For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0033] This utility model provides a noise reduction shed for foundation pit construction. It is constructed by setting two parallel guide drainage channels and arranging multiple support frames at intervals on the guide drainage channels. The top of the support frames is fixedly covered with a dustproof and noise reduction cloth. The support frames can slide along the length of the guide drainage channels to cover or open the foundation pit, which is convenient for dustproof and noise reduction construction in the foundation pit and also convenient for placing other construction equipment in the foundation pit.

[0034] like Figure 1 , Figure 2 As shown, the noise reduction shed for foundation pit construction includes two relatively parallel guide drainage channels 1. The top of each drainage channel 1 has a trough-like structure. The guide drainage channels 1 span opposite ends of the foundation pit 2. Multiple support frames 3 are arranged at intervals between the two guide drainage channels 1. The ends of the support frames 3 are bent downwards and respectively installed within the trough-like structure of the guide drainage channels 1, and can slide with the guide drainage channels 1. In this embodiment, as... Figure 3 As shown, a sliding wheel 8 is provided at the bottom of the downward bending section of the support frame 3, and the support frame 3 slides with the guide drainage groove 1 through the sliding wheel 8.

[0035] The top of the supporting frame 3 is fixedly covered with a dustproof and noise-reducing cloth 4, such as Figure 4 As shown, the dustproof and noise-reducing cloth 4 has at least one sound insulation layer 401, and a waterproof layer 402 is provided on top of the sound insulation layer 401. In this embodiment, the sound insulation layer 401 is made of sound-absorbing fabric, and the materials used to make the sound-absorbing fabric mainly include cotton, polyester fiber, glass fiber, ceramic fiber, etc. Among them, polyester fiber is one of the most commonly used materials because it has good sound absorption effect and low cost. The waterproof layer 402 is made of plastic film, which can play a role in waterproofing and dust reduction.

[0036] The edges of the dustproof and noise-reducing cloth 4 on both sides extend above the guide drainage channel 1, which facilitates the flow of water from the top of the dustproof and noise-reducing cloth 4 into the guide drainage channel 1 for discharge.

[0037] The noise reduction shed used for foundation pit construction also includes a drive structure, which drives the support frame 3 to slide along the length of the guide drainage channel 1 to cover or open the opening of the foundation pit 2.

[0038] In this embodiment, as Figure 2 , Figure 5 As shown, the drive structure includes a rope winder 12, a fixed pulley 6, and a pulling rope 7.

[0039] The winding device 12 is rotatably installed at one end of the guide drainage groove 1, and can wind or unwind the pulling rope 7 by rotating. The fixed pulley 6 is arranged at the other end of the guide drainage groove 1 opposite to the winding device 12. The pulling rope 7 is wound on the winding device 12 in opposite directions at two ends, and the part between the two ends of the pulling rope 7 is arranged around the fixed pulley 6. In this way, when the winding device 12 rotates, one end of the pulling rope 7 is tightened and the other end is loosened. The fixed position of the pulling rope 7 is fixedly connected to the support frame 3 near the side of the fixed pulley 6 through the fixed clasp 11. Specifically, the pulling rope 7 becomes two relatively arranged parts after being wound around the fixed pulley 6, and the two parts correspond to the two ends respectively. The fixed position of one part is fixedly connected to the support frame 3 through the fixed clasp 11. When the winding device 12 rotates, the part fixed to the support frame 3 moves towards the fixed pulley 6, thereby covering the opening of the foundation pit 2, and the other part moves away from the fixed pulley 6 at this time.

[0040] Therefore, the pulling rope 7 can be used to pull the support frame 3 to reciprocate along the guide drainage groove 1, thereby covering or opening the opening of the foundation pit 2 by the dustproof and noise reduction cloth 4.

[0041] Further, in order to ensure the drainage effect of the guide drainage groove 1, the height of the two ends of the guide drainage groove 1 is lower than the height of the middle part. In this embodiment, the guide drainage groove 1 is in an arc shape with the middle part arched upwards, thereby facilitating drainage to the outside of the two ends.

[0042] Further, in order to realize directional drainage, the two ends of the guide drainage groove 1 are respectively connected with the water collecting groove 5 for collecting water discharged from the guide drainage groove 1, and then the water collecting groove 5 is connected with an external water collecting device to transport the water away from the foundation pit 2, thereby avoiding affecting the stability of the foundation pit 2.

[0043] Further, the height of the two ends of the support frame 3 is lower than the height of the middle part. In this embodiment, the support frame 3 is in an arc shape with the middle part arched upwards, thereby facilitating drainage of the dustproof and noise reduction cloth 4 to the guide drainage groove 1 on both sides.

[0044] In this embodiment, since it is used for subway construction, the foundation pit 2 is excavated along the extension direction of the length of the subway line. In order to facilitate the use of the device, the noise reduction shed for the construction of the foundation pit 2 further comprises a guide rail 9 arranged along the length direction of the excavation of the foundation pit 2. The guide rail 9 is arranged on the top of the two sides of the foundation pit 2 in a relative manner. The bottom of the water collecting groove 5 is provided with a moving wheel 10 which can move along the guide rail 9 to change the position of the foundation pit 2 covered by the dustproof and noise reduction cloth 4. When a section of the foundation pit 2 is constructed, the guide rail 9 can be advanced by a distance to facilitate the construction of the next section of the foundation pit 2.

[0045] It can be understood that the above description is only exemplary, and the embodiments of the application are not limited thereto.

[0046] The above is only a preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model are within the protection scope of the utility model.
