Embodiment 1

[0032] See attached Figure 3-6 As shown, a soft soil foundation reinforcement processing device includes several fastening units 1 arranged in a matrix, all fastening units 1 are inserted in the soft soil layer and two adjacent fastening units 1 are respectively against each other, The interior of the main body of the fastening unit 1 is hollow, and a longitudinal notch 24 is formed on the side.

[0033] The inside of the fastening unit 1 can be filled with gravel and overflow between the circumferential fastening units 1 through the longitudinal slot 24, so that the gap between adjacent fastening units 1 forms a reinforcement space to further strengthen the soft soil layer. hardness. Secondly, when any long-term local force is pressed down, it is easy to cause the problem of subsidence of the soft soil layer. Therefore, two adjacent fastening units 1 are respectively against each other, and cooperate with the gravel placed tightly in the circumferential direction, so that t...

Embodiment 2

[0044] This embodiment improves the abutment member on the sleeve 01 in the fastening unit 1 , and the rest of the structure is consistent with that of the fastening unit 1 in the embodiment. In the first embodiment, due to structural limitations, only two opposite abutting blocks 3 can be provided on the annular sleeve 02 , and the connection with the abutting blocks 3 on the adjacent fastening unit 1 is relatively poor. Therefore, to improve the pusher seat, refer to the attached Figure 7 As shown, wherein the pusher is set as the magnet one 7 fixed on the middle part of the annular sleeve 02 through the connecting block, the abutment block 3 is arranged on the four sides of the annular sleeve 02, and the inner end of the abutment block 3 is provided with a magnet two. 8, wherein magnet one 7 is magnetically identical to magnet two 8. Furthermore, the abutment block 3 can be pushed out by the pusher and come out outward.

Abstract

The invention discloses a soft soil foundation reinforcement treatment device, which comprises a plurality of fastening units arranged in a matrix mode, all the fastening units are inserted into a soft soil layer, every two adjacent fastening units abut against each other, the interior of a main body part of each fastening unit is hollow, a longitudinal notch is formed in the side portion of each fastening unit, and broken stones are fully filled in the fastening units and overflow among the fastening units in the circumferential direction through the longitudinal notches, so that gaps between the adjacent fastening units form reinforcing spaces. According to the method, the fastening unit overall support with the adaptive depth can be formed for soft soil layers with different depths, so that the treatment of the whole foundation can achieve higher strength, meanwhile, the construction cost can be reduced, secondly, the fastening units abut against each other in the vertical direction and the horizontal direction, meanwhile, the fastening units and gaps between the fastening units are filled with broken stones, so that the hardness of the soft soil layer is further enhanced, the bearing capacity of the foundation is increased, and the settlement problem is solved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a soft soil foundation reinforcement treatment device. Background technique [0002] Soft ground is often encountered in construction. In order to carry out building structure and construction on soft ground, it is often necessary to reinforce the soft ground. If the reinforcement of the soft soil foundation is not firm or in place, it will easily cause future settlement and cause a huge safety hazard. [0003] In the existing commonly used construction methods such as dynamic compaction, plum blossoms or square weights are used to array the positions of the compaction points first. After the first dynamic compaction is completed, bulldozers are used to bulldoze and continue to repeat the second or even multiple dynamic compaction operations. However, the foundation soil layer is distributed in layers, and the strength of each layer varies greatly. figure 1 As shown ...
