Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, and in particular relates to prefabricated sealed wellhead height-increasing water-saving meter wells. Background Technology

[0002] In urban water supply systems, water meter wells serve as crucial infrastructure for water meter installation and maintenance, and their performance directly impacts the stability and metering accuracy of the system. With accelerating urbanization, higher demands are being placed on water meter wells in terms of ease of installation, sealing, load-bearing capacity, and stability.

[0003] Traditional water meter wells have several shortcomings in structural design and functional implementation. In terms of installation, most employ on-site casting or monolithic structures, resulting in complex construction processes that require significant manpower, resources, and time. Furthermore, they have stringent site requirements, making them unsuitable for rapid construction and standardized building practices. Regarding sealing performance, traditional water meter wells suffer from poor sealing between the wellhead cover and the well opening, allowing rainwater, dust, and other impurities to enter the well. This leads to moisture and rust on the water meter and related equipment, affecting their normal operation and lifespan.

[0004] In terms of load-bearing capacity, traditional water meter wells lack effective reinforcement structures around them. When subjected to external forces such as vehicle crushing or ground loads, they are prone to problems such as wellhead deformation and collapse, posing significant safety hazards.

[0005] To address these issues, we offer a prefabricated sealed wellhead height-enhancing water-saving meter well. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated sealed wellhead height-enhancing water meter well. Through the cooperation of the well body and the well cover, it solves the problems of complex construction process and poor sealing performance of water meter wells in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model is a prefabricated sealed wellhead height-enhancing water meter well, including a well body. The top of the well body is fixedly connected to a well cover by bolts. A height-enhancing section one is fitted into the top of the well cover. A height-enhancing section two is fitted into the top of the height-enhancing section one. A groove is formed on the top of the well body. A protrusion fitted into the groove is integrally formed on the bottom of the well cover. Threaded holes are formed on the opposite side of the well body and the well cover. Steps are formed on the top of the inner cavities of the well cover, height-enhancing section one, and height-enhancing section two. A sealing ring is placed on the top of the step.

[0009] The present invention is further configured such that the bottom of the well body cavity and the top of the outer surface are integrally formed with reinforcing ribs, and the reinforcing ribs at the bottom of the well body cavity and the top of the outer surface form an "I"-shaped load-bearing structure, which enhances the bottom of the well body's anti-settlement ability and the top's impact resistance, making it particularly suitable for soft soil foundation environments.

[0010] The present invention is further configured such that the well body and the well cover adopt a wave-shaped design, and the waves on the surface of the well body and the well cover correspond one-to-one. The wave-shaped surfaces of the well body and the well cover form a stress-dispersing structure, reducing local deformation under concentrated loads, while increasing the surface area to improve the bonding force of concrete during pouring.

[0011] The present invention is further configured such that the inlet at the top of the manhole cover adopts a round opening design, and the top of the round opening is a raised design. The raised round opening of the manhole cover inlet guides the water flow to spread in all directions, preventing rainwater from accumulating at the manhole opening, and further improving the waterproof effect in conjunction with the sealing ring.

[0012] The present invention is further provided that the top of the inner cavity of the manhole cover and the bottom of the surface of the manhole cover are integrally formed with reinforcing ribs II. The reinforcing ribs II at the top and bottom of the inner cavity of the manhole cover enhance the bending resistance of the middle part of the manhole cover and prevent the manhole cover from collapsing under heavy load.

[0013] The present invention is further provided that the bottom of both the first and second height-increasing sections are provided with fitting grooves, and the cross-section of the fitting grooves is trapezoidal. The trapezoidal fitting grooves utilize the inclined plane self-locking principle to ensure that the multi-layer height-increasing sections fit tightly under vertical load, while facilitating disassembly and maintenance.

[0014] The present invention is further configured such that the inner walls of the first and second height-increasing sections are integrally formed with reinforcing ribs three. The reinforcing ribs three increase the rigidity of the cylinder wall and prevent the first and second height-increasing sections from lateral displacement due to wind or ground vibration at high altitudes, thus ensuring the overall structural stability.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model adopts a multi-layer prefabricated structure consisting of a well body, a well cover, and two heightening sections. Through the interlocking design of grooves and convex strips and the fixing connection with bolts, it breaks through the construction limitations of traditional on-site casting of water meter wells. The groove at the top of the well body and the convex strip at the bottom of the well cover form a precise positioning structure. With the help of circumferentially evenly distributed threaded holes and bolts, it can achieve rapid alignment and fastening. The two heightening sections adopt a trapezoidal interlocking groove nesting design, which can be flexibly combined according to the difference in ground elevation. No customized production is required, which significantly improves the adaptability of the project. This modular design not only reduces transportation costs, but also realizes standardized construction that can be installed and used immediately. It is especially suitable for scenarios that require rapid construction, such as the renovation of old residential areas and the expansion of municipal pipeline networks.

[0017] 2. This utility model constructs a three-dimensional waterproof system through a three-level sealing structure, namely the initial sealing of the convex strip and groove, the dynamic sealing of the stepped surface sealing ring, and the pressure sealing of the heightening section fitting groove. In terms of load-bearing design, the wave-shaped and reinforcing rib design of the inner and outer surfaces of the well body and the well cover forms a three-dimensional load-bearing structure, which can effectively improve its pressure resistance and deformation resistance, effectively solve the problem of deformation and collapse of traditional well bodies caused by road loads, and extend the service life of infrastructure.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5This utility model is a prefabricated sealed wellhead height-enhancing water meter well, including a well body 1. The top of the well body 1 is fixedly connected to a well cover 2 by bolts. The top of the well cover 2 is fitted with a height-enhancing section 1 3, and the top of the height-enhancing section 1 3 is fitted with a height-enhancing section 2 4. The top of the well body 1 has a groove 5. The bottom of the well cover 2 is integrally formed with a protrusion 6 that fits into the groove 5. Threaded holes 7 are opened on the opposite side of the well body 1 and the well cover 2. The top of the inner cavity of the well cover 2, the height-enhancing section 1 3 and the height-enhancing section 2 4 are all provided with steps 8, and a sealing ring is placed on the top of the step 8.

[0028] Specifically: The groove 5 at the top of the well body 1 is a ring-shaped wave design, and its depth and width match the integrally formed protrusion 6 at the bottom of the well cover 2, forming a pre-positioning structure of the male and female grooves to ensure that the well cover 2 is automatically aligned during installation; the contact surface of the groove 5 and the protrusion 6 is textured to enhance the initial connection rigidity; threaded holes 7 are opened at corresponding positions of the well body 1 and the well cover 2, and high-strength bolts are used to tighten them evenly around the circumference to form a rigid connection node; the step 8 at the top of the inner cavity of the well cover 2, the first heightening section 3, and the second heightening section 4 have the same width to form a continuous sealing base surface; after the sealing ring is placed on the step 8, compression sealing is achieved through the self-weight of the components and the external pipeline.

[0029] Example 2

[0030] Please see Figure 1-5 Based on Embodiment 1, the bottom of the inner cavity of the well body 1 and the top of the outer surface are integrally formed with reinforcing rib 19. The well body 1 and the well cover 2 adopt a wave-shaped design, and the waves on the surfaces of the well body 1 and the well cover 2 correspond one-to-one. The inlet at the top of the well cover 2 adopts a round opening design, and the top of the round opening is a convex design. The top of the inner cavity of the well cover 2 and the bottom of the surface of the well cover 2 are integrally formed with reinforcing rib 20. The bottom of the heightening section 13 and the heightening section 24 are both provided with fitting grooves, and the cross-section of the fitting grooves is trapezoidal. The inner walls of the heightening section 13 and the heightening section 24 are integrally formed with reinforcing rib 311.

[0031] Specifically: The reinforcing ribs 9 at the bottom of the inner cavity and the top of the outer surface of the well body 1 form an "I"-shaped load-bearing structure, enhancing the bottom's resistance to settlement and the top's impact resistance, making it particularly suitable for soft soil foundations. The wavy surfaces of the well body 1 and the well cover 2 form a stress-dispersing structure, reducing local deformation under concentrated loads and increasing surface area to improve the bonding force during concrete pouring. The raised round opening at the inlet of the well cover 2 guides water flow to diffuse in all directions, preventing rainwater from accumulating at the well opening. Combined with the sealing ring, this further enhances the waterproofing effect. The reinforcing ribs 10 at the top and bottom of the inner cavity of the well cover 2 enhance the bending resistance of the middle part of the well cover 2, preventing the well cover 2 from collapsing under heavy loads. The trapezoidal interlocking groove utilizes the inclined self-locking principle to ensure that the multi-layer heightening sections fit tightly under vertical loads, while also facilitating disassembly and maintenance. The reinforcing ribs 11 increase the rigidity of the cylinder wall, preventing the heightening sections 3 and 4 at high altitudes from lateral displacement due to wind or ground vibration, ensuring the overall structural stability.

[0032] The working principle of this utility model is as follows: First, the well body 1 is fixed in the pre-set pit. The well cover 2 is embedded into the groove 5 of the well body 1 through the protrusion 6. The bolt passes through the threaded hole 7 and is tightened to achieve a sealed connection between the well body 1 and the well cover 2. According to the ground elevation requirements, the first heightening section 3 and the second heightening section 4 are nested in sequence through the trapezoidal fitting groove. The inclined surface pressure and self-weight of the fitting groove form a mechanical lock. The well cover 2 and the well body 1 are initially isolated from debris through the protrusion 6 and the groove 5. The sealing ring on the step 8 surface undergoes elastic deformation under the pressure of the external pipe, filling the interface gap and preventing water and dust from entering. The trapezoidal fitting groove forms a tight fit under vertical pressure. The external load is transferred to the well body 1 through the first heightening section 3, the second heightening section 4 and the well cover 2. The wave-shaped design on the surface of the well body 1 and the reinforcing rib 9 disperse the concentrated load into uniform stress and reduce local deformation.
