Problems solved by technology

The formwork of the underground comprehensive pipe gallery in the prior art includes the side wall formwork and the top wall formwork and the corner formwork connecting the side wall formwork and the top wall formwork. At present, there are three types of underground comprehensive pipe gallery formwork: shaped steel formwork, wooden formwork and platform formwork. The car model, the shaped steel model is too heavy, the transportation is inconvenient, and the crane is needed to cooperate, and the construction progress is slow; the turnover of the wooden model is small, the formwork occupies a lot, and the appearance and quality of the formed concrete are poor; the cost of the trolley is high, and the construction progress is slow

Abstract

The invention discloses an underground pipe gallery formwork. The underground pipe gallery formwork comprises side wall formworks, a top wall formwork and corner formworks used for connecting the sidewall formworks and the top wall formwork. The top wall formwork is composed of a plurality of aluminum alloy formwork units. Each aluminum alloy formwork unit comprises a plurality of parallel aluminum alloy flat plates with the side edges being detachably connected, and a transverse top formwork keel which is detachably connected with the ends of the multiple aluminum alloy flat plates. Supporting heads with the top faces supporting a pipe gallery reinforced concrete top plate are formed in gaps of every two adjacent aluminum alloy formwork units. The supporting heads and the two adjacent top formwork keels are detachably connected, and the top formwork keels and the corner formworks are also detachably connected. The supporting heads are fixedly connected with stand columns supported onto the ground. The other end, far away from the corresponding top formwork keel, of each aluminum alloy formwork unit is detachably connected with the top formwork keel of another adjacent aluminum alloy formwork unit. The underground pipe gallery formwork can be conveyed and transported conveniently, and the turnover frequency of the formwork is high.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to an underground comprehensive pipe gallery template. Background technique [0002] Underground comprehensive pipe gallery is becoming more and more popular as a tunnel structure that aggregates various urban pipes such as electric power, communication, gas, heating, water supply and drainage. At present, the underground comprehensive pipe gallery generally adopts open-cut trenches, then builds formwork, pours reinforced concrete, and removes the formwork after the concrete strength of the roof basically meets the design requirements, such as reaching more than 80% of the design requirements, generally after concrete pouring It takes 4 or 5 days to remove the formwork. The formwork of the underground comprehensive pipe gallery in the prior art includes the side wall formwork and the top wall formwork and the corner formwork connecting the side wall formwork ...
