Description

Technical Field

[0001] This invention relates to the field of construction noise isolation technology, and in particular to a modular nighttime construction noise isolation device and method. This device is suitable for noise control during nighttime construction when the construction site is located near sensitive areas such as residential areas. Background Technology

[0002] Many construction sites are located within cities or near residential areas, making them sensitive to nighttime noise. Furthermore, some construction projects that generate noise during operation, such as bored pile drilling, require continuous operation for extended periods; otherwise, serious quality accidents could occur. Therefore, construction projects in cities inevitably involve nighttime work and noise generation, and noise control measures must be implemented to ensure that nearby areas are not affected. Currently, sound insulation measures for construction sites fall into two categories: source control and propagation path control. Source control involves employing more expensive low-noise construction technologies or simply halting construction. Propagation path control includes erecting walls around the construction site or constructing dedicated soundproof rooms or sheds at the noise source. These sound insulation facilities typically use sound-insulating panels combined with sound-absorbing linings, resulting in their heavy weight, large size, and difficulty in installation, dismantling, transportation, and storage, posing challenges to their use. Summary of the Invention

[0003] This invention addresses the problems and shortcomings of existing technologies by providing a novel modular nighttime construction noise isolation device and method, which significantly improves the effectiveness and flexibility of nighttime noise control measures at construction sites while effectively controlling costs.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention provides a modular nighttime construction noise isolation device, characterized in that it includes multiple sound insulation modules placed in predetermined installation positions. Each sound insulation module includes a base storage box, and an uninflated flexible inflatable sound insulation wall is placed inside the base storage box. The bottom of the flexible inflatable sound insulation wall is fixedly connected to the base storage box. An air valve is connected to the flexible inflatable sound insulation wall. At least one cable is fixed to both sides of the flexible inflatable sound insulation wall, and a ground anchor is fixed to the bottom of the cable. Ear plates with bolt holes are fixed to both ends of the base storage box.

[0006] The fixed connection between two adjacent sound insulation modules is as follows: the bolt holes of the end ear plate of one sound insulation module are aligned vertically with the bolt holes of the end ear plate of another sound insulation module, and then the connecting bolts are passed through and locked by the fastening nuts, so that multiple sound insulation modules are connected in sequence.

[0007] Each of the sound insulation modules is inflated using an air valve after being removed from the base storage box to form a noise isolation device.

[0008] This invention also provides a method for isolating construction noise at night, characterized in that it utilizes the aforementioned modular construction noise isolation device, and the method includes the following steps:

[0009] S1. Determine the installation location of the modular nighttime construction noise isolation device based on the direction of the noise source and the noise-sensitive area;

[0010] S2. Multiple sound insulation modules are placed in the predetermined installation position in sequence, the angle between the sound insulation modules is adjusted, the ear plates at the ends of two adjacent sound insulation modules are aligned vertically, and the connecting bolts are passed through and locked with fastening nuts, so that multiple sound insulation modules are connected in sequence.

[0011] S3. Take each of the uninflated flexible inflatable soundproof walls out of the corresponding base storage box and fix the ground anchor;

[0012] S4. Use an air pump to align with the air valve and inflate each of the flexible inflatable soundproof walls to make them stand up;

[0013] S5. Adjust the verticality of the flexible inflatable sound barrier by adjusting the length of each cable;

[0014] S6. After the noise construction is completed, loosen the cable and use an air pump to extract the gas from the flexible inflatable sound barrier.

[0015] S7. Each of the flexible inflatable soundproof walls is stored back in its corresponding base storage box and the fastening nuts are loosened, so that each of the soundproof modules is separated and independent.

[0016] The positive and progressive effects of this invention are as follows:

[0017] 1. Saves space by using a flexible inflatable structure to reduce volume when not in use, making it easy to store.

[0018] 2. Improved efficiency: The lightweight construction allows for easy installation, disassembly, and transportation. Modular design significantly enhances the flexibility and applicability of the sound insulation device.

[0019] 3. Improved economic efficiency: Compared with the use of higher-cost low-noise construction technologies, construction costs are reduced. Attached Figure Description
