Cast-in-place Concrete Drain Rail Sliding Formwork System and Construction Method

Abstract

The invention relates to a sliding-rail-type formwork system for a cast-in-place concrete drainage ditch, and a construction method thereof. The sliding-rail-type formwork system for the cast-in-placeconcrete drainage ditch is characterized in that a soil layer is internally provided with a drainage ditch foundation pit, cement soil piles, the drainage ditch, a sliding-rail-type formwork, formworks, reinforcing cover beams and the like. The construction method comprises the main construction steps that the cement soil pile is constructed; the foundation pit is excavated; unit-type steel platepiles are supported; the bottom of the foundation pit is constructed; rabbet press-connecting steel plate groove-type jacking pieces are mounted; the reinforcing cover beams are mounted; the outer side formworks are erected; a drainage ditch bottom plate is poured; a sliding rail is mounted; the sliding-rail-type formwork is mounted, the inner side formworks are erected; a shaped bracket is mounted; the side wall of the drainage ditch is poured; and the inner side formworks and the outer side formworks are hoisted for the next stage of construction. According to the sliding-rail-type formworksystem for the cast-in-place concrete drainage ditch, and the construction method thereof, construction is convenient, meanwhile, the construction efficiency is high, the formworks, the sliding-rail-type formwork and the sliding rail can be used repeatedly, sustainable utilization of resources can be achieved, and the good economic and technical benefits are achieved.

Description

technical field [0001] The invention relates to a cast-in-place road drainage ditch and a construction method, in particular to a cast-in-situ concrete drainage ditch rail sliding formwork system and a construction method. Background technique [0002] The strength and stability of subgrade pavement are closely related to water. There are many kinds of diseases on the subgrade and pavement, and there are many factors that cause the diseases, but the role of "water" is one of the main factors. Therefore, in the process of expressway construction, effective measures must be taken to drain water and ensure the smoothness of the expressway. Safety and stability, reducing water hazards to the road. [0003] The drainage ditch is required to be placed on a stable stratum or a compacted soil layer, and the design position needs to be combined with the direction of the water flow. The construction work area of ​​the drainage ditch that often occurs in construction is small, which ...

AI Technical Summary

Problems solved by technology

The drainage ditch that often occurs in construction has a small construction area, which undoubtedly brings a lot of difficulty to the formwork support. The traditional construction method needs to spend a lot of time on the process of formwork support and formwork fixing.
