Problems solved by technology

This method causes a difference in elevation between the grille and the road surface, making it impossible to connect smoothly, causing uneven force on the grille when the vehicle rolls over it, poor driving comfort, and easily causing the grille to sink or bulge, resulting in damage to the road surface at the edge of the grille. When the vehicle is rolled over, the solder joints often fall off. When the vehicle passes, the grille cover and the base collide with each other, making a "bang bang bang bang" noise, which has long troubled the daily life of the surrounding residents.

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like figure 1 , shown in 2, the present invention discloses a kind of novel construction method of grid intercepting ditch, construction steps are as follows:

[0029] (1) Trench excavation, manual excavation with excavation machinery, so that the side wall of the trench side wall 10 and the top surface 11 are flat, and the distance b between the top surface 11 of the trench side wall and the road surface 20 is 100mm;

[0030] (2) Use expansion bolts 30 to install angle steel 40 or I-beam on the top surface 11 of the side wall of the intercepting ditch on both sides. In this embodiment, angle steel 40 of 75mm×75mm is used, and the distance between angle steel 40 is controlled between 605mm-610mm.

[0031] (3) Apply release agent evenly on t...

Abstract

The invention discloses a novel construction method of a grating intercepting ditch. The novel construction method mainly comprises the steps of digging a groove, installing a steel mold plate, spraying appropriate amount of emulsified asphalts, layering filling asphalts, removing the steel mold plate, placing a grating in an asphalt preassembling structure, and pressing the grating into a road surface to form one body. The construction method can reduce noise pollution and can reduce the possibility of road damage and road sinking and the maintaining operation is convenient.

Description

technical field [0001] The invention relates to a construction method of a ditch, in particular to a construction method of a grill intercepting ditch. Background technique [0002] Urban intercepting ditches are generally set on low-lying urban roads and on both sides of urban underpasses and tunnels to intercept rainwater at high altitudes and reduce drainage pressure in low-lying areas. The traditional construction method of the intercepting ditch is to install the steel base on the reinforced concrete side wall, the steel grid is welded on the steel base, and the asphalt layer is laid on the outside of the concrete side wall. This method causes a difference in elevation between the grille and the road surface, making it impossible to connect smoothly, causing uneven force on the grille when the vehicle rolls over it, poor driving comfort, and easily causing the grille to sink or bulge, resulting in damage to the road surface at the edge of the grille. When vehicles are ...
