Description

Technical Field

[0001] The utility model belongs to the technical field of underground soil layer settlement monitoring, and relates to a layer settlement pipe, in particular to a layer settlement pipe suitable for deep holes. Background Technique

[0002] With the acceleration of the urbanization process, the problems of ground settlement and underground layer settlement are becoming increasingly prominent, posing a serious threat to the building safety, underground pipelines, and traffic facilities in the city. Layer settlement observation is a widely used and technically mature monitoring method for underground soil body settlement monitoring at present. Its principle is to embed the settlement pipe into the underground soil body, install high-precision instruments inside the pipeline, and install settlement magnetic rings outside the settlement pipe. The settlement of the soil layer is determined by the displacement change of the magnetic ring outside the settlement pipe driven by the formation settlement. However, for the installation of layer settlement pipes in deep holes in thick Quaternary plain areas, there are many problems to be solved:

[0003] 1. When the drilling depth is relatively large, the drilled hole will inevitably have a certain slope, and the settlement pipe cannot be well centered during the installation process, which may lead to difficulties in installing the settlement pipe or the installation not being in place. It is difficult to adjust and cannot ensure the accuracy of the later monitoring data.

[0004] 2. During the process of drilling deep holes, in order to avoid cave-ins in the holes, thick slurry for protecting the wall needs to be filled in the deep holes. Due to the large consistency of the slurry for protecting the wall, the buoyancy force on the layer settlement pipe during the installation process is relatively large, so it is more difficult to lower the deep hole settlement pipe in the deep hole.

[0005] 3. Traditional settlement pipes are mostly welded. During the installation process of deep hole settlement pipes, due to the excessive hole depth and certain slope of the deep hole, there is a greater risk of fracture at the joints of the settlement pipes. Content of the Utility Model

[0006] The purpose of the utility model is to provide a layer settlement pipe suitable for deep holes, so as to solve the technical problems existing in the prior art that the settlement pipe applied to deep holes is prone to being not installed in place due to the influence of the slope of the deep hole during the process of being inserted into the deep hole, being difficult to lower due to the buoyancy force of the slurry for protecting the wall, and having a large risk of fracture at the joints of the settlement pipes.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0008] A layered settlement pipe applicable to deep holes, which comprises a weighted settlement pipeline, a monitoring settlement pipeline and a guiding mechanism. The weighted settlement pipeline and the monitoring settlement pipeline are alternately connected in a threaded connection manner through pipe clamps. A weight is arranged on the weighted settlement pipeline. The monitoring settlement pipeline is a non-magnetic pipeline. A settlement magnetic ring is sleeved outside the monitoring settlement pipeline. The guiding mechanism is sleeved outside the weighted settlement pipeline.

[0009] The pipe clamp is a non-magnetic pipe clamp, and the outer wall diameter of the pipe clamp is larger than the outer wall diameters of the weighted settlement pipeline and the monitoring settlement pipeline.

[0010] The weighted settlement pipeline is an iron pipe.

[0011] The monitoring settlement pipeline is a non-magnetic stainless steel pipe.

[0012] The guiding mechanism is a guide.

[0013] The guiding mechanisms are evenly arranged on the layered settlement pipe applicable to deep holes. The ratio between the number of used sections of the weighted settlement pipeline and the number of used guiding mechanisms is 2:1.

[0014] The beneficial effects of the present utility model are as follows: By providing a layered settlement pipe applicable to deep holes, and arranging the settlement pipelines in an alternating connection form of weighted settlement pipelines and monitoring settlement pipelines, the overall weight of the pipelines can be effectively increased, thereby effectively overcoming the buoyancy of the retaining wall mud on the settlement pipelines and reducing the difficulty of lowering the settlement pipelines during the process of lowering them in deep holes;

[0015] Threadedly connecting the weighted settlement pipeline and the monitoring settlement pipeline with a pipe clamp can effectively improve the stability of the connection between the weighted settlement pipeline and the monitoring settlement pipeline, improve the integrity of the settlement pipelines, effectively avoid their breakage from the connection during the process of lowering the settlement pipelines into deep holes, and improve the installation efficiency and quality of the settlement pipelines. Selecting a non-magnetic pipe clamp can ensure that when the settlement magnetic ring moves along the monitoring settlement pipeline, it will not cause magnetic interference to the settlement magnetic ring, thereby improving the accuracy of the magnetic ring data monitoring of the settlement magnetic ring by the high-precision instruments arranged inside the pipeline;

[0016] In addition, setting the guide can provide guidance for the settlement pipeline when lowering the settlement pipeline into the deep hole, facilitate adjustment, avoid the situation that the lowering and installation are not in place due to the certain inclination of the deep drill hole. At the same time, setting the guide outside the weighted settlement pipeline can use the pipe clamp to limit its position, thereby avoiding affecting the displacement of the settlement magnetic ring on the monitoring settlement pipeline.

[0017] The utility model effectively improves the installation quality and efficiency of the settlement pipeline in deep holes by using a simple structure, and is suitable for popularization and application in the field of underground deep soil layer settlement monitoring.

[0024] As Figures 1 to 4 shown, the utility model provides a layered settlement pipe applicable to deep holes, which includes a weighted settlement pipeline 1, a monitoring settlement pipeline 2 and a guiding mechanism. A weight is arranged on the weighted settlement pipeline 1 to increase the overall weight of the layered settlement pipe applicable to deep holes. In this embodiment, it is preferably an iron pipe with its own weight; the settlement magnetic ring 5 is sleeved outside the monitoring settlement pipeline 2 to monitor the formation settlement. Among them, in order to avoid magnetic interference to the settlement magnetic ring 5, the monitoring settlement pipeline 2 in this embodiment is made of non-magnetic material, preferably non-magnetic stainless steel pipe; and in order to improve the integrity of the settlement pipe main body and avoid the fracture at the connection between the weighted settlement pipeline 1 and the monitoring settlement pipeline 2 during the process of lowering and installing the settlement pipe main body along the deep hole, the weighted settlement pipeline 1 and the monitoring settlement pipeline 2 in this embodiment are alternately connected in a threaded connection form through a pipe clamp 4. The guiding mechanism is sleeved outside the weighted settlement pipeline 1, preferably a guide 3, which is used to provide guiding and straightening for the whole formed by the weighted settlement pipeline 1 and the monitoring settlement pipeline 2 when the settlement pipe main body is lowered and installed along the deep hole, so as to avoid being stuck by the deep hole due to the inclination of the deep hole and reduce the difficulty of lowering the settlement pipe main body.

[0025] In addition, in order to further reduce the magnetic interference on the settlement magnetic ring 5, the pipe hoop 4 in this embodiment is selected as a non-magnetic pipe hoop 4. In order to limit the settlement magnetic ring 5 and prevent it from sliding onto the counterweight settlement pipeline 1, the outer wall diameter of the pipe hoop 4 in this embodiment is larger than the outer wall diameters of the counterweight settlement pipeline 1 and the monitoring settlement pipeline 2.

In this embodiment, the aligning mechanism is evenly arranged on the layered settlement pipe suitable for deep holes and is arranged at intervals on the counterweight settlement pipeline 1.
