AI Technical Summary

Technical Problem

During the construction process of small aqueducts, the inner and outer formwork needs to be installed or disassembled one by one, resulting in slow construction speed and repeated disassembly and installation of the formwork, which has a large loss.

Method used

A U-shaped thin-wall aqueduct body casting groove machine is provided, including a base, a U-shaped inner mold, an inner mold sliding unit and two sets of outer molds. The height and position of the inner mold and the outer mold are adjusted by the hydraulic cylinder to achieve rapid movement and separation.

Benefits of technology

Through manual adjustment by workers, rapid movement and separation of U-shaped inner mold and outer mold is achieved, which improves the construction efficiency of the aqueduct and reduces equipment complexity and usage costs.

Abstract

The utility model discloses a U-shaped thin wall aqueduct body in-situ cast-in-place aqueduct making machine, which relates to the aqueduct construction field, and comprises a base, a U-shaped inner mould, an inner mould sliding unit and two groups of outer side moulds, the U-shaped inner mould is arranged above the base, N groups of inner mould supports and N supporting beams are arranged in the U-shaped inner mould, the supporting beams are arranged above the inner mould supports, and the outer side moulds are arranged on the base. The two sets of hydraulic cylinders are controlled to stretch synchronously, so that the U-shaped inner mold moves upwards and is separated from the groove body, the U-shaped inner mold is pushed by a worker to move, the U-shaped inner mold is rapidly moved to the next construction section, the outer side mold is detached and separated from the base, the worker can push the outer mold support to move, and the outer side mold and the groove body are rapidly separated. According to the aqueduct making machine, manual adjustment is mainly conducted through workers, the adjustment precision is controllable, no complex control system is arranged, the structure is simple, the use cost is low, and the construction efficiency of the aqueduct can be improved.
