Technical Field
[0001] This utility model belongs to the field of gas valve wells, specifically a combined reinforced concrete precast component structure for urban gas valve wells. Background Technology
[0002] Urban gas valve wells are an indispensable component of gas transmission and distribution systems, primarily used for the installation and maintenance of gas pipeline valves and other related equipment. Currently, most urban gas valve wells utilize traditional brick masonry structures. While brick-built valve wells were common in the past, they have several drawbacks, especially under the high standards of modern urban gas systems, where their limitations have become increasingly apparent.
[0003] The construction period for brick-built valve wells is long and the construction process is complex, requiring a large amount of manual labor, resulting in low construction efficiency. Secondly, the strength and durability of brick structures are poor, and cracks and water seepage are prone to occur after long-term use, affecting the sealing and safety of the valve well. In addition, brick-built valve wells have poor seismic performance and are prone to collapse during natural disasters such as earthquakes, posing a significant safety hazard. Furthermore, the maintenance and repair of brick-built valve wells are relatively difficult, especially when it is necessary to replace or repair internal equipment, which often requires the removal of part of the well body, increasing maintenance costs and time.
[0004] To address the problems raised in the background art, those skilled in the art have proposed a combined precast reinforced concrete structure for urban gas valve wells. Utility Model Content

Detailed Implementation
[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0027] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This utility model provides a combined reinforced concrete precast component urban gas valve well structure, including an integral well wall 1, with pipe grooves 2 on both sides of the integral well wall 1. The pipe grooves 2 are "U" shaped, and a fixing sleeve 3 is fixedly installed inside the pipe grooves 2.
[0028] The lower side of the integrated well wall 1 is provided with a base 4, and the upper side of the base 4 is provided with an annular slot 5. The integrated well wall 1 extends into the annular slot 5 and slides therewith. The upper side of the integrated well wall 1 is slidably provided with a well cover 6.
[0029] Furthermore, the base 4 has an inner cavity 7, within which a sliding column 8 is slidably mounted. An arc-shaped wedge 9 is fixedly installed at one end of the sliding column 8. An inclined surface 10 is provided on the side of the arc-shaped wedge 9 extending out of the inner cavity 7. A return spring 11 is sleeved on the outer side of the sliding column 8. The two ends of the return spring 11 are connected to the side wall of the arc-shaped wedge 9 and the inner side wall of the base 4, respectively. An annular groove 12 is provided on the circumferential side of the integrated well wall 1. The arc-shaped wedge 9 extends into the annular groove 12 and slides within it. Through the arc-shaped wedge 9, during installation, the integrated well wall 1 is lifted... When the device is inserted into the annular slot 5 on the upper side of the base 4, the integrated well wall 1 first contacts the inclined surface 10 of the arc-shaped wedge 9, squeezing the arc-shaped wedge 9 to both sides. When the integrated well wall 1 is inserted into the base 4, the arc-shaped wedge 9 and the outer annular groove 12 of the integrated well wall 1 are in a horizontal state. The arc-shaped wedge 9 is driven by the force of the return spring 11 to insert into the annular groove 12. At this time, the horizontal surface of the arc-shaped wedge 9 contacts the horizontal surface of the annular groove 12, thereby achieving the locking and fixing of the integrated well wall 1, thus achieving the rapid fixing and installation of the integrated well wall 1.
[0030] Preferably, a fixing plate 15 is fixedly installed on the periphery of the integrated well wall 1 and the base 4. The upper surface of the fixing plate 15 is provided with a hook hole 16, which facilitates the hoisting and installation of the base 4 and the integrated well wall 1.
[0031] As can be seen from the above, during the installation process, the base 4 is first hoisted into the well chamber of the bag installation using hoisting equipment, and then the integrated well wall 1 is hoisted into the well chamber. During the installation process, when the integrated well wall 1 is inserted into the annular slot 5 on the upper side of the base 4 using hoisting equipment, the integrated well wall 1 first contacts the inclined surface 10 of the arc-shaped wedge 9 and squeezes the arc-shaped wedge 9 to both sides. When the integrated well wall 1 is inserted into the base 4, at this time, when the arc-shaped wedge 9 and the outer annular groove 12 of the integrated well wall 1 are in a horizontal state, the arc-shaped wedge 9 is driven by the force of the return spring 11 to insert into the annular groove 12, thereby realizing the rapid fixed installation of the integrated well wall 1.
[0032] Example 2: Based on Example 1, an annular plate 13 is fixedly installed in the inner cavity 7 of the base 4. A number of evenly distributed balls 14 are rotatably arranged on the upper surface of the annular plate 13. The balls 14 are in contact with the lower surface of the annular wedge. The balls 14 can reduce the frictional resistance of the arc wedge 9 during its movement, making it easier to drive the arc wedge 9 to move and improving the installation efficiency of the equipment.
[0033] Furthermore, the upper surface of the manhole cover 6 is provided with several evenly distributed anti-slip textures 17, and a buckle block 18 is fixedly installed on the upper side of the manhole cover 6. A through groove 19 is opened on the upper side of the buckle block 18. The manhole cover 6 can play a protective role, and the anti-slip textures 17 can enhance the anti-slip effect of the device. The buckle block 18 and the through groove 19 can facilitate the quick lifting and installation of the manhole cover 6.
[0034] Preferably, a pull plate 20 is fixedly installed on the side wall of the sliding column 8 that does not extend into the inner cavity 7. The pull plate 20 allows the sliding column 8 to be pulled quickly when disassembly is required, thereby causing the arc-shaped wedge 9 to separate from the annular groove 12, which facilitates the quick disassembly of the well wall and the base 4 and improves the maintenance efficiency of the device.
[0035] As can be seen from the above, during the installation process, the ball bearings 14 can reduce the frictional resistance of the arc-shaped wedge 9 during its movement, making it easier to move the arc-shaped wedge 9 and improving the installation efficiency of the equipment. The manhole cover 6 can provide protection, and the anti-slip texture 17 can enhance the anti-slip effect of the device. The buckle block 18 and through groove 19 can facilitate the quick lifting and installation of the manhole cover 6.
[0036] When it is necessary to quickly disassemble and repair the well wall and base 4, the sliding column 8 can be pulled to both sides to drive the arc-shaped wedge 9 to slide out of the annular groove 12, release the locking and fixing of the integrated well wall 1, and then lift the integrated well wall 1 again by the lifting device to improve the maintenance efficiency of the device.
