Construction method for nonstandard diaphragm wall

Abstract

The invention discloses a construction method for a nonstandard diaphragm wall and belongs to the technical field of the construction technology. Construction tools are improved, and the method includes excavating a guide wall groove, producing a guide wall, grooving through a hydraulic grab, placing an special-shaped locked port pipe, a reinforcement cage and the like, arranging a conduit to pour concrete, and repeating the operation to obtain the nonstandard diaphragm wall which is used for retaining soil and water and the like during building pit construction. The construction method is simple in process and convenient to operate, high in working efficiency and low in cost; the obtained nonstandard diaphragm wall is smooth in surface and good in water retaining effect; the used equipment is low in cost and little in improvement time; compared with the existing method in which the locked port pipe is reprocessed, the cost is reduced from one million to below 30 thousands, the time is reduced from one month to three days, and therefore the nonstandard diaphragm wall is low in construction cost, convenient to construct, attractive in appearance and easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an operation method and a construction method of a non-standard underground diaphragm wall with low construction cost and high efficiency. Background technique [0002] The width of the standard underground diaphragm wall is generally 600mm, 800mm, 1000mm and 1200mm. For the convenience of construction, there are locking pipes and groove forming machine grabs used in conjunction with them. The width of the locking pipe and groove forming machine grabs is also 600mm. , 800mm, 1000mm and 1200mm sizes, so the construction is convenient. In recent years, due to the consideration of energy saving in engineering projects, more and more non-standard continuous walls have been designed by the Design Institute, and non-standard underground continuous walls such as 700mm and 900mm have appeared, making the original standard hydraulic grooving machine bucket bo...

Problems solved by technology

In recent years, due to the consideration of energy saving in engineering projects, more and more non-standard continuous walls have been designed by the Design Institute, and non-standard underground continuous walls such as 700mm and 900mm have appeared, making the original standard hydraulic grooving machine bucket body , Bucket head and locking pipe cannot be used. There is no report on the construction method of the more convenient non-standard underground diaphragm wall. Generally, non-standard locking pipes and hydraulic grooving machine grabs are processed separately, and a set of locking The processing of tubes costs 800,000-1.2 million yuan, which will not only increase the cost, but also bring more idle
