Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, in particular to an opening and closing mechanism and a wax-melting type horizontal drainage well. Background Art

[0002] Semi-diagenetic rocks usually refer to geological materials with hardness between rock and soil, such as soft rock, mudstone, shale, etc. These geological materials have a loose structure, large porosity and high water content. These groundwaters are sealed by the surrounding rock before tunnel excavation, forming a high pore water pressure. Once the surrounding rock is broken due to tunnel excavation, the high-pressure groundwater will be released quickly to form water gushing.

[0003] Therefore, during the excavation of semi-rock tunnels, if mud and water bursts occur, horizontal drainage is required. However, if the traditional drilling and pipe laying method is used, sudden water bursts may occur. The same problem occurs if the drainage pipe is directly driven in. Therefore, an opening and closing mechanism and a wax-melting horizontal drainage well are proposed, which can be used to block the water flow channel with paraffin in the case of water burst emergencies, maintain the groundwater level, avoid unnecessary groundwater loss, and ensure the stability of the surrounding soil. Summary of the invention

[0004] In view of the above problems existing in the prior art, the present invention is proposed.

[0005] Therefore, the present invention aims to solve the problem of sudden mud and water gushing during the excavation of a semi-rock tunnel.

[0006] To solve the above technical problems, the present invention provides the following technical solutions: a wax melting type horizontal drainage well, comprising a main body structure, including a guide head, a catheter component 1 located on the side of the guide head, and a catheter component 2 located on the side of the catheter component 1.

[0009] As a preferred solution of the wax melting type horizontal drainage well described in the present invention, the heating tube and the paraffin are of the same length.

[0010] As a preferred solution of the wax melting type horizontal drainage well described in the present invention, the second conduit assembly includes a pipeline, the pipeline is fixedly connected to the side of the double gravel filling pipe away from the guide head, the interior of the pipeline is a hollow structure, the end of the pipeline close to the double gravel filling pipe is fixedly connected to a booster pump, the end of the booster pump close to the double gravel filling pipe is fixedly connected to an inlet, the end of the booster pump away from the double gravel filling pipe is fixedly connected to an outlet, and the side of the outlet and located inside the pipeline is fixedly connected to a pressure tank.

[0011] As a preferred solution of the wax melting type horizontal drainage well described in the present invention, the diameters of the double gravel filling pipe and the pipeline are the same, and the pipeline is a steel casting.

[0012] The beneficial effects of the present invention are as follows: paraffin is heated to change from a solid state to a liquid state, and the liquid paraffin flows through a booster pump and the inside of a pressure tank to pressurize the paraffin. After the pressure tank is opened, the liquid paraffin will flow out faster, and the paraffin can be tightly filled into every corner of the water flow channel during the melting and solidification process. The liquid paraffin can adapt to cracks or pores of different shapes and sizes, and has a good blocking effect on irregular water flow channels, effectively isolating the water flow and achieving the purpose of interception. At the same time, the paraffin has a certain temperature resistance and can remain stable within a certain temperature range. It will not lose its blocking effect due to changes in underground temperature. If other construction operations are required in the area, the paraffin can be cleaned up without affecting subsequent work.

[0013] In view of the above problems and / or the problems existing in the prior art, an opening and closing mechanism is proposed.

[0014] Therefore, the present invention aims to solve the problem that the amount of paraffin wax can be freely controlled during the wax melting process in the prior art.

[0015] In order to solve the above technical problems, the present invention also provides the following technical solutions: including a wax melting type horizontal drainage well; and an opening and closing mechanism, including a closing component and a connecting component located inside the closing component.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Furthermore, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1-5 The present embodiment provides an opening and closing mechanism and a wax melting type horizontal drainage well, including a main mechanism 100, including a guide head 100a, a catheter component 1 101 located on the side of the guide head 100a, and a catheter component 2 102 located on the side of the catheter component 101.

[0033] Specifically, the guide head 100a is a conical structure, which is conducive to the movement of the entire structure in a semi-diagenetic tunnel. The guide head 100a is fixedly connected to the inside with a sensor 100b, which is a water pressure sensor for detecting the water pressure around the guide head 100a.

[0034] Furthermore, the catheter assembly 101 includes a double gravel-filled tube 101a, which is fixedly connected to the side of the guide head 100a. The double gravel-filled tube 101a is a cylindrical hollow structure. The double gravel-filled tube 101a can effectively filter out the mud, suspended matter and other particulate matter brought into the well with the water flow, increase the water penetration area, and enable the water flow to enter the soil around the well wall more evenly, thereby improving the water penetration efficiency and maintaining the stability of the overall structure. The interior of the double gravel-filled tube 101a is fixedly connected to a heating tube 101b, and the interior of the heating tube 101b is fixedly connected to paraffin 101c. The paraffin 101c is in the shape of a cylinder, and the heating tube 101b on the outside of the paraffin 101c is used to heat and melt the paraffin 101c.

[0035] Preferably, the heating tube 101b and the paraffin 101c have the same length, all the paraffin 101c can be melted by the heating tube 101b, and a mold for shaping the paraffin 101c is fixedly connected to the outer wall of the paraffin 101c. The melted wax is cooled inside the mold and is in a closed state, so as to prevent the paraffin 101c from overflowing onto the heating tube 101b and the double gravel filling tube 101a.

[0036] During the excavation of a semi-rock tunnel, after the device is pushed into the semi-rock formation by the thrust of a drilling rig or an excavator, when the sensor 100b detects that the guide head 100a has entered the interior, the sensor 100b detects the water pressure around the guide head 100a. When the water pressure exceeds the set rated value, the sensor 100b transmits data to the controller, and then the controller operates the heating pipe 101b to start. The heating pipe 101b heats the paraffin 101c to melt. After the melted paraffin 101c flows into the water gushing area, it can flow into the cracks or gaps. When the temperature drops, the paraffin 101c changes from liquid to solid, thereby blocking the water flow channel and reducing the infiltration of groundwater. At the same time, when water is gushing, the double gravel-filled pipe 101a can also control the flow of groundwater by adjusting the permeability of the gravel layer, thereby increasing the structural stability of the well wall and preventing erosion and further damage caused by water flow.

[0037] Example 2

[0038] Reference Figure 1-5 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0039] The second catheter assembly 102 includes a pipe 102a.

[0040] Specifically, the pipeline 102a is fixedly connected to the side of the double gravel-filled pipe 101a away from the guide head 100a, the interior of the pipeline 102a is a hollow sealing structure, the end of the pipeline 102a close to the double gravel-filled pipe 101a is fixedly connected to the booster pump 102b, the end of the booster pump 102b close to the double gravel-filled pipe 101a is fixedly connected to the inlet 102c, the inlet 102c is connected to the interior of the catheter assembly 101, the end of the booster pump 102b away from the double gravel-filled pipe 101a is fixedly connected to the outlet 102d, the side of the outlet 102d and located inside the pipeline 102a is fixedly connected to a pressure tank 102e, the pressure tank 102e is connected to the outlet 102d, and the outer wall of the pressure tank 102e is in close contact with the inner wall of the pipeline 102a.

[0041] Further, the double gravel-filled pipe 101a and the pipeline 102a have the same diameter, the guide head 100a has the same maximum diameter as the double gravel-filled pipe 101a and the pipeline 102a, and the pipeline 102a is a steel casting.

[0042] When the heating tube 101b starts heating, the paraffin 101c melts into a liquid state, flows into the interior of the booster pump 102b along the inlet 102c, and then flows out from the outlet 102d and enters the interior of the pressure tank 102e for storage, that is, the paraffin 101c enters the interior of the catheter component 101 from the interior of the catheter component 102 for storage and pressurization, which facilitates the outflow of the paraffin 101c.

[0043] Example 3

[0044] Reference Figure 1-5 , which is the third embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0045] The opening and closing mechanism 200 includes a closing component 201 and a connecting component 202 located inside the closing component 201 .

[0046] Specifically, the closing component 201 includes a valve seat 201a, which is a hollow cylinder. The valve seat 201a is fixedly connected to one end of the pipeline 102a away from the double gravel filling pipe 101a. The top of the valve seat 201a is rotatably connected to a sealing column 201b, the bottom surface of the sealing column 201b is fixedly connected to a valve body 201c, and the top of the sealing column 201b is fixedly connected to a wrench 201d.

[0047] Furthermore, the connecting component 202 includes a hole 202a, which is opened through the center of the surface of the valve body 201c, a through hole 202b is opened at the end of the valve seat 201a close to the pipe 102a, and a through hole 202c is opened at the end of the valve seat 201a away from the pipe 102a. The diameter of the hole 202a is larger than the through hole 1 202b and the through hole 2 202c, and the end of the side of the through hole 2 202c away from the guide head 100a is fixedly connected with a wax outlet tube 202d, and a plurality of water outlet holes 202e are evenly opened on the bottom surface of the valve body 201c.

[0048] Preferably, the valve body 201c is a spherical body, and the valve body 201c rotates inside the valve seat 201a, and the centers of the hole 202a, the through hole 1 202b, the through hole 202c and the wax outlet tube 202d are on the same horizontal plane.

[0049] In the initial state, the staff will turn the wrench 201d to drive the valve body 201c to block the through hole 1 202b and the through hole 2 202c. After a certain amount of liquid paraffin 101c is stored in the pressure tank 102e, the controller will operate the wrench 201d to connect the hole 202a, the through hole 1 202b, the through hole 202c and the wax outlet pipe 202d. At this time, the liquid paraffin 101c is accelerated from the pressure tank 102e, flows into the cracks or gaps in the water gushing area through the wax outlet pipe 202d, thereby blocking the water flow channel and reducing water loss.

[0050] When the liquid paraffin 101c in the pressure tank 102e has completely flowed out, the controller will operate the wrench 201d to rotate again, driving the sealing column 201b and the valve body 201c to rotate, and the through hole 1 202b and the through hole 202c are blocked. At this time, the pressure signal transmitted by the sensor 100b is judged. If the pressure value is still exceeded, the heating tube 101b continues to heat, and the melted liquid paraffin 101c flows into the pressure tank 102e through the inlet 102c, the booster pump 102b and the outlet 102d. When the liquid paraffin 101c in the pressure tank 102e is After 01c reaches the specified value, the controller operates the valve body 201c to rotate again, so that the hole 202a, the through hole 1 202b, the through hole 202c and the wax outlet pipe 202d are connected, and the liquid paraffin 101c flows out faster through this line, and the cracks or gaps in the water gushing area are blocked again until the water gushing is controlled. At this time, the sensor 100b transmits a normal data signal to the sensor, and the sensor closes the heating tube 101b, and then closes the through hole 1 202b and the through hole 2 202c through the valve body 201c. At this time, the water gushing is controlled.

[0051] When water gushes inside a semi-diagenetic tunnel, the water flow generates pressure, and after the sensor 100b detects a signal, the controller operates the valve body 201c to move, thereby causing the liquid paraffin 101c to spray out, and the paraffin 101c blocks the water outlet. During the spraying of the paraffin 101c, since the density of water is greater than the density of the paraffin 101c, the water flows into the interior of the valve seat 201a through the wax outlet pipe 202d and the second through hole due to the pressure. A plurality of uniform water outlet holes 202e are provided at the bottom of the valve seat 201a. Therefore, the gushing water is squeezed and flows into the interior of the valve seat 201a, and then discharged through the water outlet hole 202e. A pipeline is sealed and connected to the outside of the water outlet hole 202e. A drain pipe is added to the pipeline so that the water can drain by itself and the water pressure is monitored at the same time.
