[0035] Example 1 As mentioned in the background technology, in earthquake disasters, the most vulnerable locations of the pipe gallery are at the pipe gallery joints and the four corners of the sockets and sockets; since most of the current underground pipe galleries adopt shallow underground structures with a small burial depth, when the top of the pipe gallery is subjected to vehicle loads, explosion loads, mechanical loads, etc., it is very easy to resonate and cause brittle failure of the joints. However, the existing pipe gallery joints lack shock-absorbing measures at the sockets, sockets and corners, resulting in poor anti-seismic and anti-destruction capabilities of the pipe gallery joints.

[0036] In order to solve the above problems, that is, to protect the joints of the pipe gallery and improve their ability to resist earthquake damage, it is necessary to develop a shock-absorbing and anti-seismic device acting on the joints of the underground comprehensive pipe gallery to meet the safety needs of the underground comprehensive pipe gallery. Therefore, the present invention provides a shock-absorbing and anti-seismic device and an operating method for the joints of the underground comprehensive pipe gallery. The use of this device and the operating method can effectively solve the problem of poor earthquake damage resistance and destructive ability of the pipe gallery joints.

[0037] The present invention is further described in detail below with reference to the accompanying drawings and embodiments: like Figure 1 As shown, in this embodiment, a joint anti-seismic device for an underground integrated pipe gallery is provided, comprising: like Figure 1 As shown, the first integrated pipeline corridor 1 is a hollow structure. A hoisting machine is used to lift the first integrated pipeline corridor 1 and assemble and fix it on the top of the pipeline corridor foundation. The first integrated pipeline corridor 1 is used to form a closed chamber. The material used is high-strength reinforced concrete to protect the important internal pipelines to the greatest extent.

[0038] like Figure 1 As shown, the second integrated pipe gallery 2 is a hollow structure. A hoist is used to lift the second integrated pipe gallery 2 and assemble and fix it on the top of the pipe gallery foundation. The second pipe gallery 2 is used to form a closed chamber. The material used is high-strength reinforced concrete to protect the important internal pipelines to the greatest extent.

[0039] like Figure 1 and Figure 2 As shown, the shock absorbing assembly 3 is installed around the pipe gallery socket 23. The device is used to protect the concrete socket, socket and metal joint to prevent liquid water generated by earthquake from entering the pipe gallery cabin and causing damage to important internal lines, and to protect the interfaces and joints from being damaged by seismic waves.

[0040] The shock-absorbing component 3 includes an anti-corrosion structure, which is specifically composed of a TPO waterproof membrane 20 and a reinforced concrete 21 foundation. The relevant parameters of the foundation pit are designed according to the ground conditions and the excavation of the foundation pit is completed. The TPO waterproof membrane 20 is laid on the foundation soil, and then asphalt waterproof coating is applied on the top of the TPO waterproof membrane. Then, the foundation is constructed. The foundation is made of reinforced concrete 21, in which the concrete is made of silicate concrete with high strength and resistance to soft water corrosion, and the steel bars are ribbed steel bars.

[0041] like Figure 2 and Figure 3 As shown, the pipe gallery socket 23 includes a pipe gallery socket 31 and a pipe gallery socket 32, and the pipe gallery socket 31 and the pipe gallery socket 32 ​​are connected by a metal joint 22 located at the top corner; Figure 3 As shown, the rectangular shaded part in the figure is Figure 2 The side portion of the eagle-beak rubber waterstop 24 shown in the figure is compressed and deformed under the extrusion of the inner steel ring 25, thereby blocking the gap between the inner steel ring 25 and the pipe gallery socket 31, preventing the liquefied soil and groundwater produced by the soil from entering the cabin under the action of an earthquake and causing damage to important internal pipelines, keeping the inner cavity of the pipe gallery dry, and improving the earthquake resistance of the overall structure of the pipe gallery.

[0042] See also Figure 4 The metal joint 22 is made of high-strength stainless steel and is composed of a metal screw 52, ​​a metal gasket 50 and a hexagonal nut 51; Figure 5 As shown, nut chambers are dug at the top and bottom corners of the inner steel sleeve 25, and the metal screw 52 is extended into the interior of the corridor through the holes located at the corridor socket 31 and the corridor plug 32, and the metal gasket 50 is sleeved on the extended metal screw 52 to prevent stress concentration from damaging the concrete. Then the hexagonal nut 51 tightens the metal screw 52, ​​and the pre-tightening force is applied by the thread on the metal screw 52 and the tightening of the hexagonal nut 61 to fix the first integrated corridor 1 and the second integrated corridor 2; the position of the corridor socket 23, the way in which the metal joint 22 connects the socket and the plug is specifically as follows Figure 5 shown.

[0043] like Figure 6As shown, in this embodiment, the spring protection device 26 includes a spring 61 and a rubber gasket 60; the spring protection device 26 is connected between the inner steel ring 25 and the outer steel ring 27, and a rubber gasket 60 is provided at the bottom of the spring 61 on the outer side of the inner steel ring 25 to protect the spring 61 from damage caused by excessive lateral stress and bending moment; considering that there is a stress concentration phenomenon at the four corners, which causes greater concentrated stress, a corner spring with a larger radius and stronger elasticity is provided to protect the corners from breaking, and the top of the spring 61 is connected to the inside of the outer steel ring 27 by the rubber gasket 60 to ensure that the spring 61 does not fall off the ring wall of the outer steel ring 27; in this embodiment, several layers of rubber gaskets 60 are designed, which can not only ensure that the spring 61 does not fall off from between the inner steel ring 25 and the outer steel ring 27, but also block groundwater and underground humid air, prevent the spring 61 and the metal joint 22 from rusting and damage, and greatly extend the service life of the metal joint.

[0044] It should be noted that the springs 61 and the metal joints 22 are not limited to the specific numbers drawn in the drawings of this embodiment. Relevant construction personnel in this technical field can increase or decrease their numbers as needed, provided that the device can complete its multi-layer seismic and earthquake-resistant functions.

[0045] It can be seen that the present embodiment provides a kind of joint anti-seismic and earthquake-resistant device for underground comprehensive pipe gallery. The structure of the device is reasonably designed. Two pipe sections are connected by the anti-seismic and earthquake-resistant device. The structure is simple, which is convenient for the construction process and is beneficial to improving the overall toughness of the underground structure. TPO waterproof membrane is laid at the bottom of the pipe gallery foundation. It has excellent waterproof ability and can ensure that the liquid water generated by soil disturbance and the liquefied soil caused by the earthquake under the action of the earthquake will not enter the pipe gallery cabin through the gap at the bottom of the pipe gallery, thereby ensuring that the important pipelines inside the pipe gallery cabin are not damaged. At the same time, in the normal service process, it can ensure that the pipe gallery is in a humid underground for a long time. In the environment, the dryness of the corridor joints and the corridor cabin prevents the corrosion damage to the corridor foundation caused by groundwater and acidic, alkaline salts and chloride ions, and extends the service life of the corridor foundation and corridor interfaces; more importantly, a spring protection device is arranged between the outer steel ring and the inner steel ring, which can effectively reduce the relative displacement between the first integrated corridor and the second integrated corridor during an earthquake, and can absorb and disperse the energy of seismic waves when an earthquake occurs; it avoids structural damage and damage to internal facilities caused by earthquakes; this device not only improves the seismic performance of the corridor joints, but also ensures the safe operation of the facilities inside the corridor.

[0046] Example 2 This embodiment also provides a construction method of a joint anti-seismic device for an underground integrated pipe gallery, that is, a working principle, which specifically includes: First, the TPO waterproofing membrane 20 is laid on the compacted reinforced concrete 21, and then asphalt coating is brushed on the TPO waterproofing membrane 20, and then the reinforced concrete pipe gallery foundation 36 that has been woven and poured is installed on the waterproofing membrane by hoisting. Then, the first section of the integrated pipe gallery 1 and the second section of the integrated pipe gallery 2 are hoisted on the top of the pipe gallery foundation by a hoisting machine, and the two sections are connected by metal joints 22 and shock-absorbing components 3. The shock-absorbing components 3 block the gaps between the pipe gallery sockets 31 and the pipe gallery sockets 32 of the first integrated pipe gallery 1 and the second integrated pipe gallery 2, which plays a role in waterproofing and dustproofing, which can not only ensure the dryness of the interior of the pipe gallery, protect the internal circuit and the metal joints 22, but also prevent The moisture in the foundation soil causes corrosion damage to the metal joint 22, thereby extending the service life of the entire pipe gallery; the outer side of the outer steel ring is wrapped with a TPO waterproof membrane 20 to prevent the steel rings, namely the outer steel ring 27 and the inner steel ring 25, from oxidation and rust, thereby extending the service life of the device; when an earthquake occurs, since the spring 61 of the spring protection device 26 has extremely strong elasticity, it can greatly absorb the energy of the seismic wave and play a shock-absorbing role, thereby ensuring that the pipe gallery joint as a whole is in its original position to the maximum extent, so that it does not generate a large displacement load that causes the metal joint and the concrete at the pipe gallery bearing and socket to break, and ensures the normal operation of the internal important pipelines, thereby providing maximum guarantee for the rescue work in the earthquake-stricken areas.

[0047] In summary, the present invention provides a joint anti-seismic device and operation method for an underground comprehensive pipe gallery, which has the following advantages over existing anti-seismic measures: First, by designing an anti-seismic and earthquake-resistant device for underground integrated pipe gallery joints including a shock-absorbing component, the stability and safety of the pipe gallery joints in earthquakes are effectively improved. The outer steel collar and the inner steel collar in the shock-absorbing component are connected to enhance the structural strength, while the spring protection device can absorb and disperse the energy of seismic waves during an earthquake through a combination of springs and rubber washers, significantly reducing the relative displacement between the first integrated pipe gallery and the second integrated pipe gallery, thereby protecting the integrity of the pipe gallery structure and the safety of internal facilities. Furthermore, the setting of the top angle spring enhances the stability of the joint when it is subjected to lateral force or torsional force, making the anti-seismic and earthquake-resistant effect more comprehensive. The shock-absorbing components are carefully arranged around the pipe gallery socket to ensure the anti-seismic ability of the joint in all directions. At the same time, the introduction of the metal joint increases the connection strength and stability of the joint, making it easier to install and maintain; the nut compartment design at the top angle inside the inner steel collar and the specific structure of the metal joint (including metal screws, hexagonal nuts and metal washers) further enhance the reliability and convenience of the connection. In addition, the addition of anti-corrosion structure extends the service life of the device. The combination of reinforced concrete and TPO waterproof membrane not only provides good anti-corrosion performance, but also enhances the waterproof effect, protecting the internal facilities and spring protection devices from erosion by the external environment. The eagle-beak rubber waterstop installed at the socket of the corridor effectively prevents the infiltration of groundwater or rainwater, ensuring a dry environment inside the corridor. Finally, the operating method provided details the installation of the shock-absorbing component and the shock-absorbing principle during an earthquake, making the device easier to use in practical applications and able to give full play to its anti-seismic and earthquake-resistant effects. In summary, the device has achieved remarkable technical effects in improving the anti-seismic and earthquake-resistant capabilities of underground integrated corridor joints, ensuring the safety of corridor structures, and extending service life.

[0048] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes changes, replacements and other implementation methods that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention.
