Description

Technical Field

[0001] This invention relates to the field of engineering construction technology, specifically to a construction method and device for providing vertical reaction force for exploration drilling rigs in a small space. Background Technology

[0002] Urban engineering surveying is a systematic project that requires a comprehensive understanding of the geological conditions and environmental factors surrounding the construction project. As urban development progresses, the scope of engineering projects expands, inevitably requiring passage through densely populated and building-rich areas. In densely built-up areas such as urban villages, the limited space between buildings and irregular building layouts make it difficult for drilling rigs to operate within confined spaces during the initial geological survey phase, thus hindering the accurate assessment of the geological conditions in that area.

[0003] In densely built-up areas, there is often a problem that the space is too small to meet the drilling rig operation. The traditional method is to modify and reduce the size of the drilling rig, but the space for size modification is limited, and because the drilling rig becomes lighter after modification, it cannot provide sufficient reaction force when the drilling depth is large.

[0004] The main measures currently taken to provide a reaction force include:

[0005] 1) Use sandbags, counterweights, and other heavy objects to directly press down on the drilling rig base;

[0006] 2) By adding levers to the drilling rig base and adding counterweights to the outside.

[0007] The two methods can provide limited reaction force and have poor stability, making it difficult to carry out deep drilling operations. Therefore, it is necessary to clear the site for drilling through temporary relocation and demolition, but this method is very expensive and increases construction costs and operation cycle.

[0008] Therefore, there is an urgent need for a drilling rig that can provide sufficient reaction force for engineering exploration drilling in confined spaces in densely built-up areas without changing the size of traditional drilling rigs, and solve the problem of poor equipment stability when drilling too deep, thereby reducing construction costs. Summary of the Invention

[0009] To address the aforementioned problems, the present invention aims to provide a construction method and corresponding device for providing vertical reaction force for exploration drilling rigs within a confined space, thereby solving the technical problems mentioned in the background section. To achieve the above objective, the present invention provides the following technical solution: a construction method for providing vertical reaction force for exploration drilling rigs within a confined space, comprising the following steps:

[0010] S1, confirm the construction area within the current confined space and the number of available surrounding buildings;

[0011] S2, placing the drilling rig base in the construction area and fixing the drilling rig on the drilling rig base;

[0015] S5, the telescopic device drives the support plate to clamp the drilling machine.

[0016] Preferably, when the two support plates clamp the drilling rig, the support plates are placed at the front end of the drilling rig support arm, and the support plates are in close contact with the drilling rig support arm and the drilling rig base.

[0017] Preferably, the telescopic device is driven by pneumatic, electric or hydraulic means, and each telescopic device can be controlled independently.

The use of hinged joints and rubber-lined boot plates enhances adaptability to wall surfaces and friction, improving stability.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0033] Please see Figure 1 The present invention provides a construction method for providing vertical reaction force for exploration drilling rigs in a small space as follows:

[0034] S1, confirm the construction area within the current confined space and the number of available surrounding buildings;

[0035] S2, place the drilling rig base 2 in the construction area and fix the drilling rig 10 on the drilling rig base 2;

[0036] S3, install boot plates 5 on the exterior walls 9 of the two buildings on both sides of the construction area;

[0037] S4, the support plate 1 at the front end of the telescopic device 6 is placed on both sides of the drilling rig 10;

[0038] S5, adjust the horizontal angle between the shoe plate 5 and the telescopic device 6 so that the support plate 1 is completely attached to both sides of the drilling rig 10;

[0039] S5, the telescopic device 6 drives the support plate 1 to clamp the drill rig 10.

[0040] When the boot plate 5 presses against the exterior wall 9 of the building, the boot plate 5 provides a positive pressure to the wall. At this time, the telescopic device 6, the support plate 1, the drill base 2, the drill 10 and the support arm 3 are all fixed due to the support of the boot plate 5.

[0041] When the two support plates 1 clamp the drilling rig 10, the support plates 1 are placed at the front end of the drilling rig support arm 3. The support plates 1 are in close contact with the drilling rig support arm 3 and the drilling rig base 2. The close contact on both sides, below and behind the drilling rig 10 makes the drilling rig 10 more stable during operation. At the same time, the limit at the bottom of the drilling rig 10 prevents the drilling rig 10 from drilling too deep. The friction provided by the clamping on both sides of the drilling rig 10 cannot offset the thrust brought by the drilling rig 10, which further improves the stability and firmness of drilling too deep.

[0042] When the drilling rig 10 is working normally, the pressure provided by the shoe plate 5 generates friction in the vertical direction, thereby providing a reaction force for the drilling process and ensuring that the drilling depth is enhanced.

[0043] Preferably, the boot plate 5 is covered with rubber material to increase the fit and contact area with the wall, reduce the vibration generated during the operation of the drilling rig 10, and avoid damage to the exterior wall 9 of the building.

[0044] The telescopic device 6 is driven by pneumatic, electric, or hydraulic power, and each telescopic device 6 can be independently controlled. The extension amount of the telescopic devices 6 on both sides of the drilling rig 10 can be adjusted, thereby adjusting the position of the drilling rig 10. The telescopic device 6 is hydraulically driven and is connected to the hydraulic pump station 8 via oil pipe 7. Operating the hydraulic pump station 8 can extend or retract the telescopic device 6, and the rubber-fitted shoe plate 5 extends or retracts together with the telescopic device 6.

[0045] The boot plate 5 is a plate-shaped object made of rigid material. The contact surface of the boot plate 5 has the same shape as the exterior wall surface 9 of the building. The surface material of the contact surface of the boot plate 5 is rubber, which is used to increase the friction between the boot plate 5 and the exterior wall surface 9 of the building.

[0046] The telescopic device 6 is driven by a hydraulic gear pump, and the length of two or more telescopic rods can be adjusted to accommodate construction areas with unequal distances between the exterior walls 9 of the building.

[0047] The boot plate 5 is connected to the telescopic device 6 via a spherical hinge. The lateral adjustment range of the hinge 4 is -60° to 60°, which increases the adaptability to the exterior walls 9 of various buildings. If the construction area cannot be passed between the exterior walls of two buildings, the angle of the hinge 4 can be adjusted so that the telescopic device 6 can pass through the construction area and clamp the drilling rig 10.

[0048] In another preferred embodiment, the boot plate 5 has a cavity inside, which is hinged to the telescopic device 6 4.

[0049] This invention provides a device for providing vertical reaction force for exploration drilling rigs within a small space, and offers a technical solution:

[0050] At least one boot plate 5 is provided on an exterior wall 9 of a building, and the boot plate 5 between two exterior walls 9 of a building is movably connected to an expansion joint 6, which is set perpendicular to the exterior wall 9 of the building.

[0051] The telescopic device 6 is connected to at least one support plate 1 at its front end. The support plate 1 is located above the drill base 2. The drill 10 and the drill support arm 3 are fixedly connected above the drill base 2. The drill 10 is set between the two support plates 1, and the drill support arm 3 is located behind the two support plates 1.

[0052] By utilizing the building's limited space, the horizontal pressure is applied to increase the vertical friction by using the building's exterior wall 9 as a support, while simultaneously stabilizing the drilling rig 10 equipment.

[0053] This invention can be applied in confined spaces in densely built areas, using building walls to provide support, turning constraints into opportunities, and "turning waste into treasure." It mainly overcomes the problems of insufficient counterweight and instability of the drilling rig 10 in narrow spaces, and enhances the counterweight capacity, stability and drilling capability of the drilling rig 10.

[0054] This invention allows for adjustment of the position of the drilling rig 10 by varying the extension amount of the telescopic device 6, increasing the spatial flexibility and applicability of the drilling rig 10. The use of the hinge 4 and the rubber-coated shoe plate 5 enhances adaptability and friction against the building's exterior wall 9, improving stability; it ensures drilling operations in confined spaces and that the depth meets exploration requirements, reducing the possibility of temporary relocation or demolition, thereby significantly reducing potential construction costs.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects. The scope of the invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within the invention, and no reference numerals in the claims should be regarded as limiting the scope of the claims.
