Description

Technical Field

[0001] The utility model relates to the technical field of coal-fired power generation, and more specifically to an overall relocation structure of a fire station in an expansion project of a coal-fired power plant. Background Art

[0002] A fire station at a coal-fired power plant is a building equipped with fire trucks, firefighting equipment and manned by firefighters. It is also a place for firefighters to live, study and train, and a base for firefighting, duty and fire command. Large coal-fired power plants with a single unit capacity of 300MW or above should have a fire station. Its main function is to protect the firefighting of the enterprise and to assist the society as a supplement. It is an important functional department in fire prevention and rescue in power plants. If there is a government-built fire station around the power plant and the fire truck can reach the fire scene within 5 minutes, the management of the fire station built by the government can be entrusted to it, and there is no need to set up a fire station inside the power plant.

[0003] The construction of fire stations at coal-fired power plants requires significant investment and maintenance costs, prompting construction companies to exercise caution when making design decisions. For coal-fired power plants with existing fire stations, expansion projects often face conflicts with existing structures due to the impact of the existing fire station on the overall layout. Existing fire stations are often demolished and rebuilt elsewhere, generating significant construction waste and wasting human and material resources. New fire station decoration, renovations, and ancillary facilities all require redesign, procurement, and construction. This model has proven to be time-consuming, environmentally unfriendly, and economically uneconomical.

[0004] Therefore, it is necessary to develop an overall relocation structure for the fire station in the coal-fired power plant expansion project. Utility Model Content

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned background technology and to provide an overall relocation structure of a fire station in an expansion project of a coal-fired power plant.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a fire station overall relocation structure for a coal-fired power plant expansion project, characterized by comprising an original site, an intermediate rotation area, and a new site, wherein the original site and the intermediate rotation area are connected by a first track surface, and the intermediate rotation area and the new site are connected by a second track surface;

[0007] The fire station is set up at the original site, and the fire station can be moved to the new site along the first track surface, the middle rotation area, and the second track surface in sequence.

[0008] In the above technical solution, the first rail pavement and the second rail pavement are both paved with steel plates, and limiting devices are installed on the steel plates.

[0009] In the above technical solution, the steel plate is 20 mm thick.

[0010] In the above technical solution, an integral tray is provided at the column base at the bottom of the fire station, and a moving device is provided under the integral tray.

[0011] In the above technical solution, the limiting device adopts channel steel, which is set every 2 meters and connected to the overall pallet through a rigid connector.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1) Compared with the conventional demolition and new construction method, the utility model keeps all kinds of decoration and facilities in the fire station building intact, which not only saves construction time, is economical and environmentally friendly, but also effectively reduces the generation and emission of construction waste during the construction process.

[0014] 2) For reconstruction and expansion projects, the utility model adopts the overall migration layout structure in engineering construction to establish a full life cycle concept, which complies with the requirements of "encouraging full use of the original structure" and "preventing large-scale demolition and construction, advocating the use of existing resources, and encouraging the preservation, repair and reinforcement of existing buildings."

[0015] 3) According to calculations, the construction investment cost required for the overall rotation migration using the utility model is about half of the cost of demolition and new construction, which saves construction investment costs and has significant economic benefits.

[0016] 4) The construction period affects the overall construction target progress of the project. With the adoption of the present invention, the construction period is about 1 / 3-1 / 2 of the demolition and new construction plan, which can greatly save the construction period.

[0017] 5) The use of this new type of fire station is more low-carbon and environmentally friendly; making good use of existing buildings will be one of the important options; there is a broad market space in power plants, industrial mines, industrial heritage protection, etc.; from the perspective of sustainable development, the use of this new type of fire station to relocate the entire fire station can greatly reduce construction waste, and the use of existing buildings is also a measure to reduce carbon emissions.

[0018] 6) The existing buildings have cultural value to the enterprise. The use of the utility model to relocate the fire station as a whole can retain the decoration and style of the existing buildings, which has both social and cultural value and economic and practical value.

[0023] The following detailed description of the implementation of the present invention is provided in conjunction with the accompanying drawings, which do not limit the present invention and are merely examples. The advantages of the present invention will become clearer and easier to understand through the description.

[0024] As shown in the figure, a fire station overall relocation structure for a coal-fired power plant expansion project is characterized by comprising an original site 100, an intermediate rotation area 200, and a new site 300. The original site 100 and the intermediate rotation area 200 are connected by a first rail surface 410, and the intermediate rotation area 200 and the new site 300 are connected by a second rail surface 420.

[0025] The fire station 500 is set at the original site 100, and the fire station 500 can be moved to the new site 300 along the first track surface 410, the middle rotation area 200, and the second track surface 420 in sequence.

[0026] Steel plates 430 are laid on both the first track pavement 410 and the second track pavement 420 , and a limiting device 440 is installed on the steel plates 430 .

[0027] The steel plate is 20 mm thick.

[0028] An integral tray 600 is provided on the column foot 510 at the bottom of the fire station 500 , and a moving device 610 is provided under the integral tray 600 .

[0029] The limiting device 440 is made of channel steel and is set every 2 meters. It is connected to the overall pallet 600 through a rigid connector.

[0030] The limiting device 440 is mainly used for lateral limitation when the fire station 500 is translated, to prevent the translation route from changing direction and to ensure that the building moves in a straight line during translation.

[0031] In actual use, first, the zero-meter floor wall and columns of the fire station 500 are cut off at the original site 100, and the water and electricity pipelines and other connections with the fire station 500 are cut off at the same time; an integral tray 600 is built at the column foot 510 at the bottom of the fire station 500, and a mobile device 610 is set under the integral tray 600. After the underground part of the fire station 500 is disconnected from the upper main structure of the fire station 500, the upper main structure of the fire station 500 is rotated as a whole to the required angle by the mobile device using the axial rotation method.

[0032] The fire station 500 needs to be moved on stable ground, so a stable track needs to be set up between the original site 100 and the intermediate rotation area 200; after the steel plate 430 of the first track pavement 410 is laid, a limit device 440 is installed on the steel plate 430; a combination of traction or pushing is used to move the fire station 500 smoothly.

[0033] After the fire station 500 is moved to the middle rotation area 200, it is rotated to the required angle using the same method, that is, rotated to be parallel to the new location 300 before it can continue to move horizontally to the new location 300.

[0034] A stable track is also set between the middle rotation area 200 and the new site 300. After the steel plate 430 of the second track pavement 420 is laid, a limit device 440 is installed on the steel plate 430; a translation scheme combining traction or pushing is adopted to allow the fire station 500 to be transferred smoothly.

[0035] Before Fire Station 500 is put into place, foundation construction is carried out at the new site 300 according to the original design foundation drawings; Fire Station 500 is lowered into place by jacks, and the connection between the frame columns and the foundation is restored, generally using direct steel bar connection or steel-clad connection; accordingly, the reserved interfaces such as water supply and drainage pipes, fire protection pipes, electrical lines, etc. are connected and arranged with the interfaces of the fire station 500 body; and the overall relocation of the fire station is completed.

[0036] Example

[0037] like Figure 1 As shown in the figure, taking the expansion of a 2×1000MW coal-fired power plant as an example, the existing fire station 500 is located in the boiler room area of ​​the power plant expansion, which affects the construction project and needs to be moved to the new site 300. The main building of the original fire station 500 is a frame structure with three floors above ground and a total height of 14.8m. The design service life is 50 years. The building plan is rectangular, 48.6m long and 20m wide. The ground floor area of ​​fire station 500 is 986m 2 , with a total construction area of ​​3113m 2 The building height is 12.15m; there is a strip foundation under the column, with 4 rows of independent columns, 11 columns in each row, and a total of 44 columns; the total weight of Fire Station 500 is about 3572t.

[0038] The method for relocating the fire station as a whole includes the following steps:

[0039] Step 1: Rotate the whole body at the original location:

[0040] Before Fire Station 500 can be rotated and moved as a whole, all first-floor frame columns must be severed to separate the building from its original foundation. Roller assemblies must be installed on each column, and the column bases must be reinforced with horizontal and vertical supports to ensure sufficient strength to withstand stress and strain. Using an axial rotation method, the fire station 500 must be rotated clockwise around its center at 100° to an appropriate angle α (α can be 30°). During the rotation, no significant displacement occurs. Under the influence of the rotational force, the rotational speed must meet regulatory requirements, with a displacement rate of no more than 60 mm per minute in the arc.

[0041] Step 2, first orbital translation:

[0042] The first track surface 410 is a newly poured reinforced concrete pavement. A 20 mm thick steel plate 430 is laid on the first track surface 410, and a limit device 440 is installed on the steel plate 430. A translation scheme using traction, jacking, or a combination of traction and jacking is adopted, and the limit device 440 is used to limit the movement direction of the fire station 500. During translation, each roller is arranged perpendicular to the translation direction and is translated for the first time through the first track surface 410 to the intermediate rotation zone 200.

[0043] Step 3, intermediate secondary rotation:

[0044] In the middle rotation area 200, the fire station 500 is rotated counterclockwise by an appropriate angle β (β can be 30°) using an axis rotation method.

[0045] Step 4, second orbital translation:

[0046] The second track pavement 420 is a newly poured reinforced concrete pavement. A 20 mm thick steel plate 430 is laid on the second track pavement 420. A limit device 440 is installed on the steel plate 430. The fire station 500 is moved to the new location 300 by traction or jacking or a combination of traction and jacking.

[0047] Step 5: After the fire station 500 is moved to the new location 300, the connection between the frame columns and the foundation is restored, and the interfaces of the reserved water supply and drainage pipes, fire protection pipes, electrical lines, etc. are connected to the interfaces of the fire station 500 to complete the overall relocation of the fire station.

[0048] Before fire station 500 is moved to the new site 300, the foundation construction of the new site 300 must be completed, including strip foundations, foundation columns, and foundation beams.

[0049] To sum up, the utility model not only saves investment but also greatly shortens the construction period. It is green, low-carbon and environmentally friendly, has high economic and practical value, and achieves good engineering application effects.

[0050] Other parts not described belong to the prior art.
