Description

Technical Field

[0001] The invention belongs to the technical field of advanced water detection, and in particular relates to an advanced water detection system and a water detection method. Background Art

[0002] Advance water exploration means that in some areas, due to complex geological conditions or potential water hazards, water exploration must be carried out before mining to ensure the safety of mining. For example, during tunnel excavation, when the face is close to a cave, aquifer, quicksand layer or an area with a lot of water accumulation, or may be connected or close to a lake, river, reservoir or aquifer, advance water exploration is required.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0028] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] On the one hand, an embodiment of the present application provides an advanced water exploration system, including a seat body 1, a drilling assembly 2 and a detection assembly 3. The drilling assembly 2 is arranged on the seat body 1, and is used to form a borehole. The detection assembly 3 includes a pushing component 5, a pushing tube 4, a detection component 6 and a driving component. The detection component 6 is accommodated in the pushing tube 4. The pushing tube 4 includes a first end 12 inserted into the borehole. The first end 12 is provided with two shielding parts 7 rotatably arranged. A first elastic member is arranged between the shielding part 7 and the pushing tube 4. The two shielding parts 7 close the first end 12. The driving component is used to drive the detection component 6 to move out of the pushing tube 4 from the first end 12. The pushing component 5 is arranged on the seat body 1, and is used to push the pushing tube 4 into the borehole.

[0030] The base body 1 is used for installing the drilling component 2 and the detection component 3.

[0031] The drilling assembly 2 is used for drilling. The drilling assembly 2 can be selected from the existing structure. In general, the drilling assembly 2 can include a driving device and a drill bit. The driving device can be a motor or a fuel engine. The drill bit is connected to the output end of the driving device so that the driving device can drive the drill bit to rotate.

[0032] The jacking pipe 4 is used to send the detection component 6 into the borehole on the inner wall of the tunnel, so that the detection component 6 can penetrate deep into the borehole.

[0033] The detection component 6 can be an acoustic wave detection device. The working principle of the acoustic wave detection device is well known to those skilled in the art. In summary, the detection component 6 can include an acoustic wave probe and a processor. The acoustic wave probe and the processor are electrically connected. The acoustic wave probe sends out an acoustic wave signal, which generates a reflected signal after propagation. After the processor analyzes the reflected signal, the geology in front of the borehole can be analyzed to achieve the purpose of water detection.

[0034] In an embodiment in which the detection component 6 includes an acoustic wave probe and a processor, the processor can be fixedly disposed on the seat body 1 , and the acoustic wave probe is located in the push tube 4 .

[0035] In the embodiment of the present application, the inner wall of the tunnel is firstly drilled by the drilling assembly 2, and the geological conditions ahead are understood by analyzing the drill cuttings of the drilling, so as to achieve preliminary water detection. Then, further detection is performed by the detection component 6, which can verify whether the information obtained by drilling is accurate and increase the water detection range.

[0036] The driving component enables the detection component 6 to enter and exit the jacking tube 4 from the first end 12. Specifically, when the jacking tube 4 enters the borehole, the detection component 6 can be in the jacking tube 4, so that the jacking tube 4 can protect the detection component 6, reducing the risk of the detection component 6 being damaged by external force. After the jacking tube 4 is moved into place, the detection component 6 can be moved out by the driving component, so that the detection component 6 can play a detection role.

[0037] The shielding portion 7 is used to block the first end 12, reducing the risk of drill cuttings entering the jacking tube 4. Specifically, when the detection component 6 is in the jacking tube 4, the first elastic member allows the two shielding portions 7 to be in a relative state, and the two shielding portions 7 shield the first end 12 under the action of the first elastic member, reducing the risk of drill cuttings entering the jacking tube 4. When the detection component 6 is moved out of the jacking tube 4, the detection component 6 can push the shielding portion 7 away, so that the shielding portion 7 does not hinder the movement of the detection component 6.

[0038] The pushing component 5 is used to drive the pushing tube 4 to move. For example, the pushing component 5 may include a moving device such as a cylinder or a hydraulic cylinder. The telescopic end of the cylinder or the hydraulic cylinder abuts against the pushing tube 4, so that the pushing tube 4 can be driven to move.

[0039] In the embodiment of the present application, the driving device and the moving device can be movably arranged on the base 1. When the drill bit is drilling, the driving device can move along the axial direction of the borehole so that the drill bit can gradually penetrate into the inner wall of the tunnel. After the drilling is completed, the drill bit is disconnected from the driving device, the driving device is removed, the moving device is moved to the position opposite the borehole, the push tube 4 is inserted into the borehole, and the push tube 4 is pushed into the borehole by the moving device. At the same time, the moving device itself can also move along the axial direction of the borehole. The specific connection structures of the driving device and the moving device with the base 1 can be selected from the existing structures. For example, the base 1 can be provided with a transverse slide rail and two longitudinal slide rails. The longitudinal slide rail extends along the axial direction of the borehole. The extension direction of the transverse slide rail is perpendicular to the longitudinal slide rail. The longitudinal slide rail is slidably connected to the transverse slide rail. The driving device and the moving device can be slidably connected to the two longitudinal slide rails respectively.

[0040] In the embodiment of the present application, the first elastic member may be a torsion spring or a spring. The specific configuration of the first elastic member is well known to those skilled in the art and will not be described in detail here.

[0041] In some embodiments, the two shielding portions 7 include a first side 28 arranged opposite to each other, and a semicircular through hole 22 is provided on the first side 28. The axis of the semicircular through hole 22 extends along the axis of the push tube 4. A recess 19 is provided on the peripheral wall surface of the detection component 6. The detection component 6 is configured such that when the detection component 6 extends a certain distance from the first end 12, the shielding portion 7 enters the recess 19, and the semicircular through hole 22 is arranged circumferentially around the recess 19.

[0042] When the two shielding parts 7 are arranged opposite to each other, the semicircular through holes 22 of the two shielding parts 7 are matched to form a circular through hole.

[0043] When the detection component 6 extends out of the push tube 4, the detection component 6 first pushes open the two shielding parts 7, so that the detection component 6 can move out from between the two shielding parts 7. After the detection component 6 moves out for a certain distance, the shielding part 7 can enter the recessed part 19 of the detection component 6, thereby reducing the risk of drill cuttings entering the push tube 4 from the gap between the shielding parts 7 and the detection component 6.

[0044] It should be noted that the length of the recessed portion 19 along the axial direction of the push tube 4 needs to be reasonably set so that when the semicircular through hole 22 and the recessed portion 19 cooperate, the movement of the detection component 6 will not be hindered.

[0045] In some embodiments, a accommodating cavity 21 is provided inside the shielding portion 7, and an opening is provided on the side wall of the semicircular through hole 22, the opening is connected to the accommodating cavity 21, the accommodating cavity 21 is semicircular, and the accommodating cavity 21 is circumferentially arranged around the semicircular through hole 22, and the accommodating cavity 21 is provided with an arc-shaped slide groove 23, and two extension sliding parts 25 are slidably connected at both ends of the arc-shaped slide groove 23, a second elastic member 24 is provided between the two extension sliding parts 25, and the two extension sliding parts 25 are connected by a connecting cable 27, the connecting cable 27 is laid on the arc-shaped slide groove 23, and the connecting cable 27 is connected to the flexible wall 20.

[0046] Since the extension sliding parts 25 are arranged at both ends of the arc-shaped slide groove 23, the two extension sliding parts 25 are connected by the connecting rope 27, and the connecting rope 27 is laid in the arc-shaped slide groove 23. Under the traction of the two extension sliding parts 25, the connecting rope 27 is in a straightened state, so that the flexible wall 20 can be stretched open by the two extension sliding parts 25. When the flexible wall 20 is stretched open, the flexible wall 20 is partially arranged in the accommodating cavity 21, and partially arranged in the semicircular through hole 22, so that the semicircular through hole 22 can be closed by the flexible wall 20, reducing the risk of reducing the shielding effect of the shielding part 7 due to the provision of the semicircular through hole 22.

[0047] When the shielding part 7 is accommodated in the recessed part 19, the detection part 6 applies pressure to the flexible wall 20, and the flexible wall 20 pulls the extension sliding part 25 to move into the accommodating cavity 21, so that the flexible wall 20 does not block the shielding part 7 from entering the recessed part 19. At the same time, since the two extension sliding parts 25 are connected by the second elastic member 24, under the pulling action of the extension sliding part 25, the flexible wall 20 will tightly abut against the outer peripheral wall of the detection part 6. On the one hand, the flexible wall 20 and the detection part 6 are in close contact, which reduces the risk of drill cuttings entering the push tube 4 from the gap between the detection part 6 and the semicircular through hole 22. On the other hand, the flexible wall 20 is tightly abutted against the outer peripheral wall of the detection part 6, so that the flexible wall 20 can fix the detection part 6, that is, the detection part 6 can be positioned by the flexible wall 20.

[0048] The second elastic member 24 may be a spring.

[0049] The flexible wall 20 may be a structure capable of generating elastic deformation. For example, the flexible wall 20 may be made of rubber.

[0050] In some embodiments, the driving component includes a support portion 8, the support portion 8 is accommodated in the push tube 4, the detection component 6 is connected to the support portion 8, the support portion 8 is provided with a matching portion 9, the inner wall surface of the push tube 4 is provided with a limiting slide groove 10, the limiting slide groove 10 includes a first segment 34 and a second segment 35, the first segment 34 extends along the axial direction of the push tube 4, the second segment 35 extends spirally, the second segment 35 is close to the first end 12, the matching portion 9 is inserted in the limiting slide groove 10, the two shielding portions 7 are respectively provided with insertion channels 15, the extension direction of the insertion channel 15 is perpendicular to the axis of the push tube 4, the support portion 8 is provided with an insertion portion 16 corresponding to the insertion channel 15, and the support portion 8 is configured so that when the matching portion 9 enters the second segment 35, the support portion 8 rotates around the axis of the push tube 4 so that the insertion portion 16 is inserted into the insertion channel 15.

[0051] The support portion 8 is received in the push tube 4 so that the support portion 8 can move along the axial direction of the push tube 4 .

[0052] The first section 34 extends along the axial direction of the push tube 4 . When the matching portion 9 is located in the first section 34 , the support portion 8 moves along the axial direction of the push tube 4 and does not rotate along the axial direction of the push tube 4 .

[0053] The second section 35 extends in a spiral manner. When the matching portion 9 is located in the second section 35 , the supporting portion 8 can move along the axial direction of the push tube 4 and can also rotate along the axial direction of the push tube 4 .

[0054] The first section 34 is used to initially move the detection component 6 out of the push tube 4. When the detection component 6 is moved a certain distance, the matching portion 9 enters the second section 35 from the first section 34. At this time, the support portion 8 rotates until the insertion portion 16 can be inserted into the insertion channel 15.

[0055] When the insertion portion 16 is inserted into the insertion channel 15, the shielding portion 7 can just enter the recessed portion 19. At this time, the two shielding portions 7 cannot rotate greatly relative to the pushing tube 4. The two semicircular through holes 22 can limit the detection component 6, so that the shielding portion 7 can fix the detection component 6, thereby reducing the risk of the detection component 6 escaping from the pushing tube 4.

[0056] Furthermore, when the insertion portion 16 is accommodated in the insertion channel 15, the support portion 8 cannot move further toward the first end 12, so that the shielding portion 7 can limit the support portion 8, so that the stroke of the support portion 8 can be fixed.

[0057] In the embodiment of the present application, two limiting sliding grooves 10 can be arranged in a 180° array on the inner wall of the push tube 4 .

[0058] In some embodiments, the mating portion 9 includes a cylinder 18 and a rod 17 , the cylinder 18 is connected to the supporting portion 8 , the rod 17 is inserted into the cylinder 18 , the rod 17 is inserted into the limiting slide groove 10 , and a third elastic member is arranged between the rod 17 and the cylinder 18 .

[0059] The rod body 17 is inserted into the cylinder body 18 so that the rod body 17 can move relative to the cylinder body 18 .

[0060] A third elastic member is provided between the rod body 17 and the cylinder body 18 . The third elastic member enables the rod body 17 to have a tendency to move away from the cylinder body 18 , that is, the rod body 17 can be kept in the limiting sliding groove 10 .

[0061] The third elastic member may be a spring.

[0062] In some embodiments, the driving component further includes a moving portion 11 , and the supporting portion 8 is rotatably connected to the moving portion 11 .

[0063] The moving part 11 is used to push the supporting part 8 to move.

[0064] The moving part 11 may be partially disposed outside the jacking tube 4 , so that when the jacking tube 4 is inserted into the borehole, the moving part 11 can be pushed externally, thereby enabling the moving part 11 to drive the supporting part 8 to move.

[0065] The push tube 4 may also be provided with a locking component to lock the moving part 11. The locking component may be selected from existing structures and will not be described in detail here.

[0066] In some embodiments, the middle part of the arc-shaped slide groove 23 corresponds to two extension sliding parts 25 and is slidably connected to two supporting sliding parts 26. The second elastic member 24 is set to two, and the second elastic member 24 connects the extension sliding part 25 and the supporting sliding part 26. The connecting rope 27 is correspondingly set to two, which respectively connect the extension sliding part 25 and the supporting sliding part 26. The accommodating cavity 21 is also provided with an elastic part 14, and the elastic part 14 is arranged between the two supporting sliding parts 26. The elastic part 14 includes a main body 31 and an elastic wall part 33 arranged on both sides of the main body 31. The two elastic wall parts 33 respectively abut against the two supporting sliding parts 26. The shielding part 7 is provided with a limiting part 13, and the limiting part 13 is arranged between the two elastic wall parts 33. The shielding part 7 is provided with a sliding hole connecting the accommodating cavity 21 and the insertion channel 15, and the main body 31 abuts against the insertion part 16 via the sliding hole.

[0067] The supporting sliding portion 26 is slidably connected to the arc-shaped sliding groove 23 , so that the distance between the supporting sliding portion 26 and the corresponding extending sliding portion 25 can be adjusted.

[0068] When the shielding portion 7 is partially accommodated in the recessed portion 19 , under the pulling action of the flexible wall 20 , the distance between the extending sliding portion 25 and the end of the arc-shaped sliding groove 23 is greater than zero.

[0069] When the supporting sliding portion 26 moves toward the direction approaching the extending sliding portion 25, the compression degree of the second elastic member 24 increases, and then the elastic restoring force generated by the second elastic member 24 increases. The second elastic member 24 can push the extending sliding portion 25 to move as far as possible toward the end of the arc-shaped slide groove 23. In an embodiment in which the flexible wall 20 is a structure capable of generating elastic deformation, such an arrangement can increase the circumferential length of the flexible wall 20 around the detection component 6, i.e., increase the shielding area of ​​the flexible wall 20, thereby reducing the risk of drill cuttings entering the jacking pipe 4.

[0070] The elastic portion 14 includes a main body 31 and elastic wall portions 33 disposed on both sides of the main body 31 . The main body 31 is inserted into the sliding hole so that the main body 31 can move relative to the sliding hole.

[0071] The limiting portion 13 is disposed between the two elastic wall portions 33. On the one hand, when the insertion portion 16 is inserted into the insertion channel 15, the insertion portion 16 pushes the main body 31 to move, and the two elastic wall portions 33 are pushed apart by the limiting portion 13 and deformed. The elastic wall portions 33 produce elastic deformation, so that the main body 31 can remain against the insertion portion 16, reducing the risk of the insertion portion 16 escaping from the insertion channel 15. On the other hand, when the insertion portion 16 pushes the main body 31, under the action of the limiting portion 13, the two elastic wall portions 33 separate, and the elastic wall portions 33 can push the supporting sliding portion 26 to move toward the extending sliding portion 25, that is, the length of the flexible wall 20 circumferentially arranged around the detection component 6 is increased.

[0072] In order to facilitate the insertion portion 16 to push the main body 31 to move, the surface of the insertion portion 16 facing the main body 31 may be an inclined surface.

[0073] In some embodiments, the port of the sliding hole located in the accommodating cavity 21 is set on the first wall 32 of the accommodating cavity 21, and the elastic wall portion 33 includes a first section 29 and a second section 30 connected in sequence, the first section 29 is connected to the side of the main body 31 facing the limiting portion 13, the first section 29 is bent, the inner curved sides of the two first sections 29 are arranged back to back, the spacing between the two first sections 29 close to the side of the main body 31 is smaller than the spacing away from the side of the main body 31, the second section 30 is connected to the side of the first section 29 away from the main body 31, the second section 30 is curved, and the inner curved side of the second section 30 is arranged back to the first wall 32, and the second section 30 is used to push the support sliding portion 26.

[0074] When the main body 31 moves toward the limiting portion 13, the limiting portion 13 first separates the two first sections 29, and the first section 29 undergoes elastic deformation. Since the first section 29 is bent, the second section 30 moves toward the first wall 32. When the second section 30 contacts the first wall 32, the inner curved side of the second section 30 is disposed facing away from the first wall 32, so that the second section 30 can extend in a direction away from the main body 31, thereby enabling the second section 30 to push the supporting sliding portion 26 to move.

[0075] Furthermore, since the inner curved side of the second section 30 is arranged to face away from the first wall surface 32, when the second section 30 is deformed, the second section 30 can generate thrust toward the first wall surface 32, thereby reducing the risk of the limit portion 13 being stuck between the two first sections 29 and unable to escape.

[0076] The spacing between the two first sections 29 on the side close to the main body 31 is smaller than the spacing on the side away from the main body 31. The advantage of this arrangement is that, on the one hand, when the limiting portion 13 separates the two first sections 29, the second section 30 can be moved toward the direction close to the first wall surface 32. On the other hand, when the insertion portion 16 withdraws from the insertion channel 15 and the force acting on the main body 31 from the insertion portion 16 disappears, the elastic restoring force of the first section 29 can enable the limiting portion 13 to withdraw from between the two first sections 29.

[0077] On the other hand, an embodiment of the present application provides an advanced water detection method, which is applied to the advanced water detection system in the above embodiment, including:

[0078] Drilling holes into the inner wall of the tunnel by means of the drilling assembly 2;

[0079] Take out the drill bit of the drilling assembly 2 and insert it into the borehole through the jacking tube 4;

[0080] The detection component 6 is moved out of the jacking tube 4 by the driving component, and the water detection operation is performed through the detection component 6. The number of jacking tubes 4 can be set according to the number of boreholes, that is, one jacking tube 4 is set in one borehole.

[0081] In some embodiments, the number of the boreholes is at least two, and the axes of the multiple boreholes intersect at one point.

[0082] The intersection of the axes of the multiple boreholes can be located in the tunnel, and the multiple boreholes extend radially. As the depth of the boreholes increases, the spacing between two adjacent boreholes gradually increases. On the one hand, the number of times the seat body 1 needs to be moved is reduced, and the water detection efficiency is improved. On the other hand, the detection range of a single detection component 6 is increased, thereby reducing the number of detection components 6 required to be set.

[0083] The above embodiments are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
