[0022] The present application is further described below in conjunction with specific embodiments and drawings.
[0023] refer to Figure 1 and Figure 2 As shown, an anti-floating construction structure for underground cable pipes in municipal roads includes a cable pipe trench, in which are arranged power pipes 1, pipe clamps 2, lightning protection grounding plates 3 and lightning protection grounding electrodes 4. The power pipes 1 are made of chlorinated polyvinyl chloride (CPVC) with specifications of φ200mm (wall thickness 8.5mm) + φ110mm (wall thickness 5mm), the pipe clamps 2 and lightning protection grounding plates 3 are made of galvanized flat iron 50*5mm, and the lightning protection grounding electrodes 4 are made of angle steel L50*50*5mm.
[0024] A plurality of electric power pipes 1 are arranged in the longitudinal direction and in a lattice shape in the transverse direction. The pipe clamps 2 surround the electric power pipes 1 in the transverse direction, so that the plurality of electric power pipes 1 form a whole.
[0025] The lower part of the pipe clamp 2 is connected to the lightning protection grounding plate 3, which is arranged in the longitudinal direction. The lightning protection grounding plate 3 is set at the bottom of the pipe group of the power pipe 1 and is parallel to the power pipe 1. Specifically, one end of the pipe clamp 2 is a straight head and the other end is a right-angle head. The straight head is connected to the lightning protection grounding plate 3, and the right-angle head is connected to the lightning protection grounding electrode 4. The connection method is welding, and the three form a fixed structure.
[0026] The lightning protection grounding plate 3 is connected between the lightning protection grounding electrodes 4. The length of the lightning protection grounding plate 3 is the distance between two adjacent lightning protection grounding electrodes 4. In the present application, the spacing between two adjacent lightning protection grounding electrodes 4 is 5m, so the spacing between two adjacent pipe clamps 2 is also 5m, which can not only stabilize the connection and fix the structure, but also save costs, while meeting the effect of lightning protection grounding.
[0027] A pipe clamp 2 is arranged above each lightning protection grounding electrode 4 to ensure structural stability. The length of the lightning protection grounding electrode 4 is 2500mm, and its lower end is inserted into the soil to achieve grounding of the power pipe 1. At the same time, due to the connection between the lightning protection grounding electrode 4, the lightning protection grounding plate 3, and the pipe clamp 2, and the wrapping of the power pipe 1 by the pipe clamp 2, the power pipe 1 can be indirectly fixed in the cable pipe trench by the lightning protection grounding electrode 4, and will not float up during the later pouring process.
[0028] A pipe pillow 5 is also provided in the cable pipe trench, and the pipe pillow 5 is laterally supported between the power pipes 1. The specification of the pipe pillow 5 is DN200, and the material is modified polypropylene, which has extremely high strength, firmness, wear resistance, corrosion resistance and stability.
[0029] The pipe pillow 5 is arranged every 2.5m, and half supports are formed at both ends, and half ring grooves are arranged on the half supports to support the power pipes 1, so as to ensure that each power pipe 1 is stable and does not affect each other. At the same time, the upper and lower pipe pillows 5 form a complete wrapping support for the power pipe 1 in the middle.
[0030] The workflow of this application: The lightning protection grounding electrode 4 is injected into the soil after the cable drainage pipe trench foundation inspection groove is qualified, with a spacing of 5m. Then the lightning protection grounding plate 3 is installed along the longitudinal length of the trench, which is welded to the lightning protection grounding electrode 4, and a pipe clamp 2 is installed every 5m. The size of the pipe clamp 2 is the same as the outer size of the drainage pipe group. Overlap welding is used between the pipe clamp 2, the lightning protection grounding plate 3, and the lightning protection grounding electrode 4, and the overlap length is ≥2b (width). After the installation of the lightning protection grounding electrode 4 is completed, the foundation cushion layer is poured, and then the power drainage pipe 1 and the pipe pillow 5 are installed. The power drainage pipe 1 passes through the pipe clamp 2, and the pipe pillow 5 is installed every 2.5m to ensure that the drainage pipe gap is uniform and the positioning is secure.
[0031] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
