Description

Technical Field

[0001] The utility model relates to the technical field related to foundation pit reinforcement, in particular to a soft soil foundation pit reinforcement structure. Background Art

[0002] At present, due to the characteristics of soft soil foundation such as high natural water content, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor permeability, complex layered distribution of soil layers, and large differences in physical and mechanical properties between layers, it is easy to bring great harm to various types of engineering construction.

[0003] When the foundation pit of the soft soil foundation is in use, due to the instability of the foundation structure, a reinforcement structure is needed to reinforce the inner bottom surface and inner side wall of the foundation. The common structure is composed of a reinforcement plate and anchor rods. The reinforcement plate is installed on the inner wall of the foundation through the anchor rods. It has the advantages of simple structure and convenient construction. However, the following problems are still found during use. Since the soft soil foundation is relatively soft, the conventional anchor rods have poor stabilization effect after being inserted into the foundation, resulting in loosening of the reinforcement plate used to reinforce the foundation, thereby affecting the reinforcement effect of the foundation pit. For this reason, technical personnel in this field have proposed a soft soil foundation pit reinforcement structure to solve the problems raised in the above background. Utility Model Content

[0006] The top end of the rotating shaft is connected with the inner bottom surface of the main anchor bolt, and the top end of the rotating shaft is connected with the outer bottom surface of the main anchor bolt.

[0007] As a further solution of the utility model: the driving rod includes a threaded rod and a cross rod which are connected to each other, and a driven gear is connected to the middle part of the cross rod.

[0008] As a further solution of the utility model: the fixing assembly includes a transverse plate and a bearing sleeve installed in the middle of the transverse plate, the middle of the transverse rod is connected to the bearing sleeve, and the two ends of the transverse plate are respectively connected to the inner walls on both sides of the main anchor rod.

[0009] As a further solution of the utility model: one of the fixing components includes two transverse plates, and the two transverse plates are respectively arranged on both sides of the driven gear.

[0010] As a further solution of the utility model: the inner wall of the auxiliary anchor rod is provided with an internal thread layer, the internal thread layer is threadedly matched with the threaded rod, and a cone tip is installed at one end of the auxiliary anchor rod away from the rotating rod.

[0011] The utility model has the following benefits: the reinforcement structure achieves the fixation of the reinforcement plate by the cooperation of the main anchor rod and the auxiliary anchor rod. After the main anchor rod is inserted into the inner wall of the soft soil foundation pit, the auxiliary anchor rod is driven to extend outward from the rod sleeve through the cooperation of the rotating rod, the driving rod, the fixing assembly, etc., and then the auxiliary anchor rod is inserted into the inner wall of the soft soil foundation pit. The main anchor rod is fixed by the auxiliary anchor rod to prevent the main anchor rod from detaching from and loosening from the inner wall of the soft soil foundation pit, thereby ensuring the fitting effect between the reinforcement plate and the inner wall of the soft soil foundation pit, so that the reinforcement plate can better reinforce the soft soil foundation pit and the use effect is better.
