Description

Technical Field

[0001] The invention relates to the field of foundation construction, and in particular to a top-fixed water drill device, an application method thereof and an excavation system. Background Art

[0002] At present, for the excavation of pipe jacking working shafts in rock geological conditions, the construction method generally adopted is blasting construction. This type of construction method has high cost, high risk factor, and inconvenient transportation. At the same time, during the blasting process, it may affect the stability of the surrounding rock formations and destroy the integrity of the surrounding rock formations. Excavation using pneumatic picks and manual rock digging methods has problems such as slow excavation speed and high cost.

[0003] Water drills can drill hard concrete, that is, medium-weathered and slightly-weathered rock formations. The working principle of water drills is used to cut and crush the rock formation layer by layer, thereby realizing the excavation of the rock formation. The water drill is used to split the entire rock formation to obtain several smaller rock formations. According to the integrity of the rock formation, a hand drill is used to drill holes in the remaining rock cores. Then, two hammers are used to hit the steel wedge or pneumatic pick to split the middle rock mass. The rock is pulled apart along the plumb surface and sheared from the bottom. The split rock blocks are taken out, thereby realizing the excavation of the jacking working well.

[0004] However, the installation of water drill is inconvenient and time-consuming, which limits the efficiency of using water drill to excavate rock formations. Summary of the invention

[0005] In view of the technical problems existing in the prior art, the purpose of the present invention is to provide an efficient and convenient top-fixed water drill device and its application method and excavation system.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A top-fixed water drill device comprises a positioning structure, a supporting structure and a receiving structure; the supporting structure is a telescopic structure, spanning a working well, and the number of the supporting structures is at least two groups; the top of the water drill is installed on the receiving structure, the receiving structure spans across the supporting structures and is adjustably connected to the plane position of each supporting structure, and the positioning structure embedded in the inner wall of the working well is installed on the supporting structure.

[0008] After adopting this structure, the positioning structure is embedded in the working well and is firmly installed. The position of the receiving structure is adjustable, which is convenient for the water drill to drill different coring points.

[0009] As a preference, each group of support structures includes a first support rod, two connecting screw threads, and two second support rods. Both ends of the first support rod are telescopically connected to the second support rods through the connecting screw threads, and the thread directions of the two connecting screw threads are opposite. After adopting this structure, the support structure can be telescoped through the connecting screw threads, and the positioning structure will be telescoped accordingly, which is convenient to use and can be used for working wells with different diameters.

[0010] As a preference, the receiving structure is a square timber, which is detachably connected to the support structure through a steel strand, and the position of the square timber is adjusted by the disassembly and assembly of the steel strand; the square timber is arranged below the support structure. After adopting this structure, it can provide a top support point for the diamond core drill at different coring positions, making the diamond core drill not easy to tilt left and right, and is convenient for disassembly and assembly.

[0011] As a preference, the positioning structure is divided into an in-well positioning part and a wellhead positioning part; the in-well positioning part is installed on the support structure to form an internal fixing device for deeper working wells, and the support structure is located inside the working well across the working well; the wellhead positioning part is installed on the support structure to form an external fixing device for shallower working wells, and the support structure is located at the top of the working well across the working well. The above-mentioned shallower working well refers to a working well with an excavation depth not exceeding 2m, and the deeper working well refers to a working well with an excavation depth exceeding 2m. After adopting this structure, the internal fixing device and the external fixing device are used for working wells with different depths, and the application range is wide.

[0012] As a preference, the wellhead positioning part includes a connecting rod and a clamping joint. The clamping joint is installed at the lower end of the connecting rod, and the upper end of the connecting rod is fixed on the support structure; each group of support structures is equipped with two wellhead positioning parts; the in-well positioning part includes a tapered head, and tapered heads are installed at both ends of each group of support structures.

[0013] As a preference, the internal fixing device and the external fixing device respectively have independent support structures, so that the internal fixing device and the external fixing device are independent of each other; or the internal fixing device and the external fixing device share the support structure to form an integrated structure that is used for both the internal fixing device and the external fixing device.

[0014] An application method of a top-fixed diamond core drill device, adopting any of the above-mentioned top-fixed diamond core drill devices for the excavation of a pipe jacking working well in rock geology, includes the following steps:

[0015] Step 1, arrange coring points; Step 2, fix and position the diamond core drill with the top-fixed diamond core drill device; Step 3: Operate the diamond core drill for drilling and excavation until all coring points are drilled; Step 4: Divide and process the overall rock formation obtained after drilling; Step 5: Remove the slag.

[0016] After adopting this method, compared with blasting construction, the above method is safer, the water drill is easy to install, and the excavation speed is fast.

[0017] As a preferred method, in step 2, a fixing hole is drilled in advance on the inner wall of the top pipe working well, and two external fixing devices or internal fixing devices are used to extend the support structure until the positioning structure is inserted into the fixing hole to complete the fixing of the device, and then the receiving structure is installed below the supporting structure, and connected to the supporting structure through a steel strand, so that the receiving structure is against the top of the water drill; when the depth of the working well does not exceed 2m, an external fixing device is used, and when the depth of the working well exceeds 2m, an internal fixing device is used; in step 3, after drilling a coring point, the steel strand is loosened, and the position of the water drill and the receiving structure is adjusted according to the position of the next coring point, and the receiving structure is fixed again with the steel strand, and then the water drill is operated to drill until all the coring points are drilled. After using this method, after drilling once, the water drill of multiple coring points can be fixed, and the position of the water drill is easy to adjust and can be quickly disassembled and assembled.

[0018] As a preferred method, in step one, the specific operation is to measure and lay out, determine the center point of the working well excavation, determine the radius of the working well excavation, draw a circle with the center point of the working well as the base point, and when arranging the coring points, indicate the inner and outer margins of the coring points according to the drawn range of the top pipe working well; in step four, the specific operation is to first perform water drilling and segmentation on the remaining overall rock formation, then use a hand drill to drill holes in the remaining rock core, and then use two hammers to hit the steel wedge or pneumatic pick to split the middle rock mass until the rock is pulled apart along the plumb surface and shear fracture occurs from the bottom, and then take out the split rock blocks; in step five, the specific operation is to load the taken out rock blocks into the hopper and use an electric winch to remove the slag. After adopting this method, the surrounding rock formations are less affected when the rock mass is segmented, the required tools are simple, and the cost is low.

[0019] A top-fixed water drill excavation system adopts any of the above-mentioned top-fixed water drill devices, including a water drill, an electric hoist, and a gantry. The top of the water drill is fixed in a working well by the top-fixed water drill device, and the electric hoist is installed above the working well through the gantry.

[0020] In general, the present invention also has the following advantages:

[0021] A top-fixed water drill device in the present invention is used in the excavation of rock working wells and can completely replace traditional blasting construction. It has high safety and low cost. Through top fixation, the time consumed in installing the water drill is reduced. Compared with other fixing device methods, this fixing device method is suitable for any well and has the advantages of repeated use and rapid disassembly and assembly, and the reusability of the integrated structure is high. At the same time, compared with traditional manual pneumatic pick excavation, the required construction speed has been greatly improved, and it can be widely adapted to medium-weathered and slightly-weathered rock geology, and is an efficient and convenient construction method.
