Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0026] refer to figure 1 with figure 2 , the preferred embodiment of the present invention provides a kind of reverse underground diaphragm wall construction method, comprises the following steps:

[0027] S1: The upper outer wall 10 of the ground connecting wall is constructed on the diaphragm wall soil by using the manual excavation reverse method.

[0028] S2: Use the grooving machine 40 to form a groove on the layer 30 at the upper outer wall 10 of the ground connecting wall to form a groove for forming the lower wall of the ground connecting wall, and the groove is located on the inner side of the upper outer wall 10 of the ground connecting wall .

[0029] S3: The lower part of the ground connection wall is formed by casting in the trench....

Abstract

The invention discloses a reverse underground continuous wall construction method which includes the steps: constructing an upper outer wall body of a concrete diaphragm wall on a continuous wall soilbody by a manual excavation reverse construction method; forming a groove for forming a lower wall body of the concrete diaphragm wall at the upper outer wall body of the concrete diaphragm wall by agrooving machine, and enabling the groove to be positioned on the inner side of the upper outer wall body of the concrete diaphragm wall; pouring concrete into the groove to form the lower wall bodyof the concrete diaphragm wall; pouring concrete into a notch formed by the lower wall body of the concrete diaphragm wall and the upper outer wall body of the concrete diaphragm wall to form an upperinner wall body of the concrete diaphragm wall, and enabling the upper outer wall body of the concrete diaphragm wall, the upper inner wall body of the concrete diaphragm wall and the lower wall bodyof the concrete diaphragm wall to form an underground continuous wall to be constructed. According to the reverse underground continuous wall construction method, by the aid of a 'manual reverse construction + machinery grooving' mode, safety of excavation construction is ensured, construction schedule requirements are ensured, water leakage cannot be easily generated, later foundation pit excavation construction is greatly facilitated.

Description

technical field [0001] The invention relates to the field of construction of underground diaphragm walls, in particular to a method for reverse construction of an underground diaphragm wall. Background technique [0002] With the vigorous development of urban construction in our country, a large number of underground projects have been developed. In the construction technology of underground projects, underground diaphragm walls are widely used as the main body of building foundation pit enclosure such as retaining soil, anti-seepage and load-bearing of permanent main structure of high-rise buildings. During construction, the underground diaphragm wall cannot be constructed normally due to the presence of pipelines above the foundation pit or other buildings around the foundation pit. The reverse construction of the underground diaphragm wall is a new technology based on this situation. [0003] During the traditional upside-down underground diaphragm wall construction, manu...
