The long-distance pipeline without convex point should be provided with air valves every 1.0 km. The reasonable structure of the air valve well is related to the cost and progress of the project.
[0003] The patent with the patent number ZL2023209880497 applied by the patent applicant on April 27, 2023 discloses a pier type air valve well, which can effectively reduce the ground occupation, material consumption and construction period. However, in actual construction, the pier is made of concrete by on-site pouring, and the prefabricated well body is made of concrete by prefabrication. After the pier is solidified, the prefabricated well body is installed on the top of the pier. Since the prefabricated well body only serves to accommodate the air valve and meet the requirements of the maintenance personnel working in the well, it does not have any load-bearing and reinforcing functions, and therefore there is still room for further simplification.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] like Figures 1 to 6 As shown, this embodiment discloses an easy-to-install lightweight air valve well, including a retaining block 2, a precast cushion layer 13, and a well body 1.
[0026] The anchor block 2 is constructed by on-site casting of concrete and is used to fix the water supply pipeline 300. The precast subbase is also made of precast concrete, with several welded anchors 6 embedded in its top surface. A through hole is formed in the center of the anchor block 6 for the tee branch pipe 301 of the water supply pipeline 300 to pass through. The welded anchors 6 serve as the installation foundation for fixing the well body 1. They are evenly distributed in a circle around the center of the through hole, with a total of 4 anchors. The well body 1 is precast from steel plate. An eccentric well opening 1.2 is set at the top, and an upward-extending connection port 1.3 is set at the center of the bottom. A well cover 5 is installed at the well opening 1.2 as an entrance and exit for maintenance personnel. The connecting flange at the top of the connection port 1.3 is used to install the air valve 100 and the valve 200.
[0027] The advantages of using a steel well body 1 are as follows: It significantly reduces the permanent footprint of the air valve well; moreover, the steel well body 1 is lighter (for example, a DN500 air valve well with a height of 3.0m weighs approximately 2200kg, while a concrete well weighs approximately 40t, a weight reduction of 94.5%). The base foundation rests on the pipe and the encasing concrete, making it less prone to settlement or tipping due to foundation issues. Furthermore, the steel well body 1 has lower construction costs, significantly reducing the amount of concrete poured (for example, a DN500 air valve well with a height of 3.0m costs approximately 20,000 RMB for a steel well and approximately 16,000 RMB for a concrete well; however, the concrete requires a 28-day curing period, increasing construction time and labor costs by approximately 10,000 RMB). Construction is convenient and quick; after the concrete pier 2 encasing the pipe at the bottom is poured, the steel well body 1 can be directly installed onto the precast foundation, saving the time of pouring the well body 1 and ensuring installation quality.
[0028] The precast pad 13 is fixedly installed on the top surface of the pier 2, ensuring that the through hole in its center is coaxial with the tee branch pipe 301. The bottom of the well body 1 is welded to the welding anchor 6. As a preferred example, an equal number of welding plates 1.1 are welded to the bottom edge of the well body 1, and each welding plate 1.1 is fixedly connected to the corresponding welding anchor 6 by welding.
[0029] The height of the connecting flange 1.4 at the top of the connection port 1.3 is less than the height of the branch flange 302 at the top of the tee branch pipe 301, and a sealing sleeve 3 is installed between the two. The sealing sleeve 3 forms a seal to prevent water leakage.
[0030] In order for the well body 1 to be installed correctly, the inner diameter of the connecting flange 1.4 must be larger than the outer diameter of the branch flange 302. Therefore, if Figure 4 and 5 As shown, in a preferred embodiment, the sealing sleeve 3 has an inwardly extending top skirt 3.2 and an outwardly extending bottom skirt 3.1. The top skirt 3.2 is sealed and installed on the top surface of the branch flange 302 via a top pressure ring 12, and the bottom skirt 3.1 is sealed and installed on the top surface of the connecting flange 1.4 via a bottom pressure ring 11. A valve 200 and an air valve 100 are also installed on the top of the top pressure ring 12, thus enabling the integral connection of multiple components through a single set of connectors.
[0031] To better accommodate flange structures of different sizes, as a preferred example, the sealing sleeve 3 is made of rubber or a heat-shrinkable component. Heat-shrinkable components require heating at the top to shrink to the size of the branch flange 302 for connection. The sealing sleeve 3, using the material in this example, can be installed without special machining into a specific shape, making it simple and easy to install.
[0032] In order to quickly locate and install the well body 1, as a preferred example, the welding anchor 6 is provided with a positioning column 6.1, and the welding plate 1.1 is provided with a positioning hole capable of matching the positioning column 6.1. When the lower well body 1 is positioned, the positioning column 6.1 is aligned with the positioning hole, so that the well body 1 and the prefabricated cushion are positioned and installed.
[0033] Since the air valve well will leak after failure, causing excessive water accumulation in the well to submerge the devices in the well, in order to avoid damage to the devices in the well due to immersion in water, as a preferred example, the application also includes a water storage bucket 4 arranged on one side of the pier 2. According to actual needs, the volume of the water storage bucket 4 can be selected in the range of 500-2000L. The bottom of the water storage bucket 4 is arranged in the same plane as the bottom of the pier 2, and the installation space of the water storage bucket 4 can be reserved when excavating the foundation pit. The main functions of the water storage bucket 4 are as follows: first, to avoid excessive water accumulation in the well to affect the service life of the device and to gain time for maintenance. Second, to store the leakage water to avoid direct discharge, and the stored water can be used for other purposes, reducing the waste of water resources.
[0034] The water storage bucket 4 is connected with a water pipe 10, an air pipe 8 and a water taking pipe 9. The water pipe 10 is also connected to the well body 1, and the air pipe 8 is also connected to the exhaust pipe 7 at the top of the well body 1. The bottom of the water taking pipe 9 is about 5cm away from the bottom of the water storage bucket 10. After water leakage occurs in the well body 1, as the water level rises, the accumulated water will enter the water storage bucket 4 through the water pipe 10, and the air in the water storage bucket 4 will be discharged into the exhaust pipe 7 through the air pipe 8 at the top, and finally discharged into the atmosphere.
[0035] As a preferred example, the top of the water taking pipe 9 is higher than the well mouth 1.2 of the well body 1, and a cover is installed. The purpose of the water taking pipe 9 is to facilitate water taking in the later stage, so as to be used for other purposes, for example, when the water pipeline 300 passes through farmland or forest land, the stored water in the water storage bucket 4 can be used for irrigation of the surrounding farmland.
[0036] As a preferred example, the water pipe 10 is arranged at a height less than the flange of the air valve 100, and the end of the water pipe 10 extending into the water storage bucket 4 is arranged at a height less than the end of the air pipe 8 extending into the water storage bucket 4. This arrangement can prevent the height of the accumulated water in the well from exceeding the height of the branch pipe flange 302 after water leakage occurs in the well, thereby avoiding the situation that the devices in the well are immersed, and playing a protective role.
