Description

Technical Field

[0001] This utility model relates to an assembly valve chamber, specifically an assembly valve chamber for PCCP, belonging to the field of exhaust valve chamber technology. Background Technology

[0002] The traditional construction process for exhaust valve chambers includes earthwork excavation, steel reinforcement fabrication, formwork installation, concrete pouring, and earthwork backfilling. Prestressed steel cylinder concrete pipe fittings refer to steel pipe fittings used in conjunction with the installation of prestressed steel cylinder concrete pipes, mainly including: closure pipes, main valve connecting pipes, elbows, tees, etc.

[0003] Traditional exhaust valve chamber construction proceeds based on pipeline excavation and installation. The main structure can only be constructed after pipeline installation and acceptance. In cases of high groundwater levels, dewatering is required first. The construction site also necessitates the availability of electricity, gas, cranes, and other essential facilities. The main structure is constructed using cast-in-place commercial concrete, but due to the inherent properties of concrete, its final strength is only 28 days. This traditional construction method is characterized by high difficulty, slow speed, and poor durability. Therefore, this paper proposes a prefabricated valve chamber for PCCP (Precast Concrete Pipeline Cylinder). Utility Model Content

[0004] This invention proposes an assembly valve chamber for PCCP to solve the problems of high construction difficulty, slow speed and poor durability in the traditional construction mode of the prior art.

[0005] This utility model is achieved through the following technical solution: an assembly valve chamber for PCCP, including a pier, a filling cavity inside the pier, a connecting groove on the top of the pier, a first sliding groove on the top of the pier, a first slider slidably connected to the inner side of the first sliding groove, and a locking block fixedly connected to the top of the first slider. By pulling the locking block with a handle, a second slider moves in the second sliding groove, and drives the locking block to lock into the locking block to complete the limiting and fixing of the locking block, thereby completing the connection and fixing of the column and the pier. Cement is injected into the filling cavity through the injection port to improve stability. This structure is convenient to assemble and disassemble while having high stability, making the overall structure safe and reliable.

[0006] A column is snapped onto the upper side of the pier. A slot is opened at the top of the column, and a second sliding groove is opened on the outer side of the column. A second slider is slidably connected to the inner side of the second sliding groove, and an interlocking block is fixedly connected to the outer side of the second slider. The pier is connected to the column through an installation plate and a steel bar connector. At the same time, the prefabricated house is sealed to the installation plate. A waterproof layer is installed inside the prefabricated house. The internal air pressure of the prefabricated house is regulated by an insulated breather, which not only improves the sealing performance but also strengthens the overall structure and improves the overall stability.

[0007] Furthermore, an installation plate is provided on the upper side of the column, and a steel bar connector is fixedly connected to the outer side of the installation plate. The steel bar connector is snapped into the inner cavity of the slot. A prefabricated panel house is fixedly connected to the top of the installation plate, and a waterproof layer is fixedly connected to the inner side of the prefabricated panel house. A large-diameter PCCP exhaust tee is detachably connected to the bottom of the prefabricated panel house, and a heat-insulating breather is fixedly connected to the top of the prefabricated panel house. The heat-insulating breather penetrates the prefabricated panel house and extends into the inner cavity of the prefabricated panel house. The prefabricated panel house and the installation plate are sealed together, and the installation of the waterproof layer can prevent groundwater from entering, which can effectively improve the stability of the overall structure.

[0008] Furthermore, a grouting port is provided on the outer side of the pier, which is connected to the filling cavity. Cement is injected into the filling cavity through the grouting port to make the structure of the pier more stable.

[0009] Furthermore, a handle is fixedly connected to the outer side of the interlocking block, and the outer side of the handle is electroplated with an anti-slip coating. The handle facilitates the lifting of the interlocking block, and the anti-slip coating prevents slipping.

[0010] Furthermore, both the column and the steel bar connector have screw holes on their outer sides, and bolts are screwed into the inner sides of the screw holes. The cooperation between the bolts and the screw holes facilitates the fixed connection between the steel bar connector and the slot.

[0011] Furthermore, a ladder is fixedly connected to the inside of the prefabricated house, and a manhole cover is installed on the top of the prefabricated house. The manhole cover is positioned corresponding to the ladder. The manhole cover is used to open and close the prefabricated house, and the ladder facilitates the entry and exit of staff.

[0012] This utility model provides an assembly valve chamber for PCCP, which has the following beneficial effects:

[0013] 1. During installation, the assembly valve chamber for PCCP is constructed by inserting the column into the connecting groove, pushing the locking block to move the first slider within the first sliding groove, causing the locking blocks to fit together and surround the column. By pulling the handle, the fitting block moves the second slider within the second sliding groove, causing the fitting block to engage with the locking block, thus completing the limiting and fixing of the locking block. This completes the connection and fixing of the column and the pier. Cement is injected into the filling cavity through the grouting port to improve stability. This structure is easy to assemble and disassemble while having high stability, making the overall structure safe and reliable.

[0014] 2. The assembly valve chamber used for PCCP connects the prefabricated panel house to the columns through the mounting plate and steel reinforcement connectors. At the same time, the prefabricated panel house is sealed to the mounting plate. The interior of the prefabricated panel house is equipped with a waterproof layer. The internal air pressure of the prefabricated panel house is regulated by the heat-insulating breather, which not only improves the sealing performance but also strengthens the overall structure and improves the overall stability.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0023] Please see Figures 1-4 This utility model embodiment provides an assembly valve chamber for PCCP, including a platform 100, a filling cavity 110 inside the platform 100, a connecting groove 111 on the top of the platform 100, a first sliding groove 120 on the top of the platform 100, a first slider 121 slidably connected to the inner side of the first sliding groove 120, and a locking block 122 fixedly connected to the top of the first slider 121.

[0024] Please refer to this carefully. Figures 1-4 A column 130 is snapped onto the upper side of the pier 100. A slot 131 is formed at the top of the column 130, and a second sliding groove 140 is formed on the outer side of the column 130. A second slider 141 is slidably connected to the inner side of the second sliding groove 140, and a fitting block 142 is fixedly connected to the outer side of the second slider 141. A filling port 112 is formed on the outer side of the pier 100, and the filling port 112 communicates with the filling cavity 110. A handle 143 is fixedly connected to the outer side of the fitting block 142, and the outer side of the handle 143 is electroplated with an anti-slip coating. During installation, the column 130 is inserted into the connecting groove 111, and the fitting block is pushed... 122 causes the first slider 121 to move within the first slide groove 120 under force, and drives the locking blocks 122 to fit together and surround the column 130. By pulling the interlocking block 142 through the handle 143, the second slider 141 moves within the second slide groove 140, and drives the interlocking block 142 to engage with the locking block 122 to complete the limiting and fixing of the locking block 122, thereby completing the connection and fixing of the column 130 and the pier 100. Cement is injected into the filling cavity 110 through the injection port 112 to improve stability. This structure is easy to assemble and disassemble while having high stability, making the overall structure safe and reliable.

[0025] For example, the traditional exhaust valve chamber main structure is constructed using a commercial concrete cast-in-place method. Due to the unique characteristics of concrete, its final setting strength is only 28 days, resulting in high construction difficulty, slow speed, and poor durability in the traditional construction method. By inserting the column 130 into the connecting groove 111, pushing the locking block 122 to make the locking block 122 fit together, and then pulling the handle 143 to move the fitting block 142, the fitting block 142 is locked into the locking block 122, thereby completing the fixed and limited positioning of the locking block 122. At this time, the locking block 122 wraps around the column 130, which can increase the stability of the connection. Moreover, this structure does not require the use of auxiliary tools for auxiliary operation, making the operation convenient and simple, and improving the efficiency of disassembly and assembly.

[0026] Please refer to this carefully. Figure 1 and Figure 2An mounting plate 200 is installed on the upper side of the column 130. A steel rebar connector 210 is fixedly connected to the outer side of the mounting plate 200, and the steel rebar connector 210 is snapped into the inner cavity of the slot 131. A precast panel house 220 is fixedly connected to the top of the mounting plate 200. A waterproof layer 221 is fixedly connected to the inner side of the precast panel house 220. A large-diameter PCCP exhaust tee 222 is detachably connected to the bottom of the precast panel house 220. A thermal breathing apparatus 230 (DN50) is fixedly connected to the top of the precast panel house 220. The thermal breathing apparatus 230 penetrates the precast panel house 220 and extends into its inner cavity. The column 130 and the steel rebar connector... Screw holes 211 are opened on the outer side of 210, and bolts 212 are screwed into the inner side of the screw holes 211. A ladder 231 is fixedly connected to the inner side of the prefabricated house 220. A manhole cover 232 is installed on the top of the prefabricated house 220, and the manhole cover 232 corresponds to the position of the ladder 231. The prefabricated house 220 is connected to the column 130 through the mounting plate 200 and the steel bar connector 210. At the same time, the prefabricated house 220 is sealed to the mounting plate 200. A waterproof layer 221 is installed inside the prefabricated house 220. The internal air pressure of the prefabricated house 220 is regulated by the heat-insulating breather 230, which not only improves the sealing performance but also strengthens the overall structure and improves the overall stability.

[0027] For example, in traditional exhaust valve chambers, gaps exist when the main structure and supporting structure are connected, resulting in poor waterproofing. Groundwater may enter the main structure through these gaps, corroding the internal structure and causing damage. By connecting the precast panel 220 to the column 130 through the mounting plate 200 and steel connector 210, and sealing the precast panel 220 to the mounting plate 200, and installing a waterproof layer 221 inside the precast panel 220, groundwater can be effectively prevented from entering, improving waterproofing and overall structural stability.

[0028] In use, this utility model involves inserting the column 130 into the connecting groove 111, pushing the locking block 122 to move the first slider 121 within the first sliding groove 120, causing the locking blocks 122 to fit together and surround the column 130. Pulling the inserting block 142 with the handle 143 causes the second slider 141 to move within the second sliding groove 140, causing the inserting block 142 to engage with the locking block 122, thus fixing and limiting the locking block 122. This completes the connection and fixation between the column 130 and the pier 100. Cement is injected into the filling cavity 110 through the injection port 112, thereby improving stability. This structure is easy to assemble and disassemble while maintaining high stability.

[0029] The prefabricated panel house 220 is connected to the column 130 via the mounting plate 200 and the steel bar connector 210. At the same time, the prefabricated panel house 220 is sealed to the mounting plate 200. A waterproof layer 221 is installed inside the prefabricated panel house 220. The internal air pressure of the prefabricated panel house 220 is regulated by the heat-insulating breather 230, which not only improves the sealing performance but also strengthens the overall structure.

[0030] It should be noted that the insulated breathing apparatus 230 mentioned in the text is existing technology that can be found. The principle is as follows: the insulated breathing apparatus 230 includes a pressure differential control breathing component and a valve chamber. The breathing component is automatically opened and closed by controlling the pressure differential. When the pressure difference between the inside and outside of the chamber is greater than the design opening pressure, the insulated breathing apparatus 230 is automatically opened, and the valve chamber inhales or exhales air. When the pressure difference between the inside and outside of the chamber is less than the design closing pressure, the insulated breathing apparatus 230 is automatically closed, and the valve chamber stops inhaling or exhaling air, and is in a heat preservation state.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
