Problems solved by technology
[0002] The traditional tunnel inverted arch excavation construction is mainly excavation and blasting by excavators. The inverted arch trestle provides vehicle access, and the concrete tank truck transports concrete. Enough concrete solidification time; the excavation time of the inverted arch is slow, the construction time of the inverted arch is long, the construction speed is slow, and the cost is high

The invention belongs to the technical field of tunnel inverted arch construction and provides tunnel inverted arch rapid excavation construction equipment and a construction method thereof. The construction method comprise the steps that a tunnel inverted arch foundation is subjected to excavation and residue removal; a prefabricated inverted arch model is hoisted into an inverted arch groove where residues are removed, and the prefabricated inverted arch model is installed and positioned. The construction equipment comprises a headstock part, a tailstock part, a mounting bracket part and a driving passage, wherein the front end of the headstock part is provided with a milling and excavating device; a plurality of first oil cylinders are arranged at the rear end of the tailstock part, andthe mounting bracket part is connected with the tailstock part; the front end of the driving passage is connected with the upper portion of the non-excavated portion of the front end of the invertedarch groove, and the rear end of the driving passage is connected with the upper portion of the prefabricated inverted arch model which is installed; the upper end of the headstock part and the upperend of the tailstock part are both provided with a left support and a right support for supporting the driving passage, and both the headstock part and the tailstock part move forwards at the bottom of the inverted arch groove. According to the method, construction can be conducted while excavation is carried out during inverted arch construction, the efficiency is improved, and the cost is reduced.
Description
Technical field [0001] The invention belongs to the technical field of tunnel invert construction, and specifically relates to a construction equipment for rapid excavation of a tunnel invert and a construction method thereof. Background technique [0002] The traditional tunnel invert excavation construction mainly involves excavator excavation and blasting. The inverted arch trestle provides vehicle access, and the concrete tanker transports the concrete. The constructors construct under the inverted arch trestle and are poured in layers. Each layer must be left for construction. Enough concrete solidification time; invert arch excavation time is slow, invert arch pouring construction time is long, construction speed is slow, and cost is high. Summary of the invention [0003] The purpose of the present invention is to provide a tunnel invert rapid excavation construction equipment and a construction method for the above-mentioned problems and deficiencies, which can ensure that...
