Description

Technical Field

[0001] The present invention relates to the technical field of infrastructure, and in particular to a shock-absorbing and waterproof device for an assembled integrated pipe gallery. Background Art

[0002] A comprehensive pipeline corridor is an underground urban pipeline corridor, which is a tunnel space built underground in the city, integrating various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage, and is equipped with special inspection ports, lifting ports and monitoring systems. It implements unified planning, design, construction and management, and is an important infrastructure and "lifeline" to ensure the operation of the city.

[0003] 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.

[0004] However, ordinary integrated pipeline corridors can only withstand various ground load impacts in the short term and it is difficult to achieve long-term earthquake resistance. The structural rigidity and strength design of ordinary integrated pipeline corridors are obviously insufficient, and the waterproof effect is poor. They do not have a specific waterproof structure and there are safety hazards. This also affects the operation of the entire public municipality and brings inconvenience to residents' lives.

[0005] The plates on the top of the integrated pipeline corridor directly bear dynamic loads and static loads. The walls on both sides not only have to bear the dynamic loads and static loads of the top plates, but also have to bear the lateral loads of the side soil layers. Therefore, in order to enhance the bearing capacity of the integrated pipeline corridor and its ability to resist the impact of ground loads and prevent structural instability, the walls need to be very thick. Moreover, this structure is made by on-site casting or prefabricated parts, which requires a large amount of work, a long construction period and high construction cost. It is not conducive to the long-term promotion and use of earthquake-resistant integrated pipeline corridors, and will greatly increase construction and maintenance costs. In addition, traditional urban underground pipeline corridors have no buffering and shock-absorbing protection measures. The shaking of the pipeline during operation can easily damage the main body, reducing the service life of the pipeline. Summary of the invention

[0006] In order to solve the problems of weak structural rigidity, poor seismic resistance and waterproof performance of the integrated pipe corridor in the prior art, the present invention provides a shock-absorbing and waterproof device for an assembled integrated pipe corridor, which mainly realizes the seismic isolation effect through a shock-absorbing structure and an elastic energy-absorbing plate sliding up and down in a slideway, and improves the structural rigidity of the integrated pipe corridor by installing a plurality of reinforcement structures in the reinforcement layer to prevent the structure of the integrated pipe corridor from becoming unstable, and improves the waterproof performance of the pipe corridor by installing a waterproof board and pasting a waterproof film in the integrated pipe corridor.

[0007] The present invention provides a shock-absorbing and waterproof device for an assembled integrated pipe gallery, comprising a pipe gallery body, a reinforcement layer, a shock-absorbing structure, a support column and a surface layer, wherein a gravel load-bearing base layer is laid on the bottom of the pipe gallery body, a reinforcement layer is fixedly connected to the outer wall of the pipe gallery body, a plurality of reinforcement structures are inlaid on the inner wall of the reinforcement layer, a shock-absorbing structure is fixedly installed on the top of the reinforcement layer, support columns are fixedly installed on the left and right ends of the top of the shock-absorbing structure, a slideway is provided at a recessed portion of the side wall of each support column, a slider is slidably connected to the inner wall of the slideway, an elastic energy-absorbing plate is fixedly connected between two of the sliders, a waterproof plate is fixedly connected to the top of the elastic energy-absorbing plate, a plurality of grooves are provided on the upper surface of the waterproof plate, the waterproof plate is located below the surface layer, and backfill soil is filled around the reinforcement layer, the shock-absorbing structure and the support column;

[0008] The shock-absorbing structure is a hollow structure surrounded by an extrusion support plate and a side support plate. The upper and lower ends of the inner cavity of the shock-absorbing structure are fixedly connected to one end of a plurality of second elastic energy-absorbing rods. The other end of each of the second elastic energy-absorbing rods is connected to an arc-shaped energy-absorbing steel plate. Two of the arc-shaped energy-absorbing steel plates are directly fixedly connected to a compression spring, and a shock-absorbing spring is connected between each of the arc-shaped energy-absorbing steel plates in the horizontal direction.

[0009] As a further improvement of the present invention, the reinforcement structure includes a reinforcement shell, and the inner wall of the reinforcement shell is staggeredly connected with first reinforcement ribs and second reinforcement ribs.

[0010] As a further improvement of the present invention, a waterproof film is pasted on the inner wall of the pipe gallery body, and the waterproof film is specifically butadiene rubber.

[0011] As a further improvement of the present invention, a plurality of second sets of rods are fixedly installed on the lower surface of the elastic energy absorbing plate, a first set of rods is fixedly installed on the lower surface of the sliding block, the inner walls of the second sets of rods and the first sets of rods are both sleeved with first elastic energy absorbing rods, and the bottom of each first elastic energy absorbing rod is fixedly connected to the extrusion support plate.

[0012] As a further improvement of the present invention, the first set of rods, the second set of rods, the first elastic energy-absorbing rods and the second elastic energy-absorbing rods are all made of high-damping rubber.

[0013] As a further improvement of the present invention, a clamping plate is screwed between the two side support plates and the support column via an expansion bolt.

[0014] As a further improvement of the present invention, the extruded support plate, the side support plate, the elastic energy dissipation plate and the arc-shaped energy dissipation steel plate are all made of low-yield point energy dissipation steel plates.

[0015] As a further improvement of the present invention, the compression spring and the shock absorbing spring are both made of high-strength springs.

[0016] Beneficial effects: The present invention uses two seismic structures, a shock-absorbing structure and an elastic energy-absorbing plate that slides up and down in a slideway, to resist the vibration energy transmitted to the corridor structure by the dynamic load and static load on the ground, thereby achieving a seismic isolation effect and enhancing the bearing capacity and the ability to resist the impact of ground loads of the comprehensive corridor. At the same time, by installing a number of reinforcement structures in the reinforcement layer, the structural stiffness of the comprehensive corridor is improved to prevent the structural instability of the comprehensive corridor, thereby reducing the harm of the corridor and the personnel and objects inside the corridor caused by the load impact, which is very meaningful for the construction of underground infrastructure. The present invention installs a waterproof board and sticks a waterproof film in the comprehensive corridor, which improves the waterproof performance of the corridor in the later stage of use, reduces the maintenance cost of the underground corridor in the later stage of use to a certain extent, avoids the shortening of the service life of the underground corridor due to the impact of dynamic loads and static loads from the ground, and can prevent the corridor from being damaged by load impact and causing a series of major accidents. It has strong practicality and wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS
