Description

Technical Field

[0001] The present invention relates to the technical field related to pipeline construction, and in particular to a small modular bracket for pre-buried process pipelines and a construction method thereof. Background Art

[0002] The normal construction logic of CAP1000 pre-buried pipelines is to prefabricate process pipe sections, tie lower-layer steel bars, install prefabricated process pipelines, and finally tie upper-layer steel bars. Since the upper and lower-layer steel bars are tied continuously, there is not much window for installing pre-buried pipelines after the lower-layer steel bars are tied. The steel bar tying and process pipeline installation are concentrated in one time period, and there is cross-construction, which may cause pipeline pollution and installation difficulties. At the same time, since the process pipelines are equipped with some on-site welds, the welds need non-destructive testing, there are uncontrollable factors, and the on-site construction time is uncontrollable. Summary of the invention

[0003] In view of this, in order to solve the above problems, the object of the present invention is to provide a small modular bracket for pre-buried process pipelines, characterized in that it includes:

[0004] Two columns, beam, pipe clamp;

[0011] Step 1: According to the scope of the pre-buried pipelines in the construction area, according to the pipelines in the same plane or the same vertical plane, and the actual hoisting space on site, several modularizable ranges are divided, and the design coordinate points are set within the modularizable ranges;

[0012] Step 2: According to the divided modular ranges, prefabricate several pipeline segments in the workshop and assemble them in the construction area. Select a relative positioning point and coordinate system direction on any pipeline segment, corresponding to the design coordinate point, set the inflection point position on the pipeline segment, and mark it;

[0013] Step 3: placing the pipe section in step 2 on the beams of the plurality of brackets, fixing the pipe section with the pipe clamps of the plurality of brackets, adjusting the relative position of the beam relative to the two columns, and adjusting the relative position of the pipe clamp relative to the beam;

[0014] Step 4: Assemble the remaining pipeline segments with the pipeline segment in step 3 through the inflection point of the laying-out to form a modular pipeline;

[0015] Step 5: According to the size and shape of the modular pipeline, several lifting points are set on the modular pipeline, and lifting analysis is performed. When the on-site conditions are met, the modular pipeline is lifted;

[0020] Compared with the prior art, the above technical solution has the following positive effects:

[0021] Through the application of the present invention, a small modular bracket for pre-buried process pipelines and a construction method thereof are provided. The present invention utilizes the small modular installation method for pre-buried process pipelines to perform modular assembly of pipelines at an assembly site, thereby improving the construction environment, reducing or avoiding the contamination of pipelines during on-site installation, and completing the welds at the assembly site.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical contents.

[0029] like Figures 1 to 4 As shown, a small modular bracket for pre-buried process pipelines according to a preferred embodiment is shown, which includes: two columns 1, a cross beam 2, and a pipe clamp 3.

[0030] The two ends of the cross beam 2 are slidably mounted on the two upright columns 1 ; the pipe clamp 3 is arranged in a "U" shape, and the two ends of the pipe clamp 3 are slidably mounted on the cross beam 2 .

[0031] In actual use, the main pipeline 7 is placed on the cross beam 2, the cross beam 2 supports the main pipeline 7, and the pipe clamp 3 can fix the main pipeline 7 placed on the cross beam 2. The two columns 1 and the cross beam 2 are made of angle steel.

[0032] The present invention also has the following implementation modes based on the above:

[0033] Further, a small modular bracket for pre-buried process pipelines is provided, wherein a base 4 is installed at the bottom end of each column 1. Specifically, the column 1 is supported on the ground by the base 4.

[0034] Further, a small modular bracket for pre-buried process pipelines, wherein each column 1 is provided with a waist hole 5 in the longitudinal direction, and the crossbeam 2 is slidably installed in two waist holes 5 through a bolt pair. Specifically, when the bolt pair is loosened, the crossbeam 2 can slide up and down in the waist holes on the two columns 1, and when the crossbeam 2 is adjusted to a fixed position, the bolt pair is tightened.

[0035] Further, a small modular bracket for pre-buried process pipelines is provided, wherein two mounting holes are provided on the crossbeam 2, and two ends of the pipe clamp 3 are slidably mounted in the two mounting holes. Specifically, the supporting lateral position of the main pipeline 7 is adjusted by the lateral position of the pipe clamp 3 in the mounting hole.

[0036] A construction method for a small modular bracket for pre-buried process pipelines, comprising the above-mentioned small modular bracket for pre-buried process pipelines,

[0037] Step 1: According to the scope of the pre-buried pipelines in the construction area, according to the pipelines in the same plane or the same vertical plane, and the actual hoisting space on site, several modular ranges are divided, and the design coordinate points are set within the modular range; specifically, first a modular range is divided in the construction area where the pre-buried pipelines need to be buried;

[0038] Step 2: According to the divided modular ranges, prefabricate several pipeline segments 7 in the workshop and assemble them in the construction area. Select a relative positioning point and coordinate system direction on any pipeline segment 7, corresponding to the design coordinate point, set the layout inflection point position on the pipeline segment 7, and mark it; secondly, according to the modular range, set the size, shape, etc. of several pipeline segments 7, and prefabricate several pipeline segments 7 in the workshop.

[0039] Step 3: Place the pipe segment 7 in step 2 on the crossbeams 2 of several supports, fix the pipe segment 7 with the pipe clamps 3 of several supports, adjust the relative position of the crossbeam 2 to the column 1, and adjust the relative position of the pipe clamp 3 to the crossbeam 2, so as to adjust the slope and installation direction of the pipe segment 7; specifically, support the pipe segment 7 by several crossbeams 2, and fix the pipe segment 7 by the pipe clamps 3 on several crossbeams 2. When the longitudinal position of the pipe segment 7 needs to be adjusted, slide the crossbeam 2 up and down in the two waist holes 5 of the two columns 1, and when the crossbeam 2 is moved to the desired position, fix the crossbeam 2 by the bolt pair 6, so that the position of the crossbeam 2 does not change. When the transverse position of the pipe segment 7 needs to be adjusted, since the two installation holes set on the crossbeam 2 are also waist holes, move the pipe clamp 3 on the crossbeam 2 left and right, and fix the pipe clamp 3 after adjusting it to the desired transverse position, so that the transverse position of the pipe clamp 3 changes. Therefore, the pipeline section 7 can be adjusted by the crossbeam 2 and the pipe clamp 3. When the slope of the pipeline section 7 is adjusted, the transverse sections 2 supported at different positions of the pipeline section 7 can be located at different horizontal heights.

[0040] Step 4: Assemble the remaining pipe segments 7 with the pipe segment 7 in step 3 through the inflection point position of the line laying out to form a modular pipe 8; specifically, only the installation direction, slope, etc. of one pipe segment 7 need to be adjusted. When the adjustment of the pipe segment 7 is completed, the remaining pipe segments can be welded and assembled on the pipe segment 7.

[0041] Step 5: According to the size and shape of the modular pipeline 8, several lifting points are set on the modular pipeline 8, and lifting analysis is performed. When the on-site conditions are met, the modular pipeline 8 is lifted; specifically, multiple lifting points are set on the assembled modular pipeline 8, and the modular pipeline 8 is lifted according to the multiple lifting points to prevent the modular pipeline 8 from deformation.

[0042] Step 6: Place the modular pipe 8 into the modular range.

[0043] Furthermore, a construction method for a small modular bracket for pre-buried process pipelines is characterized in that in step one, a BIM model is used to analyze and divide several modularizable ranges in advance. Specifically, the BIM model is used to analyze the pipelines on the same plane in the construction area in advance, and they are divided into modular pipelines 8 in combination with the hoistable space. The welds of the modular pipelines 8 are all prefabricated welds, which expands the prefabrication depth, and the division principle can be as follows: on planes or vertical surfaces without space restrictions, the modular pipelines 8 that can be assembled are as large as possible; if there are space restrictions, such as in steel plate walls, the modular pipelines 8 that can be assembled should consider the inner width of the steel plate wall, so that the hoisting is met and the end of the pipeline is about 50mm out of the steel plate wall after the pipeline is in place to facilitate subsequent construction; box module pipelines.

[0044] Furthermore, a construction method for a small modular support for pre-buried process pipelines further includes the following step between step 4 and step 5: retesting the assembled modular pipeline as a whole to ensure that the position errors of the endpoints and the turning points of the laying out are within the range required by the design. Specifically, the accuracy of the construction is ensured by retesting.

[0045] Furthermore, a construction method of a small modular support for pre-buried process pipelines further includes the following steps after step 6: retesting and fixing the modular pipelines 8 placed in the modular range to ensure that the final installation position of the modular pipelines 8 is within the design allowable error range. Specifically, by repeatedly retesting the modular pipelines 8, displacement of the small modular pipelines 8 during casting is effectively prevented.

[0046] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
