Method for constructing roof drain through adopting geotechnical formwork technology

Abstract

The invention provides a method for constructing a roof drain through adopting a geotechnical formwork technology. The method comprises the steps of constructing the roof drain after raised curbs are installed, pre-baking a clay model and a concrete model in the position of the roof drain before a roadbase and a lower asphalt surface layer are constructed, manually digging a pre-baked formwork out after the lower asphalt surface layer is completely constructed, and constructing and reinforcing the roof drain; laying the bricks of the roof drain through adopting a three-one bricking method, i.e. one shovel of concrete, one brick and one compression; and reinforcing the roof drain through adopting a support fixing and seat suspending method. The method has a process of construction preparing, layered clay model baking, roadbase constructing, layered concrete model baking, lower road layer constructing, manual concrete model and clay model digging, roof drain constructing, lintel and rain grate installing, roof drain reinforcing, plastering and pointing and acceptance inspecting. Compared with a conventional technology, the method can be used for effectively overcoming the quality defects of uneven distances between the roof drain and the raised curbs, sedimentation, bumping in a car running process, abnormal sounds and the like, the working efficiency is increased, the construction period is shortened, and the material waste is reduced.

Description

technical field [0001] The invention relates to a construction method of a municipal road rainwater bucket, in particular to a construction method of a rainwater bucket using a geotechnical formwork technology, which is suitable for the construction of rainwater buckets on urban suburban roads or areas with low traffic pressure and not too tight construction period. Background technique [0002] The municipal road rainwater bucket project adopts hot-rolled integrally formed comb-shaped bridge expansion joints. The construction speed is slow, the flatness is poor, and settlement, water seepage, vehicle jumping and abnormal noise often occur. Jinan Urban Construction Group carried out technical research on the above problems, adjusted the construction technology, and summarized the method of constructing rainwater buckets by geotechnical formwork technology through on-site practice, and solved the common quality problems in the construction process of rainwater buckets. The ov...
