Abstract

The invention discloses an intelligent installing method of an underground engineering standardized assembled confined concrete arching frame. The method comprises the steps of conducting concrete pre-pouring on a single-joint arching frame outside a tunnel, precisely welding an assembled joint with the arching frame for arching frame trial assembling, folding to form an assembled arching frame, using arching installing equipment to erect the arching frame after hoisting the arching frame to a heading face of the tunnel, making the arching frame connected with a longitudinal locating device, using a laser locating instrument and an arching frame lifting device to precisely locate the whole truss of the arching frame, using a laser distance measuring device to conduct fracture surface rechecking, drilling feet-lock bolts, and then executing other work procedures. By means of the intelligent installing method of the underground engineering standardized assembled confined concrete archingframe, a confined concrete arching frame pre-pouring key technology is implemented, suspension and one-time erection of the whole truss of the arching frame are achieved, the construction efficiencyis improved, and the construction safety is guaranteed.

Description

technical field [0001] The invention relates to an intelligent installation method for a standardized assembled constrained concrete arch suitable for underground engineering. Background technique [0002] With the rapid development of tunnel traffic construction, the scale of construction has gradually increased, and the number of important and difficult projects in tunnel construction has increased under complex geological conditions such as shallow burial, bias pressure, high stress, and fault fracture zones. Due to insufficient strength and rigidity or untimely support, traditional support forms such as anchor net spraying, section steel arch frame, and grid steel frame frequently cause safety accidents such as vault collapse, large deformation, and support component breakage. Confined concrete arches, as a new form of support, have high strength and high rigidity bearing characteristics, have been widely used in mine roadways, and have been gradually popularized and app...
