Description

Technical Field

[0001] The utility model relates to the technical field of a prefabricated rainwater inlet concrete casting mould, in particular to a prefabricated mould for a road double-grate rainwater inlet. Background Art

[0002] Urban road rainwater inlets refer to water intake structures for collecting rainwater on the ground through drainage pipes. Rainwater on the street pavement first passes through the rainwater inlets and then flows into the drainage pipes through connecting pipes. The location of the rainwater inlets should ensure the rapid and effective collection of rainwater on the ground. Generally, they should be set up at intersections, at a certain distance from roadside ditches, and in low-lying places with road curbs to prevent rainwater from overflowing the road or causing water accumulation on the road and low-lying areas and hindering traffic. Rainwater inlets are usually cast on site. The traditional construction method is to use wooden formwork for construction, but the installation and disassembly of wooden formwork is slow, time-consuming and labor-intensive. At present, the prefabricated method is mostly used to make rainwater inlets first, and then the prefabricated rainwater inlets are directly installed during construction to improve construction efficiency. The prefabrication of rainwater inlets requires molds. Existing molds are mostly spliced ​​with wooden formworks, and most of them are single-grate structures, which cannot be applied to the production of double-grate rainwater inlets. The utility model patent with the authorization announcement number CN209775017U discloses a highly efficient prefabricated rainwater inlet mold, including an outer template and an inner template, both of which have channels running through the upper and lower end surfaces. The outer template is sleeved on the outer side of the inner template to form a sandwich between the inner template and is detachably suspended and fixed by a hanger to form the bottom plate and well wall of the prefabricated rainwater inlet after pouring; the connecting hole template is used to penetrate the pin shaft to hang the connecting hole template on the outer template or the inner template, so that the connecting hole template is arranged away from the two ends of the outer template and the inner template. In the interlayer, a tapered hole is formed on the wall of the prefabricated rainwater inlet after casting; the lintel template is detachably connected to the outer template and the inner template at a center position near the upper end surface of the outer template and the inner template by passing an axle pin, and is used to form a groove for placing the lintel on the top surface of the prefabricated rainwater inlet after the casting of the prefabricated rainwater inlet is completed; the hanging hole template is fixed to the outer template and the inner template in the interlayer, and is used to form a hanging hole after the casting of the prefabricated rainwater inlet is completed, which is convenient for lifting construction, but the mold is not easy to disassemble and the production cost is relatively high.
