Detailed implementation mode

[0028] Please refer to Figures 1-4

[0029] Embodiment 1: A hybrid arrangement type building foundation pit retaining wall, including a left baffle component 1. A right baffle component 2 is arranged on the side of the left baffle component 1. The left baffle component 1 and the right baffle component 2 are in contact with each other through a baffle support component 3 arranged therebetween. Bottom mounting sockets 4 are arranged at the bottoms of both the left baffle component 1 and the right baffle component 2. A side contact plate 5 is arranged on the side of the bottom mounting socket 4.

[0030] The left baffle component 1 includes a first connecting baffle 101. A second connecting baffle 102 is arranged at the top of the first connecting baffle 101. Two first jacks 103 are symmetrically opened on the second connecting baffle 102. Two first connecting screws 104 are symmetrically arranged on both sides of the top end of the first connecting baffle 101. First fixing nuts 105 are sleeved on the top ends of the first connecting screws 104.

[0031] The right baffle component 2 includes a third connecting baffle 201 arranged on the side of the first connecting baffle 101. A fourth connecting baffle 202 is arranged at the top of the third connecting baffle 201. Two second jacks 203 are symmetrically opened on the fourth connecting baffle 202. Two second connecting screws 204 are symmetrically arranged at the top end of the third connecting baffle 201. Second fixing nuts 205 are sleeved on the top ends of the second connecting screws 204.

[0032] The baffle support component 3 includes side rotation grooves 301 symmetrically opened on both sides of the side of the fourth connecting baffle 202. Support connecting rods 302 are arranged on the sides of the side rotation grooves 301. One end of the support connecting rod 302 is connected with a rotation connecting block 303. A rotation insertion shaft 304 is inserted in the middle of the rotation connecting block 303. The end of the rotation insertion shaft 304 is rotationally connected with the inner wall of the side rotation groove 301. The other end of the support connecting rod 302 is rotatably provided with an adjustment screw cylinder 305. An adjustment screw 306 is threadedly inserted into the end of the adjustment screw cylinder 305.

[0033] A fixing jack 307 is opened at the end of the adjustment screw 306. Two side wall contact grooves 308 are symmetrically opened on the side of the second connecting baffle 102. Two contact jacks 309 are symmetrically opened at the top end of the second connecting baffle 102. The bottom of the contact jack 309 is communicated with the side wall contact groove 308. Contact insertion rods 310 are inserted into the contact jacks 309. A connecting spring 311 is sleeved on the contact insertion rod 310. One end of the connecting spring 311 is connected with the rod body of the contact insertion rod 310. The other end of the connecting spring 311 is connected with the top of the second connecting baffle 102.

[0034] Example 2: The difference between this example and Example 1 is that the side surface of the side contact plate 5 is inclined.

[0035] Reduce the occupation of the bottom space of the foundation pit by the side contact plate 5, facilitating the movement of the operating equipment at the bottom of the foundation pit.

[0036] Example 3: The difference between this example and Example 1 is that a slot is provided at the top end of the bottom mounting socket 4, and the bottom ends of the first connecting baffle 101 and the third connecting baffle 201 are both inserted into the slot.

[0037] Enable the first connecting baffle 101 and the third connecting baffle 201 to be more conveniently inserted into the bottom mounting socket 4.

[0038] Example 4: The difference between this example and Example 1 is that the bottom end of the connecting spring 311 extends into the side wall contact groove 308 and penetrates the fixing jack 307.

[0039] So that the contact plug 310 is inserted into the fixing jack 307 under the elastic contact of the connecting spring 311, and the end of the adjusting screw 306 is limited and contacted.

[0040] In this embodiment, during the actual implementation of the existing retaining wall for building foundation pits, since the side of the baffle used for the retaining wall needs to be resisted by support columns, and the bottom end of the side support column directly resists the bottom of the foundation pit, it will occupy a relatively large space at the bottom of the foundation pit, thus easily affecting various operations of the construction workers at the bottom of the foundation pit.

[0041] In summary, during specific implementation, through the provided left baffle assembly 1 and right baffle assembly 2, the first connecting baffle 101 and the second connecting baffle 102 in the left baffle assembly 1 can be connected by inserting the first connecting screw 104 into the first jack 103, thereby resisting the inner wall of the building foundation pit. The top of the third connecting baffle 201 is provided with a fourth connecting baffle 202, and the connection between the fourth connecting baffle 202 and the third connecting baffle 201 is achieved by inserting the second connecting screw 204 into the second jack 203. By sleeving the first fixing nut 105 on the top end of the first connecting screw 104 and sleeving the second fixing nut 205 on the top end of the second connecting screw 204, the first connecting baffle 101 and the second connecting baffle 102 can be assembled and connected to be placed on the inner wall of the tunnel, and the third connecting baffle 201 and the fourth connecting baffle 202 can be assembled and connected to be placed on the inner wall of the other side of the tunnel.

[0042] Furthermore, through the baffle support assembly 3 arranged between the second connecting baffle 102 and the fourth connecting baffle 202, by rotating the support connecting rod 302, the fixed jack 307 connected to the end of the support connecting rod 302 can be moved into the side wall abutment groove 308. And since the end of the adjusting screw 306 is threadedly inserted into the adjusting barrel 305, the length of the support rod formed by the support connecting rod 302 and the adjusting screw 306 can be adjusted. Thus, after the distance between the second connecting baffle 102 and the fourth connecting baffle 202 is adjusted, the user can also insert the end of the adjusting screw 306 into the side wall abutment groove 308 by rotating the adjusting screw 306.

[0043] Furthermore, under the pulling force of the return spring 311 of the abutting plug rod 310 arranged at the top of the second connecting baffle 102, the bottom end of the abutting plug rod 310 is inserted into the fixed jack 307. Thus, the left baffle assembly 1 and the right baffle assembly 2 can firmly abut and fix the inner wall of the building foundation pit under the support of the baffle support assembly 3, effectively preventing the soil on the inner wall of the foundation pit from falling off. And this device will not occupy the bottom space of the foundation pit, so that a wider working space can be reserved, facilitating the operation of construction workers on the bottom of the foundation pit.
