Abstract

This application relates to a foundation reinforcement device for rotary grouting drilling rigs with high pullout strength, which includes a limiting cylinder, the outer wall of the limiting cylinder is provided with a number of penetration holes; the limiting cylinder includes a positioning cavity, The isolation cavity and the end cavity, the positioning cavity and the end cavity are respectively located at the two ends of the length direction of the isolation cavity, the inner diameter of the positioning cavity is larger than the inner diameter of the isolation cavity, and the isolation cavity The inner diameter of the body is larger than the inner diameter of the end cavity; the inner cavity of the positioning cavity is provided with a number of receiving columns, and the outer wall of the positioning cavity is provided with a positioning cone; the outer wall of the end cavity is provided with a butt joint A positioning assembly is provided between the top connecting plate and the positioning cavity; a connecting assembly for defining the position of the positioning cavity is provided on the positioning cavity. The application has the effect of improving the pull-out strength of the concrete block and the limiting cylinder in the foundation, and effectively ensuring the positional stability and compaction of the foundation after reinforcement.

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...
