Description

Technical Field

[0001] This invention relates to the field of rescue channel technology, and more specifically, to a method for rapidly constructing a track-type rescue channel in an underground well. Background Technology

[0002] In related technologies, the construction of rescue passages using large-section support methods reduces the workload of clearing all the collapsed debris, accelerating rescue efficiency. It also allows rescuers to walk upright within the passage, providing them with relatively free movement. However, this method also has certain drawbacks. Due to the large-section support operation, the disturbance to the overlying collapsed debris during the clearing process is significant, increasing stress concentration during the construction of the rescue passage and increasing the risk of secondary collapse, potentially damaging the rescue passage. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, this invention proposes a method for rapidly constructing a track-type rescue channel in underground collapsed loose material, which can safely and efficiently construct a rescue channel and facilitate the rescue of trapped personnel.

[0005] The rapid construction method for a track-type rescue channel in wells according to an embodiment of the present invention includes the following steps:

[0006] S1: A plurality of fixed rods are arranged through the pile along the extension direction of the pile;

[0007] S2: Multiple support rods are connected to the front ends of multiple fixed rods to connect and fix the multiple fixed rods. The multiple support rods are connected in sequence to form a closed loop structure. The multiple fixed rods and the multiple support rods constitute the main support frame.

[0008] S3: A guide assembly is arranged on the inner side of the main support frame, and the extension direction of the guide assembly is in the same direction as the extension direction of the stacked body;

[0009] S4: Arrange multiple support shells sequentially along the extension direction of the guide assembly, and clear the accumulated material inside each of the multiple support shells to form a rescue channel.

[0010] The rapid construction method of the underground sliding track rescue channel in this invention adopts a construction method in which the main support frame penetrates through the stable overlying accumulation body and the support shell is advanced alternately and progressively. This can form a double-stable support method, which can reduce the risk of secondary collapse of the accumulation body, increase the stability and safety of the rescue channel, and protect the lives of rescue personnel during the rescue process.

[0011] In some embodiments, the fixing rod has an inner hole channel, which is disposed along the extending direction of the fixing rod and extends through the fixing rod. The arrangement of the fixing rod includes the following steps:

[0012] S11: Control the drill rod with the reaming blade to pass through the inner hole channel and make the reaming blade extend to the outside of the fixed rod, wherein the reaming blade has two states: closed and open. In the closed state, the radial dimension of the reaming blade is smaller than the radial dimension of the inner hole channel, and the reaming blade can pass through the inner hole channel. In the open state, the reaming blade is suitable for cutting the pile.

[0013] S12: The drill rod and the reaming blade in the unfolded state are driven to rotate by the drill rig and drill a hole in the pile body to form a hole. The fixing rod is controlled to enter the hole until the fixing rod penetrates the pile body.

[0014] S13: Remove the drill rod and the reaming tool from the borehole.

[0015] In some embodiments, in the unfolded state of the reaming blade, the radial dimension of the reaming blade is larger than the radial dimension of the fixing rod, and the arrangement of the fixing rod further includes the following steps:

[0016] Before drilling with the enlarging blade, wrap an airbag around the outer periphery of the fixing rod;

[0017] After the fixing rod penetrates the pile, air or liquid is injected into the airbag to fill the cavity between the fixing rod and the inner wall of the borehole, thereby improving the stability of the pile around the borehole.

[0018] In some embodiments, there are three fixed rods and three support rods. The three fixed rods are arranged in a triangle within the stack, and the three support rods are connected between two adjacent fixed rods to form a triangular main support frame.

[0019] In some embodiments, the guiding assembly includes a first guide and a second guide, the first guide being located above the second guide, and the first guide and the second guide being respectively connected to adjacent support rods.

[0020] In some embodiments, the support housing has an extended state and a retracted state. In the extended state, the support housing has a rescue cavity. The support housing is adapted to be connected to the guide assembly and is slidable along the extension direction of the guide assembly. The rescue cavity is adapted to allow the support housing in the retracted state to pass through.

[0021] In some embodiments, the support housing includes a first support plate, a second support plate, a first adjusting member, and a second adjusting member. The first support plate is disposed above the second support plate. The first support plate and the second support plate are extendable and retractable along the width direction of the stack. The first adjusting member and the second adjusting member are spaced apart along the width direction of the stack and are respectively connected to the first support plate and the second support plate. The first adjusting member and the second adjusting member are adapted to adjust the distance between the first support plate and the second support plate.

[0022] In some embodiments, both the first support plate and the second support plate include a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are spaced apart along the width direction of the stack, and an elastic connector is provided between the first connecting plate and the second connecting plate.

[0023] In some embodiments, the formation of the rescue passage specifically includes the following steps:

[0024] S41: Connect the support housing, which is in the extended state, to the guide assembly;

[0025] S42: Clean up the buildup near the guide assembly to form a receiving cavity for placing the support housing in the extended state, and control the support housing to be placed in the receiving cavity;

[0026] S43: First, clean the accumulated material within the rescue cavity area inside the support housing, and then continue to clean the accumulated material near the guide assembly to form a receiving cavity for placing the next support housing in the expanded state;

[0027] S44: The support shell in the controlled retracted state passes through the rescue cavity of the cleared pile, and the support shell in the controlled retracted state is opened and placed in the corresponding receiving cavity and connected to the guide assembly;

[0028] S45: Repeat steps S43 and S44 until a rescue passage is formed.

[0029] In some embodiments, an auxiliary slide rail is provided on the bottom surface of the rescue cavity within the support housing, and the support housing in the retracted state is adapted to pass through the rescue cavity within the support housing in the expanded state via the auxiliary slide rail.

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figures 1 to 5 As shown, the rapid construction method for a track-type rescue channel in wells according to an embodiment of the present invention includes the following steps:

[0042] S1: Multiple fixed rods 2 that penetrate the pile 1 are arranged along the extension direction of the pile 1; specifically, the extension direction of the pile 1 can be defined as the front-back direction, and the width direction of the pile 1 can be defined as the left-right direction, so that multiple fixed rods 2 can be controlled to penetrate the pile 1 along the front-back direction.

[0043] S2: Multiple support rods 3 are connected to the front ends of multiple fixed rods 2 to connect and fix the multiple fixed rods 2. The multiple support rods 3 are connected sequentially to form a closed loop structure. The multiple fixed rods 2 and the multiple support rods 3 constitute the main support frame. Specifically, the support rods 3 can be installed at the front end of the stacked body 1. Each support rod 3 can be connected to two adjacent fixed rods 2 in a hinged manner, and the multiple fixed rods 2 can be connected end to end in series. After the multiple support rods 3 are connected to the fixed rods 2 respectively, they can form a closed loop structure. Furthermore, the multiple support rods 3 and the multiple fixed rods 2 embedded in the stacked body 1 can form a main support frame that supports and fixes the surrounding stacked body 1 during the construction of the rescue channel 12, which can reduce the disturbance to the stacked body 1 outside the main support frame during the construction of the rescue channel 12.

[0044] S3: A guide assembly 4 is arranged inside the main support frame, and the extension direction of the guide assembly 4 is in the same direction as the extension direction of the stack 1.

[0045] S4: Multiple support shells 5 are arranged sequentially along the extension direction of the guide component 4 in a progressive manner, and the accumulated bodies 1 inside the multiple support shells 5 are cleared to form a rescue channel 12.

[0046] Specifically, the guide component 4 can penetrate the pile 1 in the front-back direction and be located inside the main support frame. In addition, multiple support shells 5 can also be arranged sequentially in the pile 1 in the front-back direction and located inside the support frame. The guide component 4 can guide the installation of the support shells 5. Multiple support shells 5 can be connected to the guide component 4 respectively. The support shells 5 can be connected in the front and back. During the sequential installation of the support shells 5, after clearing the pile 1 located inside the support shells 5, a rescue passage 12 for rescuers to walk upright can be formed.

[0047] In some embodiments, there are three fixed rods 2 and three support rods 3. The three fixed rods 2 are distributed in a triangle within the stack 1, and the three support rods 3 are connected between two adjacent fixed rods 2 to form a triangular main support frame.

[0048] Specifically, there can be three fixed rods 2 and three support rods 3. The three fixed rods 2 can be inserted into the lower left, lower right and upper middle sides of the stack 1, respectively. At this time, the three support rods 3 can be hinged between the lower left fixed rod 2 and the lower right fixed rod 2, between the lower right fixed rod 2 and the upper middle fixed rod 2, and between the upper middle fixed rod 2 and the lower left fixed rod 2, respectively. After the three support rods 3 are connected, they can form a stable triangular structure. The support rods 3 on the lower left and lower right sides can be at the same height, and the triangular structure can be an isosceles triangle. This allows the three fixed rods 2 to be far away from the rescue channel 12 and can prevent the stability of the main support frame from changing due to the construction of the rescue channel 12.

[0049] The rapid construction method of the underground sliding rescue channel in this embodiment of the invention adopts a construction method in which the main support frame penetrates through the stable overlying accumulation body and the support shell is advanced alternately and progressively. This can form a double-stable support method, which can reduce the risk of secondary collapse of the accumulation body 1, increase the stability and safety of the rescue channel 12, and protect the lives of rescue personnel during the rescue process.

[0050] In some embodiments, the fixing rod 2 has an inner hole channel 21, which is arranged along the extending direction of the fixing rod 2 and passes through the fixing rod 2. The arrangement of the fixing rod 2 includes the following steps:

[0051] S11: Control the drill rod 62 with the reaming blade 61 to pass through the inner hole channel 21 and make the reaming blade 61 extend to the outside of the fixed rod 2. The reaming blade 61 has two states: closed and open. In the closed state, the radial dimension of the reaming blade 61 is smaller than the radial dimension of the inner hole channel 21. At this time, the reaming blade 61 can pass through the inner hole channel 21. In the open state, the reaming blade 61 is suitable for cutting the pile 1.

[0052] Specifically, such as Figure 3 As shown, when the reaming blade 61 is in the closed state, the reaming blade 61 can be attached to the outside of the drill rod 62 or hidden inside the drill rod 62. At this time, it is convenient to control the drill rod 62 and the reaming blade 61 installed at the end of the drill rod 62 to pass through the inner hole channel 21. When controlling the reaming blade 61 to pass through the inner hole channel 21 and extend to the outside of the fixed rod 2, the reaming blade 61 can be controlled to unfold towards the outer periphery of the drill rod 62.

[0053] S12: The drill rod 62 and the reaming cutter 61 in the unfolded state are driven to rotate by the drill rig and drill a hole in the accumulator 1 to form a borehole 11. The fixing rod 2 is controlled to enter the borehole 11 until the fixing rod 2 penetrates the accumulator 1.

[0054] S13: Remove drill rod 62 and reaming tool 61 from borehole 11.

[0055] Specifically, the drill rod 62 can rotate under the drive of the drilling machine, which in turn drives the unfolded reaming blade 61 to rotate, thus drilling a hole at the position where the fixing rod 2 is to be installed. During the drilling process, the fixing rod 2 can be gradually inserted into the formed drill hole 11. Once the fixing rod 2 penetrates the pile 1, the drilling machine stops operating. Then, the reaming blade 61 can be controlled to fit against the outside of the drill rod 62 or be hidden inside the drill rod 62. The drill rod 62 and the reaming blade 61 can then be removed from the inner hole channel 21 of the fixing rod 2.

[0056] In some embodiments, when the reaming blade 61 is in its unfolded state, the radial dimension of the reaming blade 61 is larger than the radial dimension of the fixing rod 2, and the arrangement of the fixing rod 2 further includes the following steps:

[0057] Before drilling with the reamer 61, an airbag 63 is wrapped around the outer periphery of the fixing rod 2; after the fixing rod 2 penetrates the pile 1, air or liquid is injected into the airbag 63 so that the airbag 63 fills the cavity between the fixing rod 2 and the inner wall of the borehole 11, thereby improving the stability of the pile 1 around the borehole 11.

[0058] Specifically, such as Figure 3 and Figure 4 As shown, the airbag 63 can be connected to the outer periphery of the fixing rod 2 by adhesive bonding. The airbag 63 can have gas / liquid inlet and outlet ports and can have the characteristics of flexibility, friction resistance and high compressive strength. After the airbag 63 enters the borehole 11 in the accumulation body 1 along with the fixing rod 2, air or liquid can be injected into the airbag 63 to expand its volume and support and tightly adhere to the accumulation body 1 outside the borehole 11, which can increase the stability of the fixing rod 2 in the accumulation body 1. After the rescue work is completed, the gas or liquid in the airbag 63 can be released to increase the gap between the fixing rod 2 and the accumulation body 1, and the fixing rod 2 can be removed from the borehole 11 by the drilling rig and recycled for reuse, increasing the reusability rate and reducing the rescue cost.

[0059] Next, following the arrangement steps of the fixed rods 2 described above, the remaining fixed rods 2 can be inserted into the stacked body 1 in the predetermined positions. After connecting the support rods 3, the main support frame is completed.

[0060] In some embodiments, the guide assembly 4 includes a first guide member 41 and a second guide member 42, the first guide member 41 being located above the second guide member 42, and the first guide member 41 and the second guide member 42 being respectively connected to adjacent support rods 3. Specifically, as Figure 1 and Figure 2As shown, the guide assembly 4 may have two first guide members 41 and two second guide members 42. The two first guide members 41 may be distributed at intervals inside the stack 1 along the left and right direction, and the two second guide members 42 may be located below the two first guide members 41 in a corresponding manner.

[0061] During the arrangement of the support shell 5, the guide assembly 4, consisting of two first guide members 41 and two second guide members 42, can guide and limit the support shell 5. In addition, the first guide members 41 and the second guide members 42 can be inserted into the stacked body 1 with reference to the construction method of the fixed rod 2. After the two first guide members 41 and the two second guide members 42 are inserted into the stacked body 1 in sequence, the front ends of the first guide members 41 and the second guide members 42 can be hinged to the nearest support rod 3, which can improve the stability of the guide assembly 4.

[0062] In some embodiments, the support housing 5 has an open state and a retracted state. In the open state, the support housing 5 has a rescue cavity. The support housing 5 is adapted to be connected to the guide assembly 4 and can slide along the extension direction of the guide assembly 4. The rescue cavity is adapted to allow the support housing 5 in the retracted state to pass through. The support housing 5 having an open state and a retracted state can facilitate the sequential delivery of multiple support housings 5 ​​into the stack 1 in a specific direction, which can improve the construction speed of the rescue channel 12 and facilitate the rapid deployment of rescue work.

[0063] In some embodiments, the support housing 5 includes a first support plate 51, a second support plate 52, a first adjusting member 53, and a second adjusting member 54. The first support plate 51 is disposed above the second support plate 52. The first support plate 51 and the second support plate 52 can extend and retract along the width direction of the stack 1. The first adjusting member 53 and the second adjusting member 54 are distributed at intervals along the width direction of the stack 1 and are respectively connected to the first support plate 51 and the second support plate 52. The first adjusting member 53 and the second adjusting member 54 are adapted to adjust the distance between the first support plate 51 and the second support plate 52.

[0064] Specifically, such as Figure 5As shown, the first support plate 51, the second support plate 52, the first adjusting member 53, and the second adjusting member 54 can form a support shell 5 with a rectangular cross-section. The first adjusting member 53 can be connected between the left end of the first support plate 51 and the left end of the second support plate 52, and the second adjusting member 54 can be connected between the right end of the first support plate 51 and the right end of the second support plate 52. By controlling the contraction of the first support plate 51 to shorten the distance from its left end to its right end, and by controlling the contraction of the second support plate 52 to shorten the distance from its left end to its right end, the support shell 5 can be contracted in the left-right direction. By controlling the contraction of the first adjusting member 53 and the second adjusting member 54 to shorten the distance between the first support plate 51 and the second support plate 52, the support shell 5 can be contracted in the up-down direction.

[0065] The first adjusting member 53 and the second adjusting member 54 can be hydraulic control members with folding function. By controlling the degree of folding of the hydraulic control members, the distance between the first support plate 51 and the second support plate 52 can be adjusted. Alternatively, the first adjusting member 53 and the second adjusting member 54 can also be vertically arranged hydraulic cylinders. By extending and retracting the hydraulic cylinders, the distance between the first support plate 51 and the second support plate 52 can also be adjusted.

[0066] In some embodiments, both the first support plate 51 and the second support plate 52 include a first connecting plate 511 and a second connecting plate 512, the first connecting plate 511 and the second connecting plate 512 being spaced apart along the width direction of the stack 1, and an elastic connector 513 being provided between the first connecting plate 511 and the second connecting plate 512. Specifically, as Figure 5 As shown, the elastic connector 513 may include a spring. Through the elastic extension and contraction of the elastic connector 513, the first connecting plate 511 and the second connecting plate 512 can be controlled to move closer or further apart, thereby adjusting and controlling the distance from the left end to the right end of the first support plate 51 or the second support plate 52.

[0067] In some embodiments, an auxiliary slide rail 55 is provided on the bottom surface of the rescue cavity within the support housing 5, allowing the support housing 5 in its retracted state to pass through the rescue cavity within its expanded state via the auxiliary slide rail 55. Specifically, as... Figure 5 As shown, a slide rail converter can be provided at the rear end of the auxiliary slide rail 55. The support housing 5 to be installed can enter the installation position in the retracted state through the auxiliary slide rail 55 and the slide rail converter in the front open state of the support housing 5, which facilitates the movement and advancement of the support housing 5, saves more effort, and reduces the workload.

[0068] In some embodiments, such as Figures 1 to 5 As shown, the formation of rescue channel 12 specifically includes the following steps:

[0069] S41: Control the support shell 5 in the open state to connect with the guide assembly 4; specifically, the first support shell 5 installed first can be in the open state, and the left and right ends of the first support plate 51 in the support shell 5 can be controlled to be inserted and connected to the two upper first connectors respectively, the left and right ends of the second support plate 52 can be controlled to be inserted and connected to the two lower second connectors respectively, and the support shell 5 can be controlled to slide along the extension direction of the guide assembly 4.

[0070] S42: Clear the accumulated material 1 near the guide assembly 4 to form a receiving cavity for placing the support shell 5 in the open state, and control the support shell 5 to be placed in the receiving cavity; specifically, under the cover of the main support frame and the support shell 5, the accumulated material 1 near the guide assembly 4 can be broken, removed and cleared using high-strength ultra-light hydraulic demolition tools and hydraulic support devices to clear a receiving cavity that can accommodate the support shell 5, and promptly move and advance the support shell 5 into the receiving cavity for support, which can prevent the overlying accumulated material 1 from collapsing due to uneven force, affecting the support efficiency, and the guide assembly 4 can make the advancement and movement of the support shell 5 time-saving, labor-saving, convenient and quick.

[0071] S43: First, clean the accumulated material 1 within the rescue cavity area inside the support shell 5, and then continue to clean the accumulated material 1 near the guide component 4 to form a receiving cavity for placing the next support shell 5 in the expanded state; specifically, the cleaning sequence of the middle and then the outside can be adopted. First, the accumulated material 1 inside the installed support shell 5 is broken and cleaned to form the rescue channel 12, and then the accumulated material 1 around the guide component 4 is gradually cleaned to form a receiving cavity for placing the next support shell 5, which facilitates the construction of the rescue channel 12.

[0072] During this process, flexible anchor nets can be used to anchor the pile 1 outside the guide component 4, preventing the pile 1 outside the guide component 4 from collapsing and falling into the rescue channel 12. At the same time, due to the use of flexible anchor nets, the requirements for cleaning the pile 1 outside the first adjusting member 53 and the second adjusting member 54 are no longer stringent. There is no need to modify the cross-section of the rescue channel 12 to a regular cross-section. Under the condition that the overall structural stability of the rescue channel 12 is not affected and the normal progress of the rescue work is not affected, even if a large part of the pile 1 extends into the rescue channel 12, it does not need to be broken or removed. It only needs to be anchored using anchor nets to prevent secondary collapse of the pile 1 outside. This greatly saves the amount of work required for excavating the rescue channel 12 and improves the rescue efficiency.

[0073] S44: The support shell 5 in the controlled contracted state passes through the rescue cavity of the cleaned-up pile 1, and the support shell 5 in the controlled contracted state is opened and placed in the corresponding receiving cavity and connected to the guide assembly 4; specifically, the support shell 5 in the contracted state can pass through the installed support shell 5 and enter the receiving cavity immediately adjacent to the rear end with the cooperation of the auxiliary slide rail 55 and the slide rail converter, and is opened under the action of the elastic connector 513, the first adjusting member 53 and the second adjusting member 54, and can be inserted and connected to the guide assembly 4, which can prevent the overlying pile 1 from collapsing again.

[0074] S45: Repeat steps S43 and S44 until the rescue channel 12 is formed. By adopting a progressive support operation, the construction of the rescue channel 12 can be completed.
