Problems solved by technology
[0002] At present, in the design and construction of roads, it is common to encounter areas with steep slopes on one side of the road and relatively large water drop. Due to the steep slope, fast water flow, and strong scouring force, the existing drop wells are severely eroded. In order to The slowing water drop well is damaged due to severe erosion, and mortar blocks or cement concrete are usually used to reinforce the masonry, which increases the amount of construction and brings inconvenience to the construction, but does not improve and adjust the structure. , the water flow directly falls on the bottom of the falling well. In the process of flowing into the falling well, without energy dissipation and changing the direction of the water flow, it will cause serious erosion to the falling well. Therefore, a process of water flowing through the falling well is required. In the middle, the water flow is used to dissipate energy and change the flow direction to reduce the erosion of the water flow on the water drop well.

Embodiment Construction
[0014] The present invention will now be described in further detail in conjunction with the accompanying drawings, which are simplified schematic diagrams, only schematically illustrating the basic structure of the present invention, and therefore only show the configurations related to the present invention.
[0015] Such as figure 1 The preferred embodiment of the damping brush drop well of the present invention shown includes a side ditch 1 and a drop well 2, the side ditch 1 is located at the top of the drop well 2, and the inner walls on both sides of the drop well 2 are provided with mutually misaligned As for the protrusion 3, the lower end of the drop well 2 communicates with the road drainage pipe 5. Preferably, the protrusion 3 is triangular, and preferably, the protrusion 3 is semicircular. The gutter 1 is provided with crushed stones, and the falling well 2 is connected to the road drainage pipe 5 in the roadbed 6 through a section of rising pipeline 4 . The lowe...

The invention discloses a drop well having a scouring alleviation function. The drop well comprises a gutter and a drop well unit; the gutter is arranged at the top of the drop well unit; the inner walls on the two sides of the drop well are provided with projections which are arranged in a stagger manner; and the lower end of the drop well unit is communicated with a road drainpipe. The inner walls on the two sides of the drop well having the scouring alleviation function are provided with the projections which are arranged in a stagger manner, so that the potential energy and kinetic energy of the water flow can be alleviated, and the energy of the water flow is gradually weakened when the water flow continuously bumps into the projections on the inner walls of the two sides of the drop well unit, and therefore the scouring on the drop well is alleviated. The projections on the inner walls of the two sides of the drop well unit are arranged in a stagger manner, so that the flow direction of the water flow changes continuously, the energy of the water flow is further weakened, and the scouring on the drop well is further alleviated.
Description
technical field [0001] The invention relates to a road facility, in particular to a water well for reducing buffer falls. Background technique [0002] At present, in the design and construction of roads, it is common to encounter areas with steep slopes on one side of the road and relatively large water drop. Due to the steep slope, fast water flow, and strong scouring force, the existing drop wells are severely eroded. In order to The slowing water drop well is damaged due to severe erosion, and mortar blocks or cement concrete are usually used to reinforce the masonry, which increases the amount of construction and brings inconvenience to the construction, but does not improve and adjust the structure. , the water flow directly falls on the bottom of the falling well. In the process of flowing into the falling well, without energy dissipation and changing the direction of the water flow, it will cause serious erosion to the falling well. Therefore, a process of water flow...
