DETAILED DESCRIPTION

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-5As shown, a road soft soil foundation reinforcement structure includes several groups of support components, each of which includes two blocking parts and a support part. The blocking part includes a bottom plate 2, a mounting seat 3 is arranged at the center of the outer surface of one side of the bottom plate 2, a sleeve 4 is arranged on the mounting seat 3, and only one end of the sleeve 4 is open. The outer surface of the sleeve 4 is symmetrically provided with fixed shafts 5, and the fixed shafts 5 are rotatably connected to the mounting seat 3. A worm gear 6 is arranged on one of the fixed shafts 5, and a worm 7 matched with the worm gear 6 is arranged on the mounting seat 3. The support part includes a first connecting rod 8 and a second connecting rod. Connecting rod 9, one end of the first connecting rod 8 can be placed in the sleeve 4, and the other end of the first connecting rod 8 is symmetrically provided with a fixing column 10, and the outer surface of the fixing column 10 is provided with an external thread, one end of the second connecting rod 9 can be placed in the sleeve 4, and the other end of the second connecting rod 9 is provided with a slot, one end of the first connecting rod 8 is located inside the slot and is slidably connected to the second connecting rod 9, and the outer surface of the second connecting rod 9 is symmetrically provided with a through groove 11 that penetrates the slot, the fixing column 10 is located inside the through groove 11, and also includes a nut 12 threadedly connected to the fixing column 10.

[0019] When the base plate 2 is in use, the two base plates 2 need to be tilted and placed on the side of the soft soil layer 1 respectively, and then the worm screw 7 is rotated. Through the cooperation of the worm screw 7 and the worm wheel 6, the fixed shaft 5 is driven to rotate, and then the sleeve 4 is driven to rotate. When the sleeve 4 rotates to be parallel to the plane at the bottom of the foundation pit, the worm screw 7 is stopped. At this time, the position of the sleeve 4 is determined, and then one end of the first connecting rod 8 is extended into one of the sleeves 4, and then the second connecting rod 9 is moved, and one end of the second connecting rod 9 is extended into the other sleeve 4. When the first connecting rod 8 and the second connecting rod 9 are respectively abutted against the bottom ends of the two sleeves 4, the first connecting rod 8 and the second connecting rod 9 are fixed through the threaded connection of the nut 12 and the fixing column 10, so that the first connecting rod 8 and the second connecting rod 9 remain in a relatively stable state, and the two base plates 2 are supported to the two sides of the soft soil layer 1 through the first connecting rod 8 and the second connecting rod 9.

[0020] Through the self-locking effect of the worm wheel 6 and the worm 7, after the sleeve 4 is adjusted, the worm wheel 6 cannot be effectively rotated without rotating the worm 7, ensuring that the sleeve 4 can always maintain the adjusted position.

[0021] When facing different slopes on both sides of the soft soil layer 1, the position of the sleeve 4 can be quickly adjusted so that the sleeve 4 can always remain parallel to the ground of the foundation pit, making it easy to insert the first connecting rod 8 and the second connecting rod 9 into the sleeve 4 on the bottom plates 2 on both sides respectively, and the first connecting rod 8 and the second connecting rod 9 can also remain parallel to the ground of the foundation pit, thereby making the bottom plate 2 more stable.

[0022] Furthermore, the four corners of the base plate 2 are provided with stepped grooves passing through the base plate 2, and also include an anti-slip rod 13, the anti-slip rod 13 includes a rod body and a head. After the rod body is extended into the soft soil layer 1, the head of the anti-slip rod 13 abuts against the stepped groove. After the base plate 2 is tilted and placed on both sides of the soft soil layer 1, one end of the anti-slip rod 13 is passed through the stepped groove and inserted into the soft soil layer 1, thereby effectively preventing the base plate 2 from moving and improving the supporting and protective effect of the base plate 2 on the soft soil layer 1.

[0023] Furthermore, an extension rod 14 is provided at the head of the anti-slip rod 13 , and an end plate 15 is provided at the end of the extension rod 14 . By controlling the end plate 15 and the extension rod 14 , the anti-slip rod 13 can be easily pulled out of the soft soil layer 1 .

[0024] Furthermore, an annular rubber pad 16 is sleeved on the fixing column 10 and the rubber pad 16 is located between the second connecting rod 9 and the nut 12 to increase the friction between the nut 12 and the second connecting rod 9 and improve the matching stability of the first connecting rod 8 and the second connecting rod 9.

[0025] Furthermore, an anti-skid groove 17 is provided on the outer surface of the bottom plate 2 on the side in contact with the soft soil layer 1. The anti-skid groove 17 is a continuous V-shaped groove. The anti-skid groove 17 can increase the friction between the bottom plate 2 and the soft soil layer 1, thereby further limiting the movement ability of the bottom plate 2 on the soft soil layer 1.

[0026] The device can support both sides of the soft soil layer 1, thereby preventing the soft soil layer 1 on both sides of the foundation pit from collapsing and reducing safety hazards. At the same time, it can also quickly adjust the angle of the sleeve 4, so that the first connecting rod 8 and the second connecting rod 9 can quickly cooperate with the sleeves 4 on the two bottom plates 2, thereby improving the assembly efficiency of the sleeve 4 and the first connecting rod 8 and the second connecting rod 9, and the use effect is good.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
