Description

TECHNICAL FIELD

[0001] The utility model belongs to geotechnical engineering technical field, and specifically relates to a slope retaining wall combination water fall energy dissipation structure. BACKGROUND

[0002] In the field of geotechnical engineering, the stability of the slope is directly related to the safety and service life of the project. The traditional slope design mainly focuses on the mechanical stability, that is, through reasonable slope, reinforcement measures and support structure to ensure that the slope will not slide or collapse due to gravity. However, practice shows that it is not enough to only ensure the mechanical stability, and the drainage design also plays a decisive role in the long-term stability of the slope. However, in the conventional slope design, the drainage design is often ignored, which may lead to high water content in the internal soil of the slope, and the high water content will reduce the shear strength of the soil and increase the pore water pressure of the soil, thereby weakening the stability of the slope. In addition, high water content may also cause the deformation of the slope to intensify, and even cause slope failure, such as landslides, mudslides and other disasters.

[0003] In order to solve the above problems, the traditional slope drainage design usually sets a drainage ditch on the slope surface to collect and discharge surface water. However, when the water flow in the drainage ditch is too large, it will cause erosion to the soil at the slope toe or to the retaining wall at the slope toe, and will also affect the stability of the slope to some extent.

[0004] Therefore, there is a need for a slope retaining wall combination water fall energy dissipation structure that can effectively discharge surface water outside the slope range and ensure the stability of the slope. SUMMARY

[0005] The utility model aims at providing a slope retaining wall combination water fall energy dissipation structure that can effectively discharge surface water outside the slope range and ensure the stability of the slope.

[0006] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of:

[0007] A slope retaining wall combination water fall energy dissipation structure, comprising a slope surface water fall arranged along the inclined direction of the slope surface, a retaining wall water guide pipe arranged inside the retaining wall at the slope toe and inclined downward, and an energy dissipation pool arranged outside the retaining wall and buried in the soil below the slope toe. The upper and lower ends of the retaining wall water guide pipe are respectively connected with the lower end of the slope surface water fall and the side wall of the energy dissipation pool close to the retaining wall. The side walls on the front and rear sides of the energy dissipation pool are respectively provided with a slope toe drainage ditch in communication with the inside thereof, and the slope toe drainage ditch is arranged along the length direction of the slope toe of the retaining wall.

[0008] The further improvement in the technical scheme of the utility model lies in that: the slope water-drop comprises a water-drop groove opened along the slope direction of the slope surface, and a plurality of energy dissipation steps arranged uniformly along the slope direction in the water-drop groove and an energy dissipation platform arranged at the bottom of the last energy dissipation step.

[0009] The further improvement in the technical scheme of the utility model lies in that: the upper and lower ends of the retaining wall water guide pipe are integrally formed with a bell mouth and an elbow respectively; the retaining wall water guide pipe is connected with the energy dissipation platform of the slope water-drop through the bell mouth at the upper end, and the elbow at the lower end of the retaining wall water guide pipe is connected with the side wall of the energy dissipation pool near the retaining wall through a drainage cross pipe; the drainage cross pipe is perpendicular to the slope toe drainage ditch on the front and back sides of the energy dissipation pool in the horizontal direction.

[0010] The further improvement in the technical scheme of the utility model lies in that: the caliber of the bell mouth of the retaining wall water guide pipe is larger than the width of the water-drop groove; the retaining wall water guide pipe can adopt cast iron pipe or PVC pipe.

[0011] Thanks to the above technical scheme, the utility model has the following technical progress:

[0012] The slope retaining wall combined water-drop energy dissipation structure can effectively concentrate the slope surface and slope top runoff out of the slope range, guide the water flow and dissipate the water flow energy, reduce the influence of the surface water on the slope, and ensure the stability of the slope.

[0013] The slope water-drop adopted by the utility model effectively slows down the water flow speed, reduces the water and soil loss, and protects the stability of the slope through the design of the water-drop groove and the energy dissipation step.

[0014] The retaining wall water guide pipe adopted by the utility model can smoothly guide the water flow through the design of the bell mouth and the elbow, avoids the direct scouring of the water flow on the foundation of the retaining wall, and thus improves the stability of the retaining wall.

[0015] The energy dissipation pool adopted by the utility model can effectively dissipate the energy of the water flow, reduces the scouring of the water flow on the downstream soil body through the falling and diffusion of the water flow.

[0016] The slope toe drainage adopted by the utility model can timely drain the accumulated water in the energy dissipation pool, prevent the accumulated water from causing adverse influence on the foundation of the retaining wall, and also helps to keep the soil body behind the retaining wall dry and prevent the soil body from softening.
