A kind of tunnel pre-lining construction equipment and construction method

Abstract

The invention discloses a tunnel initial lining construction device and method. The device comprises a tunneling and perfusion device and an arch machine frame, wherein the tunneling and perfusion device comprises a cutting drill bit, a soil receiving bin, a spiral drill, a spiral soil discharging bin, a power output shaft, a power output shaft bin, a concrete perfusion pipe, a power head, a concrete perfusion amount measurement device, a concrete pressure measurement device, a stratum advanced detection device, a machine case and the like. The construction method comprises the steps of equipment installation, tunneling grooving, concrete perfusion, placement of structural steel or rebars, precast concrete element meshing and the like. The tunnel initial lining construction device and method solve the problems that in an initial lining construction method, adjacent precast concrete elements can not be effectively meshed, a notch is blocked by concrete, shearing resistance of precast concrete elements is poor, and adjacent initial lining structures can not be in effective lap joint.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to tunnel pre-lining construction equipment and a construction method. Background technique [0002] With the rapid development of traffic construction and the improvement of people's living standards, the requirements for safety, quality and progress of tunnel construction are getting higher and higher, and our country's labor resources are becoming increasingly tense, so the mechanized construction of tunnels has become an inevitable trend. [0003] Tunnel pre-lining can ensure the safety of tunnel excavation, and after the tunnel excavation is completed, the lining structure can be used as a part of the tunnel structure, saving materials and avoiding waste of manpower and material resources. The mechanized construction of construction has therefore become the focus of attention in the industry, but this method requires matching equipment. The supporting construction equipment a...

Problems solved by technology

[0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a tunnel pre-lining construction equipment and construction method to achieve rapid positioning of the lining device, flexible walking, and strong site applicability, and to solve the problems existing in the existing pre-lining method. The pre-lined concrete prefabricated parts cannot be effectively occluded, the pre-lined arch cannot be effectively lapped, the tensile strength of the pre-lined arch is low, the concrete pouring cannot monitor the concrete filling status of the tank in time, the structural uniformity of the concrete prefabricated parts cannot be ensured, and the ground conditions ahead of the excavation cannot be guaranteed Questions such as unknown
