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 drilling structure for vertical holes in rock mass near a building foundation pit for dust prevention and noise reduction. Background Technology

[0002] With the rapid advancement of modern urbanization, a large number of high-rise buildings are being constructed, and the demand for urban land is becoming increasingly tight. The development of land near mountains and adjacent to existing buildings is increasing. At the same time, in order to meet the demand for underground parking, the number of basement floors in buildings is gradually increasing, and the excavation depth of foundation pits 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.

[0003] Typically, rock excavation for foundation pits requires drilling a large number of saw holes, which generates significant noise and dust, severely disrupting and affecting the normal lives of residents in nearby buildings. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling structure for vertical holes in rock mass of adjacent building foundation pits that prevents dust and reduces noise, aiming to solve the problem of strong noise and dust generated when drilling saw rope holes in the prior art.

[0026] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0027] The vertical drilling structure for dust prevention and noise reduction in the rock mass of the adjacent building rock foundation pit includes a down-the-hole hammer drill 11, a wire saw hole 12 for drilling through the down-the-hole hammer drill 11, and a protective shed 1 covering the construction area. The down-the-hole hammer drill 11 is covered by the protective shed 1. An entrance 2 is provided on one side of the protective shed 1. A ventilation opening 3 is provided on the protective shed 1. A skylight 4 is provided on the top of the protective shed 1. The bottom of the protective shed 1 is connected and fixed to the ground through multiple mounting bases 13. Multiple spray devices 24 are provided on the top inside the protective shed 1.

[0028] By covering the construction work with a protective shed 1 equipped with a spray device 24, a relatively sealed aperture can be formed, which can effectively limit the spread of dust and facilitate the treatment of dust generated during construction within the protective shed 1, thereby ensuring a healthy working environment while reducing adverse effects on surrounding buildings.

[0029] Specifically, in this embodiment, ventilation equipment is provided at the three ventilation openings, and the ventilation equipment is a T40-11 axial flow fan.

[0030] The ventilation equipment ensures proper ventilation within the protective shed, thereby guaranteeing a healthy working environment.

[0031] Specifically, in this embodiment, explosion-proof glass is installed at four points on the skylight, providing both light transmission and sound insulation.

[0032] Specifically, in this embodiment, the protective shed 1 uses aluminum composite panel as the sealing plate 5, aluminum alloy frame 9 and copper square tube 10 as the connecting frame.

[0033] Specifically, in this embodiment, the outer surface of the protective shed 1 sealing plate 5 is an aluminum-plastic corrugated plate 8, the inner surface of the protective shed 1 is an aluminum-plastic flat plate 7, and fireproof rock wool 6 is filled between the aluminum-plastic corrugated plate 8 and the aluminum-plastic flat plate 7.

[0034] By installing fireproof rock wool 6, aluminum-plastic corrugated board 8 and aluminum-plastic flat board 7, the sound insulation and fireproof performance of the protective shed 1 can be guaranteed, effectively blocking the spread of construction noise.

[0035] Specifically, in this embodiment, the aluminum-plastic corrugated plate 8 is provided with multiple raised strips at intervals. The raised strips are 15mm higher than the surface of the aluminum-plastic corrugated plate 8, and the distance between two adjacent raised strips is 76mm.

[0036] Specifically, in this embodiment, the mounting base 13 has a mounting groove 16 for inserting the protective canopy 1 sealing plate 5, and the mounting base 13 has four through holes 14 arranged in a matrix.

[0037] With the installation slot 16, the mounting base 13 can be fixed to the ground by passing the fixing rivet through the through hole 14, and then the protective canopy 1 sealing plate 5 can be inserted into the installation slot 16 on the mounting base 13 to achieve quick installation and fixation of the protective canopy 1.

[0038] Specifically, in this embodiment, a transmission cavity 22 is provided in the mounting base 13, and a transmission slider 19 is slidably installed in the transmission cavity 22. A top block 21 is provided at one end of the transmission slider 19 that passes through the mounting base 13 and extends into the mounting groove 16. A threaded rod 23 that is threadedly connected to the transmission slider 19 is rotatably installed in the transmission cavity 22.

[0039] With the threaded rod 23 and the top block 21, after the protective canopy 1 sealing plate 5 is inserted into the mounting groove 16, the threaded rod 23 can be rotated to drive the top block 21 on the transmission slider 19 to press against the protective canopy 1 sealing plate 5 through the threaded screwing relationship, thereby realizing the connection and fixation between the protective canopy 1 sealing plate 5 and the mounting base 13.

[0040] Specifically, in this embodiment, the threaded rod 23 has a protruding mating protrusion 15 at one end of the mounting base 13, and the transmission slider 19 has a threaded hole 20 that matches the threaded rod 23.

[0041] By setting the mating protrusion 15, the threaded rod 23 can only be rotated by a specific tool, preventing others from accidentally touching it and causing the connection between the protective canopy 1 sealing plate 5 and the mounting base 13 to loosen.

[0042] Specifically, in this embodiment, the transmission cavity 22 has two mutually symmetrical limiting grooves 17, and the transmission slider 19 has two limiting sliders 18 that are slidably installed in the limiting grooves 17.

[0043] By the interaction between the limiting slide groove 17 and the limiting slider 18, the movement range of the transmission slider 19 can be limited.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
