Description

Slope protection structure with stilling pool at urban river channel

Technical Field

The utility model relates to a slope protection structure in urban river course department area stilling basin. Is suitable for the field of ecological restoration engineering.

Background

The stilling pool is a building for dissipating energy in the process of water conservancy project drainage, so that energy carried by the drainage water flow is consumed on turbulence in the water flow, energy exchange and friction between the drainage water flow and surrounding water bodies and the side wall of the building as much as possible, and local scouring endangering safety is not generated on a river bed and a bank slope, so that the drainage water flow is stably connected with the downstream, and the normal operation of other buildings is not influenced. The stilling basin can quickly change the downward flow into the slow flow, generally can eliminate the kinetic energy of the downward flow by 40-70 percent, can shorten the length of the apron and is an effective and economic energy dissipation facility.

In order to ensure the safety of the river channel, corresponding energy dissipation facilities need to be built in the rainwater drainage projects newly built in the urban river channel, and corresponding stilling ponds can be built in the river channel. The urban river comprehensive treatment gives consideration to multiple functions of flood control, waterlogging drainage, landscape, hydrophilicity and the like, hydrophilic slow-walking footpaths are mostly built on slopes on two sides in the river, and a stilling pool built along with rainwater drainage port engineering is often closer to the slow-walking footpaths, so that the landscape quality of the river can be greatly reduced, and the experience of tourists is influenced.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be described in further detail below with reference to the accompanying drawings by way of examples, which are illustrative of the present invention and are not intended to limit the present invention.

This embodiment is a slope protection structure in urban river course department area stilling pond, has river course structure 1 and stilling structure 2, and stilling structure 2 arranges in river course structure 1. The river channel structure 1 has a main channel 101, an upstream wall 102, a walkway 103, a slope wall 105 and a slope 106 arranged in sequence from the river channel to the road surface, and a railing 104 is arranged on the upstream wall 102, wherein the walkway 103 is higher than the main channel 101 by about 0.7-1.5 m. Therefore, the river channel slope protection retaining wall 105 can effectively prevent soil in the river channel slope protection 106 from flowing onto the travelator 103 under the action of rainwater and other water flows to influence pedestrians on the traveller 103, and is beneficial to maintaining the water and soil retaining capacity and good landscape effect of the river channel slope protection 106; the upstream surface retaining wall 102 of the travelator can effectively prevent soil in the travelator 103 from causing water and soil loss under the scouring of water flow in a river channel, is favorable for keeping the water and soil stability on the travelator 103, and can effectively prevent pedestrians from falling into the river channel under the combined action of the railings 104 on the upstream surface retaining wall 102 of the travelator.

In this embodiment, the stilling structure 2 has a stilling pool 201 disposed below the walking path 103 and a rainwater pipeline drainage structure 3 connected between a water inlet end of the stilling pool 201 and a municipal rainwater pipeline network. Rainwater pipeline drainage structures 3 have one end and connect outlet pipe 303 and one end at the pond 201 that disappears of 201 water inlet end and connect inlet tube 301 on the fashion rainwater pipe net, connect through the stand pipe of vertical arrangement in river course bank protection 106 at outlet pipe 303 and inlet tube 301's junction, and the interface of outlet pipe 303 is arranged in the below of inlet tube 301 interface. Therefore, when rainwater passes through the guide pipe, the speed and impact force of water flow entering the stilling pool are relieved, the size of the stilling pool body 201 is convenient to reduce, and the smaller stilling pool body 201 can maintain the energy dissipation of a certain amount of rainwater.

Further, the stilling pool body 201 has a stilling pool side wall 204 and a stilling pool bottom plate 205 arranged below the travelator 103. Thus, rainwater flowing into the stilling pool body 201 through the rainwater pipeline drainage structure 3 can be effectively prevented from permeating into soil below the walking way 103. A mounting hole for mounting a water outlet pipe 303 is formed in a stilling pool side wall 204 on one side, far away from a river, of the stilling pool body 201, and is used for discharging rainwater passing through a rainwater pipeline drainage structure 3 into the stilling pool; an energy dissipation sill 202 is arranged on a stilling pool side wall 204 close to one side of the river channel in the stilling pool body 201, and a water outlet 203 leading to the river channel is formed in the stilling pool side wall 204 above the energy dissipation sill 202. So, the rainwater that enters into the energy dissipation cell body through outlet pipe 303 discharges from outlet pipe 303 and dashes to energy dissipation bank 202 on, the energy dissipation bank 202 of absorption cell body 201 has played good energy dissipation effect in the face of the rainwater of straight rushing energy dissipation bank 202, and energy dissipation bank 202 has played the guide effect to rivers simultaneously, has reduced the frontal impact of rivers, with the reverse guide of rivers, carries out the energy dissipation to later rivers, has improved the energy dissipation effect that the energy dissipation pool was carried greatly. Thus, the volume of the stilling cell body 201 can be further reduced. Rainwater flow after energy dissipation through the energy dissipation sill 202 is discharged into the river channel through the water outlet 203 above the energy dissipation sill 202, so that rainwater in the municipal rainwater pipeline can be dissipated at the hidden position and is discharged into the river channel, and good landscape is kept.

In this embodiment, for the convenience of personnel to overhaul the energy dissipation cell body, a passageway leading to the energy dissipation cell body is arranged on the travelway 103, and a sealing cover structure 4 is arranged at the passageway. The cover structure 4 has a mounting frame 401 fixedly mounted at the passage, and a cover plate 402 fitted to the mounting frame 401 is mounted on the mounting frame 401. In order to maintain good landscape and facilitate the use of the person, a handle insertion groove 403 is formed on the upper side surface of the cover plate 402, and a pulling handle 404 is installed at the handle insertion groove 403. Thus, when the cover 402 does not need to be pulled, no protrusion is generated on the cover 402, which affects the pedestrian on the walkway 103.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
