Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for building construction, specifically a movable sound insulation and noise reduction and dust control cover device used above rock breaking construction inside a working well. Background Technology

[0002] Currently, the methods used for rock breaking inside working shafts include blasting, hydraulic breakers, and pneumatic rock drills. Given the stringent requirements for construction schedules, construction cannot be interrupted arbitrarily. Consequently, all of these methods generate significant noise and dust, disrupting the surrounding environment and impacting the lives of nearby residents. Finding a way to meet sound insulation and dust control requirements while maintaining uninterrupted construction and minimizing environmental disturbance remains a challenging technical problem. Utility Model Content

[0003] To address the above problems, this utility model provides a movable sound insulation and dust control cover device. The working well is divided into working areas, and this device separates the construction area from the non-construction area, ensuring continuous, low-interference rock drilling and improving work efficiency.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows: A movable sound insulation and dust control cover device includes a rock wool sound insulation cover for sealing un-constructed openings and a transparent acrylic cover for covering construction openings. Both the rock wool sound insulation cover and the transparent acrylic cover include a frame structure and a panel structure. The frame structure is sized to fit the opening of the working well. Multiple lifting points are welded to the frame structure. The panel structure is anchored to the frame structure with bolts, and the four corner irons are anchored to the frame structure with bolts. The transparent acrylic cover includes covers with and without ladder cages inside the well. The frame structure of the cover with ladder cages inside the well has an opening corresponding to the position of the ladder cage inside the construction well, and an acrylic plate of a corresponding shape is connected to it.

[0005] The frame structure is supported by channel steel on all four sides, and welded angle steel is used as horizontal and vertical ribs for internal support. Welded I-beams are used as back ribs. The panel structure is fixed by bolts into the angle steel, and the angle irons around the panel structure are bolted into the channel steel.

[0006] The panel structure includes an acrylic board and a rock wool board, which are used for the transparent acrylic cover and the rock wool soundproof cover, respectively.

[0007] The rock wool board is an inorganic fiber board made of basalt through high-temperature melting and processing, while the acrylic board is a thermoplastic plastic polymerized from methyl methacrylate monomers.

[0008] Both types of cover plates are 9.5 meters long and 7 meters wide. The corners of the cover plates are welded, and the channel steel is connected by welding.

[0009] The lifting points are welded to the long side of the frame structure, made of round steel, and the welding length is ≥0.3m.

[0010] This utility model has the following advantages: 1. The main structure of the cover plate is made of two materials: rock wool board and acrylic board. The size depends on the size of the working well opening. The internal structure is supported by angle steel as the main frame, and metal lifting rings are welded around the perimeter for easy lifting and movement.

[0011] 2. The rock wool board cover is wavy, and the sound waves are refracted and reflected multiple times to reduce energy. Noise monitoring facilities are set up at the edge of the working well. After comparing the effect before and after the cover is on, the noise effect is significantly reduced.

[0012] 3. Acrylic cover plates have good light transmittance, which can improve the lighting conditions underground, making it easier for construction personnel to clearly observe the surrounding environment. They are also relatively lightweight and easy to move.

[0013] In summary, this utility model enables the rock breaking construction of the working well to greatly reduce the transmission of rock breaking noise and dust while ensuring lighting, effectively achieving the goal of eliminating noise and dust pollution. At the same time, it avoids the impact on nearby residential areas, avoids the risks of complaints and obstruction of construction by the public, and achieves environmental protection while ensuring controllable construction progress.

Detailed Implementation

[0016] Example

[0017] A movable sound insulation and dust control cover device includes a rock wool sound insulation cover 9 for sealing un-constructed openings and a transparent acrylic cover 10 for covering construction openings; both the rock wool sound insulation cover 9 and the transparent acrylic cover 10 include a frame structure and a panel structure; the panel structure includes, for example,... Figure 2.1 Rock wool board 8 shown and as Figure 2.2 The acrylic sheet 6 shown is used for the transparent acrylic cover 10 and the rock wool sound insulation cover 9, respectively.

[0018] like Figure 1 As shown, the size of the skeleton structure is adapted to the size of the working well opening, with a length of 9.5 meters and a width of 7 meters. The skeleton structure uses channel steel 1 as the frame on all four sides, welded angle steel 2 as horizontal and vertical ribs for internal support, and welded I-beams 3 as back ribs. The channel steel 1 is connected and closed by welding.

[0019] Multiple lifting points 5 are welded to the frame structure; the lifting points 5 are welded to the long side of the frame structure, made of round steel, and the welding length is ≥0.3m. The panel structure is anchored to angle steel 2 by bolts 4, and the four corner irons are anchored to channel steel 1 by bolts 4; the corners of the cover plate are welded.

[0020] The transparent acrylic cover plate 10 includes a cover plate 101 with a ladder cage inside the well and a cover plate 102 without a ladder cage inside the well. The skeleton structure of the cover plate 101 with a ladder cage inside the well has a working well ladder cage opening 7 corresponding to the position of the ladder cage inside the construction well, and an acrylic plate 6 with a corresponding shape is connected to it.

[0021] The rock wool board 8 is an inorganic fiber board made of basalt through high-temperature melting and processing, and the acrylic board 6 is a thermoplastic plastic polymerized from methyl methacrylate monomers.

[0022] like Figure 6 As shown, this utility model is applied to a project involving a three-hole working well. Therefore, one rock wool soundproof cover plate 9, one cover plate 101 with a ladder cage inside the well, and one cover plate 102 without a ladder cage inside the well are manufactured. The size of the cover plate is adapted to the size of the working well opening and completely covers the top of the working well. There is no ladder cage inside the construction well opening, and the cover plate 102 without a ladder cage inside the well is used above it to ensure good lighting effect inside the well. The top of the unconstructed well opening is covered with the rock wool soundproof cover plate 9. When construction is carried out in other well openings, the corresponding cover plate is also replaced. One of the well openings contains a ladder cage, and the rock wool cover plate is reserved for the position of the ladder cage. The top of the construction well opening is the cover plate 101 with a ladder cage inside the well. Without affecting the personnel access, noise and dust are reduced to the greatest extent.
