Description

Technical Field

[0001] The utility model belongs to the technical field of trench backfilling, in particular to a pipeline excavation trench layered backfilling quality control device. Background Art

[0002] Backfilling during pipeline laying refers to the process of filling the soil around the pipeline back to its original position to make the ground flat again after the pipeline is laid. The quality of backfilling directly affects the service life and drainage effect of the pipeline, so the backfilling requirements are very important.

[0003] Among them, the layered backfilling of pipeline trenches is a key quality control factor in trench backfilling construction, which mainly guarantees the quality of road backfilling and ensures that the compaction of the roadbed meets the design requirements. The current common backfilling control method is to use a layer control scale at two points in a certain section or post a layered backfill sticker on the structure to control the section in layers.

[0004] When performing backfill work for laying drainage pipes, ensure the quality and stability of the backfill layer. The quality of the backfill work determines whether the drainage pipe can operate and be used normally. Among them, the utility model patent with authorization announcement number CN217204137U discloses a trench layered backfill control tool, which ensures a highly consistent and flat backfill surface through wire rope cross-surface control. However, the above-mentioned device only accurately controls the vicinity of a specific cross position of the wire rope. In different pipeline trenches, the dimensions corresponding to the trench need to be re-planned, which not only increases the cost of use, but also reduces the efficiency to a certain extent. In order to facilitate the control of the consistency of the backfill surface height during the backfill process, this application document provides a pipeline excavation trench layered backfill quality control device.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0029] See also Figure 1-6 As shown, the utility model is a pipeline excavation trench layered backfill quality control device, comprising an adjusting rod 1, a folding rod 2, an anchor rod 3, a vertical rod 4, and a positioning plate 5. The unfolded length of the folding rod 2 is greater than the length of the adjusting rod 1. The outer wall of the anchor rod 3 is engraved with a first scale line. The adjusting rod 1 is arranged flush with the folding rod 2 as a whole and is detachably fixedly connected. The adjusting rod 1 is flush with one end of the folding rod 2, and a conical block 8 is respectively arranged at the flush ends of the adjusting rod 1 and the folding rod 2. The conical block 8 is inserted into the side wall of the foundation pit 13 when in use for positioning the ends of the adjusting rod 1 and the folding rod 2. The anchor rod 3 vertically passes through the adjusting rod 1 and is fixed by two first nuts 6, and the anchor rod 3 is adjustable in the fixed position in the length direction of the adjusting rod 1. The vertical rod 4 vertically passes through the folding rod 2 and is fixed by two second nuts 7, and the vertical rod 4 is adjustable in the fixed position in the length direction of the folding rod 2. The positioning plate 5 is installed and fixed at the lower end of the vertical rod 4. Both ends of the vertical rod 4 are provided with threaded sections, and the positioning plate 5 is provided with threaded holes adapted to the threaded sections. This arrangement allows the vertical rod 4 and the positioning plate 5 to be quickly assembled into a whole, thereby improving construction efficiency. The positioning plate 5 is a rectangular plate structure, and its lower end can be aligned with the first scale line of the anchor rod 3, so as to facilitate the measurement of the distance from the soil to the lower end of the positioning plate 5 and determine the height of the soil to be filled. The adjusting rod 1, folding rod 2, anchor rod 3, vertical rod 4 and positioning plate 5 of the utility model can be disassembled into independent components, which can be quickly packaged and installed, and do not take up a lot of space during transportation, thereby saving costs to a certain extent.

[0030] The detachable fixed connection between the adjusting rod 1 and the folding rod 2 is specifically that a guide slot 9 and a guide slider 10 that cooperate with each other are fixed on the opposite sides of the adjusting rod 1 and the folding rod 2. The adjusting rod 1 and the folding rod 2 are fixed at one end aligned by a bolt and nut 11 that penetrates.

[0031] The adjusting rod 1 is a rectangular frame structure. The folding rod 2 includes a first U-shaped frame 21 and a second U-shaped frame 22 with openings arranged opposite to each other. The upper end surfaces of the first U-shaped frame 21 and the second U-shaped frame 22 are connected as a whole by at least two hinges 23.

[0032] The second scale line is engraved on the upper surface of the adjusting rod 1. The third scale line is engraved on the upper surface of the first U-shaped frame 21 and the second U-shaped frame 22. The second scale line and the third scale line are provided to facilitate observation of the distance between the anchor rod 3 and the vertical rod 4 and the side wall of the foundation pit 13.

[0033] Among them, a plurality of binding holes 51 are provided on the positioning plate 5. A plurality of pull ropes 12 are tied between two adjacent positioning plates 5. When the pull rope 12 is straightened, its bottom is flush with the bottom surface of the positioning plate 5. After the landfill is completed, the pull rope 12 can be driven to move by moving the vertical rod 4. When the pull rope 12 moves, the flatness of the backfill soil can be seen. At the same time, during the movement of the pull rope 12, the protruding soil can be pushed to a certain extent, and the soil can be scraped flat. During the movement of the pull rope 12, a surface is formed on the backfill soil, which comprehensively determines the height of the backfill soil, improves the backfill accuracy, and is convenient and reliable to operate.

[0034] A specific application of this embodiment is: when the operator uses this device, the operator measures the size of the groove, splices the adjustment rod 1, first inserts the guide slider 10 on the side of the anchor rod 3 into the guide slot 9 on the side of the adjustment rod 1, and then uses the bolt nut 11 to lock and fix. Then insert the vertical rod 4 into the rectangular frame opened by the adjustment rod 1, use two first nuts 6 to lock, then screw the positioning plate 5 into the vertical rod 4, and insert the vertical rod 4 into the folding rod 2. Then the operator inserts the adjustment rod 1 and the folding rod 2 into the soil on the side of the foundation pit 11, and operates the anchor rod 3 to insert into the soil at the bottom of the foundation pit 11. According to the depth of the anchor rod 3 inserted into the soil plus the depth of the soil layer to be backfilled, find the marking line position corresponding to the first scale line of the anchor rod 3, adjust the bottom of the positioning plate 5 to be flush with this marking line, and use two second nuts 7 to pre-tighten and fix, and determine the height of the soil to be filled. The adjusting rod 1 can be adjusted according to different pipeline grooves, and the folding rod 2 can be stored or unfolded according to the width of the foundation pit 11. At the same time, the device is inserted at a certain distance, and the pull rope 12 is tied on the positioning plate 5 of the adjacent devices. After the soil is landfilled, the second nut 7 below is loosened and the vertical rod 4 is in a state where the height position of the movable positioning plate 5 remains unchanged. By moving the vertical rod 4, the pull rope 12 can be driven to move. When the pull rope 12 moves, the flatness of the backfill soil can be seen. At the same time, during the movement of the pull rope 12, the protruding soil can be pushed to a certain extent to level the soil.
