Pipe gallery mold

Abstract

The invention belongs to the technical field of moulds, and specifically discloses a pipe gallery mould, which includes an inner mold and an outer mold, the outer mold includes a bottom mold, two opposite end molds and two opposite side molds, the inner mold The two ends of the mold are respectively connected with two opposite end forms, the side forms and the bottom form include connecting brackets and concrete prefabricated parts, the two opposite end forms are connected through the connecting brackets, and the concrete prefabricated The component is arranged in the gap formed by the connecting bracket and the end form, and the concrete prefabricated part is connected with the end form and the connecting support and spliced ​​tightly. After the demoulding, the prefabricated part is closely attached to the pipe gallery, which strengthens the side wall and bottom of the pipe gallery, reduces the use of structural steel bars, reduces the amount of concrete used in the pouring process of the pipe gallery, and reduces the cast-in-place concrete in the pipe gallery The volume improves the heat dissipation effect inside the concrete and prevents cracking. At the same time, the side wall and bottom of the pipe gallery do not need to be demoulded, which reduces the difficulty of demoulding and speeds up the construction process.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a pipe gallery mould. Background technique [0002] The use of the comprehensive pipe gallery intensively accommodates the pipelines in the comprehensive pipe gallery, which not only beautifies the environment, but also avoids the trouble of repeated excavation of the road surface due to burying or repairing pipelines. At present, the construction of comprehensive pipe gallery usually adopts the following two methods: one is on-site cast-in-place, and the other is factory prefabrication; all the work of the on-site cast-in-place underground pipe gallery is completed on site, so the side walls and roof must be equipped with formwork, which not only causes A large amount of formwork is wasted, and the construction period is long. In order to ensure the operation space of the construction, the amount of earthwork excavation is large, and the amount of backfill is also lar...

At present, the construction of comprehensive pipe gallery usually adopts the following two methods: one is on-site cast-in-place, and the other is factory prefabrication; all the work of the on-site cast-in-place underground pipe gallery is completed on site, so the side walls and roof must be equipped with formwork, which not only causes A large amount of formwork is wasted, and the construction period is long. In order to ensure the operation space of the construction, the amount of earthwork excavation is large, and the amount of backfill is also large, which increases the production cost and prolongs the construction period. All raw materials are transported to the site in bulk. , the on-site production will also cause damage and pollution to the surrounding ecological environment. The method of on-site pouring requires high manual vibration. If the vibration is not solid, there is a greater possibility of microcracks in the later stage of the pipe gallery, which will leave hidden dangers of water leakage.

The prefabricated pipe gallery is formed by splicing multiple prefabricated pipe sections on site, and one-time pouring molds are mostly used. However, the above pouring molds need to be built repeatedly, which is time-consuming and material-consuming, and the demoulding steps of the pouring molds are very cumbersome, which is not conducive to mass production. pouring
