Description

Large-diameter steel cylinder water taking platform structure and construction method thereof

Technical Field

The invention relates to the technical field of water taking and draining engineering, in particular to a large-diameter steel cylinder water taking platform structure and a construction method thereof.

Background

Water intake systems typically include a water intake, a water intake pipe, and a water intake pumping station. The water intake is arranged on water, the water intake pump station is generally arranged in the rear land area, the water intake pipe and the water intake pump station are connected through the water intake pipe, and the water intake pipe needs to penetrate through the revetment. However, in the actual planning of the water intake system, the restriction of factors such as narrow land space and geological conditions is often faced, and the water intake system cannot be normally arranged on land. Therefore, the scheme of arranging the water taking system on the water is developed. Water intake systems located above water generally have two arrangements: one is that the water intake is located in the deep water area, and the water intake pump station is located in the near-shore shallow water area; the other is to combine the water intake and the water intake pump station and locate the water intake and the water intake pump station in a proper water depth area. It is worth noting that the structural design and construction of the water intake pump station of any water intake system arranged on water are far more complex and more demanding than those of water intake systems arranged on land.

The water intake system arranged on water generally adopts a cast-in-place reinforced concrete structure, a reinforced concrete caisson or a prefabricated reinforced concrete caisson structure and the like. For example, chinese patent (CN 103866817A) discloses a water intake pump station. This water intaking pump station, including water intaking platform, pile foundation and water intaking pump, the water intaking platform sets up on the pile foundation, the water intaking pump sets up on the water intaking platform. The water taking pump station does not need to be provided with an underground pump room, can directly install the pump on the water taking platform, has small overall engineering quantity, no underwater construction engineering quantity, low investment, convenient construction and short construction period, and is particularly suitable for water source places with poor riverbank geological conditions, thick silt layers and slow water flow. However, (1) because the water taking pump directly takes water from an open water area, a relatively stable water source environment does not exist, the operation of the water taking pump is possibly influenced by factors such as waves, water flow and the like, the vibration of the water taking pump occurs, and the water taking efficiency and the service life of the water taking pump are further influenced; (2) if the one-time deposition amount is large, the water taking of the water taking pump can be influenced when the clear distance between the mud surface below the water taking platform and the water inlet of the water taking pump cannot meet the requirement of normal operation of the water taking pump; (3) the pile foundation adopted by the method needs to pile large area underwater, the underwater connection design is difficult, the pile has a straight pile and an inclined pile, the depth is deep, the construction risk is high, the difficulty is large, and the construction cost is high.

Further, as disclosed in chinese patent (CN 104775398B), a water intake structure for a box-tube foundation siphon gallery and its application, including a box-tube foundation structure inserted into the soil body, and a siphon gallery connected to the same as a whole, the box-tube foundation structure includes a plurality of equal-diameter, equal-height, bottomless cylinders, the cylinders are connected by a connecting wall between each two cylinders, a top cover plate is disposed on the top of the cylinder and the enclosed interval, a box-tube foundation through hole capable of being opened and closed is disposed on the top cover plate, and the siphon gallery includes a middle partition wall, an upper covering wall, a vertical wall, an energy dissipation pool, an energy dissipation wall, a rib plate preformed hole and a siphon gallery through hole. However, the reinforced concrete caisson has heavy weight and higher requirement on the bearing capacity of the foundation. Especially for soft soil foundation, the caisson foundation needs foundation treatment, and the construction difficulty on water is larger. From the structural stress, the underground structure of the reinforced concrete water taking pump station is a water-tight underwater structure, the influence on the surrounding water flow is easily generated, the integral structure is greatly influenced by the wave force and the water flow force, the structural design difficulty is high, and the engineering investment is high. And thirdly, the water intake pipeline/port is of an independent structure, so that the construction complexity is further increased, the construction period is prolonged, and the cost is increased.

In combination with the above, in the field of actual water taking and drainage engineering, although there are various water taking system structures and construction methods arranged on water, the conventional water taking system has high requirements on the foundation conditions of the arrangement site, and requires high investment cost for foundation treatment. Particularly, when the soft soil geological arrangement with large deposition and limited water depth is realized at one time, the traditional water taking platform structure and the construction method thereof have high design and construction difficulty, high manufacturing cost and limited arrangement scene of a water taking system.

Therefore, a large-diameter steel cylinder water taking platform structure and a construction method thereof are needed.
