Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cyanamide production, in particular to a high drop-difference water well. Background Art
[0002] The converter stations or substation projects currently under construction are getting closer and closer to the western mountainous canyon areas, resulting in very high and steep slopes in the station area. Whether rainwater and mountain torrents in the station area can be safely discharged has become a key factor affecting the safety and stability of the station site and slopes.
[0003] Drainage in high slope sites usually faces problems such as high drainage drop, large area occupied by drainage facilities, and poor safety. Utility Model Content
[0004] The utility model aims to provide a high-drop drop well to solve the technical problems in the prior art that drainage of high slope sites usually faces, such as high drainage drop, large area of drainage facilities, and poor safety.
[0005] The utility model discloses a high-drop drop well, comprising a first well chamber and a second well chamber, wherein the lower part of the first well chamber is connected with the upper part of the second well chamber through a culvert, the culvert has a length of 1-1.4 m, energy dissipation layers are arranged at the bottom of the first well chamber and the second well chamber, and the first well chamber and the second well chamber are both rectangular parallelepipeds.
[0006] Working principle: When in use, the drainage from the high slope site first enters the first well chamber, where the energy dissipation layer of the first well chamber eliminates part of the potential energy of the waterfall, and then enters the second well chamber through the culvert, where the energy dissipation layer of the second well chamber eliminates part of the potential energy of the waterfall again. By setting up the culvert, the effect of the hydraulic jump can be offset. By setting up the first well chamber, the second well chamber and the energy dissipation layer, the potential energy of the waterfall can be eliminated and the height difference of the waterfall well can be increased.
[0007] Furthermore, the culvert has a length of 1.2 m.
[0008] By setting the culvert length, the adverse effects of sporadic hydraulic jumps can be reduced so that they will not affect the downstream waterfall wells.
[0009] Furthermore, the energy dissipation layer is a graded pebble layer.
[0010] By setting the energy dissipation layer as a graded pebble layer, it is possible to dissipate energy and prevent direct scouring of the bottom of the well. At the same time, the pebble layer can be replaced. After years of long-term scouring, the pebble layer can be replaced to ensure that the function of the well is not affected.
[0011] Furthermore, the thickness of the energy dissipation layer is 500-700 mm.
[0012] Furthermore, the thickness of the energy dissipation layer is 600 mm.
[0013] Furthermore, the lengths of the first well chamber and the second well chamber are 1.7 m to 2.2 m.
[0014] By setting the length of the first well chamber and the second well chamber, 83% of the floor space can be saved, and the layout can be more flexible when designing drainage for engineering slopes or steep slopes.
[0015] Furthermore, the width of the first well chamber and the second well chamber is 1.1-1.3 m.
[0016] Furthermore, the width of the first well chamber and the second well chamber is 1.2 m.
[0017] Furthermore, the height of the first well chamber and the second well chamber is 2-8.5m.
[0018] By setting the height of the first well chamber and the second well chamber, the maximum drop of this type of well can reach 17m, far exceeding the 2.5m drop of the national standard atlas waterfall well. The drop is increased by 5 times, making it suitable for drainage of high slopes and steep banks.
[0019] Furthermore, the bottom of the drop well is provided with reinforced reinforcement.
[0020] The strength of the well is improved by setting up reinforced reinforcement.
[0021] Furthermore, a raft foundation is provided below the drop well.
[0022] Uneven settlement can be effectively prevented by setting up a raft foundation.
[0023] Furthermore, the water-facing surfaces of the first well chamber and the second well chamber are provided with scour-resistant layers.
[0024] By setting up an erosion-resistant layer, the erosion of water on the inner wall of the well can be eliminated.
[0025] Furthermore, the erosion-resistant layer is a polymer panel.
[0026] By setting the erosion-resistant layer as a polymer panel, it can be replaced in sections regularly, making inspection and maintenance very convenient.
[0027] Furthermore, the polymer panel is a polyethylene board.
[0028] Furthermore, the first well chamber and the second well chamber have the same size.
[0029] Furthermore, the first well chamber is connected to a drainage ditch or a water pipe.
[0030] Furthermore, the second well chamber is connected to a drainage ditch or a water pipe.
[0031] Compared with the prior art, the utility model has the following beneficial effects:
[0032] 1. By installing culverts, the effect of hydraulic jump can be offset;
[0033] 2. By setting the first well chamber, the second well chamber and the energy dissipation layer, the potential energy of the waterfall can be eliminated and the height difference of the waterfall well can be increased;
[0034] 3. By setting the length of the side of the culvert connected to the first well chamber and the second well chamber, 83% of the floor space can be saved, and the layout can be more flexible when designing drainage on engineering slopes or steep slopes;
[0035] 4. By setting the height of the first well chamber and the second well chamber, the maximum drop of this type of well can reach 17m, far exceeding the drop of 2.5m in the national standard atlas of the waterfall well, and the drop is increased by 5 times, which is suitable for drainage of high slopes and steep slopes;
[0036] 5. By setting up the scouring-resistant layer, the scouring of water on the inner wall of the well can be eliminated;
[0037] 6. By setting the erosion-resistant layer as a polymer panel, it can be replaced in sections regularly, making inspection and maintenance very convenient;
[0038] 7. Uneven settlement can be effectively prevented by setting up a raft foundation. BRIEF DESCRIPTION OF THE DRAWINGS
