Problems solved by technology

[0003] At present, the technical problems existing in the excavation construction of underground engineering mainly include the following two points: (1) When supporting, it is necessary to withdraw the roadheader first to leave the space required for the supporting construction, and transport the equipment required for the supporting construction It takes a long time to switch between support and excavation work, which affects the construction efficiency
(2) There is no integrated equipment for tunneling and flexible support that is suitable for flexible support and can almost achieve parallel operations between multiple types of operations

Embodiment 1

[0054] see Figures 1 to 8C As shown, the excavation perfusion support construction equipment provided by the embodiment of the present invention is suitable for excavation and support in underground spaces, the underground spaces include tunnels, roadways, etc., and the equipment includes: machine base 100, rock and soil cutting assembly 200 , the auxiliary supporting component 300 and the concrete pouring component 400 .

[0055] Wherein, the bottom of the base 100 is provided with a traveling mechanism 500, and the base 100 is provided with a hydraulic drive system (which is the prior art, not shown in the figure), and the geotechnical cutting assembly 200 is located in front of the base 100. , for cutting rock and soil, the auxiliary support assembly 300 includes a hydraulic power system and a first mechanical arm 310, a second mechanical arm 320, and a third mechanical arm 330 respectively connected to the hydraulic power system, for individually or cooperatively completi...

Embodiment 2

[0088] see Figure 1 to Figure 13 Shown, the embodiment of the present invention excavation perfusion support construction method, comprises steps:

[0089] S11. Park the excavation grouting support construction equipment in front of the working face to be excavated, and make the rock-soil cutting assembly 200 face the working face to be excavated;

[0090] S12. Start the geotechnical cutting assembly 200 to work. Driven by the hydraulic power system, the geotechnical cutting assembly 200 is stretched from the initial shrinkage state to the excavation work face. Driven by the rotating drive motor, the geotechnical cutting assembly 200 rotates as scheduled Trajectory cutting the rock and soil of the excavation face;

[0091] After cutting a groove with a predetermined outline and a predetermined depth on the excavation face, turn off the rotary drive motor, and shrink the rock-soil cutting assembly 200 to a position close to the front end of the base 100 under the drive of the...

Abstract

The embodiment of the invention discloses excavating, filling and supporting construction equipment and method, and relates to the technical field of underground engineering construction. The equipment comprises a machine base, a rock-soil cutting assembly, an auxiliary supporting assembly and a concrete filling assembly, wherein the rock-soil cutting assembly is positioned in front of the machinebase, and is used for cutting rock-soil; the auxiliary supporting assembly comprises a hydraulic power system as well as a first mechanical arm, a second mechanical arm and a third mechanical arm which are separately connected to the hydraulic power system; the first mechanical arm, the second mechanical arm and the third mechanical arm are separately provided with telescopic shell rings; the first mechanical arm and the second mechanical arm are separately arranged at the two sides of the machine base; the third mechanical arm is arranged on the top of the rock-soil cutting assembly or the top of the machine base; the concrete filling assembly comprises a stirrer and a conveying pump connected to a discharge hole of the stirrer; and the stirrer is arranged on an extending platform at therear end of the machine base. The excavating, filling and supporting construction equipment is suitable for excavating and supporting of underground spaces such as a roadway and a tunnel.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a tunneling perfusion support construction equipment and method. Background technique [0002] During the excavation and construction of underground space, such as the construction of mine roadways and subway tunnels. Usually, a boring machine is used for excavation, and the excavated underground space is supported for each section of excavation, so as to avoid the occurrence of roof caving or surrounding collapse in the underground space. [0003] At present, the technical problems existing in the excavation construction of underground engineering mainly include the following two points: (1) When supporting, it is necessary to withdraw the roadheader first to leave the space required for the supporting construction, and transport the equipment required for the supporting construction It takes a long time to switch between support and excavation work...
