Description

Technical Field

[0001] The present invention belongs to the technical field of foundation settlement monitoring, and particularly relates to a method for arranging settlement pipes to solve the problem of settlement of settlement pipes. Background Art

[0002] Soft soil refers to soil mainly composed of fine-grained soil in coastal marine facies, delta facies, inland plains or river facies, lake facies, swamp facies, etc. in mountainous areas. It has the characteristics of large void ratio, high natural water content, high compressibility and low strength, and most of them also have a highly sensitive structure. During the construction of port terminals, etc., it is often necessary to first reinforce the coastal soft soil to make it have a certain bearing capacity for the subsequent construction of the project. And during the soft foundation reinforcement process, it is often necessary to monitor the reinforcement settlement effect of the stratum, and layer settlement is one of the more commonly used and effective observation indexes.

[0003] A settlement pipe is a device used to monitor soil settlement. A magnetic ring is sleeved on the settlement pipe. During the monitoring process, the magnetic ring settles together with the soil, and then the settlement amount of the soil is represented by detecting the displacement amount of the magnetic ring. However, during the soft soil foundation settlement monitoring process, there will be a problem that the settlement pipe generates a certain settlement displacement under the action of the negative skin friction around the pipe, thus affecting the accuracy of the measured data of the magnetic ring.

[0045] In order to enable those in the technical field to better understand the solution of the present invention, the technical solution of the present invention will be further described below in conjunction with specific embodiments.

[0046] This embodiment provides a method for laying a settlement pipe to solve the problem of settlement of the settlement pipe. This method adopts: a drilling module 1, a layered settlement pipe module 2, a stone filling module 3, an unhooking device module 4, and a threaded anchoring module 5.

[0047] As Figure 1 shown, the drilling module 1 includes a drill tower 1-3, a drill pipe 1-2, a drill bit 1-1, etc., and is used to form a borehole on the ground.

[0048] As Figure 2 shown, the layered settlement pipe module 2 includes a settlement pipe 2-2, a pipe coupling 2-1, a magnetic ring 2-3, a pipe bottom plug 2-4, etc. The settlement pipe is formed by connecting multiple settlement pipe sections together through the pipe coupling 2-1. The magnetic ring 2-3 is sleeved on the settlement pipe 2-2, and the magnetic ring 2-3 is used to detect the settlement displacement of the formation. The pipe bottom plug 2-4 is installed at the bottom end of the settlement pipe 2-2 to block the bottom end of the settlement pipe and prevent sundries such as soil and stones from entering the pipe.

[0049] As Figure 3 shown, the stone filling module 3 includes a guide pipe 3-1 and a funnel 3-4 installed at the top of the guide pipe 3-1. The guide pipe 3-1 can be spliced by multiple sections of guide pipes to the required length. The guide pipe 3-1 is used to insert into the borehole 3-2 (the borehole 3-2 is constructed by the drilling module 1). Stones 3-3 are filled into the guide pipe 3-1 through the funnel 3-4, and the stones 3-3 are filled into the bottom of the borehole 3-2 through the guide pipe 3-1. Under the action of the guide pipe 3-1, it prevents the stones 3-3 from scattering on the hole wall and affecting the laying of the layered settlement pipe 2-2 and the movement of the magnetic ring 2-3.

[0050] As Figure 4As shown, the decoupler module 4 can be connected (threaded connection) to the drill pipe 1-2 of the drilling module 1 at its top, and can be detachably connected to the threaded anchoring module 5 at its bottom; the decoupler module 4 is used to place the threaded anchoring module 5 at the bottom of the borehole 3-2. Specifically, the decoupler module 4 includes a steel sleeve 4-1, which has a threaded structure inside for connecting to the drill pipe 1-2, and the lower part of the steel sleeve 4-1 contains a zigzag decoupling groove 4-2 for hanging and separating the threaded anchoring module 5.

[0051] As Figure 5 shown, the threaded anchoring module 5 is used to be stably fixed in the gravel 3-3 at the bottom of the borehole 3-2. To provide a support base with high-strength bearing capacity for the system, the threaded anchoring module 5 includes a bolt bottom 5-3, an anchor body 5-4, a connecting lug 5-2 and a limiting pit 5-1. Among them, the anchor body 5-4 is cylindrical, the bolt bottom 5-3 is fixedly connected to the bottom end of the anchor body 5-4, the bolt bottom 5-3 is conical and the outer wall is provided with a rotating thread. When rotating the threaded anchoring module 5, the bolt bottom 5-3 and the anchor body 5-4 can be drilled and buried into the gravel 3-3 at the bottom of the borehole 3-2 through the rotating thread on the bolt bottom 5-3; the connecting lug 5-2 is fixedly connected to the anchor body 5-4 for connecting to the decoupler module 4 to realize the placement and separation of the decoupler module 4 and the anchoring bolt 5; a limiting pit 5-1 is arranged at the top of the anchor body 5-4 for realizing a clamping fit with the bottom plug 2-4 of the layered settlement pipe module 2. Since the threaded anchoring module 5 can be stably fixed in the gravel 3-3 at the bottom of the borehole 3-2, and the threaded anchoring module 5 and the bottom plug 2-4 of the layered settlement pipe module 2 are in clamping fit, the stability of the layered settlement pipe module 2 can be ensured, and the problem of settlement of the settlement pipe can be avoided or reduced.

[0070] Step 4.1: Determine the assembly plan of the layered settlement pipe module 2 according to the drilling depth and the layout position of the magnetic rings 2-3;

[0071] Step 4.2: Assemble each pipe section of the settlement pipe 2-2, the magnetic rings 2-3, the connecting hoop 2-1 and the pipe bottom plug 2-4;

[0072] Step 4.3: Lower the assembled layered settlement pipe module 2 into the drill hole;

[0073] Step 4.4: Adjust the position of the settlement pipe 2-2 so that the pipe bottom plug 2-4 at the bottom of the settlement pipe is in clamping fit with the limit pit 5-1 at the top of the threaded anchoring module 5; since the threaded anchoring module 5 is stably fixed in the gravel 3-3 at the bottom of the drill hole 3-2, the layered settlement pipe module 2 can be ensured to be stable, avoiding or reducing the problem of settlement of the settlement pipe.

[0074] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device during use or operation. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Thus, the exemplary term "lower" can encompass both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein can be interpreted accordingly.

[0075] Moreover, relational terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.
