Problems solved by technology

However, it is only suitable for construction on slopes. When the bank slope is steep, the revetment has poor adhesion and is easy to fall off; it is not conducive to sediment deposition, and the wave dissipation range is small. The seepage hole is in contact with the impact water flow during the discharge process. The damage and collapse of the structure caused by the easy loss of sand and soil, the green area is small and a large amount of raw materials are required to be piled up

Embodiment 1

[0028] like Figure 1-7 As shown, the sea reclamation embankment revetment structure includes a main body 1 and two buried piles 2, the main body 1 contains a square brick body 11, and the lower surface 111 of the brick body 11 contains two limit grooves that are the same in number as the buried piles 2 and cooperate with each other 115; the opposite surface of the lower surface 111 is the upper surface 112; the buried pile 2 is located on the adjacent side of the lower surface 111 of the brick body 11 or the upper surface 112; the opposite side of the installation surface of the buried pile 2 is composed of eight partitions 141 distributed at intervals Wave-reducing slope 14. The L-shaped buried piles 2 of the revetment structure of the sea reclamation embankment protrude from the main body 1, and the buried piles 2 are buried in the sand layer as a whole to increase the grip, improve the strength and reduce the use of raw materials. The matching limit groove 115 acts as a l...

Embodiment 2

[0039] like Figure 8-9 As shown, the revetment structure of the sea reclamation dam is basically the same as that of Embodiment 1, the difference is that this embodiment is built with a steep wall embankment, does not contain the slope platform 13 and the green platform 131, and adds a positioning boss 15, changing the limit slot 115 position, when lapping, the cooperation between the buried pile base 21 and the limiting groove 115 in Embodiment 1 is converted into the cooperation between the positioning boss 15 and the limiting groove 115 so that it is not easy to produce lateral displacement gaps to cause sand loss and avoid collapse. Easy to lap. Compared with the construction of slope embankment revetment in Example 1, it can reduce the occupied area, and also has strong surface grip, the water and soil are not easy to be lost, and the structure is stable, which helps to weaken the strong wind and current attack and promote the sediment on the beach. It can be used to pl...

Embodiment 3

[0041] When the revetment structure of the sea reclamation embankment of the present invention is actually used, when building the bank revetment of the slope embankment, the construction personnel lay revetment blocks on the pre-laid compacted sand layer or soil layer embankment, and fill the buried pile 2 and the embankment with sand and soil. Compaction is performed in cavities formed between layers of silt or soil. Adjacent bank revetment blocks are overlapped horizontally, so that the buried pile bases 21 of the upper and lower bank revetment blocks are respectively snapped into the limit grooves 115 of two different revetment blocks to limit the overall structure, so that the overall structure is more uniformly stressed, reducing The occurrence of cracks and structural damage. The first seepage pipe 121 and the second seepage pipe 1141 can cooperate with the culvert 113, the second seepage hole 22 and the first seepage hole 116 when the revetment is lapped to form a seep...

Abstract

The invention discloses a coastal dam revetment structure, and belongs to the field of water conservancy projects. The coastal dam revetment structure comprises a main body and a plurality of embeddedpiles, the main body comprises a square brick body, a lower surface of the brick body is provided with limiting grooves with the same number as the embedded piles, and an opposite side of an embeddedpile mounting surface is provided with a wave reducing slope formed by a plurality of partition plates distributed at intervals; an upper part of the wave reducing slop selectively contains a slope platform or positioning bosses; a plurality of concave greening platforms are arranged on the slope platform, bosses and grooves which are matched with each other are further arranged on an upper surface and a lower surface of the brick body, and a water seepage channel formed by a culvert, water seepage holes and a water seepage pipeline in a penetrating mode is arranged inside the brick body. Theearth surface holding power and the connecting strength of the revetment are enhanced, collapse is not likely to happen, lap stress deformation is small, and the structural stability is high; seepagewater can be drained quickly, sandy soil is not prone to loss, reduction of stormy wave impact and sediment erosion is facilitated, sediment silting is promoted, sheltering is provided for organisms,plant irrigation is facilitated, the ecological effect and the landscape effect are good, quick installation is facilitated, the service life of the revetment is long, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering, and in particular relates to a bank revetment structure for sea reclamation dikes and dams. Background technique [0002] Bank revetment is an engineering measure to artificially reinforce the coast slope, which can effectively prevent the invasion of waves, water currents, washing and groundwater, and maintain the stability of the coastline. The existing revetment forms in our country can be divided into three types: engineering revetment, landscape revetment and ecological revetment. Engineering bank revetment is a rigid engineering revetment, which has good durability and small seepage loss, but also destroys the original natural ecological system of the bank slope and its corresponding functions. Landscape revetment can satisfy people's visual sensory enjoyment and provide people with a water-friendly space, but it also has a destructive effect on the natural ecosystem of the ban...
