting body has the advantages that the protective shed does not need to be erected in large area, work such as the removal of the supports and the cleaning of wastes is simultaneously conducted with the construction of the upper structure, the construction period of a main line of a project is not occupied, the influence of support removal on the key line of structural construction is reduced, and the overall construction progress is accelerated.

Description

technical field [0001] The invention relates to basement construction, in particular to a method for dismantling basement enclosure supports. Background technique [0002] For ultra-deep basement pits with multi-channel reinforced concrete horizontal support, the current open-type dismantling support method is mostly used, and a protective shed is required. Garbage cleaning occupies the construction period of the main line of the project, which greatly restricts the construction period of the basement and the construction progress of the overall structure. Contents of the invention [0003] The present invention aims to solve the above-mentioned problems in the prior art, and provides a method for sealing and dismantling basement enclosure supports. The present invention does not require large-area protective sheds, supports removal, garbage cleaning and other work are carried out at the same time as the superstructure, does not occupy the construction period of the main l...
