Description

A processing device and construction method for a prefabricated pipe trench

technical field

The invention relates to the field of engineering construction, in particular to a processing device for prefabricated pipe trenches.

Background technique

The second-phase exhibition center project of Xi'an International Convention and Exhibition Center covers a total area of about 175,009 square meters and a total construction area of about 194,951 square meters. The exhibition center has a total of 6 exhibition halls, including 4 heavy-duty exhibition halls and 2 standard exhibition halls. Generally speaking, one of the most commonly used construction methods is the integrally poured one-piece trench structure, that is, the site needs to be excavated and the overall formwork pouring at the excavation site, but the traditional one-piece trench structure construction cycle During the pouring process, if the prepared concrete does not meet the strength, the entire pipe trench structure needs to be remade, wasting a lot of manpower and financial resources; If you do not pay attention, there will be some node honeycomb, pockmarked surface, etc. If you want to remedy this situation, a lot of manpower will be needed to check and repair; because the one-piece structure is too large, the required maintenance time will also be shortened. If the curing time is insufficient, it may cause the one-piece structure to crack or collapse.

Another method is the brick structure, but the overall structure is poor, easy to accumulate water and short life.

The entire Xi'an International Convention and Exhibition Center covers a large area and requires a short construction time. If the integrated pipe trench structure is used, it will face many risks.
