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 concrete curing 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 tunnel center Line symmetrical arrangement, below which is installed a card slot 12 through the fastener 11, the I-beam 10 is installed in the card slot 12, and the pulley is installed in the card slot 12 to be stuck in the I-beam 10, and the tunnel lining concrete 1 There are also reinforcing ribs 2 poured.

[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, an...

Abstract

A concrete curing device is characterized by comprising connecting pieces and a lagging jack, the connecting pieces are evenly distributed on tunnel lining concrete and are arranged in two columns, clamping grooves are formed below the connecting pieces through fasteners, joist steel is installed in the clamping grooves, and pulleys are arranged in the clamping grooves and clamped in the joist steel. Compared with the prior art, the concrete curing device has the advantages that the structure is simple, the concrete curing device is formed by welding round steel, the manufacturing speed is high, and the manufacturing cost is low; operation is convenient, and it is only needed to perform fixing and convey water vapor according to the set time; underground construction of an underground tunnel is not affected, the whole device is arranged above the tunnel and can move at the upper portion, and accordingly the underground construction and passing abnormality are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a 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, resulting...
