Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic building structures, and in particular relates to a prefabricated hollow box-type retaining wall component for a pump station intake pool. Background Technology

[0002] The water source booster pumping station project consists of an intake bell-shaped inlet, an inlet floodgate, a culvert through the dike, a forebay and intake pool, a pump house, and outlet pipelines. The forebay and intake pool are 86.0m long, divided into 8 sections. The first 7 sections are transitional sections, each 76.0m long, while the last 4 sections are horizontal sections, each 10.0m long. The side walls utilize buttresses and hollow box-type retaining wall structures. The hollow box-type retaining walls play a crucial role at the hydraulic gate inlet, forming the facade of the intake pool. Because the intake pool inlet directly connects to a lake or river, the geological characteristics of this area are silty soil with insufficient support strength. If solid retaining walls were used, uneven settlement could easily lead to wall cracking, leakage, or structural detachment.

[0003] Hollow box retaining walls have internal cavities filled with sand or other materials to balance the stress difference between the wall base and the foundation, reducing uneven foundation settlement and adjusting the distribution of foundation stress. Existing hollow box retaining walls have water inlets connecting the internal cavity to the outside, allowing water to enter and balance the weight; simultaneously, water is discharged promptly when the water level drops to further reduce its weight. However, in water flows with heavy siltation, the internal cavity can easily accumulate silt, leading to poor water flow and loss of the balancing function. Furthermore, silt and other impurities can easily clog the water inlets. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated hollow box-type retaining wall component for pump station inlet pool, which improves the smoothness of water inlet and outlet of the hollow box-type retaining wall and prevents silt blockage.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A prefabricated hollow box-type retaining wall assembly for a pump station intake pool includes a base plate. An installation groove is formed on the side of the base plate corresponding to the plate surface. Hollow box-type retaining walls are arranged and installed in the installation groove along the length direction. The retaining wall has a cavity inside. Inclined panels are distributed at intervals along the height direction in the cavity. The inclined panels are integrally formed with the inner sidewall of the cavity. The inclined panels divide the cavity into multiple uniform compartments. A water channel connecting the outer side is formed on the water-blocking side of the retaining wall corresponding to the compartment.

[0007] Furthermore, foundation piles are installed on the adjacent sides of the retaining wall. The foundation piles have a square cross-section, pass through the bottom slab, and extend deep into the foundation. The retaining wall has a chamfered groove on its side to accommodate and enclose the foundation piles.

[0008] Furthermore, a casting groove is provided at the bottom of the shaped groove, and a step is provided between the casting groove and the side wall of the shaped groove to limit the installation position of the foundation pile.

[0009] Furthermore, the backwater surface of the retaining wall is provided with adjustable reinforcing ribs and is equipped with buttresses, which are installed along the grooves between the reinforcing ribs for limiting their position.

[0010] Furthermore, the buttress has an arc-shaped groove on the contact side with the retaining wall surface, the base plate has a limiting groove at the bottom of the buttress, and the buttress has an opening on the bottom support side. The buttress also has circular weight-reducing holes.

[0011] This invention offers the following advantages: During the flood season, water flows along the water channel into the cavity, increasing the weight of the retaining wall and improving its water-blocking effect. During the receding season, water flows out along the water channel, reducing the weight of the retaining wall and achieving dynamic balance. The inclined panels within the cavity serve two purposes: firstly, as an internal reinforcing structure of the retaining wall, they improve its structural stability and water-blocking strength; secondly, they prevent the accumulation of silt in the cavity, allowing for rapid removal of silt and impurities and preventing clogging of the water channel.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1-3As shown: A prefabricated hollow box-type retaining wall assembly for a pump station intake pool, characterized in that: it includes a base plate 2, and an installation groove 21 is provided on the side of the base plate 2 corresponding to the plate surface position. Hollow box-type retaining walls 1 are arranged and installed in the installation groove 21 along the length direction. The retaining wall 1 has a cavity inside, and inclined panels 11 are distributed at intervals along the height direction in the cavity. The inclined panels 11 are integrally formed with the inner sidewall of the cavity. The inclined panels 11 divide the cavity into multiple uniform compartments. A water trough 12 communicating with the outside is provided on the water-blocking side of the retaining wall 1 corresponding to the compartment.

[0020] This retaining wall is a precast concrete structure. After the foundation is laid on the construction site, the base slab is poured and an installation groove is reserved. The retaining wall structure is then spliced ​​into the corresponding installation groove. The retaining wall is a wall structure with internal cavities for weight reduction. The retaining wall has steel reinforcement skeletons inserted into the wall surface on the water-retaining side and the back water-retaining side to improve the support performance.

[0021] The cavity is divided into multiple compartments by internal inclined panels. These panels slope towards the water-blocking side of the retaining wall, and the cross-sectional projection of each compartment is a parallelogram. A water channel connecting to the outside of the retaining wall is created at the lowest point of the inclined panel for water inflow and outflow. During the flood season, water flows into the compartments along the channel, increasing the weight of the retaining wall and improving its water-blocking effect. During the flood season, water flows out along the channel, reducing the weight of the retaining wall and achieving dynamic balance. The inclined panels within the cavity serve two purposes: firstly, they act as an internal reinforcement structure for the retaining wall, improving its structural stability and water-blocking strength; secondly, they prevent the accumulation of sediment in the compartments, allowing for rapid removal of sediment and impurities and preventing clogging of the water channel.

[0022] like Figures 1-2 As shown: Retaining wall 1 has adjacent foundation piles 3. The foundation piles 3 have a square cross-section, pass through the base slab 2, and extend deep into the foundation. The retaining wall 1 has a C-shaped groove 13 on its side to accommodate and enclose the foundation piles 3. The portion of the foundation pile passing through the base slab is cast and fixed to the base slab. The C-shaped grooves on both sides of the retaining wall can completely enclose the entire foundation pile. A casting groove 14 is provided at the bottom of the C-shaped groove 13. A stepped portion exists between the casting groove 14 and the side wall of the C-shaped groove 13 to limit the installation position of the foundation piles 3. The casting groove is used for cement pouring after the retaining wall is assembled and installed, improving sealing and structural stability.

[0023] like Figure 4 As shown: The backwater side of retaining wall 1 is provided with adjustable reinforcing ribs 15, and a buttress 4 is installed thereon. The buttress 4 is installed along the grooves between the reinforcing ribs 15 for limiting its position. This is used to improve the support strength of the backwater side of the retaining wall. This buttress is a right-angled triangular structure and is a prefabricated structure.

[0024] The buttress 4 has an arc-shaped groove 41 on its contact side with the retaining wall 1, and the base plate 2 has a limiting groove 22 on the bottom of the buttress 4. The buttress 4 also has a slot 42 on its bottom support side. Both the arc-shaped groove and the limiting groove are used for subsequent cement pouring after assembly, making the connection between the buttress, retaining wall, and base plate more stable. The width of the limiting groove is slightly larger than the thickness of the buttress. Multiple slots are opened at the bottom of the buttress for a more secure connection after pouring cement mortar. The buttress 4 has circular weight-reducing holes 43 to reduce the weight of the buttress and decrease pressure on the base plate.

[0025] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
