Description

Technical Field

[0001] This utility model relates to the field of grouting construction technology, specifically to a deep-hole curtain grouting borehole drainage device. Background Technology

[0002] With the continuous development of the country, the requirements for construction standardization are becoming increasingly important, and higher standards are also being set for on-site civilized construction. In order to create a standardized construction site, ensure the cleanliness of the construction surface, avoid the disorderly discharge of drilling wastewater, and create a new industry image, the project construction aims to achieve "balanced production, civilized construction, and scientific management" as the goals of civilized construction. The construction party must keep the construction site clean and hygienic as required. In the specific implementation process, in order to keep the work surface clean and reduce the disorderly discharge of drilling wastewater, higher investment is required as related expenses for civilized construction. Traditional deep hole curtain grouting drilling and drainage devices require additional manpower to stop the operation during the construction process to clean up the construction surface and remove disorderly discharged wastewater. This process not only increases labor costs but also leads to delays in construction progress and potential economic losses.

[0003] In response, a search revealed that CN222990873U discloses a deep-hole curtain grouting drilling drainage device. Addressing the issue that existing drainage devices require additional manpower for surface preparation and cleaning of disorderly discharged wastewater during construction, leading to increased labor costs and economic losses, the following solution is proposed: It includes a water collection tray and a drainage pipe. A mounting base is fixedly installed on one side of the water collection tray, and a drainage hole is opened on one side of the mounting base. A pre-reserved hole is opened at the center of the water collection tray, and a fixing component is installed within the inner ring of the pre-reserved hole. A connecting component is also included, mounted on the mounting base and used for the quick assembly and disassembly of the drainage pipe. Through the arrangement of the fixing component, connecting component, and water collection tray, efficient collection and orderly discharge of grout during deep-hole curtain grouting are achieved, improving construction efficiency and the safety of the working environment, thereby reducing labor costs and economic losses.

[0004] The aforementioned technology discloses a deep-hole curtain grouting borehole drainage device. Through a water collection pan and a fixing assembly consisting of two semi-circular frames through which the drill bit passes, the device effectively collects the grout discharged from the borehole and guides the collected grout outwards via a drainage pipe. This prevents the grout from flowing directly around the water collection pan, ensuring a clean and safe environment for deep-hole curtain grouting operations. However, the following shortcomings still exist in its use:

[0005] 1. The current method of fixing the inner component, consisting of two semi-circular frames, at four points using four anchor bolts lacks the effect of integrated fixing of the outer water collection tray. The water collection tray, simply fitted onto the outside of the two semi-circular frames, is prone to detachment from the ground due to vibration and other factors, resulting in poor stability. 2. The method of fixing using four anchor bolts individually lacks a medium for simultaneous fixing and unlocking at multiple points, leading to poor ease of fixing. Therefore, this application proposes a deep-hole curtain grouting drilling and drainage device to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a deep-hole curtain grouting drilling and drainage device to solve the problems mentioned in the background art.

The top of the outer protrusion is in movable contact with the bottom of the outer edge. The sealing sleeve is used to movably seal the outside of the central tube. The central tube is used to align with the borehole for the external drill bit to pass through. The water collection plate is used to contain and effectively collect the slurry discharged upward from the borehole through the central tube. The slurry is guided to the drainage pipe by the inclined surface of its bottom inner wall. The drainage pipe is used to connect to the external drainage pipe to discharge the slurry to the designated collection point, avoiding excessive drainage volume that would cause sewage to flow directly outside the water collection plate, thus ensuring the cleanliness and safety of the deep hole curtain grouting operation.

[0012] The spiral drill rod consists of six rods that are equally spaced and rotate in a ring at the bottom of an iron ring.

[0013] The rotary drive assembly is rotatably mounted on the outside of the iron ring and fixedly connected to the top of the six auger rods. The rotary drive assembly is used to drive the six auger rods to rotate and to drive the iron ring and the six auger rods to move downward when pressure is applied by personnel. The six auger rods rotate and move downward to drill into the ground for rooting and stabilizing, improving the stability of the water collection tray. When the water collection tray is fixed, the outer edge of the auger directly presses and fixes the central pipe, achieving the effect of positioning the water collection tray and the central pipe as a whole.

[0014] The guard vertical guide magnetic positioning component is installed on the outside of the annular groove and connected to the iron ring. The guard vertical guide magnetic positioning component is used to magnetically fix and support the iron ring when not in use, and to safely surround and protect the six spiral drill rods. It is also used to vertically guide the iron ring when it moves downward.

[0015] Preferably, the rotary drive assembly includes a rotating sleeve, multiple handles, an internal gear ring, and six gears. The rotating sleeve is rotatably fitted on the outside of an iron ring. The multiple handles are fixedly connected to the outside of the rotating sleeve in a ring with equal spacing. The internal gear ring is fixedly fitted on the inside of the rotating sleeve. The six gears are meshed in a ring with equal spacing on the inside of the internal gear ring. The bottom of the six gears is fixedly connected to the top of the corresponding auger rod.

[0016] Preferably, the protective vertical guide magnetic positioning assembly includes a magnetic ring, four vertical guide rods, a support ring, and a telescopic protective rubber sleeve. The magnetic ring is fixedly fitted on the outside of the annular groove, and the bottom of the magnetic ring is attracted to the top of the iron ring. The support ring is fixedly fitted on the bottom of the outer side of the annular groove. The four vertical guide rods are fixedly connected in a ring at equal intervals between the bottom of the magnetic ring and the top of the support ring. The iron ring is slidably fitted on the four vertical guide rods. The support ring is movably fitted on the bottom of the outer side of the six auger drill rods. The telescopic protective rubber sleeve is fixedly connected between the top of the support ring and the bottom of the iron ring. All six auger drill rods are located inside the telescopic protective rubber sleeve.

[0017] Preferably, the lowest point of the bottom inner wall of the water collection tray is flush with the bottom inner wall of the drain pipe.

[0018] Preferably, a circular perforation is provided between the inner wall of the top of the circular pressure groove and the inner wall of the bottom of the water collection tray, and the inner wall of the circular perforation is bonded and fixed to the outer side of the sealing sleeve.

[0019] Preferably, the bottom of the iron ring has six first circular holes in a ring shape, and two first bearings are fixedly sleeved in the first circular holes. The inner side of the inner ring of the first bearing is fixedly connected to the outer top of the corresponding spiral drill rod.

[0020] Preferably, the top of the support ring has six equally spaced movable perforations in a ring shape, and the auger drill rod is located in the corresponding movable perforation and does not contact the inner side of the movable perforation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By using a water collection tray, circular pressure groove, drainage pipe, central pipe and outer protruding edge to collect the slurry discharged from the borehole through the central pipe and guide it outward, the water collection tray is designed to prevent excessive drainage from causing sewage to flow directly outward around the water collection tray, thus ensuring the cleanliness and safety of the deep hole curtain grouting operation.

[0023] 2. Through the combination of the set water collection tray, circular pressure groove, drainage pipe, iron ring, spiral drilling rod, rotary drive assembly and guard vertical guide magnetic positioning assembly, it can drive six spiral drilling rods to drill into and out of the ground in an integrated manner, and fix and unlock the water collection tray. In conjunction with the water collection tray fixing method, the circular pressure groove and the outer edge of the convex edge are used to position and press the central pipe in an integrated manner, so as to achieve the effect of fixing and unlocking the water collection tray and the central pipe in an integrated manner. By fixing and unlocking the two in an integrated manner, the phenomenon that the external water collection tray is easy to fall off is avoided due to fixing only the central pipe, thus improving the stability of use.

[0024] 3. In addition, by driving six spiral drilling rods to drill into the ground simultaneously, there is no need for separate operation at multiple points, which improves the efficiency and convenience of multi-point fixing and unlocking.

[0025] This utility model, through a series of structures, can collect the slurry discharged upwards from the borehole through the central pipe and guide it outwards in a designated manner, avoiding excessive drainage that would cause sewage to flow directly around the water collection pan. This ensures a clean and safe environment for deep hole curtain grouting operations. It also facilitates the simultaneous fixing and unlocking of the water collection pan and the central pipe, avoiding the problem of the external water collection pan easily detaching when only the central pipe is fixed, thus improving the stability of use. Furthermore, by driving six spiral drilling rods to drill into the ground simultaneously in one piece, there is no need for multiple separate operations, improving the efficiency and convenience of multi-point fixing and unlocking.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 4 As shown in this embodiment, a deep-hole curtain grouting borehole drainage device includes:

[0033] The water collection tray 1 has an inclined inner wall at its bottom, a drain pipe 101 fixedly connected to its right side, a circular pressure groove 102 at its bottom, and an annular groove 104 with an open bottom on its outer bottom.

[0034] The sealing sleeve 103 is embedded and fixed between the top inner wall of the circular pressure groove 102 and the bottom inner wall of the water collection tray 1. The outer bottom of the sealing sleeve 103 is integrally provided with an outer edge that is bonded and fixed to the top inner wall of the circular pressure groove 102.

[0035] The central tube 2 is movably fitted inside the sealing sleeve 103. An outer edge protrusion 201 is integrally provided on its outer bottom and located in the circular pressure groove 102. The top of the outer edge protrusion 201 is in movable contact with the bottom of the outer edge. The sealing sleeve 103 is used to movably seal the outside of the central tube 2. The central tube 2 is used to align with the borehole for the external drill bit to pass through. The water collection plate 1 is used to contain and effectively collect the slurry discharged from the borehole through the central tube 2. The slurry is guided to the drainage pipe 101 by using its bottom inner wall as an inclined surface. The drainage pipe 101 is used to connect to the external drainage pipe to discharge the slurry to the designated collection point, avoiding excessive drainage volume that causes sewage to flow directly outside the water collection plate 1, and ensuring the cleanliness and safety of the deep hole curtain grouting operation.

[0036] An iron ring 3 is movably fitted on the outside of the annular groove 104;

[0037] The spiral drill rod 5 consists of six rods that are rotatably mounted at equal intervals in a ring at the bottom of the iron ring 3.

[0038] The rotary drive assembly is rotatably sleeved on the outside of the iron ring 3 and fixedly connected to the top of the six auger drill rods 5. The rotary drive assembly is used to drive the six auger drill rods 5 to rotate and to drive the iron ring 3 and the six auger drill rods 5 to move downward when pressure is applied by personnel. The six auger drill rods 5 rotate and move downward to drill into the ground for rooting and stabilizing positioning, which improves the stability of the water collection tray 1. When the water collection tray 1 is fixed, the outer edge 201 is used to press and fix the center pipe 2, so as to achieve the effect of positioning the water collection tray 1 and the center pipe 2 as a whole.

[0039] The guard vertical guide magnetic positioning component is installed on the outside of the annular groove 104 and connected to the iron ring 3. The guard vertical guide magnetic positioning component is used to magnetically fix and support the iron ring 3 when not in use, and to safely surround and protect the six spiral drill rods 5. It is also used to vertically guide the iron ring 3 when it moves down.

[0040] In this embodiment, the lowest point of the bottom inner wall of the water collection pan 1 is flush with the bottom inner wall of the drainage pipe 101. Taking advantage of the characteristic of water flowing downhill, it facilitates better drainage of slurry. A circular perforation is provided between the top inner wall of the circular pressure groove 102 and the bottom inner wall of the water collection pan 1. The inner wall of the circular perforation is bonded and fixed to the outer side of the sealing sleeve 103. The bottom of the iron ring 3 has six first circular holes in a ring shape. Two first bearings are fixedly fitted in the first circular holes. The inner side of the inner ring of the first bearing is fixedly connected to the top outer side of the corresponding spiral drill rod 5, which achieves the effect of rotating and installing the spiral drill rod 5.

[0041] Furthermore, such as Figure 2 , 3 As shown in Figure 4, the rotary drive assembly includes a rotating sleeve 602, multiple handles 603, an internal gear ring 601, and six gears 6. The rotating sleeve 602 is rotatably sleeved on the outside of the iron ring 3. The multiple handles 603 are fixedly connected to the outside of the rotating sleeve 602 in a ring with equal spacing. The internal gear ring 601 is fixedly sleeved on the inside of the rotating sleeve 602. The six gears 6 are meshed in a ring with equal spacing on the inside of the internal gear ring 601. The bottom of the six gears 6 is fixedly connected to the top of the corresponding auger rod 5.

[0042] In this embodiment, a second bearing is fixedly fitted inside the rotating sleeve 602. The inner side of the inner ring of the second bearing is fixedly fitted to the outer side of the iron ring 3, which serves to rotate the rotating sleeve 602 and prevent the rotating sleeve 602 from transmitting the rotational torque to the iron ring 3 when it rotates.

[0043] In this implementation scheme, through a rotating sleeve 602, multiple handles 603, an internal gear ring 601, and six gears 6, the operator rotates the opposing handles 603 with both hands, causing the rotating sleeve 602 to rotate. The rotating sleeve 602 drives the internal gear ring 601 to rotate, which in turn drives the six gears 6 meshing with it to rotate. The six gears 6 drive the six spiral drilling rods 5 to rotate synchronously. When the operator rotates the handles 603 and applies downward pressure, the handles 603, through the rotating sleeve 602, drive the iron ring 3 to move downward. The iron ring 3 then drives the six spiral drilling rods 5 to move downward. By rotating and moving downward, the six spiral drilling rods 5 drill into the ground to perform rooting and stabilizing positioning work, achieving the effect of fixing and supporting the water collection tray 1, reducing the phenomenon of displacement during use, and improving the stability of the water collection tray 1. When the water collection tray 1 is fixed, it is directly pressed and fixed to the center pipe 2 by the outer edge protrusion 201, achieving the effect of positioning the water collection tray 1 and the center pipe 2 as a whole.

[0044] Furthermore, such as Figure 2 , 3 As shown in Figure 4, the guard vertical guide magnetic positioning assembly includes a magnetic ring 301, four vertical guide rods 402, a support ring 4, and a telescopic guard rubber sleeve 401. The magnetic ring 301 is fixedly sleeved on the outside of the annular groove 104, and the bottom of the magnetic ring 301 is attracted to the top of the iron ring 3. The support ring 4 is fixedly sleeved on the bottom of the outer side of the annular groove 104. The four vertical guide rods 402 are fixedly connected in a ring at equal intervals between the bottom of the magnetic ring 301 and the top of the support ring 4. The iron ring 3 is slidably sleeved on the four vertical guide rods 402. The support ring 4 is movably sleeved on the bottom of the outer side of the six spiral drilling rods 5. The telescopic guard rubber sleeve 401 is fixedly connected between the top of the support ring 4 and the bottom of the iron ring 3. All six spiral drilling rods 5 are located inside the telescopic guard rubber sleeve 401.

[0045] In this embodiment, the top of the support ring 4 is provided with six movable through holes at equal intervals in a ring shape. The spiral drill rod 5 is located in the corresponding movable through hole and does not contact the inner side of the movable through hole, so as to allow the spiral drill rod 5 to move through. The top of the iron ring 3 is provided with four vertical guide holes that are respectively slidably fitted to the outer side of the corresponding vertical guide rod 402, so as to guide the iron ring 3 to slide vertically.

[0046] In this implementation scheme, the magnetic ring 301, four vertical guide rods 402, support ring 4, and telescopic protective sleeve 401 work together. When not in use, the magnetic ring 301 magnetically positions and supports the iron ring 3, and the telescopic protective sleeve 401 safely surrounds and protects the six auger rods 5, reducing the risk of injury from accidental contact with the auger rods 5 and improving safety when not in use. When the iron ring 3 is pressed down, it slides downward on the four vertical guide rods 402, which vertically guide the iron ring 3. As the iron ring 3 moves downward, it compresses the telescopic protective sleeve 401. When used later, rotating and pulling the handle 603 drives the rotating sleeve 602 and the iron ring 3 to rise, the telescopic protective sleeve 401 is pulled back upward to reset, once again concealing and protecting the six auger rods 5.

[0047] It should be noted that the magnetic ring 301 is a strong magnet, and the magnetic attraction it forms with the iron ring 3 is greater than the sum of the weights of the rotating sleeve 602, multiple handles 603, internal gear ring 601, six gears 6, six spiral drilling rods 5 and telescopic protective rubber sleeve 401. It can maintain the support of the iron ring 3 in the magnetic attraction state.

[0048] The usage method of this embodiment is as follows: When using the deep hole curtain grouting drilling and drainage device, firstly, the central tube 2 is inserted from bottom to top through the inside of the sealing sleeve 103 into the water collection pan 1. The outer edge 201 of the central tube 2 is inserted into the circular pressure groove 102. The central tube 2 is vertically aligned with the external drill hole. Then, the operator rotates the opposing handles 603 with both hands to make the rotating sleeve 602 rotate in the forward direction. The rotating sleeve 602 drives the internal gear ring 601 to rotate, and the internal gear ring 601 drives the six gears 6 meshing with it to rotate. The six gears 6 drive the six spiral drilling rods 5 to rotate synchronously. When the operator rotates the handles 603 and applies downward pressure, the handles 603 drive the iron ring 3 to move downward through the rotating sleeve 602. The iron ring 3 slides down on the four vertical guide rods 402. The iron ring 3 moves and separates from the magnetic ring 301, compressing the telescopic protective sleeve 401. When the iron ring 3 moves down, it also drives the six spiral drilling rods 5 to move down. The six spiral drilling rods 5 rotate and move down to drill into the ground for rooting and stabilizing, thus achieving the effect of fixing and supporting the water collection tray 1. The water collection tray 1 is restricted by the circular pressure groove 102 pressing and blocking the outer edge 201, thereby further fixing the central tube 2 as a whole. This achieves the effect of fixing the water collection tray 1 and the central tube 2 as a whole, thus achieving the effect of fixing both of them as a whole. This avoids the phenomenon that the external water collection tray 1 is easy to fall off due to fixing only the central tube 2, and improves the stability of use. In addition, by driving the six spiral drilling rods 5 to drill into the ground in a unified and synchronous manner, there is no need for multiple separate operations, which improves the efficiency and convenience of multi-point fixing.

[0049] The water collection basin 1 contains and collects the slurry discharged upwards from the borehole through the central pipe 2, and its bottom inner wall, being an inclined surface, guides the slurry to the drainage pipe 101. The drainage pipe 101 is used to connect to an external drainage pipe to supply slurry to a designated collection point, preventing excessive drainage from causing sewage to flow directly outside the water collection basin 1, thus ensuring a clean and safe environment for deep hole curtain grouting operations. For subsequent unlocking and disassembly, personnel rotate the handle 603 in the opposite direction to the rotating sleeve 602 and pull it upwards. This is completely opposite to the forward rotation and downward pressing of the rotating sleeve 602. At this time, the iron ring 3 changes to an upward movement, and the six spiral drilling rigs... Rod 5 rotates and gradually moves upwards into the annular groove 104. The iron ring 3 pulls the telescopic protective sleeve 401 upwards to reset. When the iron ring 3 moves upwards and contacts the magnetic ring 301, it is magnetically supported. The magnetic ring 301 provides magnetic positioning and support for the iron ring 3 when not in use. The telescopic protective sleeve 401 provides safe enclosure and protection for the six auger rods 5 when not in use. This achieves the effect of unlocking the six auger rods 5 simultaneously after use, and also achieves the effect of concealing and protecting the six auger rods 5 together after use or when not in use. This reduces the risk of injury caused by accidental contact with the auger rods 5 when not in use, and improves safety when not in use.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
