Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel engineering technology, specifically to a pipe device for preventing freezing damage to the water outlet of a tunnel. Background Technology
[0002] The main purpose of the drainage outlet of the central drainage ditch in the cold region railway tunnel is to prevent the drainage system from freezing, ensure smooth drainage, adapt to the special environment of the cold region, and reduce maintenance costs. It ensures the continuous and effective operation of the drainage system in extreme low temperature environments, and balances drainage demand with frost damage prevention through engineering measures to ensure the safety of tunnel structure and train operation.
[0003] The existing method for preventing frost damage to the drainage outlet of the central drainage ditch in cold-region tunnels involves planting grass and laying gravel slabs around the outlet. However, this method has limited grass coverage and height. In windy weather, cold air can easily penetrate the grass layer and reach the drainage outlet. Moreover, the grass's insulation properties are further reduced after it withers in winter. Grass growth may extend into the drainage outlet, especially during the peak growing season, which can obstruct water flow and slow down drainage. Poor drainage can cause the water level in the central ditch to rise, increasing the risk of water accumulation and freezing, which is detrimental to the normal operation of the drainage system. Furthermore, the precise construction techniques required for laying gravel slabs, the purchase of cold-resistant grass seeds, and the regular maintenance of the grass are all costly, resulting in high construction and maintenance costs.
[0004] Therefore, there is an urgent need for a frost protection device that has a fast drainage speed, is not prone to freezing, and has low construction and maintenance costs. Summary of the Invention
[0005] The purpose of this utility model is to provide a pipe device for preventing freezing damage to the outlet of a hole, so as to at least solve the problems of current outlet freezing protection devices that easily slow down the drainage speed, are prone to freezing, and have high construction and maintenance costs.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A device for preventing freezing damage to a drainage outlet pipe, comprising a pipe body;
[0008] The pipe body includes a first pipe wall and a second pipe wall, which are joined together vertically to form the pipe body.
[0009] The pipe body includes multiple horizontal sections and multiple vertical sections, with the drain outlet facing downwards, and the bottom of the pipe body does not contact the ground, forming a drop.
[0010] Furthermore, the first pipe wall includes a first horizontal portion and a first vertical portion, with the first vertical portion connected vertically downward to one end of the first horizontal portion.
[0011] Furthermore, the first vertical part includes a first upper corner, a first vertical pipe wall, and a first lower corner. The first upper corner and the first lower corner are respectively connected to the two ends of the first vertical pipe wall, and the first upper corner is connected to one end of the first horizontal part.
[0012] Furthermore, the second pipe wall includes a second horizontal portion and a second vertical portion, with the second vertical portion connected vertically downward to one end of the second horizontal portion.
[0013] Furthermore, the second vertical part includes a second upper corner, a second vertical pipe wall, and a second lower corner. The second upper corner and the second lower corner are respectively connected to the two ends of the second vertical pipe wall, and the second upper corner is connected to one end of the second horizontal part.
[0014] Furthermore, the first upper corner is located above the second upper corner.
[0015] Furthermore, the first downward corner is located below the second downward corner.
[0016] Furthermore, the length of the first vertical pipe wall is longer than the length of the second vertical pipe wall.
[0017] Furthermore, the corners of the inner wall of the pipe body are all smoothed.
[0018] Furthermore, the outer wall of the pipe body is wrapped with an insulation layer.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. This utility model provides a pipe device for preventing freezing damage to the drain outlet. The pipe body includes multiple horizontal sections and multiple vertical sections. The drain outlet is set vertically downwards, and the internal corners are smoothed to effectively prevent cold air from entering and prevent the water inside the pipe body from freezing. This does not affect the water discharge. Furthermore, the drain outlet is a certain distance from the open ditch, forming a drop that allows the water to fall freely, thus making the water flow at the drain outlet less prone to freezing.

[0032] Example:
[0033] This embodiment provides a pipe device for preventing freezing damage to the outlet of a cavern, including a pipe body, which includes a first pipe wall 1 and a second pipe wall 2. The first pipe wall 1 and the second pipe wall 2 are integrally spliced to form the pipe body, and the cross-section of the pipe body is circular.
[0034] Specifically, the drain outlet of the pipe, which is the bottom of the pipe body, is set downwards to effectively prevent cold air from flowing in. The pipe body includes multiple horizontal and multiple vertical sections, which further prevents cold air from entering and prevents the water inside the pipe body from freezing. At the same time, it does not affect the water discharge and effectively prevents the outlet from freezing. In addition, the drain outlet of the pipe is a certain distance away from the open ditch, that is, the bottom of the pipe body does not contact the ground, thus creating a drop and allowing the water to fall freely out of the pipe, further preventing the water from freezing.
[0035] The first pipe wall 1 includes a first horizontal part 11 and a first vertical part 12, with the first vertical part 12 integrally connected vertically downward to one end of the first horizontal part 11.
[0036] The first vertical section 12 includes a first upper corner 121, a first vertical tube wall 122, and a first lower corner 123. The first upper corner 121 and the first lower corner 123 are integrally connected to both ends of the first vertical tube wall 122. One end of the first upper corner 121 is integrally connected to one end of the first horizontal section 11, and the other end of the first upper corner 121 is integrally connected to the upper end of the first vertical tube wall 122. One end of the first lower corner 123 is integrally connected to the lower end of the first vertical tube wall 122, and the other end of the first lower corner 123 is suspended.
[0037] The second pipe wall 2 includes a second horizontal part 21 and a second vertical part 22, with the second vertical part 22 integrally connected vertically downward to one end of the second horizontal part 21.
[0038] The second vertical section 22 includes a second upper corner 221, a second vertical tube wall 222, and a second lower corner 223. The second upper corner 221 and the second lower corner 223 are integrally connected to both ends of the second vertical tube wall 222. One end of the second upper corner 221 is integrally connected to one end of the second horizontal section 21, and the other end of the second upper corner 221 is integrally connected to the upper end of the second vertical tube wall 222. One end of the second lower corner 223 is integrally connected to the lower end of the second vertical tube wall 222, and the other end of the second lower corner 223 is suspended.
[0039] Specifically, the first upper corner 121 is located above the second upper corner 221, and the bottom of the first upper corner 121 is flush with the top of the second upper corner 221. The first lower corner 123 is located below the second lower corner 223, and the bottom of the first lower corner 123 is flush with the bottom of the second lower corner 223.
[0040] The length of the first vertical pipe wall 122 is longer than the length of the second vertical pipe wall 222, so that the first vertical pipe wall 122 and the second vertical pipe wall 222 form a mountain shape, thereby increasing the flow of water and preventing the water from freezing.
[0041] In this embodiment, the corners of the inner wall of the pipe are all smoothed to effectively prevent cold air from entering without affecting the water discharge.
[0042] In this embodiment, the outer wall of the pipe body is wrapped with an insulation layer 3, which is made of polyurethane foam to prevent the water from freezing due to the low temperature in cold regions, so that the water can be discharged smoothly.
[0043] In this embodiment, the material and cost of the pipeline body are low, which can greatly save costs.
[0044] The installation method in this embodiment is as follows:
[0045] Adjust the length and diameter of the pipe body according to the actual situation. During installation, the bottom of the pipe body should be vertically downward and not in contact with the ground, forming a certain drop.
[0046] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
