Description

Technical Field

[0001] This invention relates to the field of pump station and storage facility construction technology, and particularly to the structure and construction method of space-saving integrated pump station and storage facility. Background Technology

[0002] As urban flooding problems become increasingly severe, the requirements for flood control are constantly being raised, placing higher demands on traditional drainage systems.

[0003] Under the new requirements, traditional flood control facilities need to take into account both drainage and flood prevention as well as non-point source pollution control. As a result, a large number of projects have emerged that involve building new storage facilities near existing pumping stations or attaching storage facilities to newly built pumping stations.

[0004] There are two types of new pumping stations with attached water storage facilities. One type involves a flat layout, with both facilities constructed separately. This type requires a large land area, has a long construction period, and causes significant environmental impact during construction. The other type uses a multi-story underground structure to integrate the pumping station and water storage facilities. This type reduces the land area required, but the underground structure is deep, leading to higher costs, greater construction risks, and the need to address the issue of pumping out pressurized water during construction, which also has a significant environmental impact. Furthermore, both types require extensive engineering pile foundations or diaphragm walls, and using traditional cast-in-place construction methods contradicts the national requirements for green and low-carbon development.

[0005] Therefore, given the increasing scarcity of land resources and the trend of cities developing towards intensive, sustainable, green, and low-carbon development, how to construct pumping stations and water storage facilities with minimal land occupation, rapid construction, and low impact to solve urban flooding problems, while fully utilizing the bearing capacity of ultra-deep shafts to reduce the construction of pile foundations for pumping stations and water storage facilities, and promoting the development of cities towards intensive, sustainable, green, and low-carbon development, has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of the above-mentioned deficiencies of the prior art, the present invention provides a space-saving integrated pumping station and storage facility structure and construction method. The purpose is to achieve the construction requirements of less land occupation, fast construction and low impact, solve the problem of urban flooding, and at the same time make full use of the ultra-deep vertical bearing capacity, reduce the construction of pumping station and storage facility pile foundations, and promote the development of cities towards intensive, conservatism and green low-carbon development.

[0007] To achieve the above objectives, the present invention discloses a space-saving integrated pump station and storage facility structure, including a pump station section and a storage facility.

[0008] The pumping station is partially located underground, with the storage and regulation facilities located below it.

[0009] During construction, the storage facility is a prefabricated, assembled vertical shaft type storage facility, including a temporary section of the vertical shaft that matches the height of the pumping station, and a permanent section of the vertical shaft located below the temporary section.

[0010] The temporary section of the vertical shaft is part of the pump station;

[0011] The upper end of the permanent section of the shaft is connected to the bottom of the pump station section.

[0012] This invention also provides a construction method for a space-saving integrated pumping station storage facility structure, comprising the following steps:

[0013] Step 1: Lower the permanent section and temporary section of the prefabricated assembled vertical shaft type storage facility to the design elevation; after the permanent section and the temporary section of the vertical shaft are structurally stable, pour the bottom sealing concrete in sequence and construct the bottom slab of the water storage tank.

[0014] Step 2: After constructing the retaining piles for the pump station section and erecting horizontal supports, excavate the foundation pit for the pump station section.

[0015] Step 3: After the foundation pit is excavated to the bottom, pour the foundation layer and the main structure of the pump station. At the same time, remove all the horizontal supports and the temporary section of the shaft, and connect the main structure of the pump station with the permanent section of the shaft to form a whole.

[0016] Step 4: After the main structure of the pumping station is completed, construct the water storage tank in the regulating and storage facility, as well as the internal structure of the pumping station section, and construct the top partition of the permanent section of the vertical shaft.

[0017] Preferably, the bottom of the well is cleaned and repaired before pouring the bottom sealing concrete and constructing the bottom slab of the water storage tank.

[0018] Preferably, in step 2, one end of any of the horizontal supports is erected on the corresponding temporary section of the shaft.

[0019] Preferably, the bottom slab reinforcement of the main structure of the pump station is effectively connected to the permanent reinforcement of the shaft in the permanent section of the shaft through a reinforcement connector.

[0020] Preferably, a water-stopping measure is provided between the bottom slab reinforcement of the main structure of the pump station and the permanent section of the vertical shaft, and the water-stopping measure is used to prevent water from entering.

[0021] The beneficial effects of this invention are:

[0022] This invention fully utilizes the intensive and green characteristics of prefabricated, assembled vertical shaft-type water storage facilities to meet the construction requirements of less land occupation, faster construction, and lower impact. At the same time, it makes full use of their load-bearing capacity, reduces the construction of pile foundations for pumping stations and water storage facilities, promotes the development of cities towards intensive, sustainable, green and low-carbon development, and provides a new approach to solving urban flooding problems.

[0033] Example

[0034] like Figure 8 and Figure 9 As shown, the space-saving integrated pump station and storage facility structure includes the pump station section and the storage facility.

[0035] The pumping station is located underground, with storage facilities underneath.

[0036] During construction, the storage facility is a prefabricated, assembled vertical shaft type storage facility, including a temporary vertical shaft section 2 that matches the height of the pump station, and a permanent vertical shaft section 1 located below the temporary vertical shaft section 2.

[0037] Shaft temporary section 2 is part of the pump station;

[0038] The upper end of the permanent section 1 of the shaft is connected to the bottom of the pump station section.

[0039] This invention minimizes the area and structural depth of the pump station by incorporating some equipment into the prefabricated, assembled vertical shaft-type water storage facility. This results in a smaller footprint, faster construction speed, and less impact on the surrounding area. At the same time, it fully utilizes the load-bearing capacity of the prefabricated, assembled vertical shaft-type water storage facility, reducing the need for pile foundation construction for the pump station. This achieves the construction requirements of less land occupation, faster construction, and lower impact, thereby promoting the development of cities towards intensive, sustainable, green, and low-carbon development, and providing a new approach to solving urban flooding problems.

[0040] In practical applications, the number, location, and depth of prefabricated, assembled vertical shaft-type water storage facilities can be adjusted according to the water storage demand.

[0041] like Figures 1 to 5 As shown, the present invention also provides a construction method for a space-saving integrated pumping station storage facility structure, comprising the following steps:

[0042] Step 1: Lower the permanent section 1 and temporary section 2 of the prefabricated assembled vertical shaft type storage facility to the design elevation; after the permanent section 1 and temporary section 2 of the vertical shaft are structurally stable, pour the bottom sealing concrete 3 in sequence, and construct the bottom slab 10 of the water storage tank.

[0043] Step 2: After constructing the pump station retaining piles 5 and erecting the horizontal supports 4, excavate the foundation pit for the pump station section.

[0044] Step 3: After the foundation pit is excavated to the bottom, pour the foundation layer and the main structure 6 of the pump station. At the same time, remove all horizontal supports 4 and the temporary section 2 of the vertical shaft, and connect the main structure 6 of the pump station with the permanent section 1 of the vertical shaft into a whole.

[0045] Step 4: After the main structure 6 of the pumping station is completed, construct the water storage tank in the regulating and storage facility, as well as the internal structure of the pumping station, and construct the top partition 11 of the permanent section 1 of the vertical shaft.

[0046] In practical applications, since the storage facility is a prefabricated, assembled vertical shaft type storage facility, and the pump station facilities are placed inside the vertical shaft, the area and excavation depth of the pump station pit can be effectively reduced, thereby reducing the size and depth of the retaining piles, and reducing the size, length and number of supports. The number of horizontal supports can be reduced to no more than two out of four. Compared with conventional solutions, this will effectively optimize the amount of retaining works.

[0047] In practical applications, before pouring the bottom sealing concrete 3 and constructing the water storage tank bottom slab 10, the bottom of the well is cleaned and repaired.

[0048] In practical applications, in step 2, one end of any horizontal support 4 is erected on the corresponding temporary section 2 of the shaft.

[0049] In practical applications, one end of the horizontal support 4 can be erected on the temporary section 2 of the shaft, which can reduce the length of the corresponding horizontal support 4.

[0050] like Figure 6 and Figure 7 As shown, in practical applications, the bottom plate steel bars 9 of the main structure 6 of the pump station and the permanent steel bars 8 of the permanent section 1 of the shaft are effectively connected by steel bar connectors 7.

[0051] In practical applications, a water-stopping measure 12 is provided between the bottom plate steel reinforcement 9 of the main structure 6 of the pump station and the permanent section 1 of the vertical shaft, and waterproofing is achieved through the water-stopping measure 12.

[0052] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
