Description

Technical Field

[0001] This utility model relates to the field of underground pipeline construction technology; specifically, this utility model relates to a construction tool for complex underground pipelines with protective properties. Background Technology

[0002] In the process of constructing municipal roads, we face many problems such as numerous surrounding buildings, roads, underground pipelines, and complex geological conditions. In some areas, there are also complex geological conditions such as highly sensitive soil, severely liquefiable soil stratification, and densely arranged pipelines that intersect with existing road pipelines at perpendicular angles. This places high demands on the protection of existing road pipelines and surrounding buildings and makes construction difficult.

[0003] In existing technologies, for the construction of complex underground pipelines and the protection of existing pipelines and surrounding buildings, the process involves dewatering, excavating foundation pits, and then using tensioned steel sheet piles for support. New pipelines are then installed by placing the pipes into the foundation pit using a crane. The construction of underground pipelines is carried out in sections. However, the connection between the new pipelines and existing road pipelines requires manual entry into the foundation pit for docking and installation. Large equipment cannot be effectively used to assist in the construction and installation process, which is quite inconvenient. Utility Model Content

[0004] In view of this, the present invention provides a construction tool for complex underground pipelines with protective properties, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0005] To achieve the aforementioned objective, this utility model provides a construction tool for complex underground pipelines with protective properties, comprising: two clamping structures, each clamping structure including a first arc-shaped plate and a second arc-shaped plate that can open and close to each other; a circular area capable of clamping the pipeline is formed between the first arc-shaped plate and the second arc-shaped plate;

[0006] Two U-shaped plates are provided, which are fixedly installed on the opposite sides of the first arc-shaped plate and the second arc-shaped plate respectively;

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

[0024] like Figures 1 to 4 As shown, a typical embodiment of this utility model provides a construction tool for complex underground pipelines with protective properties, comprising:

[0025] Two clamping structures 1, each clamping structure 1 includes a first arc-shaped plate 1-1 and a second arc-shaped plate 1-2 that can open and close to each other; a circular area capable of clamping the pipe is formed between the first arc-shaped plate 1-1 and the second arc-shaped plate 1-2.

[0026] Two U-shaped plates 2 are provided, which are respectively fixedly installed on the opposite sides of the first arc plate 1-1 and the second arc plate 1-2;

[0027] The support leg 3 is slidably mounted on the U-shaped plate 2, and the bottom end of the support leg 3 can be inserted into the ground;

[0028] The boom 4 is connected to the support leg 3 at the bottom. The boom 4 can be engaged with the clamping structure 1 in the height direction. A lifting ring 5 is fixedly installed at the top of the boom 4.

[0029] In this embodiment, a clamping structure 1 is provided at both ends of the pipe. The first arc plate 1-1 and the second arc plate 1-2 can clamp the pipe from both sides respectively. During the hoisting process, the lifting device is connected to the lifting rings 5 ​​on the lifting arms 4 on both sides of the clamping structure 1 at both ends of the pipe to lower the pipe into the pit. The lifting arms 4 and the clamping structure 1 are engaged to stably support the clamping structure 1, so that the lifting device can stably lower the pipe into the pit.

[0030] When the pipeline is lowered into the pit, the support leg 3 contacts the ground and the bottom of the support leg 3 can be inserted into the ground to serve as a temporary support, keeping the pipeline in place and preventing it from rolling or shifting, which would affect subsequent construction.

[0031] The clamping structure 1 also includes: a limiting plate 6, of which there are two, which are fixedly installed on the top of the first arc plate 1-1 and the second arc plate 1-2 respectively, and slide in a lateral manner with each other, and the boom 4 is clamped on the side of the limiting plate 6 away from the pipe.

[0032] In this embodiment, the support leg 3 is pulled out of the ground, and then the first arc plate 1-1 or the second arc plate 1-2 is slid by the limiting plate 6, so that the first arc plate 1-1 and the second arc plate 1-2 are unfolded away from the pipe, making it easy to dismantle and applicable to the hoisting of the next pipe.

[0033] Support leg 3 includes: telescopic rod 3-1, which is slidably mounted on U-shaped plate 2 in the lateral direction;

[0034] Diagonal brace 3-2 is fixedly installed at the bottom of telescopic pole 3-1;

[0035] The pivot 3-3 is rotatably mounted on the top of the diagonal bar 3-2, and the bottom of the boom 4 passes through the pivot 3-3 in the height direction;

[0036] Insert rod 3-4 is located at the bottom of the diagonal rod 3-2. The bottom of insert rod 3-4 is tapered so that it can be inserted into the ground.

[0037] In this embodiment, taking the first arc plate 1-1 as an example, when aligning with the existing pipeline, the boom 4 slides downward to disengage from the limiting plate 6. The boom 4 can rotate in the circumferential direction along the pivot 3-3, pulling the support leg 3 on one side of the first arc plate 1-1 out of the ground, allowing the first arc plate 1-1 to move to the left to the required position. Then, the support leg 3 on one side of the first arc plate 1-1 is inserted into the ground to stabilize the first arc plate 1-1. The boom 4 on the second arc plate 1-2 is then inserted below the second arc plate 1-2. The boom 4 is pressed down with the pivot 3-3 on one side of the second arc plate 1-2 as the fulcrum. The bottom of the boom 4 can push the second arc plate 1-2 to the left. At this time, the telescopic pipe slides laterally to the right on the U-shaped plate 2. The pipe can be pushed by the second arc plate 1-2 towards the first arc plate 1-1 until it contacts the first arc plate 1-1, thus adjusting the position of the pipe to the left. The same applies to the right side.

[0038] Insert the support legs 3 on both sides of the clamping structure 1 into the ground, and then insert the two booms 4 into the bottom of the first arc plate 1-1 and the second arc plate 1-2 respectively. Pressing down the two booms 4 at the same time can lift the first arc plate 1-1 and the second arc plate 1-2, thereby lifting the pipe between the first arc plate 1-1 and the second arc plate 1-2. At this time, the telescopic rods 3-1 on both sides of the pipe are stretched, achieving the effect of lifting the pipe. Construction workers can set up supports under the pipe.

[0039] By adjusting its lateral displacement and pipe lifting mechanism, it can precisely connect with existing pipelines. The operation is convenient and stable, which speeds up the construction progress and improves construction efficiency.

[0040] A threaded rod 3-5 is provided between the insert rod 3-4 and the inclined rod 3-2, and the threaded rod 3-5 is threadedly connected to the inclined rod 3-2.

[0041] In this embodiment, when the pipe is hoisted and lowered, the conical head at the bottom of the insertion rod 3-4 is inserted into the ground under the action of gravity. By rotating the threaded rod 3-5, the depth of insertion of the insertion rod 3-4 into the ground is controlled, making the tool more stable as a temporary support for the pipe.

[0042] The first arc plate 1-1 and the second arc plate 1-2 are both provided with grooves 1-3 on their opposite sides, and the width of the grooves 1-3 is the same as the width of the boom 4.

[0043] In this embodiment, when the boom 4 extends into the bottom of the first arc plate 1-1 or the second arc plate 1-2, it can contact the groove 1-3. The width of the boom 4 is the same as the width of the groove 1-3, and the boom 4 can extend into the groove 1-3, so that the first arc plate 1-1 and the second arc plate 1-2 can better bear the force when the boom 4 presses down.

[0044] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
