Description

Technical Field

[0001] The invention relates to a trash rack structure of an underwater water inlet and a construction method thereof, which are applicable to the technical field of building construction. Background Art

[0002] At present, trash racks need to be installed in river channels and reservoir channels to filter larger impurities in the water flow to avoid blockage. The conventional arrangement of trash racks at water inlets is to set trash rack grooves on both sides of the channel, lift the trash racks through the opening and closing equipment, and install the trash racks in the trash rack grooves. For the water inlet structure that takes water from the reservoir, its water inlet is arranged underwater, and it is not convenient to set up a trash rack groove at its water inlet, so it is not convenient to insert the trash rack at the water inlet. Due to the short time for emptying the reservoir or the inability to empty it, some trash racks do not have the conditions for dry land installation, so the trash rack installation operation needs to be carried out underwater, which is very difficult to construct. Summary of the invention

[0003] The technical problem to be solved by the present invention is: In order to solve the above technical problem, the present invention provides a trash rack structure of an underwater water inlet and a construction method thereof.

[0004] The technical solution adopted by the present invention is: a trash rack structure of an underwater water inlet, comprising:

[0005] The trash rack body is arranged inside the water inlet, and connecting plates are installed at both ends of the trash rack body, and mounting holes are formed on the connecting plates;

[0006] The mounting plate is arranged inside the water inlet at the position matching the connecting plates at both ends of the trash rack body. The mounting plate is installed with fixing bolts at positions corresponding to the mounting holes on the connecting plates, and nuts are installed on the fixing bolts passing through the mounting holes. In this way, during the construction of the water inlet, the mounting plate is fixed inside the water inlet, so that when the trash rack body is arranged at the water inlet position, the mounting holes on the connecting plates on both sides of the trash rack body are matched with the fixing bolts on the mounting plates on both sides of the water inlet, and the trash rack body is installed at the water inlet by installing nuts on the fixing bolts passing through the connecting plates and tightening them.

[0007] A first frame plate is installed between the connecting plates at both ends of the trash rack body, a second frame plate is installed on the trash rack body at a position corresponding to the first frame plate, and reinforcing ribs are installed between the first frame plate and the second frame plate. In this way, the structural strength of the trash rack body can be effectively enhanced.

[0008] The trash rack body is formed by welding at least two vertical bars and at least two transverse bars.

[0009] The trash rack body is composed of at least two trash rack monomers. In this way, when the water inlet is large in size, the trash rack body can be manufactured, transported and installed in sections by installing multiple trash rack monomers at corresponding positions of the water inlet to form the trash rack body.

[0010] The fixing bolts are arranged along the axial direction of the water inlet. Thus, when the trash rack body is installed in the water inlet and the trash is trapped, the fixing bolts are subjected to axial pressure and are not easily damaged.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and by way of examples. The following examples are intended to explain the present invention but the present invention is not limited to the following examples.

[0031] The invention relates to a trash rack structure of an underwater water inlet.

[0032] In this embodiment, there is a first concrete structure 1, which is constructed during the low water level period of the reservoir. During the construction of the first concrete structure 1, a water inlet is reserved, and second anchor bars 3 are embedded at both sides of the water inlet. After the construction of the first concrete structure 1 is completed, a baffle 7 is installed at the water inlet position on the first concrete structure 1. In this way, during the construction process in the water inlet, water can be effectively prevented from flowing into the water inlet after the water level of the reservoir rises.

[0033] In this embodiment, the water pipe 2 is constructed at the water inlet of the first concrete structure 1 to facilitate subsequent personnel to enter the water inlet through the water pipe 2 .

[0034] In this embodiment, installation positions of the second concrete structure 4 are reserved at both sides of the water inlet in the first concrete structure 1, and second anchor bars 3 are embedded in the first concrete structure 1 at the installation positions of the second concrete structure 4. In this way, after entering the water inlet, personnel can construct the second concrete structure 4, and the second concrete structure 4 is fixedly connected to the first concrete structure 1 under the action of the second anchor bars 3.

[0035] In this embodiment, a mounting plate 9 is installed on the second concrete structure 4, and a first anchor bar 8 is fixedly installed on the mounting plate 9. When the second concrete structure 4 is constructed, the mounting plate 9 is installed on the second concrete structure 4, and the first anchor bar 8 is anchored into the second concrete structure 4, so that the mounting plate 9 is fixedly installed on the second concrete structure 4. A fixing bolt 10 is fixedly installed on the mounting plate 9, and the fixing bolt 10 is arranged along the axial direction of the water inlet. When water flows in the water inlet, the mounting plate 9 can alleviate the scouring of the second concrete structure 4.

[0036] In this embodiment, a trash rack body 11 is installed between the mounting plates 9 on both sides of the water inlet. The trash rack body 11 is composed of at least two trash rack monomers, so that the trash rack monomers are conveniently transported to the water inlet through the water pipe 2, and the trash rack monomers are installed at the water inlet to form the trash rack body 11.

[0037] In this embodiment, connecting plates 12 are installed at both ends of the trash rack body 11, and mounting holes are formed on the connecting plates 12 at positions corresponding to the fixing bolts 10. When the trash rack body 11 is arranged at the water inlet, the fixing bolts 10 on the mounting plate 9 are passed through the mounting holes on the connecting plate 12, and nuts 18 are installed on the fixing bolts 10, so that the trash rack body 11 is fixedly installed at the water inlet.

[0038] In this embodiment, the mounting plate 9 is mounted on the water-facing surface of the second concrete structure 4, and the fixing bolts 10 on the mounting plate 9 are arranged along the axial direction of the water inlet. In this way, when the trash rack body 11 is mounted on the mounting plate 9, the trash rack body 11 is located on the water-facing side of the second concrete structure 4, and both the trash rack body 11 and the mounting plate 9 can play an anti-scouring role for the second concrete structure 4, and at this time, the fixing bolts 10 are only subjected to pressure in the axial direction and are not easily damaged.
