By inserting the sound insulation board into the sound insulation board slot, the sound insulation board can be fixed by two columns, and there is no gap between the sound insulation board and the column for noise to pass through, which further improves the noise isolation effect.

[0031] Sound insulation board 5, sound insulation board 5 is arranged between adjacent columns 4; the sound insulation board can be: 1. Wooden sound insulation board; wooden sound insulation board generally adopts wood with higher density, such as plywood, MDF board, etc. It has the advantages of light weight and good sound insulation effect. 2. Mineral wool sound insulation board; mineral wool sound insulation board is a sound insulation board made of natural mineral fiber, glue, etc., which has the characteristics of light weight, good sound insulation effect, and relatively low price. 3. Gypsum board; gypsum board is a widely used sound insulation board, which is characterized by relatively low price and easy processing. 4. Steel plate; steel plate is a material with good sound insulation performance and good impact resistance, and is often used in industry, ships, airports, transportation tools and other fields.

[0032] like Figure 6 The base connection device 3 includes a baffle 31, a boss 32 and a steel nail 33;

[0033] In a specific embodiment, the baffle is a rectangular structure, the boss is a square structure, the boss 32 is fixed to one side of the baffle 31 to form an assembly, and a round hole is set in the middle of the assembly; since the assembly needs to bear a large force, its preferred material is stainless steel.

[0034] The base 2 is provided with a base hole 21, the structure of which is compatible with the structure of the boss 32 (such as a square structure), and a base groove 22 is also provided on the lower surface of the base 2, the structure of which is compatible with the structure of the baffle 31; through the above-mentioned structure, the assembly is inserted into the base groove and the base hole from the bottom of the base; further, the base 2 is provided with a first screw hole 23; the baffle 31 is provided with a second screw hole 34; the positions of the first screw hole and the second screw hole correspond; therefore, the assembly can be connected to the base 2 by bolts; the steel nail 33 is used to fix the assembly to the concrete base 1. When fixing the base, the assembly is first fixed to the concrete base with steel nails, and then the base is placed above the assembly, and the base and the assembly are further connected and fixed with bolts. After the foundation pit construction is completed, the sound insulation enclosure needs to be removed. First, remove the screws connecting the assembly and the base, and then the base can be removed. All materials except the assembly and the steel nails can be reused.

[0035] The use process of the noise-reducing soundproof enclosure for deep foundation pit construction of the above embodiment of the utility model is as follows: first, a concrete base is constructed around the foundation pit, the columns are fixedly connected to the base (such as by welding or bolting), and then the base is connected to the concrete base by using a base connection device; while installing the base, the sound insulation board is installed between adjacent columns. After the foundation pit construction is completed, the screws connecting the assembly and the base are first removed, and then the base can be removed. All materials except the assembly and the steel nails can be reused.

[0036] The columns are as follows Figure 3 When the structure shown is set up (the column 4 includes a first clamping plate 42, a second clamping plate and a connecting plate 43, and the connecting plate 43 is vertically connected between the first clamping plate 42 and the second clamping plate; the column 4 includes two sound insulation board slots 41 located opposite to each other.), the positions of the base hole and the sound insulation board are not well laid out, which will cause interference between the installation of the base hole and the sound insulation board. In a preferred embodiment, the base hole 21 is respectively arranged on the outside of the first clamping plate 42 and the second clamping plate. According to the above structure, there is no mutual influence between the connection of the assembly and the base and the installation and removal of the sound insulation board, which is more convenient for construction.
