Description

Technical Field

[0001] This invention relates to the field of municipal pipeline construction, specifically to a municipal pipeline protection structure and construction method. Background Technology

[0002] Municipal engineering projects typically involve the construction of numerous underground pipelines. Urban underground pipelines refer to water supply, drainage, gas, and other related facilities within a city, serving as crucial infrastructure for ensuring urban operation. Current pipeline construction methods mostly involve directly burying pipelines underground or using simple protective structures like geomembranes. This provides insufficient protection, leading to pipeline damage after a period of use. Furthermore, pipelines are prone to rupture after overhead collapses. Damaged pipelines disrupt residents' access to essential resources, and subsequent repairs are extremely inconvenient, time-consuming, and labor-intensive, consuming significant human and material resources. Summary of the Invention

[0003] The present invention aims to provide a municipal pipeline protection structure and construction method to reliably protect underground pipelines, reduce the occurrence of damage to underground pipelines, and thus extend their service life.

[0004] To solve the above technical problems, the specific solution adopted by the present invention is as follows: a municipal pipeline protection structure, including a pipeline protection component, the pipeline protection component having a top protective shell and a bottom protective shell, the bottom of the top protective shell is provided with an upper receiving groove, the top of the bottom protective shell is provided with a lower receiving groove, the upper receiving groove and the lower receiving groove together form a receiving groove for accommodating underground pipelines, and the whole composed of the top protective shell and the bottom protective shell is in the shape of a triangular prism.

[0005] Preferably, it also includes a support component, which has base blocks distributed on both sides of the bottom of the pipe protection component. Multiple support rods are fixed on each base block. The support rods are distributed along the slope of the side of the pipe protection component, and the two sets of support rods on both sides of the pipe protection component are staggered on the top of the pipe protection component.

[0006] Preferably, the top protective shell has an insulation cavity on the outer periphery of the upper receiving groove and the bottom protective shell has an insulation cavity on the outer periphery of the lower receiving groove, and the insulation cavity is filled with insulation cotton.

[0007] Preferably, the top protective housing has positioning protrusions on the lower edge of the top protective housing and on both sides of the upper receiving groove, and the bottom protective housing has positioning grooves on the upper edge of the bottom protective housing and on both sides of the lower receiving groove for the positioning protrusions to be inserted and positioned.

[0008] Preferably, one end of the bottom protective shell is provided with a connecting block and the other end is provided with a connecting hole. The two bottom protective shells can be fixedly connected by the plug-in fit of the connecting block and the connecting hole and by bolt connection.

[0009] Preferably, the bottom of the bottom protective housing is provided with a detection component, which includes a detection block fixed to the bottom of the bottom protective housing. The detection block has a track groove connected to the lower receiving groove. The track groove is provided with a detection trolley that can slide longitudinally along the pipeline protection component. The top of the detection trolley is attached to the lower edge of the underground pipeline in the lower receiving groove and a detection probe is provided. The detection probe is connected to a sonar detector set in the detection trolley.

[0010] Preferably, the detection trolley has magnetic metal strips on both sides of its body, and a control belt is provided along its longitudinal direction in the track groove. Electromagnetic blocks are provided at intervals in the middle of the control belt. The metal strips and the detection trolley fixed to the metal strips can be attracted and moved by sequentially opening and closing adjacent electromagnetic blocks.

[0012] A construction method for a municipal pipeline protection structure includes the following steps:

[0013] 1) Design the pipeline distribution according to the requirements of the underground pipeline network layout, and prefabricate pipeline protection components and support components according to the size of the underground pipeline;

[0014] 2) Dig a trench at the location where the underground pipeline will be laid. First, place the base blocks parallel to each other on both sides of the bottom of the trench and fix them. Then, place multiple bottom protective shells end to end between two base blocks. After placing the underground pipeline in the lower receiving trench, fasten the top protective shell to the underground pipeline and the bottom protective shell. Then, weld the lower ends of the support rods to the base blocks respectively and fix the upper ends of the support rods.

[0015] 3) Cover the support components with anti-corrosion mulch, then backfill and flatten the trench. Beneficial effects

[0016] 1. The present invention can provide comprehensive protection for underground pipelines through the top protective shell and the bottom protective shell. Since the top protective shell and the bottom protective shell are in the shape of regular triangular prisms and the parts in contact with the ground on both sides are inclined, they can effectively disperse the pressure from above and minimize the occurrence of underground pipeline rupture caused by the collapse of the upper part, thus providing reliable protection.

[0017] 2. The present invention can support and protect the pipeline protection component through the support component, thereby reducing the pressure on the pipeline protection component and further enhancing the protection effect on underground pipelines. Through the dual protection effect, the occurrence of pipeline damage can be greatly reduced, thereby extending the service life.

[0018] 3. This invention enables real-time detection and localized positioning inspection of underground pipelines through the internal structure of the bottom protective shell.

[0019] 4. The driving method of the detection housing of the present invention can eliminate the need for the arrangement of circuits inside the detection base block, thereby preventing circuit obstruction and reducing the difficulty of later circuit maintenance. Attached Figure Description

[0029] like Figure 1 As shown, a municipal pipeline protection structure of the present invention includes a pipeline protection component 4, a support component 1, and a detection component 2. The pipeline protection component 4 is located on the outer periphery of the underground pipeline 3, providing direct protection for the underground pipeline 3. The support component is located on the outer periphery of the pipeline protection component 4, providing support and protection for the pipeline protection component 4, reducing the pressure on the pipeline protection component 4, thereby further enhancing the protection effect on the underground pipeline 3. The detection component 2 is used for real-time monitoring of the underground pipeline 3 structure, enabling timely detection of pipeline damage and facilitating damage control. The pipeline protection component 4, support component 1, and detection component 2 are described in detail below:

[0030] Pipeline protection component 4

[0031] Pipe protection component 4 includes, for example Figure 4 The top protective housing 402 shown and as Figure 5 The bottom protective housing 401 is shown. The top protective housing 402 has a cross-section that is approximately equilateral triangular, and an upper receiving groove 410 is formed at the bottom of the top protective housing 402 along its length. The bottom protective housing 401 has a cross-section that is approximately isosceles trapezoidal, and a lower receiving groove 412 is formed at the top of the bottom protective housing 401 along its length. Both the upper receiving groove 410 and the lower receiving groove 412 are semi-circular. The top protective housing 402 and the bottom protective housing 401 are fastened together as shown. Figure 2 , 3 As shown, the upper receiving groove 410 and the lower receiving groove 412 together form a complete receiving pipe groove, through which the underground pipe 3 passes and provides comprehensive protection for the underground pipe 3. Furthermore, since the overall structure composed of the top protective shell 402 and the bottom protective shell 401 is a regular triangular prism shape, and the parts in contact with the ground on both sides are inclined surfaces, it can effectively disperse the pressure from above and minimize the possibility of the underground pipe 3 rupturing due to the collapse of the upper part, thus providing reliable protection.

[0032] To achieve the positioning and installation of the top protective housing 402 and the bottom protective housing 401, such as Figure 4 As shown, positioning protrusions 409, distributed longitudinally, are respectively provided on the lower edge of the top protective housing 402 and on both sides of the upper receiving groove 410; and as... Figure 5As shown, positioning grooves 411 are respectively provided along the upper edge of the bottom protective shell 401 and on both sides of the lower receiving groove 412, distributed longitudinally. The positioning protrusions 409 and positioning grooves 411 are both rectangular and of the same specification. They can be plugged together to fix the top protective shell 402 and the bottom protective shell 401, facilitating positioning during installation. Utilizing the triangular structure formed by the top protective shell 402 and the bottom protective shell 401, no additional fixing is required to ensure stable connection. To facilitate the docking of multiple pipe protection components 4 in the trench for laying the underground pipe 3, a detection block 205 is provided along the lower edge of the bottom protective shell 401, such as... Figure 2 As shown, two connecting blocks 405 are spaced apart on one end face of the detection base block 205, and threaded holes 406 are also provided on the outer side of the connecting blocks 405; Figure 3 As shown, two connecting holes 407 are provided at corresponding intervals on the end face of the other end of the detection base block 205, and a through hole 408 is provided on the outside of the connecting hole 407. The connecting block 405 and the connecting hole 407 are both rectangular and of corresponding specifications. After the connecting block 405 is inserted into the corresponding connecting hole 407, and the bolt passes through the through hole 408 and engages with the threaded hole 406, the two bottom protective shells 401 are fixedly connected, and the two adjacent pipe protection components 4 in the groove are fixedly connected, increasing the stability of the overall structure.

[0033] In addition, such as Figure 1-5 As shown, insulation cavities 404 are respectively provided on the outer periphery of the upper receiving groove 410 on the top protective shell 402 and on the outer periphery of the lower receiving groove 412 on the bottom protective shell 401. Insulation cavities 404 are filled with insulation cotton 403. The insulation cotton 403 can enhance the insulation effect of the underground pipe 3, thus reducing the freezing of the underground pipe 3 in winter.

[0034] Support Component 1

[0035] Still Figure 1 As shown, the support assembly 1 includes base blocks 102 located on both sides of the lower edge of the bottom protective shell 401 and support rods 101 welded and fixed to the base blocks 102. The support rods 101 on the left and right sides are respectively attached to both sides of the pipeline protection assembly 4, and the upper ends of the support rods 101 on both sides are staggered and attached to the top of the pipeline protection assembly 4. The support assembly 1 can support and protect the pipeline protection assembly 4, thereby reducing the pressure on the pipeline protection assembly 4 and further enhancing the protection effect on the underground pipeline 3.

[0036] Detection Component 2

[0037] The detection component 2 mainly includes a detection trolley 209 set in the detection base block 205 and a drive mechanism for driving the detection trolley 209 to move longitudinally along the underground pipeline 3.

[0038] The detection base block 205 has longitudinally distributed track grooves 203 inside, and the detection trolley 209 is slidably installed in the track grooves 203. Figure 6 As shown, the bottom of the inspection trolley 209 is provided with bottom rollers 212, and the side is provided with side rollers 211, corresponding to... Figure 2 As shown, a bottom slide rail 204 is provided along the lower edge of the track groove 203 for the bottom roller 212 to roll in engagement, and a side slide rail 206 is provided on the side wall of the track groove 203 for the side roller 211 to roll in engagement. The track groove 203 is connected to the lower receiving groove 412 through a guide groove 201, and as... Figure 6 and Figure 7 As shown, a sliding block 207 with a shape and specifications corresponding to the guide groove 201 is provided on the top of the inspection trolley 209. The sliding block 207 is engaged in the guide groove 201 and provides guidance for the movement of the inspection trolley 209 along the underground pipeline 3. A detection probe 208 is provided in the sliding block 207. The upper edge of the detection probe 208 faces the bottom of the underground pipeline 3, and the lower part of the detection probe 208 is connected to the sonar detector 213 installed in the inspection trolley 209.

[0039] The bottom of the bottom protective housing 401 is provided with a detection component 2. The detection component 2 includes a detection block 205 fixed to the bottom of the bottom protective housing 401. The detection block 205 has a track groove 203 connected to the lower receiving groove 412. The track groove 203 is provided with a detection trolley 209 that can slide longitudinally along the pipeline protection component 4. The top of the detection trolley 209 is attached to the lower edge of the underground pipeline 3 in the lower receiving groove 412 and a detection probe 208 is provided. The detection probe 208 is connected to a sonar detector 213 set in the detection trolley 209. The sonar detector 213 is connected to the control center display terminal for communication. The structure of the underground pipeline 3 can be monitored in real time through the sonar detector 213, so that the damage to the pipeline can be detected in time.

[0040] Drive mechanism such as Figure 5 As shown, it includes control strips 202 disposed on both sides of the track groove 203 and metal strips 210 disposed on both sides of the detection trolley 209. The control strips 202 are as follows: Figure 8As shown, the device contains spaced electromagnetic blocks 214, and the metal strip 210 is magnetic. By sequentially opening and closing adjacent electromagnetic blocks 214, the metal strip 210 can be attracted to move along the control belt 202, thereby driving the inspection trolley 209 to move along the track groove 203. This allows for comprehensive inspection of the underground pipeline 3 via the sonar detector 213 and the inspection probe 208, and facilitates easy movement to the areas requiring inspection. Real-time monitoring of the underground pipeline 3 structure enables timely detection of pipeline damage. This driving method eliminates the need for wiring within the inspection base block 205, preventing wiring obstructions and simplifying future wiring maintenance.

[0041] The construction method for the municipal pipeline protection structure described above includes the following steps:

[0042] S1. Pipeline design and preliminary preparation: Design the pipeline distribution according to the requirements of the underground pipeline network layout, block the construction road surface, demolish the road surface buildings, and prefabricate the pipeline protection component 4 and support component 1 according to the pipeline size. When prefabricating the pipeline protection component 4, it is necessary to ensure that the diameter of the upper receiving groove 410 and the lower receiving groove 412 in the top protective shell 402 and the bottom protective shell 401 is the same as the outer diameter of the underground pipeline 3, so as to ensure a good attachment and protection effect for the underground pipeline 3.

[0043] S2. Trenching: Use a breaker drill to break up the road surface, then clean up the broken debris, and then use trenching equipment to trench the ground. The depth and width of the trench should be greater than the height and width of the protective structure. After trenching, clean up the waste soil.

[0044] S3. Pipe laying operation: Place the pipe protection component 4 and the support component 1 in the trench. When laying the pipe, first place the base blocks 102 on both sides of the trench in parallel and fix them with anchor rods, etc. Then place the bottom protective shell 401 between the two base blocks 102 and control the distance between the two base blocks 102 to be the same. At the same time, multiple bottom protective shells 401 are connected end to end by the connecting blocks 405 at both ends and the connecting groove. Then use bolts to insert into the through holes 408 and screw them into the threaded holes 406 on one side of the connecting block 405, so that the bottom protective shells 401 can be connected to each other. After connection, use anchor rods and other fasteners to fix the bottom protective shells 401. Then, using a hoisting device, the underground pipe 3 is pulled into the lower receiving groove 412 on the bottom protective shell 401. Subsequently, the top protective shell 402 is moved to the top of the bottom protective shell 401 by hoisting device or manual handling, so that the positioning protrusion 409 at the bottom of the top protective shell 402 is inserted into the positioning groove 411 on the bottom protective shell 401 to complete the installation between the top protective shell 402 and the bottom protective shell 401. The left and right support rods 101 are welded and fixed to the base block 102 respectively. The top connection of the left and right support rods 101 is fixed with steel wire to achieve a reinforcement effect.

[0045] S4. Corrosion prevention and underground burial operation: Cover the support component 1 with anti-corrosion mulch film, then backfill the trench, and flatten the top after backfilling.

[0046] S5. Post-construction procedures: Remove the barriers and clear the road surface; the road will then be open to traffic.
