Method for forming trapezoidal drainage ditches by means of pouring on basis of adjustable groove forming molds

Abstract

The invention belongs to the field of mold erecting and pouring technologies for drainage ditches for airport construction engineering, and discloses a method for forming trapezoidal drainage ditches by means of pouring on the basis of adjustable groove forming molds. The method has the advantages that by the aid of the method, the problems of incapability of recycling mold erecting devices and the like, long construction periods, difficulty in guaranteeing the construction quality of existing drainage ditches and the like due to variable sections of most existing grooves and structural limitation of the existing mold erecting devices and existing excavator bucket devices when the existing grooves of the existing ditches are constructed can be solved; grooves are subjected to one-step excavation and one-step mold erecting pouring by the aid of adjustable excavator bucket devices and the groove forming molds, the adjustable groove forming molds comprise mold erecting supports, wood mold plates and hollow steel pipes with rectangular sections, and every two corresponding wood mold plates cling to the inner side wall of the corresponding groove of the corresponding drainage ditch, can be supported by the corresponding mold erecting supports and can be tensioned by rotary components; slope ratios of the mold erecting supports of the adjustable groove forming molds can be adjusted according to change of slope ratios of the grooves, the molds only need to be simply adjusted without mold processing, accordingly, the molds are high in utilization rate as compared with the traditional integral welded mold erecting supports, and adjustment procedures are simple.

Description

technical field [0001] The invention belongs to the technical field of formwork and pouring of drainage ditches in airport construction engineering, and in particular relates to a trapezoidal drainage ditch pouring and forming method based on an adjustable groove forming mold. Background technique [0002] Due to the large and relatively flat surface of the airport site, the different land conditions, the lack of natural waterways and side ditches, and the large accumulation of outflow water at the end of the construction area, the drainage area is relatively large, and the airport drainage has more complex requirements. Atmospheric precipitation formed by rain and snow is relatively concentrated. Small precipitation will cause ground water to affect normal traffic, and large precipitation will wash away road shoulders, roadbeds and slopes. Therefore, for airport works, extensive drainage systems are required. [0003] At present, the cross-sectional form of the airport dra...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to solve the problem that during the construction of the drainage ditch, since most of the trenches have variable cross-sections, due to the structural limitations of the existing vertical formwork and bucket devices, the vertical formwork and other devices cannot be reused, the construction period is long, and the construction quality of the drainage ditch is poor. Difficult to guarantee and other problems, and then provides a trapezoidal drainage ditch pouring molding method based on an adjustable groove forming mold
