AI Technical Summary
In areas with frozen soil and loose soil, cable protection pipes may shift due to frost heave or settlement, causing the cable and equipment terminals to bear significant stress and posing a risk of unstable connections.
The system adopts a combination structure of cable protection pipe, mounting bracket and foundation embedded parts. The foundation embedded parts are arranged horizontally in the equipment foundation. The mounting bracket is fixed on the embedded parts. The lower part of the bracket is a square frame connected to a portal frame. The cable protection pipe is fixed in the portal frame. The size of the bracket is larger than the bending radius of the cable protection pipe to ensure the stability of the relative position of the cable and the equipment terminal.
Under conditions of soil frost heave or settlement, the relative position of the cable protection pipe and the equipment terminal remains unchanged, avoiding additional stress, ensuring a safe and reliable connection between the cable and the equipment terminal, and improving the reliability of the project operation.

Description
TECHNICAL FIELD
[0001] The utility model belongs to cable protection pipe support technical field, especially be related to a cable protection pipe installation structure of applicability frozen soil and loose soil. BACKGROUND
[0002] The frozen soil phenomenon exists universally in the northern region of China, and the frozen soil depth is generally large, often exceeding the laying depth of the cable protection pipe laid in the soil. The repeated occurrence of soil frost heaving and thawing phenomenon can cause large displacement of the cable protection pipe. In loose soil areas, the cable protection pipe often settles with the soil due to the loose soil itself or the phenomenon that the backfilling soil is not compacted in place during construction. Due to the above two phenomena, the cable protection pipe is displaced. When this situation occurs at the equipment and cable connection end, the cable protection pipe displacement often causes the cable in the cable protection pipe to bear a large stress, which is transmitted to the equipment connection end, causing the connection end to bear a large stress, and even causing the cable and equipment connection end to be pulled apart, which poses a great risk to the normal operation of the project. SUMMARY
[0003] The utility model aims at solving the problem of displacement of the equipment end cable protection pipe caused by repeated soil frost heaving or loose soil, and provides a cable protection pipe installation structure suitable for frozen soil and loose soil to ensure that the connection between the cable and the equipment connection end does not bear additional stress caused by external influences, and to ensure the safe and reliable connection of the cable and the equipment connection end.
[0004] The utility model provides a cable protection pipe installation structure suitable for frozen soil and loose soil, which comprises a cable protection pipe, a mounting bracket and a foundation embedded part. The foundation embedded part is arranged horizontally and embedded in the equipment foundation. The embedding depth of the foundation embedded part is determined according to the embedding depth of the cable protection pipe. The mounting bracket is fixedly installed on the foundation embedded part at the equipment end. The lower part of the mounting bracket is a square frame. The outer end of the square frame is fixedly connected with a vertical door-shaped frame. The end of the cable protection pipe extends into the hollow position of the door-shaped frame, and the periphery is fixedly connected with the door-shaped frame by welding.
[0005] Further, the size of the mounting bracket extending out of the equipment foundation is greater than the bending radius of the cable protection pipe.
[0006] The utility model discloses can guarantee the cable protection tube that lays in the soil in the case where the soil frost heaving or uneven settlement phenomenon occurs, the relative position of cable protection tube and equipment wiring end remains unchanged, and then guarantee the connection of cable and equipment wiring end does not bear the additional stress of external influence, guarantees the safe and reliable connection of cable and equipment wiring end. The utility model discloses simple and convenient to install, clear structure, high reliability, wide application scene is applicable to all kinds of projects, can effectively improve the reliability of engineering operation. BRIEF DESCRIPTION OF DRAWINGS
[0007] Figure 1 A kind of cable protection tube installation structure suitable for frozen soil and loose soil quality;
[0008] Figure 2 It is A view.
[0009] In the drawing, the following marks are used: 1-cable protection tube;2-installation support;3-foundation embedded part;4-equipment foundation;5-equipment support. DETAILED DESCRIPTION
[0010] In order to better understand the purpose, structure and function of the utility model, the following will be described in further detail with reference to the drawings.
[0011] Referring to Figure 1 And Figure 2 , the cable protection tube installation structure suitable for frozen soil and loose soil quality includes cable protection tube 1, installation support 2 and foundation embedded part 3, and the foundation embedded part 3 can adopt [100 channel steel with a length of 350 mm, arranged transversely, embedded in the equipment foundation 4, and the embedding depth of the foundation embedded part 3 is determined according to the embedding depth of the cable protection tube 1. The installation support 2 is fixedly installed on the foundation embedded part 3 at the equipment end in a welded manner, and the installation support 2 can adopt L30x4 angle steel, the lower part is a square frame, and the outer end is welded to form a vertical door-shaped frame. The cable protection tube end extends to the hollow position of the door-shaped frame, and is welded and fixed around the door-shaped frame. The size of the installation support 2 extending out of the equipment foundation 4 should be greater than the bending radius of the cable protection tube 1, and the size of the support can be adjusted according to the number and specification arrangement of the cable protection tube. The equipment foundation 4 is provided with an equipment support 5 for installation. The cable protection tube is firmly welded on the installation support 2, and when the soil frost heaving or uneven settlement phenomenon occurs, the relative position of the cable protection tube and the support can be kept unchanged, and then the relative position of the cable protection tube and the equipment wiring end can be kept unchanged, so that the cable laid in the cable protection tube and the connection of the equipment wiring end do not bear the additional stress caused by the influence of soil frost heaving or uneven settlement, and the safe and reliable connection of the cable and the equipment wiring end is guaranteed.
