Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology, specifically a combined support for preventing the sinking of underground pipelines. Background Technology

[0002] Underground pipelines refer to municipal utility pipelines and their ancillary facilities built below the ground level in cities, such as water supply, drainage, gas, heating, electricity, and communications. They are important infrastructure for ensuring the operation of cities.

[0003] As a core infrastructure ensuring urban operation, the quality of underground pipelines directly affects the stable functioning of the city. In existing underground pipeline construction, the conventional process is to excavate trenches, lay pipelines, and backfill and compact them. However, this model has significant defects. The pipelines lack effective fixing structures and are easily affected by external factors such as vehicle vibration, natural soil consolidation, and groundwater infiltration during daily use, resulting in lateral displacement or longitudinal settlement.

[0004] To address this issue, the industry has gradually adopted supports to limit the movement of pipelines within trenches. However, existing supports still have key technological shortcomings, such as:

[0005] 1. Insufficient anti-settlement performance: Existing supports can only achieve simple pipe positioning and have not been designed with special protective structures for soil settlement. When there are large differences in soil density in different areas or complex geological conditions, land settlement will directly cause the supports and pipes to bend and shift synchronously, leading to safety hazards such as pipe rupture and leakage.

[0006] 2. Low installation efficiency: The connection of the various components of the bracket requires a complicated calibration process, and the stability after installation depends on the quality of the landfill. The construction cycle is long and the labor cost is high.

[0007] Therefore, a combined support for preventing sinking of buried pipelines is now designed to address this defect. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a combined support for preventing the subsidence of buried pipelines, which solves the problem that existing supports cannot effectively prevent the subsidence of buried pipelines.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a combined support for preventing subsidence of buried pipelines, comprising a plurality of combined support mechanisms installed inside the body of a pre-buried trench, wherein the plurality of combined support mechanisms are equidistantly arranged on the inner side of the pre-buried trench body, and a pipeline body is installed between the inner sides of the plurality of combined support mechanisms.

[0010] Preferably, the combined support mechanism includes a U-shaped bottom frame, which is located in the inner cavity of the pre-buried ditch body. The top of the U-shaped bottom frame is fixedly connected to a lower arc frame by a bracket. Both sides of the bottom of the U-shaped bottom frame are fixedly connected to positioning pins by fixing blocks, and the bottom end of the positioning pin penetrates the pre-buried ditch body and extends into the interior of the pre-buried ditch body.

[0011] Preferably, guide grooves are provided on both sides of the inner cavity of the U-shaped bottom frame, and guide seats are slidably installed on the inner side of the guide grooves. Inner pads are fixedly connected to the opposite sides of the two guide seats. An upper arc frame that cooperates with the pipe body and the lower arc frame is fixedly connected between the two inner pads by a bracket, and both the upper arc frame and the lower arc frame are in contact with the pipe body.

[0012] Preferably, an inner circular groove plate is fixedly connected to the lower part of each of the two inner pads on opposite sides, and a threaded bolt is provided on the inner side of the inner circular groove plate. Threaded cylinders are fixedly connected to both sides of the bottom of the U-shaped bottom frame cavity by fixing blocks, and the threaded bolts are threadedly connected to the inner side of the threaded cylinders.

[0013] Preferably, the front and rear sides of the inner cavity of the U-shaped bottom frame are provided with inclined slots extending to the outside. The front and rear sides of the inner pad are fixedly installed with inclined insert frames that cooperate with the inclined slots through openings. The inner sides of the inclined insert frames and the inclined slots are provided with tapered insert plates, and the end of the tapered insert plate away from the U-shaped bottom frame passes through the pre-buried ditch body and extends to the inner side of the pre-buried ditch body.

[0014] This utility model provides a combined support for preventing the subsidence of buried pipelines. Compared with existing technologies, it has the following advantages:

[0015] (1) The anti-sinking combined support for buried pipelines has several sets of combined support mechanisms inside the pre-buried trench body. The combined support mechanism is assembled and installed by a U-shaped bottom frame and an inner pad, so that the lower arc frame and the upper arc frame fix the pipeline body. It is used in conjunction with tapered insert plates. Several tapered insert plates are inserted obliquely into the pre-buried trench body, so that the U-shaped bottom frame has a lateral positioning function. Even if the soil at the bottom settles, the oblique resistance of the tapered insert plates can limit the overall position of the combined support mechanism, ensuring that the pipeline body will not bend and improving the overall service life of the equipment.

[0016] (2) The anti-sinking combination bracket for underground pipelines has corresponding guide grooves, guide seats, inclined slots and inclined inserts on both sides of the U-shaped bottom frame and the inner pad. The setting of these structures makes it convenient for workers to quickly connect and install during construction. They only need to insert the guide seat into the guide groove and push it to the bottom to install the other components directly without the need for complicated calibration procedures, which improves the convenience of use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a combined support for preventing subsidence of buried pipelines, including a plurality of combined support mechanisms 2 installed inside the pre-buried trench body 1, the plurality of combined support mechanisms 2 being equidistantly arranged on the inner side of the pre-buried trench body 1, and a pipeline body 3 being installed between the inner sides of the plurality of combined support mechanisms 2.

[0025] Furthermore, the combined support mechanism 2 includes a U-shaped bottom frame 201. The U-shaped bottom frame 201 is integrally formed from high-strength alloy material, which has good bending resistance and load-bearing performance. Its outer diameter is adapted to the inner width of the pre-buried trench body 1, and the U-shaped bottom frame 201 is located in the inner cavity of the pre-buried trench body 1. The top of the U-shaped bottom frame 201 is fixedly connected to a lower arc frame 202 through a bracket. The curvature of the inner arc surface of the lower arc frame 202 is adapted to the outer wall of the pipe body 3. A rubber vibration damping pad is pasted on the inner arc surface. The surface of the rubber vibration damping pad is provided with anti-slip texture, which not only enhances the stability of the pipe fixation, but also buffers vibration. Both sides of the bottom of the U-shaped bottom frame 201 are fixedly connected to positioning pins 203 through fixing blocks, and the bottom end of the positioning pins 203 penetrates the pre-buried trench body 1 and extends into the interior of the pre-buried trench body 1.

[0026] Guide grooves 206 are provided on both sides of the inner cavity of the U-shaped bottom frame 201. The groove wall of the guide groove 206 is provided with a lubricating coating to reduce sliding friction. Guide seats 207 are slidably installed on the inner side of the guide groove 206. Inner pads 204 are fixedly connected to the opposite side of the two guide seats 207. An upper arc frame 205 that cooperates with the pipe body 3 and the lower arc frame 202 is fixedly connected between the two inner pads 204 through a bracket. Both the upper arc frame 205 and the lower arc frame 202 are in contact with the pipe body 3.

[0027] The lower part of the two inner pads 204 on opposite sides is fixedly connected to an inner circular groove plate 208. The inner side of the inner circular groove plate 208 is provided with a threaded bolt 209. The two sides of the bottom of the U-shaped bottom frame 201 are fixedly connected to a threaded cylinder 210 by a fixing block, and the threaded bolt 209 is threadedly connected to the inner side of the threaded cylinder 210.

[0028] Both sides of the U-shaped base frame 201 have oblique slots 211 extending to the outside. Both sides of the inner pad plate 204 have oblique insert frames 212 that cooperate with the oblique slots 211 fixedly installed through openings at the front and rear. The oblique insert frames 212 and oblique slots 211 are provided with conical insert plates 213 on the inner side. The conical insert plates 213 are wedge-shaped and made of high-strength alloy steel. After being inserted into the oblique insert frames 212 and oblique slots 211, the tip extends into the soil on both sides of the pre-buried ditch body 1. The oblique support force resists the lateral tension caused by soil settlement and prevents the combined support mechanism 2 from shifting or bending as a whole. The end of the conical insert plate 213 away from the U-shaped base frame 201 penetrates the pre-buried ditch body 1 and extends to the inner side of the pre-buried ditch body 1.

[0029] Before use, the pre-buried trench body 1 is excavated using excavation equipment. The width of the inner side of the pre-buried trench body 1 is matched with the width of the U-shaped bottom frame 201. Then, several U-shaped bottom frames 201 are installed at equal intervals at the bottom of the inner cavity of the pre-buried trench body 1. During installation, the U-shaped bottom frames 201 are pressed firmly so that the bottom of the U-shaped bottom frames 201 fits against the bottom of the inner cavity of the pre-buried trench body 1, and the two bottom positioning pins 203 are also inserted into the interior of the pre-buried trench body 1. At this time, the U-shaped bottom frames 201 are fixed, and the two sides of the U-shaped bottom frames 201 also fit against the side walls of the inner cavity of the pre-buried trench body 1. Then, the pipe body 3 is placed on top of the lower arc frame 202. Then, the inner pad 204 is connected and installed with the U-shaped bottom frame 201 in sequence, first by connecting the guide seat 207 with the guide groove 206. The inner pad 204 is quickly installed with the U-shaped bottom frame 201. When the upper arc frame 205 contacts the pipe body 3 and the lower arc frame 202, the threaded bolt 209 and the threaded cylinder 210 are tightened with a tool to fix the lower arc frame 202 and the upper arc frame 205 and limit the position of the pipe body 3. Then, several tapered inserts 213 are inserted into the inclined insert frame 212 and the inclined slot 211 in sequence, and the tips of the tapered inserts 213 are inserted into the inner walls on both sides of the pre-buried trench body 1 with an inclined surface. In daily use, the U-shaped bottom frame 201, which is fixed by the positioning pin 203, can effectively prevent displacement. When the soil below is soft and sinks, the inclined insertion of several tapered inserts 213 can support the U-shaped bottom frame 201 and the inner pad 204, and prevent the pipe body 3 from sinking and bending.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
