Description

Technical Field

[0001] The invention belongs to the field of tunnel construction equipment, and in particular relates to a non-explosive construction device and method for a deep-buried water ditch in the center of a tunnel. Background Art

[0002] At present, the blasting method is mostly used at the construction site of the central deep-buried ditch of the tunnel, that is, a pneumatic rock drill, a down-the-hole drill or a three-arm rock drilling rig is used to drill vertical pre-crack holes or longitudinal horizontal holes in the central ditch, and the blasting method is used to complete the excavation of the central deep-buried ditch in stages. The following problems often occur during construction:

[0003] (1) The phenomenon of over-excavation and under-excavation in blasting excavation is serious. Since the overall cross-section of the central ditch is mostly inverted trapezoidal, it is affected by the surrounding rock conditions, drilling equipment, drilling quality, and blasting parameter design during blasting excavation construction. The phenomenon of over-excavation and under-excavation often occurs after blasting of the central deep buried ditch, resulting in serious waste of concrete backfill.

[0004] (2) The ditch excavation process has great interference and low construction efficiency. The central deep-buried ditch is arranged at the bottom of the invert. Due to the narrow space of the excavation working face and the cross-operation with the heading face process, the central ditch construction often has low excavation efficiency, which restricts the overall construction progress of the tunnel.

[0005] (3) The construction process is complicated and the construction quality control is difficult. After the central deep buried ditch is blasted and excavated, the subsequent construction involves multiple processes such as slag removal, wall spraying concrete, water pipe base installation, water pipe installation, and gravel filter layer backfilling, and the construction quality is not easy to control.

[0006] (4) Impact on safe tunnel construction. In areas with poor surrounding rock, if the excavation of the central ditch takes a long time, the initial support of the invert will not be closed in time, increasing the risk of safe tunnel construction.

[0007] In view of the above problems, it is urgently necessary for technical personnel in this field to propose a non-blasting method for constructing a tunnel center ditch. Summary of the invention

[0008] In view of this, the present invention provides a non-explosive construction device and method for a deep-buried water ditch in the center of a tunnel, which are used to solve the above-mentioned problems.

[0009] In order to achieve the above object, the present invention adopts the following technical solution:
