Description

Technical Field

[0001] The present invention relates to the technical field of inspection wells, and in particular to an assembled and pressed modular inspection well. Background Art

[0002] Inspection wells are urban underground infrastructure, mainly used for municipal drainage and sewage disposal, and are widely used in various shopping malls and residential construction projects. They are generally located at pipeline intersections, bends, places where pipe diameters or slopes change, and at certain intervals on straight pipe sections to facilitate regular inspection of ancillary structures.

[0003] Traditional inspection wells mostly use on-site masonry or concrete pouring technology, which has disadvantages such as long construction period, high labor intensity for workers, and susceptibility to weather influences. At the same time, their structure is easily affected by foundation settlement and sewage corrosion, leading to leakage, damage and other problems, and high subsequent maintenance costs.

[0004] Driven by technological advancements, the concept of prefabrication and assembly is gradually being applied to municipal engineering projects, leading to the emergence of modular manholes with prefabrication and on-site assembly. These manholes are broken down into standardized modules, which are then assembled into a complete manhole structure using specific connection methods. Compared to traditional manholes, modular manholes with prefabrication and on-site assembly significantly shorten construction timelines and minimize the impact of construction on the surrounding environment. Their modular design allows for flexible assembly to meet diverse drainage needs, improving their applicability.

[0005] However, when existing modular safety inspection wells are built, the contact surfaces of the two adjacent inspection well modules are flat, making the gap between the two modules a straight seam. Due to factors such as the impact of water flow and the settlement of the foundation, cracks or loosening are very likely to occur at the connection, thereby providing a channel for odor to overflow, or the odor in the well is directly discharged through the drain port of the manhole cover, seriously affecting the surrounding environment and endangering the health of residents. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0024] See also Figures 1 to 6 The present invention provides an assembled pressed modular inspection well, comprising a well cover 1, a well seat 2, a first assembly cylinder 3, a second assembly cylinder 4 and an assembled drainage accessory 5, wherein the second assembly cylinder 4 is assembled on the top of the well seat 2, the first assembly cylinder 3 is assembled on the top of the second assembly cylinder 4, the well cover 1 is assembled on the top of the first assembly cylinder 3, and the assembled drainage accessory 5 comprises a pre-embedded mounting part 51, a positioning bolt 52, a guide disc 53 and a water trap 54; the pre-embedded mounting part 51 is assembled on the inner wall of the first assembly cylinder 3, the positioning bolt 52 is fixedly connected to the pre-embedded mounting part 51 and is located on one side of the pre-embedded mounting part 51, the guide disc 53 is close to the positioning bolt 52 and is located on one side of the positioning bolt 52, and the water trap 54 is assembled at the bottom of the guide disc 53.

[0025] In an embodiment of the present invention, the well seat matches the bottom of the second assembly cylinder 4 and is connected by a card-sealed structure to form a tight connection structure to ensure overall stability. The first assembly cylinder 3 and the second assembly cylinder 4 are card-sealed to form the cylinder body of the inspection well. The well cover 1 covers the cylinder body to prevent pedestrians or foreign objects from falling into the well. The assembled drainage accessories 5 are one-way conduction, which can achieve drainage of municipal roads when it rains. It is water-sealed at ordinary times to prevent odor leakage in the well. Among them, the embedded mounting part 51 is embedded during the casting production of the first assembly cylinder 3, exposing one end of the positioning bolt 52. The positioning bolt 52 is set to assemble the guide disc 53. Positioning and fixing are carried out. There are multiple second assembly cylinders 4, and the number is selected for assembly according to the required cylinder requirements. Specifically, when it rains, rainwater from the municipal road surface flows into the guide disc 53 through the drain port on the manhole cover 1, and is guided by the guide disc 53 and flows into the water trap 54. The water trap 54 then discharges the rainwater into the manhole. The setting of the water trap 54 will form a water seal therein after drainage. Normally, the water trap 54 is sealed by the water seal to prevent the odor in the well from flowing back through the water trap 54 and overflowing the manhole cover 1, forming a single-direction conduction, thereby solving the problem of odor overflow in traditional assembled inspection wells, affecting the surrounding environment and endangering the health of residents.

[0026] Furthermore, the guide disc 53 includes a disc body 531 and a fixing rod 532 . The disc body 531 has a mounting groove 533 . The mounting groove 533 is located on one side of the disc body 531 . The fixing rod 532 is assembled on the disc body 531 and is located in the mounting groove 533 .

[0027] In this embodiment of the present invention, the disc body 531 is integrally injection-molded from high-strength, corrosion-resistant polypropylene (PP) engineering plastic. It exhibits excellent acid, alkali, and aging resistance, enabling long-term, stable operation in complex underground environments. The disc body 531 is shaped like an inverted funnel, wide at the top and narrow at the bottom, facilitating rapid collection and channeling of rainwater toward the trap 54. Its outer diameter matches the inner diameter of the first assembly cylinder 3. The mounting groove 533 provides a mounting location for the fixing rod 532, which is made of stainless steel and possesses excellent strength and rust resistance. When the disc body 531 is assembled into the embedded mounting member 51, the through-hole on the disc body 531 is aligned with the positioning pin 52. The disc body 531 is then placed and pressed, forcing the positioning pin 52 through the disc body 531. The fixing rod 532 then inserts into the positioning pin 52, securing the disc body 531.

[0028] Furthermore, the fixing rod 532 includes a plug 5321 and a spring 5322 . The spring 5322 is fixedly connected to the disc body 531 and is located in the mounting groove 533 . The plug 5321 is fixedly connected to the spring 5322 and is located on one side of the spring 5322 .

[0029] In the embodiment of the present invention, when assembling the embedded mounting part 51, the through hole on the disc body 531 is aligned with the positioning bolt 52, the disc body 531 is placed and pressed, and when the positioning bolt 52 initially enters the disc body 531, the positioning bolt 52 squeezes the plug 5321 and compresses the spring 5322. When the positioning bolt 52 passes through the disc body 531, at this time, the through hole on the positioning bolt 52 is flush with the plug 5321, and the spring 5322 is reset and pushes the fixing rod 532 to insert into the positioning bolt 52, thereby realizing the assembly and fixation of the disc body 531. The plug 5321 is hemispherical on the side away from the spring 5322.

[0030] Furthermore, the guide disc 53 further includes a lifting rod 534 . The lifting rod 534 is fixedly connected to the disc body 531 and is located on one side of the disc body 531 .

[0031] In the embodiment of the present invention, the lifting rod 534 is made of stainless steel, which facilitates the pulling out of the disc body 531 during subsequent routine maintenance and inspection of the inspection well, thereby improving practicality.

[0032] Furthermore, the water trap 54 includes an S-shaped pipe 541, a drain pipe 542 and a clamp 543. The S-shaped pipe 541 is assembled at the bottom of the disc body 531, and the clamp 543 is arranged on the outer wall of the S-shaped pipe 541. The drain pipe 542 is connected to the S-shaped pipe 541 and is located at the end of the S-shaped pipe 541 away from the disc body 531.

[0033] In this embodiment of the present invention, the S-bend 541 and the drain pipe 542 are both made of high-density polyethylene (HDPE) and manufactured integrally through a hot-pressing process. They exhibit excellent chemical and impact resistance, and can withstand the pressure and temperature fluctuations found in complex underground environments. The clamp 543, which has the same inner diameter as the drain outlet at the bottom of the disc body 531, is made of 304 stainless steel and has a semi-circular ring structure. Its inner wall is provided with a non-slip rubber pad. The clamp 543 is secured by two stainless steel bolts, which are galvanized for rust prevention. During tightening, the rubber pads tightly fit the S-bend 541, enhancing friction between the clamp 543 and the S-bend 541, preventing displacement, and preventing damage to the S-bend 541 caused by direct metal contact. The disc body 531 directs rainwater into the S-bend 541, which then drains into the cylinder through the drain pipe 542.

[0034] Furthermore, the second assembly cylinder 4 includes a snap-in block 41, a triangular protrusion 42, a snap-in groove 43 and a triangular groove 44.

[0035] In an embodiment of the present invention, the second assembly cylinder 4 and the first assembly cylinder 3 are both made of cast concrete. The design of the clamping block 41, the triangular protrusion 42, the clamping groove 43 and the triangular groove 44 adds a triangular structure on the basis of the traditional clamping structure, so that the second assembly cylinder 4 and the first assembly cylinder 3 are more stable and sealed after assembly. The edges of the clamping groove 43 and the triangular groove 44 are both provided with dense EPDM rubber sealing strips to further improve the sealing of the connection and prevent groundwater from seeping into the well body.

[0036] Furthermore, the manhole cover 1 includes a manhole cover body 11, a mounting seat 12, a pressure ring 13 and a sealing ring 14. The mounting seat 12 is assembled on the top of the first assembly cylinder 3, the pressure ring 13 is fixedly arranged on the side of the mounting seat 12 away from the first assembly cylinder 3, and the sealing ring 14 is arranged on the end of the pressure ring 13 away from the mounting seat 12. The manhole cover body 11 is assembled on the top of the mounting seat 12.

[0037] In an embodiment of the present invention, the manhole cover body 11 is made of high-strength ductile iron and has anti-slip stripes on the surface, which can effectively prevent pedestrians from slipping. The sealing retaining ring 14 cooperates with the top of the first assembly cylinder 3 to achieve a good sealing effect, preventing odor from being emitted and debris from falling into the well. The outer dimensions of the manhole cover body 11 are precisely matched with the top opening of the first assembly cylinder 3. The mounting seat 12 provides an installation place for the manhole cover body 11, the pressure ring 13 and the sealing retaining ring 14. The pressure ring 13 is made of alloy steel, which is heat-treated and strengthened after forging. It is fixed to the side of the mounting seat 12 away from the first assembly cylinder 3 by welding, which can evenly disperse the pressure from the manhole cover body 11, avoid local stress concentration, and extend the service life of the manhole cover body 11.
