Gap type water draining pipe mold and forming method

Abstract

The invention discloses a gap type water draining pipe mold and a forming method. The mold comprises a mold frame, a slotted pipe and an air bag; a material groove is formed in the mold frame, the slotted pipe can transversely penetrate the material groove to be arranged in the mold frame, an avoiding hole allowing the slotted pipe to penetrate is formed in the mold frame, a convex strip used forforming a water draining pipe gap is arranged at the bottom of the material groove, the air bag is arranged in the slotted pipe to be used for opening the slotted pipe in a supported manner so as to enable the slotted pipe to be expanded and fixed in the avoiding hole, and the air bag is provided with an inflation and deflation structure. During mold filling, the opened slotted pipe gap and the convex strip are oppositely arranged so as to enable the convex strip to block the gap of the slotted pipe, and a gap type water draining pipe die cavity is defined by the material groove, the convex strip and the slotted pipe.

Description

technical field [0001] The invention relates to a forming mold and a forming method for a slot type drainage pipe. Background technique [0002] Chinese patent document CN106671248A discloses a construction method of a subgrade central slit type drainage ditch, which is characterized in that: S1: Cut the PVC pipe used as the inner film along the direction of the busbar to form a slit, and insert a support part into the PVC pipe, the support part Open the gap of the PVC pipe; S2: Pour concrete into the mold so that the concrete completely fills the cavity of the mold and reaches the height of the prefabricated part; S3: Remove the supporting part from the openings on both sides of the PVC pipe after the concrete has finally set. The inner wall loses its support and is rolled up due to its own elasticity, and the gap is gradually closed, so that the PVC pipe and the concrete are automatically separated; S4: Wait for the final setting of the concrete, and the prefabricated part...

AI Technical Summary

Problems solved by technology

The support part specifically includes a support plate and a longitudinal wood for stretching the PVC pipe, and forms the gap of the drainage ditch through two steel plates and channel steel. The mold loading operation of the support part and the gap forming structure of the above structure is very troublesome, and the gap forming Setting the structure above is not conducive to concrete pouring. In addition, the PVC pipe is stretched through the support board and the longitudinal wood. Since the support board and the longitudinal wood do not have great elasticity, the PVC pipe is likely to move during the pouring process, which cannot be reliable support
