Problems solved by technology

[0005] The above-mentioned patents have the same technical field as the present application, and solve the same technical problems. However, during the construction process, the water spray device used to spray water on the lining structure will cause the road inside the tunnel construction site to be muddy. At the same time, the device Drive forward for the trolley, which will occupy the space under the tunnel and make other construction impossible

Embodiment 1

[0027] As shown in the figure, the tunnel concrete maintenance device includes connectors 4 and arches 13. The connectors 4 are uniformly installed on the tunnel lining concrete 1. The connectors 4 are in two rows, and the two rows of connectors 4 are arranged along the The center line is symmetrically arranged, and a slot 12 is installed below it through a fastener 11. The I-beam 10 is installed in the slot 12. The pulley is installed in the slot 12 and is stuck in the I-beam 10. The tunnel lining concrete 1 Reinforcement ribs 2 are also poured inside.

[0028] The arch frame 13 is divided into an upper arch frame 9 and a lower arch frame 8, threaded rods 15 pass through the upper arch frame 9 and the lower arch frame 8, and the top is provided with a threaded structure 14 screwed into the I-beam 10 to secure the arch frame 13. Fixed below the I-beam 10, the upper arch 9 is provided with an arc-shaped groove, the steam pipe 6 is installed in the arc-shaped groove, and the ste...

Abstract

A tunnel concrete curing device is characterized by comprising connecting parts and a lagging jack, the two rows of connecting parts are evenly distributed on tunnel lining concrete, necks are installed under the connecting parts through fastening pieces, I-steel is installed in the necks, and pulleys are arranged in the necks and clamped in the I-steel. Compared with the prior art, the device has the advantages that structure is simple, the device is obtained through welding of round steel, manufacturing speed is high, and manufacturing cost is low; operation is convenient and can be conducted simply by fixing the device and conveying water vapor at predetermined time; construction under a tunnel is not affected, the whole device is located above the tunnel and moves above the tunnel, and therefore construction and travel under the tunnel are normal.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a tunnel concrete maintenance device and a construction method thereof. Background technique [0002] The structure of the tunnel includes two parts, the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel door. The auxiliary equipment includes car avoidance tunnels, fire protection facilities, emergency communication and waterproof and drainage facilities. The long tunnel also has special ventilation and lighting equipment. [0003] After the concrete is poured, if the climate is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be transformed into stable crystals. Lack of sufficient cohesion, re...
