Problems solved by technology

[0002] Goaf piling technology has always been a technical problem that plagues people. If the project is directly built on the goaf, it will inevitably lead to safety problems in the goaf, and the settlement of the goaf collapse is often accompanied by many problems. After mining The original stress field of the strata is destroyed, resulting in cracks, fissures, and gaps formed by the caving of the overlying stratum, which brings great difficulty to the subsequent engineering construction.
If it is completely filled with concrete, a lot of materials will be wasted and the construction period will be delayed, so a reinforcement device that can quickly fill the gaps, cracks and pores in the formation and save materials is needed

Embodiment Construction

[0025] The following is attached Figure 1-6 The specific implementation manners of the present invention are further described in detail.

[0026] When this embodiment is in use, the required materials are first prepared in the pressure feeder, and the various components in the pressure feeder work together to store the required materials in the stocker, and the stocker When various materials are used, the set ratio of materials is transported to the mixing device 12, and the various materials are uniformly mixed in the mixing device 12. The mixed materials need to meet the following conditions and can be carried out in the underground space. Solidification, after solidification, the required strength can be achieved, and solidification can be carried out in an oxygen-free environment, and then the mixed materials are placed in the mixing device 12 until used, and at the same time, the carrier vehicle 1 is driven to the designated place, and the upper end of the carrier vehic...

Abstract

The invention provides a goaf deep pile forming device. The goaf deep pile forming device can reinforce and reinforce a goaf stratum and meet the requirements for bearing capacity, strength and stability of a goaf engineering construction stratum. The pile forming device can shorten the construction period and reduce the manufacturing cost and has little influence on the surface environment. According to the technical scheme, the goaf deep pile forming device comprises a bearing vehicle and is characterized in that a vertically-arranged guide rail is fixedly connected to the bearing vehicle, a drilling rod is slidably connected to the guide rail and is of a hollow structure, the upper end of the drilling rod is connected with one end of a feeding pipe, the other end of the feeding pipe is connected with a pressure feeder, the lower end of the drilling rod is detachably connected with a drilling head, symmetrically-arranged discharging holes are formed in the front side face and the rear side face of the drilling head correspondingly, and drilling teeth are fixedly connected to the lower end of the drilling head.

Description

technical field [0001] The invention relates to a stabilizing device for a goaf, in particular to a deep pile forming device for a goaf. Background technique [0002] Goaf piling technology has always been a technical problem that plagues people. If the project is directly built on the goaf, it will inevitably lead to safety problems in the goaf, and the settlement of the goaf collapse is often accompanied by many problems. After mining The original stress field of the strata is destroyed, resulting in cracks, fissures, and gaps formed by the caving of the overlying stratum, which brings great difficulty to the subsequent engineering construction. If it is completely filled with concrete, a large amount of materials will be wasted and the construction period will be delayed. Therefore, a reinforcement device that can quickly fill the gaps, cracks and pores in the formation and save materials is needed. In the process of filling, it is also necessary to adjust the correspond...
