Description

Technical Field

[0001] This utility model relates to the field of gas pressure regulating cabinet construction technology, and in particular to a special foundation for assembled gas pressure regulating cabinets. Background Technology

[0002] Gas pressure regulating cabinets are important facilities in urban gas pipeline transmission and distribution systems.

[0003] Currently, the foundations of gas pressure regulating cabinets are generally fabricated on-site, with brick or cast-in-place concrete structures, which are non-standard, inconsistent, unstable, unsafe, and unsightly.

[0004] However, since the installation of gas pressure regulating cabinets must be carried out simultaneously with the laying of underground gas pipelines, the following drawbacks exist in the actual construction process:

[0005] 1) First, lay underground gas and then position and install the gas pressure regulating cabinet. It is difficult to compact, level and stabilize the equipment foundation according to the foundation structure design requirements.

[0006] 2) The process of first casting the concrete equipment foundation, then laying the underground pipes, and finally installing the gas pressure regulating cabinet often results in discrepancies in the positions of the underground gas pipeline, the gas pressure regulating cabinet, and the equipment foundation, making it difficult to accurately locate them.

[0007] All of the above phenomena may lead to unstable installation of the gas pressure regulating cabinet. Since it mainly relies on the support connection between the underground gas pipe and the gas pressure regulating cabinet, the gas pipeline may be subjected to shear stress due to inaccurate positioning. Under long-term stress, this may lead to safety accidents such as pipeline leakage and equipment settlement.

[0008] Furthermore, since the foundations of existing gas pressure regulating cabinets are generally fabricated on-site, with brick or cast-in-place concrete structures, all of these problems exist, and there are currently no effective solutions or technical measures.

[0009] Therefore, how to avoid the safety hazards in the above-mentioned on-site construction, ensure the safe operation of gas pressure regulating cabinets and underground gas pipelines, meet the safety requirements of urban lifelines, and facilitate on-site installation has become a technical problem that urgently needs to be solved by those skilled in the art.

[0020] The tubular well wall is divided into two symmetrical sides according to the midline position in the length or width direction;

[0021] The height of each of the aforementioned side sections of the non-adjustable well wall assembly, and the cross-section of each of the aforementioned well wall splicing units, are all U-shaped.

[0022] Preferably, each of the pre-embedded plugs is a cylinder made of ductile iron, pre-embedded in the corresponding well wall splicing unit, or pre-embedded in the height-unadjustable assembled well wall.

[0044] The outer diameter of each pre-embedded plug 4 is 10 mm smaller than the inner diameter of the corresponding slot 5.

[0045] This utility model adopts prefabricated installation technology and utilizes the modular design principle of reinforced concrete equipment foundation splicing. The foundation of the gas pressure regulating cabinet 7 is prefabricated and assembled through prefabricated base plate 1, prefabricated top plate 2, and tubular well wall 3 set between the prefabricated base plate 1 and prefabricated top plate 2. Before installation, sufficiently large pre-reserved holes 6 for installation are reserved on the prefabricated base plate 1 and prefabricated top plate 2 according to the size of the gas pressure regulating cabinet 7. The equipment foundation is pre-constructed through prefabricated structure, which facilitates the stability and safety of the equipment foundation structure. Then, the underground gas pipeline is laid and connected to the gas pressure regulating cabinet 7 to ensure that the weight of the gas pressure regulating cabinet 7 is borne by the equipment foundation and the gas pipeline is basically not under stress, thus ensuring safety.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, the cross-sections of the precast base plate 1, the precast top plate 2, and the tubular well wall 3 are all rectangular;

[0047] The tubular well wall 3 is divided into two symmetrical sides according to the midline position in the length or width direction;

[0048] The height of each side of the assembled well wall 31 is not adjustable, and the cross-section of each well wall splicing unit 321 is U-shaped.

[0049] In some embodiments, each pre-embedded plug-in 4 is a cylinder made of ductile iron, and one end of the pre-embedded plug-in 4 is a cylindrical fixing structure with a normal extension in the corresponding well wall splicing unit 321 or in the height-unadjustable assembly well wall 31. The corresponding slots 5 are all plug-in structures.

[0050] In some embodiments, the inner diameter of each slot 5 is 50 mm, and the outer diameter of the corresponding pre-embedded plug 4 inserted into the slot 5 is 40 mm.

[0051] In some embodiments, pre-reserved holes 6 are provided at the center of both the precast base plate 1 and the precast top plate 2.

[0052] In some embodiments, the height-unadjustable assembled well wall 31 is located at the boundary between the ground and the underground.

[0053] In some embodiments, a gas pressure regulating cabinet 7 is installed on the prefabricated top slab 2;

[0054] The length and width of the precast top plate 2 are greater than the length and width of the gas pressure regulating cabinet 7, and are the same as the length and width of the steel base 71 of the gas pressure regulating cabinet 7;

[0058] The following are the key points in the specific implementation of this utility model:

[0059] 1. Modular manufacturing is carried out in advance, and concrete is prefabricated according to standard dimensions. It can be mass-produced. The prefabricated bottom plate 1, prefabricated top plate 2, bottom plate 1 and top plate 2 are all left with rectangular holes. The well wall 31 and all well wall splicing units 321 are not adjustable.

[0060] 2. When installing the gas pressure regulating cabinet 7, calculate the dimensions of the height-adjustable assembly well wall 32 according to the required depth of the pipeline on site, determine the required quantity of well wall splicing units 321, then collect them from the warehouse, and finally assemble and install them on site.

[0061] III. On-site installation steps include: first, installing the precast base plate 1, then assembling the height-adjustable assembly well wall 32, and finally installing the precast top plate 2. The operation is convenient, simple and efficient.

[0062] 4. Lay the underground gas pipe to the reserved hole 6 in the precast base plate 1, install the pipe through the reserved hole 6, and then install and position the gas pressure regulating cabinet 7. After completing the installation inspection and acceptance.

[0063] After applying this utility model, in the construction of the gas pressure regulating cabinet 7, the equipment foundation can be prefabricated in batches, and on-site assembly (similar to building blocks) and positioning are more convenient and faster, resulting in a stable and aesthetically pleasing equipment foundation installation. The connection and positioning between the gas pipeline and the gas pressure regulating cabinet are precise and easy to install. The gas pipeline does not bear the weight of the pressure regulating equipment, ensuring safe operation.

[0064] This utility model is applicable to the installation of gas pressure regulating cabinet equipment in urban gas pipeline transmission and distribution systems. The prefabricated assembly structure facilitates mass production, improves construction and installation efficiency, enhances the safety and stability of equipment installation, meets the safety requirements of urban lifelines, and has broad application prospects.
