Embodiment Construction

[0032] The following is attached Figure 1-5 The application is described in further detail.

[0033] The embodiment of the present application discloses a foundation reinforcement device for a rotary jet drilling machine with high pull-out strength. refer to figure 1 , 2, including a limiting cylinder 1. The limiting cylinder 1 includes a variable-diameter positioning cavity 2 , an isolation cavity 3 and an end cavity 4 , and the inner diameters of the positioning cavity 2 , the isolation cavity 3 and the end cavity 4 decrease successively. A connection assembly 6 is provided on the positioning cavity 2 , a top connecting plate 401 is provided on the outer wall of the end cavity 4 , and a positioning assembly 5 is provided between the top connecting plate 401 and the positioning cavity 2 . The operator can put the limiting cylinder 1 into the pile hole opened by the rotary grouting drilling rig, and the limiting cylinder 1 can be stably pressed against the inner cavity of...

Abstract

The invention relates to a foundation reinforcing device with high pulling strength for a rotary jet grouting drilling machine. The foundation reinforcing device with high pulling strength for the rotary jet grouting drilling machine comprises a limiting barrel, and a plurality of permeation holes are formed in the outer side wall of the limiting barrel; the limiting barrel comprises a positioningcavity, an isolation cavity and an end cavity, the positioning cavity and the end cavity are located at the two ends of the isolation cavity in the length direction correspondingly, the inner diameter of the positioning cavity is larger than that of the isolation cavity, and the inner diameter of the isolation cavity is larger than that of the end cavity; a plurality of bearing columns are arranged in an inner cavity of the positioning cavity, and a positioning cone is arranged on the outer side wall of the positioning cavity; a top connecting plate is arranged on the outer side wall of the end cavity, and a positioning assembly is arranged between the top connecting plate and the positioning cavity; and a connecting assembly for limiting the position of the positioning cavity is arrangedon the positioning cavity. The foundation reinforcing structure has the effects that the anti-pulling strength of a concrete block body and the limiting barrel in the foundation is improved, and theposition stability and the punning property after the foundation is reinforced are effectively guaranteed.

Description

technical field [0001] The present application relates to the field of foundation reinforcement devices, in particular to a foundation reinforcement device for rotary jet drilling rigs with high pullout strength. Background technique [0002] At present, soft soil often has soft and slippery foundations due to insufficient geological connections. This kind of soft soil is difficult to bear the load brought by infrastructure construction, and it is easy to affect the overall stability of the completed building on the foundation. The foundation reinforcement device is a kind of equipment used to strengthen the foundation. It can improve the degree of compaction and connection strength of the soil by compacting the ground or connecting adjacent fault blocks, thereby improving the overall bearing capacity and stability of the foundation, and It is convenient for the construction unit to construct on the foundation. [0003] The Chinese patent with the publication number CN10430...
