Description

Technical Field

[0001] The invention relates to the technical field of municipal underground pipeline layout, and in particular to a shallow buried underground pipeline structure, a construction device and a construction method thereof. Background Art

[0002] The conventional construction method of shallow buried underground pipelines is to dig a laying trench along the laying path, and then lay the armored cable at a depth of 0.7m in the laying trench. After laying the armored cable, a layer of soil needs to be set above the cable, and then a cover plate is set above the armored cable. The width of the cover plate also needs to be extended relative to the armored cable. After that, backfilling can be carried out to complete the laying of the underground pipeline. However, in this way, the method of digging the laying trench is more complicated and inefficient. However, if the laying trench is not dug, the cover plate cannot be laid, resulting in failure to meet the construction standards. Summary of the invention

[0003] In order to solve the problem that the conventional shallow buried underground pipeline construction method is too complicated, the present invention provides a shallow buried underground pipeline structure, a construction device and a construction method thereof.

[0004] The technical solution of the present invention is as follows:

[0005] A shallow buried underground pipeline structure includes multiple pipelines arranged below the surface of a soil layer, and the multiple pipelines are arranged at intervals on the same horizontal plane and in a direction perpendicular to the length direction. Chain covers are arranged above the multiple pipelines, and the chain covers are arranged below the surface of the soil layer. The multiple chain covers are arranged at intervals along the length direction of the pipelines, and intermediate covers are arranged between adjacent chain covers.

[0006] Different from the existing conventional integral cover plate, a chain cover plate is used instead, so that the cover plate can be laid out in a manner different from digging out laying grooves.

[0007] A construction device for a shallow buried underground pipeline structure, used for the above-mentioned shallow buried underground pipeline structure, and comprising a tractor, a vertical telescopic mechanism is arranged at the rear of the tractor, and the output end of the telescopic mechanism is arranged vertically downward and connected to a guide mechanism, the guide mechanism is arranged vertically, and the horizontal plane where it is located is parallel to the forward direction of the tractor, the side of the guide mechanism close to the moving direction of the tractor is a sharp end, used to dig away the soil layer, the side of the guide mechanism away from the sharp end is provided with a pipeline, and one end of the pipeline passes through the end of the guide mechanism away from the tractor, and the other end is wound on a rotating drum that can rotate;

[0008] The guiding mechanism is provided with a laying mechanism at a position higher than the pipeline, and the laying mechanism is connected to one end of the chain cover plate, and the laying mechanism includes a soil turning top plate covering the end of the chain cover plate, and the soil turning top plate can push the soil layer upwards.

[0009] The pipeline is laid under the soil layer through the guiding mechanism, and then the chain cover is arranged by the laying mechanism without digging a trench, which is more efficient and the backfilling is more convenient and quicker.

[0010] The chain cover is arranged in such a manner that the end of the chain cover fixed to the laying mechanism is staggered with the pipeline in the vertical direction, and the chain cover can be disassembled relative to the laying mechanism.

[0011] The above-mentioned soil turning top plate is arranged in such a manner that a through hole is arranged at a position higher than the chain cover plate, soil can pass through the through hole, and the surface of the soil turning top plate close to the tractor is an inclined surface.

[0012] The specific structure of the above-mentioned guiding mechanism is that the guiding mechanism includes a guiding frame, and the guiding frame includes a horizontal section and an inclined section, and the side of the inclined section close to the moving direction of the tractor is a triangular sharp surface.

[0013] The specific structure of the above-mentioned chain cover plate is that the chain cover plate includes a plurality of chain plates connected in sequence along the length direction, and the adjacent surfaces of adjacent chain plates are arc-shaped surfaces and can rotate.

[0014] In order to avoid collision with the original pipeline structure, a detection rod is provided on the side of the guide frame inclined section close to the moving direction of the tractor, and the detection rod is connected to the inclined section through an elastic telescopic structure, and can move in a direction away from the moving direction of the tractor after being compressed.

[0015] As a preferred embodiment, the elastic telescopic structure disposed at the connecting end of the detection rod and the inclined section of the guide frame includes two elastic telescopic structures on different height planes, and the elastic forces of the two elastic telescopic structures are different, so as to judge the basic shape of the collision structure and, to a certain extent, to distinguish whether the collision is with a tubular structure.

[0016] A construction method of a shallow buried underground pipeline structure construction device uses the above-mentioned shallow buried underground pipeline structure construction device and includes the following steps:

[0017] S1. Dig multiple foundation pits at intervals along the layout direction of underground pipelines;

[0018] S2, moving the tractor to the front of the foundation pit, connecting the guiding mechanism and the laying mechanism to the telescopic mechanism of the tractor, and adjusting the telescopic mechanism until the bottom of the guiding mechanism is located at a preset depth position;

[0019] S3, after passing the pipeline on the rotating drum through the guide mechanism, fix it at the position of the foundation pit, then connect the chain cover plate with the laying mechanism, and the length of the chain cover plate and the pipeline are both greater than the spacing setting of the foundation pit, and the spacing between the chain cover plate and the pipeline is set to be more than 1.5 times the thickness of the preset buffer layer;

[0020] S4, start the tractor, and move along the layout direction of the underground pipeline at the first speed, the second speed and the third speed in sequence until it reaches the next foundation pit position, and the second speed is greater than the first speed and greater than the third speed, and during this process, the unwinding speed of the rotating drum for the pipeline is in real time the same as the moving speed of the tractor;

[0021] S5, replacing the pipeline on the rotating drum at the second foundation pit position, and connecting one end of the pipeline to the first pipeline after being laid through a connector, and at the same time replacing a new chain cover;

[0022] S6. Repeat the above arrangement until the arrangement of all pipelines between foundation pits is completed;

[0023] S7. An intermediate cover plate is set between the chain cover plates of each foundation pit, and then the foundation pit is backfilled.

[0024] In order to avoid damaging the original underground pipelines during construction, if the moving distance of the detection rod away from the tractor is greater than the preset value, the operation will be stopped. If the offset angle of the detection rod is greater than the preset vertical, the operation will also be stopped.

[0025] The beneficial effects of the present invention are as follows: the present invention is a shallow buried underground pipeline structure, a construction device and a construction method thereof, which are different from the existing shallow buried underground pipeline structure. First, the original integral cover plate is replaced by a chain cover plate, and then, by setting up a construction device, the pipeline can be buried deep below the soil surface without digging trenches. The work that the staff needs to complete only requires digging a few foundation pits, and only requires connecting the pipelines and subsequent backfilling in the above-mentioned foundation pits. Moreover, in the above-mentioned structure, it can be seen that the operation can be completed by a tractor, and the staff only needs to replace the pipelines and the chain cover plates when arriving at each foundation pit position. After backfilling the foundation pit, there is no obvious difference in function from the existing underground pipeline structure, so the construction of the shallow buried underground pipeline can be completed with high efficiency.

[0041] like Figure 2-4A shallow buried underground pipeline structure shown in the figure includes a plurality of pipelines 2 arranged below the surface of a soil layer 1. The pipelines 2 may be cables, and the shallow buried depth is generally about 0.7 m. There may be some differences according to the actual scene requirements. In addition, in the above structure, the plurality of pipelines 2 are arranged at intervals on the same horizontal plane and in a direction perpendicular to the length direction. That is to say, the number of cables actually arranged also needs to be changed according to actual needs, and is not necessarily a fixed number. It should be noted that a chain cover 4 is provided above the plurality of pipelines 2. No matter how the number of pipelines 2 changes, the width of the chain cover 4 needs to be changed to cover all the pipelines 2, and the width of the chain cover 4 extends outward. One end distance to ensure that it can cover the top of the pipeline 2. It should be noted that the chain cover 4 is set below the surface of the soil layer 1 and the distance from the pipeline 2 is greater than 10 cm. Generally, a buffer layer needs to be set between the pipeline 2 and the chain cover 4 to avoid direct contact between the pipeline 2 and the chain cover 4. After that, multiple chain covers 4 are spaced along the length direction of the pipeline 2, and intermediate covers 5 are arranged between adjacent chain covers 4. Due to the influence of this construction method, the above-mentioned chain cover 4 cannot be set as a whole, so it needs to be set in sections and at the position where the spacing is generated, that is, the position where the pipeline 2 cannot be covered, the intermediate cover 5 is set to supplement it, and finally ensure that there is a cover above the pipeline 2 for protection.

[0042] The above structural design can be used to replace the conventional integral cover plate with a chain cover plate 4, so that the cover plate can be laid out in a manner different from digging out the laying groove, and the chain cover plate 4 can be bent to a certain extent, so it can be Figure 1 Arrange in the state shown.

[0043] Afterwards, it was also made public. Figure 1 The construction device for a shallow buried underground pipeline structure shown is used for the above-mentioned shallow buried underground pipeline structure and includes a tractor 10. The tractor 10 is used to provide power, and a vertical telescopic mechanism 8 is arranged at the rear of the tractor 10, and the output end of the telescopic mechanism 8 is arranged vertically downward and connected to a guide mechanism 6, so that the guide mechanism 6 can be adjusted in height to a certain extent, which is suitable for shallow buried pipelines of different depths, and the guide mechanism 6 is arranged vertically, and the horizontal plane is parallel to the forward direction of the tractor 10, that is, in the process of moving with the tractor 10, the moving path of the above-mentioned guide mechanism 6 is a straight line, and the resistance is small, and in order to further reduce this resistance, as shown in FIG. Figure 6-10 As shown, the side of the guide mechanism 6 close to the moving direction of the tractor 10 is a sharp end, specifically as shown in Fig.10The structure shown can be used to push aside the soil layer 1, and then the pipeline 2 is provided on the side of the guide mechanism 6 away from the sharp end, and one end of the pipeline 2 passes through the end of the guide mechanism 6 away from the tractor 10, and the other end is wound on a rotatable rotating drum 9. During the movement of the tractor 10, the rotating drum 9 also rotates accordingly, and the linear speed of the rotation is the same as the moving speed of the tractor 10 in real time. Therefore, the pipeline 2 can be laid in cooperation with the tractor 10, and after the laying, the soil layer 1 can cover the pipeline 2, and there is no need to carry out large-scale backfilling operations, and it is only necessary to compact the soil at the position opened by the guide mechanism 6.

[0044] And if Figure 6 As shown, the specific structure of the guide mechanism 6 is that the guide mechanism 6 includes a guide frame 61, and the guide frame 61 includes a horizontal section and an inclined section, and the side of the inclined section close to the moving direction of the tractor 10 is a triangular sharp surface, that is, Fig.10 The structure shown in the figure, and the purpose of setting the inclined section is to be able to cut the soil at different heights at the same time, that is, to avoid the problem of collapse of the side wall of the foundation pit.

[0045] Since the situation under the soil layer 1 is unclear, in order to avoid collision with the original pipeline 2 structure, a detection rod is provided on the side of the inclined section of the guide frame 61 close to the moving direction of the tractor 10, and the detection rod is connected to the inclined section through an elastic telescopic structure, and can move in the direction away from the moving direction of the tractor 10 after being compressed. Fig.11 As shown, the detection rod and the guide mechanism 6 are in the same vertical plane, and the telescopic direction is also in the vertical plane. After that, it only needs to touch a foreign object to be compressed and move, and the elastic force of the elastic telescopic structure is relatively large. Therefore, when the pressure is not satisfied, the foreign object can still be pushed to both sides and continue to move forward. However, after the pressure reaches the limit position, it is necessary to stop the machine. At this time, it may be affected by a large foreign object or collide with the original pipeline structure. The pressure condition of the elastic telescopic mechanism can be detected by setting a distance sensor to monitor the contraction condition of the elastic telescopic mechanism. Since the structure is relatively simple, it will not be repeated.

[0046] Generally speaking, if a single detection rod is under pressure, it can be basically determined that it is affected by foreign objects rather than the pipeline. However, if all the detection rods are under pressure, it can basically be determined that it is affected by the pipeline. At this time, it is necessary to shut down the machine and dig a foundation pit here.

[0047] Afterwards, since the pipeline is not necessarily arranged perpendicular to the moving direction of the tractor 10, there is also a situation where only a single detection rod is compressed. In order to better judge the above problem, Fig.11As shown, the elastic telescopic structure provided at the connecting end of the detection rod and the inclined section of the guide frame 61 includes two on different height planes, and the elastic forces of the two elastic telescopic structures are different. The basic shape of the collision structure can be judged, and to a certain extent, it can be distinguished whether it collides with a tubular structure. Since there are requirements for the buried depth of pipeline 2, the height position of the collision object can be judged to a certain extent through the above method. If it is higher or lower, only the single elastic telescopic mechanism at the corresponding position is under more severe pressure. At this time, it can be judged as non-pipeline 2. If a foreign object is collided at the corresponding height, both elastic telescopic mechanisms will be under pressure, and the curved surface of the pipeline will also affect the contraction length of the elastic telescopic mechanism. Through the above method, a certain degree of distinction can be made, and then it can be judged whether it is necessary to stop the machine to dig the foundation pit.

[0048] After the above structure is completed, only the pipeline 2 can be arranged, but a cover plate needs to be set above the pipeline 2. For this purpose, the guide mechanism 6 is provided with a laying mechanism 7 at a position higher than the pipeline 2, and the laying mechanism 7 is connected to one end of the chain cover 4, and the laying mechanism 7 includes a soil turning top plate 71 covering the upper end of the chain cover 4, and the soil turning top plate 71 can push the soil layer 1 upwards. After pushing the soil layer 1, the above-mentioned chain cover 4 can be covered here, so that the layout of the cover plate can be completed, but it is different from the conventional cover plate, such as Figure 1 As shown, due to the size of the foundation pit and the relatively long laying length of the cover plate, it can only be placed by bending and moved forward with the guide mechanism 6. For this reason, the above-mentioned chain cover plate 4 must be used.

[0049] It should be noted that if Figure 7 , 8 As shown, the specific structure of the chain cover plate 4 is that the chain cover plate 4 includes a plurality of chain plates 41 connected in sequence along the length direction, and the adjacent surfaces of adjacent chain plates 41 are arc-shaped surfaces and can rotate. The adjacent chain plates 41 are connected by connecting members 42. The chain plates 41 are prefabricated structures and can be made using the same process as existing building prefabricated blocks. In addition, the distance between adjacent foundation pits needs to be known, and the length of the chain cover plate 4 is cut accordingly.

[0050] Then it can be realized, such as Figure 1 As shown, the pipeline 2 is laid under the soil layer 1 by the guiding mechanism 6, and then the chain cover 4 is arranged by the laying mechanism 7 without digging a trench, which is more efficient and more convenient and quick to backfill. Backfilling only needs to be done at the foundation pit position, and other positions only need to be compacted.

[0051] Furthermore, the arrangement of the chain cover 4 is implemented as follows: Figure 5As shown, the end of the chain cover 4 fixed to the laying mechanism 7 is staggered with the pipeline 2 in the vertical direction, and the chain cover 4 can be disassembled relative to the laying mechanism 7. The detachable arrangement of the chain cover 4 can facilitate the replacement operation in the foundation pit, and the staggered arrangement can ensure that the space between the chain cover 4 and the pipeline 2 can be backfilled with soil, that is, the soil-turning top plate 71 will not turn up the soil between the pipeline 2 and the chain cover 4, and the soil at this position can be left in place, and then can be covered by the chain cover 4, and it will also cover the top of the pipeline 2.

[0052] As a preferred embodiment, Figure 8 As shown, the soil turning top plate 71 is arranged in such a manner that the soil turning top plate 71 is provided with a through hole 72 at a position higher than the chain cover plate 4, and soil can pass through the through hole 72, and the surface of the soil turning top plate 71 close to the tractor 10 is an inclined surface. The inclined surface facilitates soil turning, and the through hole 72 is arranged so that soil can pass through, which can allow soil to fall on the top of the chain cover plate 4 to cover it while reducing resistance.

[0053] Finally, a construction method of a shallow buried underground pipeline structure construction device is also disclosed, using the above-mentioned shallow buried underground pipeline structure construction device, and comprising the following steps:

[0054] S1. Multiple foundation pits are excavated at intervals along the layout direction of the underground pipeline 2, and the spacing length between adjacent foundation pits is inversely proportional to the layout depth of the pipeline 2. As the depth of the pipeline 2 increases, the depth of the chain cover 4 needs to be deeper while keeping the height of the chain cover 4 and its buffer layer unchanged. Accordingly, there will be more soil layers above it, so the weight is greater, and the impact on the tractor 10 will be greater. Therefore, it is necessary to minimize the length of the single laying of the chain cover 4 to avoid failure to perform normal operations;

[0055] S2, move the tractor 10 to the front of the foundation pit, connect the guide mechanism 6 and the laying mechanism 7 with the telescopic mechanism 8 of the tractor 10, and adjust the telescopic mechanism 8 until the bottom of the guide mechanism 6 is at a preset depth position;

[0056] S3, after the pipeline 2 on the rotating drum 9 passes through the guide mechanism 6 and is fixed at the position of the foundation pit, the chain cover plate 4 is connected to the laying mechanism 7, and the length of the chain cover plate 4 and the pipeline 2 are both greater than the spacing setting of the foundation pit, the spacing between the chain cover plate 4 and the pipeline 2 is set to be more than 1.5 times the thickness of the preset buffer layer, and the vertical spacing between the chain cover plate 4 and the pipeline 2 is proportional to the buried depth of the pipeline 2. When the buried depth of the pipeline 2 is greater, the pressure is greater, and accordingly, the buffer layer needs to be higher. It can be seen that the applicability of this device is excellent. Through the above method, the spacing between the chain cover plate 4 and the pipeline 2 can be freely adjusted;

[0057] S4, start the tractor 10, and move along the layout direction of the underground pipeline 2 at the first speed, the second speed and the third speed in sequence until it reaches the next foundation pit position, and the second speed is greater than the first speed and the third speed, and in this process, the unwinding speed of the rotating drum 9 on the pipeline 2 is the same as the moving speed of the tractor 10 in real time, and before leaving the foundation pit and entering the foundation pit, the speed needs to be reduced to avoid causing the collapse of the side wall of the foundation pit, and before the chassis reaches the next foundation pit, the chain cover 4 is under greater pressure, so the tractor needs to provide greater pulling force, thereby reducing the speed;

[0058] S5, replacing the pipeline 2 on the rotating drum 9 at the second foundation pit position, and connecting one end of the pipeline 2 to the first pipeline 2 after being laid through the connector 3, and at the same time replacing a new chain cover 4;

[0059] S6, repeat the above arrangement until the arrangement of all pipelines 2 between foundation pits is completed;

[0060] S7. An intermediate cover plate 5 is arranged between the chain cover plates 4 of each foundation pit, and then the foundation pit is backfilled to complete the operation.

[0061] Correspondingly, due to the existence of the detection rod, in order to avoid damaging the original underground pipeline 2 during the construction process, if the movement distance of the detection rod away from the tractor 10 is greater than a preset value, the operation is stopped; if the offset angle of the detection rod is greater than a preset value, the operation is also stopped.
