Abstract

A job practice of which center island is done in sequence and partial skirts done inversely, comprising the following steps : set up exterior-protected construction, purlin and steel upright columns around the foundation ditch; dig on basin pattern for the first time to the depths to structural plane of purlin, earthwork are unified dig beneath the designed to the surrounding medium plate in the foundation ditch, pour the surrounding medium plate; dig for the second time with basin pattern downwards from the position of foundation ditch medium plate to the bottom of the designed foundation ditch, pour the center island plate; after the center island plate meets the maintenance time request of plate, construct in sequence to close the medium plate, setting fetching holes; then use medium plate for support system, construct criss-cross structural upper plate and plates in inverse zones. This construction method is convenient, save labor force and resources, improves the progress of the project, shorten the construction period.

Description

technical field

[0001] The invention relates to the construction technology of the semi-inverted construction method in the current construction, in particular to a construction method in which the central island is built along the side and the partial skirt is reversed. Background technique

[0002] The reverse method that emerged in the 1980s is to excavate a section of earthwork downward after the surrounding enclosure, that is, the underground diaphragm wall, and then use the false corbel method to pour the concrete structure of this section, and then proceed downwards sequentially. Construction method up to the bottom. In the top-down construction process, due to the gentle soil surface, the elevation of the soil surface under the structure is generally consistent with the bottom surface of the structural beams and slabs, that is, the construction of each layer of the structure using the soil membrane method does not require the support of bent frames.
