Problems solved by technology

The existing grouting is mostly carried out from the surface, or the method of pre-buried grouting pipe is used for grouting, which cannot realize the grouting for the soil in a specific direction, and the grouting effect is poor due to the single grouting point

Embodiment

[0030] Example: Combination Figures 1 to 7 As shown, the rock soil directional grouting apparatus is composed of two parts of the body 1 and the grout body 2, wherein the digging body 1 is mainly used to co-excavate into the grouting region in the generic body with the grouting body 2. The design depth and the grouting body 2 can be protected in the trake body 2, in particular to avoid the grouting body 2 during the tracery.

[0031] like figure 1 and figure 2 As shown, the bottom of the excavating body 1 is pulled out as the shift port of the grout 2, and the inner cavity of the digging body 1 is divided into the stress chamber 3 and the product chamber 4, and the grout 2 is placed in the forming chamber 4, in the device tracing process In the middle, the grout 2 can be displaced as the boss 1. The longitudinal force frame 5 and the lateral force frame 6, the longitudinal force frame 5 and the lateral force frame 6 are mainly used to stabilize the structural frame of the force ca...

Abstract

The invention relates to the technical field of grouting equipment, in particular to a rock-soil body directional grouting device and an application method thereof. The rock-soil body directional grouting device is characterized by comprising a tunneling body and a grouting body, the grouting body is arranged in the tunneling body and can perform overall tunneling along with the tunneling body, and the grouting body can be moved out of the tunneling body; and grout outlet holes are formed in the grouting body, the grout outlet holes are obliquely arranged, and the higher ends of the grout outlet holes correspond to a to-be-grouted area in the rock-soil body. The rock-soil body directional grouting device has the advantages that grouting operation can be carried out on the rock-soil body in the specific direction, the grouting effect is remarkable, and the grouting quality is effectively improved; construction and operation are convenient; and the rock-soil body directional grouting device is simple in structure, clear in function, high in integrity, operability, practicability and creativity and suitable for popularization.

Description

Technical field [0001] The present invention relates to the technical field of grouting equipment, in particular a generous directional grouting apparatus and its application thereof. Background technique [0002] With the growth rate of infrastructure construction, various types of construction projects have gradually accelerated with the re-positioning of application functions. In the construction of infrastructure, there is often a need to demolish both buildings to build, and the surface rocks are loose, the carrying capacity is weak; the new construction of the city has often existed the only building closer; the rail transit station is in the city The traffic is large, and the base pit excavation of the station is also often facing the case where there is only more buildings; the construction of various types of iron-related projects also needs to span, through or near the existing railway line. All of the above-mentioned building conditions need to consider the impact of n...
