Abstract
Description
Technical Field
[0001] This utility model relates to the field of water intake and drainage engineering technology, and in particular to a mushroom-shaped water intake and drainage structure with a vertical caisson at the top circular center. Background Technology
[0002] Currently, municipal water plants, power plants (including nuclear power plants) and related projects require a large amount of water intake and drainage to meet the cooling needs of generator sets.
[0003] The intake and drainage head structure is the core of an intake and drainage project. Conventional intake and drainage head structures generally take two forms: multi-point intake and drainage, and single-point intake and drainage. Multi-point intake and drainage typically employs a jacking riser system within the intake and drainage tunnel. However, due to limited space within the tunnel, as the tunnel depth increases, the riser often struggles to penetrate the upper soil layer. Therefore, conventional multi-point intake and drainage schemes suffer from limitations such as the inability to allow for excessively deep tunnels and the excessive area occupied by multiple intake points. Single-point intake and drainage schemes, on the other hand, require a large single intake cross-section. Given the high water pressure in aquatic environments, ensuring a large intake cross-section while maintaining the stability of the intake and drainage structure is a significant challenge. Furthermore, single-point intake and drainage head structures are often complex and may exhibit unreasonable functional area distribution. Utility Model Content

The water intake and drainage structure is mushroom-shaped as a whole.
[0031] See Figure 1 and Figure 3 The upper intake and drainage expansion head wall 9 includes an outer wall, which is a circular wall and is the outermost ring of walls. Wall 9 also includes an inner wall, which is the innermost wall. The inner wall and the lower structure 10 are connected as a single unit, forming the central vertical intake and drainage channel well. The intake and drainage channel well can be prefabricated and transported to the site for installation during construction. A base plate 14 is provided at the bottom of the intake and drainage channel well. Wall 9 can also be equipped with intermediate walls as needed. Some areas that do not require water passage can be partitioned using intermediate walls, for example... Figure 1 The upper part of the water intake and drainage expansion head is divided into two horizontal intermediate walls, one above the other, for example. Figure 3 The middle section consists of three vertical walls. In addition, wall 9 also includes a top wall and a bottom wall.
[0032] See Figures 1 to 3 The exterior wall has an intake and drainage window 1 that connects to an external water body, and the intake and drainage window 1 is higher than the muddy surface at the bottom of the water body. In this embodiment, the intake and drainage window 1 is opened in a local arc range of the exterior wall. A grille is installed at the intake and drainage window 1, and the specific installation method is as follows: the exterior wall is provided with a grille groove 2, and the grille is installed in the grille groove 2 in a pull-out manner for easy removal and cleaning.
[0033] See Figure 1 The inner wall is equipped with a gate that connects the water body and the intake and drainage channel well. A gate 13 can be placed at the gate. The gate 13 is used during maintenance to block the external water flow. The gate 13 is not placed during normal operation of the intake and drainage system. The inner wall has a vertical gate slot 3 at the corresponding position of the gate. The gate slot 3 connects to the top surface of the upper intake and drainage expansion head. During maintenance, the gate 13 is lowered down from the gate slot 3 on the top surface to isolate the external water body and provide dry maintenance conditions inside.

A wave-blocking railing, consisting of a wave-blocking wall 5 and a wave-blocking gate 6, is installed along the edge of the top surface of the upper intake and drainage expansion head. The wave-blocking gate 6 can be opened to facilitate access for personnel or machinery. An inspection port 4, covered with a cover, is also provided on the top surface of the upper intake and drainage expansion head at the location corresponding to the intake and drainage channel well, facilitating maintenance by personnel.
