Abstract
Description
Technical Field
[0001] This utility model patent relates to the technical field of construction structure for dust prevention and noise reduction in rock mass, specifically to a construction structure for wire sawing for dust prevention and noise reduction in rock mass of adjacent building foundation pits. Background Technology
[0002] With the rapid advancement of modern urbanization, a large number of high-rise buildings are being constructed, leading to increasingly tight urban land demand. Development of land near mountains and adjacent to existing buildings is on the rise. At the same time, to meet the demand for underground parking, the number of basement floors in buildings is gradually increasing, and the depth of foundation pit excavation is getting deeper and deeper. When the rock strata at the foundation pit site are shallow, thick, and strong, the foundation pit construction faces a lot of hard rock breaking and excavation. The noise and dust generated during the construction process seriously interfere with and affect the normal lives of residents in nearby buildings.
[0003] Typically, rock excavation for foundation pits employs techniques such as open blasting, static blasting, and carbon dioxide fracturing. Open blasting generates significant noise and dust, and may produce flying rocks, posing a high risk. Static blasting involves drilling blasting holes and filling them with explosives for expansion and fracturing. This requires drilling numerous blasting holes, generating considerable noise and dust pollution. Furthermore, the subsequent de-blasting and fracturing of the rock mass after static blasting continues to produce significant noise. Wire sawing and carbon dioxide fracturing techniques require drilling numerous wire saw holes, and the separated rock mass needs secondary fracturing after fracturing, generating substantial noise and dust during the construction process. All three traditional construction techniques generate significant noise and dust, causing pollution and adverse effects on the surrounding environment. Therefore, how to ensure the efficiency of rock foundation pit excavation while minimizing the adverse impact on surrounding buildings and ensuring a green and environmentally friendly construction environment is an urgent problem to be solved in the excavation of rock foundation pits near nearby buildings. Utility Model Content
[0004] The purpose of this utility model is to provide a construction structure for dust prevention and noise reduction of wire saw construction in rock foundation pits near buildings, aiming to solve the problem of a large amount of dust and noise during wire saw construction in the prior art.
[0005] This utility model is implemented as follows: a wire saw construction structure for dust prevention and noise reduction in rock mass near a building's foundation pit. Its features include a wire saw cutting mechanism, a saw rope, and a water injection pipe. The wire saw cutting mechanism is used to cut the rock mass from multiple sides. Two horizontal saw rope holes and one vertical saw rope hole are opened on the surface of the rock mass. The three saw rope holes are designated as holes A, C, and E. A water injection pipe is installed at the entrance of the saw rope into the saw rope hole. Water supplied by the water injection pipe can enter the saw rope hole along with the saw rope and soak the saw rope channel, forming a water-cooled cutting operation.
[0006] Preferably, holes A, C, and E extend into the rock mass and converge to form point F, with holes A, C, and E forming a three-hole connection.
[0007] Preferably, the saw rope passes through the channel CFE formed by holes C and E, and the cutting direction is from the inside to the outside to form a horizontal cutting surface at the bottom of the rock mass.
[0008] Preferably, the saw rope passes through holes A and C, as well as through the saw rope channels CFA and AFE formed by holes A and E, to cut the rock mass, forming two vertical cutting surfaces.
[0009] Preferably, the wire saw cutting machine is model LKH.75 wire saw cutting machine, and the wire saw cutting mechanism consists of a wire saw motor, a travel motor and a travel track.
[0010] Preferably, the saw rope cutting mechanism performs horizontal cutting first and then vertical cutting during the rock cutting process.
[0011] Preferably, the two horizontal saw wire holes are formed using an XQ100B type horizontal lightweight down-the-hole drill, and the diameter of the horizontal saw wire holes is 90mm.
[0012] Preferably, the vertical sawing wire hole is formed using an HW-420 down-the-hole hammer drill, and the diameter of the vertical sawing wire hole is 90mm.
[0013] Preferably, the sawing wire is a diamond wire inlaid with granular diamonds.
[0014] Preferably, the wastewater generated during the sawing of the wire can be recycled after sedimentation.
[0015] Compared with existing technologies, the dust-proof and noise-reducing wire saw construction structure for adjacent building rock foundation pits provided by this utility model, through the cooperation of a wire saw channel formed by two horizontal and vertical wire saw holes, a wire saw cutting mechanism, and a water injection pipe, allows water to be injected into the wire saw holes through the water injection pipe. This allows the water to flow along with the high-speed running wire and enter the entire wire saw hole, soaking the entire wire saw channel to form a water-cooled cutting operation. This can cool the diamond on the wire saw during operation, ensuring the service life of the wire saw. At the same time, it can promptly degrade the dust generated during rock cutting and reduce the noise generated during cutting to a certain extent. Attached Figure Description

The saw rope 3 passes through the saw rope channels of holes A and C, as well as the channels CFA and AFE formed by holes A and E, to cut, forming two vertical cutting surfaces of the rock mass 1.
[0028] The CEF, CFA, and AFE channels allow the saw wire 3 to pass through and cut the rock mass 1.
[0029] Specifically, in this embodiment, the wire saw cutting machine is model LKH.75 wire saw cutting machine, and the wire saw cutting mechanism 2 consists of wire saw motor 6, walking motor 7 and walking track 8.
[0030] Specifically, in this embodiment, during the cutting process of the rock mass 1, the saw rope 3 first performs horizontal cutting and then vertical cutting, which can avoid the rock breaking and pressing down on the saw rope 3 when cutting on the ground after side cutting.
[0031] Specifically, in this embodiment, the two horizontal saw wire holes 4 are formed using an XQ100B type horizontal lightweight down-the-hole drill, and the diameter of the horizontal saw wire holes 4 is 90mm.
[0032] Specifically, in this embodiment, the vertical sawing wire hole 4 is formed using an HW-420 down-the-hole hammer drill, and the diameter of the vertical sawing wire hole 4 is 90mm.
[0033] Specifically, in this embodiment, the sawing rope 3 is a diamond rope inlaid with granular diamonds, which can grind the rock at high speed during construction by using the diamond particles inlaid on the sawing rope 3, thereby realizing the cutting process.
[0034] Specifically, in this embodiment, the wastewater generated during the cutting of the saw rope 3 can be recycled after sedimentation, making the construction more energy-efficient and environmentally friendly, and controlling the construction cost to a certain extent.
