Description

Technical Field

[0001] The utility model relates to the technical fields of water conservancy projects and anti-seepage technologies, and particularly relates to an opposing steel plate and water stop combined structure. Background Art

[0002] For large and medium-sized hydraulic structures, the filling height of the soil on the side of the pier wall facing the soil is high, and the lateral earth pressure is large. Usually, an empty box or an empty box and counterfort retaining wall is arranged on both sides of the main structure of the hydraulic structure to offset the lateral earth pressure. The empty box or the empty box and counterfort retaining wall can also serve as the foundation for the maintenance room or control room. However, the excavation range of the empty box or the empty box and counterfort retaining wall structure is large and the investment is high. Under the condition of being restricted by the construction red line or investment, the bottom slab and pier wall of the main structure of the hydraulic structure need to directly bear the lateral earth pressure.

[0003] Large and medium-sized hydraulic structures are usually multi-hole structures. Usually, two or three holes are connected in series and share a bottom slab. Due to the high filling height of the soil on the side facing the soil and the large lateral earth pressure, the lateral stability of the main structure of two or three holes connected in series on the side facing the soil may not meet the requirements of the specifications. Soft soil is widely distributed in the southeastern coastal areas of China. Most soft soil foundations have engineering characteristics such as deep soil layers, high natural water content, large void ratio, high compressibility, low bearing capacity, and under-consolidation. In order to prevent the settlement of hydraulic structures, pile foundations are mostly used for the foundation treatment of hydraulic structures on soft soil foundations. In this case, due to the fact that the pile foundation cannot provide a high horizontal bearing capacity in the case of soft soil foundation, it is more difficult for the lateral stability of the main structure of two or three holes connected in series on the side facing the soil to meet the requirements of the specifications.

[0004] The opposing steel plate is occasionally used when the anti-slip stability of the above-mentioned empty box or empty box and counterfort retaining wall cannot meet the requirements of the specifications, or to avoid damage to the main structure caused by contact and collision between the pump house of the pumping station and the adjacent structure during an earthquake.

[0005] There is generally a certain water head difference between the upstream and downstream of large and medium-sized hydraulic structures. When the water head difference is large, the anti-seepage and drainage layout is very important. Especially for pumping stations built on river and lake dikes or soft foundations, in order to prevent water from seeping into the pump house through the permanent deformation joint, water stop sheets (bands) with durable materials and reliable performance are usually buried in the underwater joint section. The specifications require that for important large pumping stations, two water stop sheets (bands) should be buried. The copper sheet water stop and the water swelling water stop band are generally used alone in small and medium-sized hydraulic structures as part of the anti-seepage system of the bottom slab and the structure. For large and medium-sized hydraulic structure projects, further improvement is needed.

[0006] If, on the premise that the functions do not affect each other, the opposing steel plate and the improved anti-seepage and water stop structures are combined to provide a combined structure that can offset the lateral earth pressure, ensure the lateral stability of the main structure of the hydraulic structure, and form a reliable anti-seepage system in the horizontal and vertical directions, it is particularly important.
