Embodiment Construction
[0032] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0033] Such as figure 1 As shown, the present invention provides a kind of high-speed railway tunnel construction reinforcement method, comprises the following steps:
[0034] S1: Circle the conduit hole on the tunnel face, and drill the hole with an air drill; after drilling to the designed hole depth, use a blowpipe to blow out the debris to avoid hole collapse; the conduit hole is formed with an air gun or a rock drilling rig Drilling holes, avoiding the swing of the drill pipe and ensuring the straightness of the hole position;
[0035] S2: Insert the catheter into the hole, reserve 20cm to 40cm of slurry stop section at the end of the catheter, 30cm in this embodiment, wrap the hemp silk...

Abstract
The invention provides a high-speed railway tunnel construction reinforcement method and a duct. The construction reinforcement method includes the steps of firstly enclosing a hole position of the duct on a tunnel working surface and drilling a hole through a pneumatic drill; then inserting the duct into the hole position, reserving a slurry stop section of 20cm- 40cm at the tail of the duct, winding the tail of the duct with hemp and wrapping it with an adhesive tape, pushing the duct into the surrounding rock by the impact force of the pneumatic drill; sealing the gap between the duct and ahole position wall with cement-water glass adhesive, and connecting a pipeline; and carrying out a hydrostatic test to detect whether the pipeline and the working surface are leaky, and finally preparing a slurry and conducting the grouting of the duct. The high-speed railway tunnel construction reinforcement method can effectively provide the stability of high-speed railway tunnel construction reinforcement, has high construction efficiency, can reduce the labor intensity of construction workers and has high adjustability; by adopting the high-speed railway tunnel construction equipment provided by the invention, the reinforcement method can be simply and quickly realized and the construction operation efficiency can be improved.
Description
technical field [0001] The invention belongs to the technical field of tunnel construction and equipment, and in particular relates to a high-speed railway tunnel construction reinforcement method and a conduit. Background technique [0002] As the main road of national transportation, the construction stability of high-speed railway has attracted more and more attention from construction personnel; due to the special requirements of high-speed railway on road conditions, more special equipment is needed when building high-speed railway, especially in tunnel construction. ; Existing high-speed railway tunnel construction is difficult and not stable enough, and requires better labor operations for construction personnel. [0003] Based on the above-mentioned technical problems in tunnel construction, there is no relevant solution; therefore, it is urgent to find an effective solution to solve the above-mentioned problems. Contents of the invention [0004] The object of th...
