Drainage trench structure for municipal engineering

Abstract

The present invention discloses a drainage trench structure for municipal engineering. The drainage trench structure comprises a drainage trench main body, a well chamber is vertically arranged at themiddle portion of the drainage trench main body, the well chamber is inlaid in a road base, the top portion of the road base is connected with a pavement, inclination surfaces are symmetrically arranged on the pavement, a cover plate support seat is horizontally fixed between the inclination surfaces, a sediment filter screen is vertically arranged between one end of the cover plate support seatand the bottom ends of the inclination surfaces, clamping posts are fixed at the other end of the cover plate seat, a tree blade filter screen is transversely arranged at the bottom ends of the clamping posts, a stainless metal cover plates is correspondingly arranged above the tree blade filter screen, and spacing grooves corresponding to the clamping posts are symmetrically arranged at the bottom portion of the stainless metal cover plate. The drainage trench structure for municipal engineering is provided with the stainless metal cover plate and the well chamber, the inner wall of the wellchamber is made of light metal sheet materials, the port at the top portion of the well chamber is covered by employing the stainless metal cover plate, and the drainage trench structure for municipalengineering replaces traditional mortar concrete construction to avoid the phenomena of easy frost crack of a drainage trench and the coarse inner wall and is long in service life.

Description

technical field [0001] The invention relates to the technical field of municipal engineering equipment, in particular to a drainage ditch structure for municipal engineering. Background technique [0002] The drainage ditch is a ditch that discharges the accumulated water near the side ditch, intercepting ditch, and roadbed into the natural river ditch at the bridge or culvert. The traditional cast-in-place concrete drainage ditch has a rectangular cross-section. From a mechanical point of view, the surface of the material has strong viscous force, and the places with angles are easy to accumulate sediment and garbage. The application fields of drainage ditches include public areas, parking lots, gardens and landscape design. The existing mortar concrete drainage ditches are prone to freezing and cracking in winter, the inner walls are rough, the water flow is slow, and sediment and garbage are easy to accumulate. In addition, most of the drainage ditches are mixed on site ...

AI Technical Summary

Problems solved by technology

The application fields of drainage ditches include public areas, parking lots, gardens and landscape design. The existing mortar concrete drainage ditches are prone to freezing and cracking in winter, the inner wall is rough, the water flow is slow, and sediment and garbage are easy to accumulate, which produces peculiar smell and affects drainage performance.

In addition, most of the drainage ditches are mixed on site and built manually, and the drainage performance is easily affected by the construction. After the masonry is completed, it needs curing time, and there is a phenomenon that the composite material is damaged, causing safety problems, and the dynamic load capacity of the artificially built drainage ditches is relatively low. Weak, easy to break due to uneven force, no design and calculation, poor water collection performance, due to the large number of construction workers, the surface is prone to unevenness, the lines are not neat, and frequent maintenance is required according to the flow of vehicles or people
