Description

Technical Field

[0001] The invention belongs to the field of underground infrastructure, and in particular relates to a structure that helps to increase the bearing capacity and shock absorption effect of an underground pipe gallery. Background Art

[0002] The construction of comprehensive pipe corridors is being vigorously carried out, and the areas reached by comprehensive pipe corridors will become more and more extensive. Underground comprehensive pipe corridors play an important role in meeting the basic needs of people's livelihood and improving the comprehensive carrying capacity of cities, reducing the cost of multiple road renovations and the maintenance costs of engineering pipelines. The integrity of the road surface and the durability of various pipelines are maintained, which facilitates the laying, addition, reduction, maintenance and daily management of various pipelines. In addition, the pipelines are buried together to reduce the contradiction between overhead lines and greening. However, ordinary integrated pipe corridors can only withstand various ground load impacts in the short term and it is difficult to achieve long-term earthquake resistance. The top plates directly bear dynamic loads and static loads, and the walls on both sides must not only bear the dynamic loads and static loads of the top plates, but also bear the lateral loads of the side soil layers. Therefore, in order to enhance the bearing capacity of the integrated pipe corridor and the ability to resist ground load impacts and prevent structural instability, the walls need to be set very thick. Moreover, this structure is made by on-site casting or prefabricated parts, with a large amount of work, a long construction period and high construction cost, which is not conducive to the long-term promotion and use of earthquake-resistant integrated pipe corridors and will greatly increase construction and maintenance costs. Therefore, it is very important to build an earthquake-resistant structure that is conducive to eliminating the impact of ground loads on the pipe corridor. In order to resist the dynamic loads and static loads from the ground, it is very important to form a complete earthquake-resistant protection structure to avoid the phenomenon that the ground load causes local stress increase on the pipe corridor and is unfavorable to the structure.

[0003] At present, the ability of the pipeline corridor to resist load needs to be improved. It can only guarantee the effect of resisting load under normal natural conditions. For dealing with emergencies (such as earthquakes, explosions and other disasters), the structural stiffness and strength design are obviously insufficient, and there will be hidden dangers such as pipeline scattering and structural collapse. This not only increases the subsequent maintenance costs, but also affects the operation of the entire public municipality, bringing inconvenience to residents' lives. Some pipeline corridor seismic protection structures in the existing technology have many shortcomings, such as being not conducive to the long-term construction of underground comprehensive pipeline corridors, or imperfect and unreasonable functional design. Some devices cannot guarantee long-term durability and are sometimes prone to failure. Some structural designs are relatively complex and some are too expensive. Therefore, it is very important to build a reasonable seismic protection structure that eliminates the impact of the ground on the pipeline corridor load. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the present invention provides a structure that helps to increase the bearing capacity and shock absorption effect of an underground pipeline corridor. The present invention can form a complete seismic protection structure for the underground pipeline corridor, can significantly increase the bearing capacity of the corridor and the ability to resist load damage, significantly increase the bearing capacity and shock absorption capacity of the underground pipeline corridor structure, and can prevent accidents caused by damage to the pipeline corridor by load impact.
