Description

Technical Field

[0001] The utility model belongs to the technical field of deep foundation pit enclosure, in particular to a deep foundation pit steel enclosure structure. Background Art

[0002] Deep foundation pit steel is a structural support material used in deep foundation pit projects. It is typically composed of high-strength metal profiles such as H-beams, I-beams, and channel steel. During construction, deep foundation pit steel primarily supports the soil surrounding the pit, preventing deformation or collapse, thereby ensuring construction safety.

[0003] In the support scheme of deep foundation pit engineering, deep foundation pit steel is usually coordinated with the retaining structure to ensure the stability of the soil and prevent collapse. At present, there are some retaining structures on the market, such as a deep foundation pit steel retaining structure with the announcement number CN217204125U disclosed on the China Patent Network. This retaining structure can be used for the support of deep foundation pit engineering, but there are some defects and deficiencies that need to be improved: (1) Most of the existing retaining structures are integrated structures. After the project is completed, the relevant components of the retaining structure are difficult to disassemble and recycle, which makes it inconvenient to transport. When the relevant components are damaged, they cannot be replaced separately; (2) Some existing retaining structures lack effective reinforcement measures. When installed on the ground of the deep foundation pit, it is difficult to anchor on the ground, which makes the retaining structure prone to collapse when subjected to the force from the soil and groundwater; (3) Some existing retaining structures lack effective noise reduction measures. When the retaining structure is driven into the ground of the deep foundation pit using equipment such as pile drivers, it is easy to generate loud noise, thereby affecting the living environment of surrounding residents. Therefore, in view of the above problems, the deep foundation pit steel retaining structure provided by the present invention is of great significance. Utility Model Content

[0004] The utility model provides a deep foundation pit steel enclosure structure, which can form a retaining barrier through the mutual cooperation between the enclosure plate and the steel, thereby preventing soil loss and water infiltration in the deep foundation pit. Through modular design, the enclosure plate can be disassembled and recovered from between the steel sections at any time as needed, so as to transport the enclosure structure, and when related parts are damaged, they can also be replaced separately; the spike-shaped bottom end can make it easier for the anchor rod to be inserted into the ground soil of the deep foundation pit; when the anchor rod is inserted into the ground, the barbs of the rod body can be used to increase the grip between the anchor rod and the ground, so that the steel section is firmly anchored to the ground, thereby effectively improving the steel section. The stability of the steel section can be improved by increasing the contact area between the steel section and the ground through the reinforcement block, so as to further improve the stability of the steel section, thereby preventing it from tipping over when subjected to the force from the soil and groundwater; the sound-absorbing cotton in each sound-absorbing groove can effectively absorb the noise generated when the enclosure structure is driven into the deep foundation pit ground by equipment such as a pile driver, so as to play a role in noise reduction; the multiple sound insulation blocks in each sound insulation cavity can block the propagation of noise waves to prevent noise from penetrating the enclosure board, thereby further enhancing the noise reduction effect of the enclosure board, effectively avoiding excessive noise affecting the living environment of surrounding residents, and in summary, solving the problems in the background technology.

[0030] See also Figure 1-7 As shown, a deep foundation pit steel retaining structure of the present invention comprises a plurality of steel sections 1, the steel sections 1 being I-shaped, with slots 2 provided on the top and bottom inner walls of both sides, and a plurality of anchor rods 3 fixedly connected to the bottom of the steel sections 1, which can be inserted into the ground to fix the steel sections 1 to the ground of the deep foundation pit, thereby forming a retaining structure around the deep foundation pit to bear the lateral soil pressure, and a retaining plate 4 is provided between each two adjacent steel sections 1, and the front and rear faces of the retaining plate 4 are provided with There are several sound-absorbing grooves 5, and each sound-absorbing groove 5 is provided with sound-absorbing cotton 6. The sound-absorbing cotton 6 and the sound-absorbing groove 5 are both rectangular, and their length and width are correspondingly equal. The sound-absorbing cotton 6 can be fixed in the sound-absorbing groove 5 by plugging. When the enclosure structure is driven into the ground of the deep foundation pit using equipment such as a pile driver, multiple sound-absorbing cottons 6 can effectively absorb the noise around the construction site to achieve the effect of noise reduction. The front and rear faces of the steel section 1 are fixedly connected with a fixing frame 7, and a reinforcement block 8 is provided in the fixing frame 7.

[0031] Among them, the slot 2 is rectangular, and its slot width is equal to the thickness of the retaining plate 4, and the spacing between the slots 2 at the top and bottom of the steel section 1 is equal to the height of the retaining plate 4. The top and bottom ends of the retaining plate 4 can be inserted and fitted into the corresponding slots 2 respectively. Through the mutual cooperation between the retaining plate 4 and the steel section 1, a retaining barrier can be formed to prevent soil loss and water infiltration in the deep foundation pit. Through modular design, the retaining plate 4 can be removed and recycled from between the steel sections 1 at any time as needed to transport the retaining structure, and when related components are damaged, they can also be replaced individually.

The anti-skid pad 12 is made of elastic material such as rubber and is fixed by glue or the like. The anti-skid pad 12 can play a certain anti-wear role to prevent the bottom of the reinforcement block 8 from directly contacting the ground and causing wear, and the anti-skid pattern on the surface of the anti-skid pad 12 can increase the friction between the reinforcement block 8 and the ground to play an anti-skid role, thereby preventing the steel section 1 from slipping and displacement.

[0036] Among them, a number of sound insulation cavities 13 are opened inside the protective panel 4. The cross-section of the sound insulation cavity 13 is rectangular and is equidistantly linearly distributed along the length direction of the protective panel 4. In addition, a number of sound insulation blocks 14 are fixedly connected to the front and rear inner walls of each sound insulation cavity 13. The sound insulation blocks 14 are triangular and are equidistantly linearly distributed along the height direction of the sound insulation cavity 13. The multiple sound insulation blocks 14 in each sound insulation cavity 13 can block the propagation of noise waves to prevent noise from penetrating the protective panel 4, thereby further enhancing the noise reduction effect of the protective panel 4 and effectively avoiding excessive noise affecting the living environment of surrounding residents.
