Embodiment

[0034] During specific implementation, the sand settling box 1 and the movable sandbox 2 can be poured into such as with reinforced concrete figure 1 with Figure 4 the shape shown. Then dig a pit with the same shape as the sand box 1 and the movable sand box 2 on the side of the road, and the sand box 1 is buried in the pit, and the top surface of the sand box 1 is flush with the ground or slightly lower than the ground. Active Sandbox 2 as figure 1 with figure 2 As shown, it is placed in the pit below the sand outlet 6. The sand settling box 1 includes a water inlet 3 and a water outlet 4, the water inlet 3 is connected with the first-level sand settling box 14, the first-level sand settling box 14 is adjacent to the second-level sand settling box 15, connected by a partition 7, and separated The plate 7 is provided with a water outlet 11, and the first-level sand settling box 14 and the second-level sand settling box 15 are all provided with a sand discharge port 6. S...

Abstract

The invention discloses a method and a device for arranging a highway desilting basin. An integral desilting tank is adopted to replace an existing highway desilting basin, the undersurface of the desilting tank is an oblique face, the tank wall on one side of a lowest point of the oblique face is provided with a sand discharging port, a movable sand tank is arranged below the sand discharging port, and a flashboard is arranged at the sand discharging port. When sand discharging is needed, the flashboard is taken away to enable sand which precipitates at the bottom of the desilting tank to slide into the movable sand tank along the oblique face at the bottom of the desilting tank, and then the sand in the movable sand tank is poured away. Desilting effect is improved by means of lowering water flow speed and increasing water flow path, turbidity of water flower due to the fact that silt which is precipitated already is remixed into water flow in the process of desilting can be avoided, and desilting effect is good. A user only needs to clean the sand in the movable sand tank during desilting, so that convenience in cleaning is realized.

Description

technical field [0001] The invention relates to a method and a device for setting up a road grit chamber, and belongs to the technical field of water and soil conservation. Background technique [0002] my country is generally a country with severe drought and water shortage, and the distribution of rainwater is uneven in time and space. At present, various regions have paid special attention to soil and water conservation. Drainage and water interception have become indispensable water and soil conservation measures in highway engineering. In order to avoid drainage A large amount of sand carried by the water will cause harm to downstream residential areas and farmland. It is an effective protective measure to arrange grit chambers at a certain distance from the exit of road side ditches, drainage ditches or intercepting ditches. [0003] The grit chambers widely used in highway engineering currently mainly have the following cross-section forms, rectangular, trapezoidal, an...
