Description

Tunnel Second Lining spraying health promotion chassis

Technical field

This utility model relates to constructing tunnel engineering field, is specifically related to a kind of Tunnel Second Lining spraying health promotion chassis, for tunnel Spray maintenance after road secondary lining concreting completes, to secondary lining concrete.

Background technology

Along with developing rapidly of highway, tunnel structure thing, in addition to sedimentation and deformation requirement to be met, be also satisfied that to bear driving logical Out-of-date wind pressure, drive a vehicle by time, tunnel structure is stable, two lining surfaces does not fall block, it is impossible to jeopardize traffic safety.This will Ask tunnel double-lining concrete should have enough intensity, meet life requirement again.Tunnel concrete strength durable influence factor, except former Outside material, match ratio etc., an also important factor in order concrete curing.After concrete cast, such as hot climate, air Being dried, carry out maintenance not in time or maintenance is not in place, in concrete, moisture can evaporate too fast, forms dehydrating phenomena, can make shape The cement granules becoming gelinite can not abundant aquation, it is impossible to be converted into stable crystallization, lacks enough cohesive forces, thus can be Concrete surface occurs that lamellar or powdery come off.Additionally, when concrete not yet possesses enough intensity, the evaporation that moisture is too early Also can produce bigger contraction distortion, cup shake occurs, affect durability and the globality of concrete.

But in current tunnel construction, commonly used artificial watering maintenance, the most bothersome arduously, work high above the ground also has certain Risk, and maintenance is not in place, causes two lining concrete surface color whiting, and intensity is not enough, and durability is greatly affected.

Summary of the invention

The purpose of this utility model is the weak point for Tunnel Second Lining health preserving work, it is provided that a kind of special tunnel two Secondary lining cutting spraying health promotion chassis.

The technical solution of the utility model is as follows:

A kind of Tunnel Second Lining spraying health promotion chassis, including gate-type frame, described gate-type frame includes that two are horizontally disposed with and the most flat The lower longeron that row is arranged, every lower longeron welds at least 2 vertical supportings vertical with lower longeron, gate-type frame both sides vertical Support upper end to be connected by the upper longeron parallel with lower longeron respectively, by least two horizontal strokes vertical with upper longeron between longeron on two Beam connects, and every lower longeron two ends set road wheel, it is characterised in that: a water-supply-pipe, described water-supply-pipe are set on described gate-type frame Around gate-type frame both sides and top, one end of water-supply-pipe connects a rubber hose, and the other end is closed；Water-supply-pipe is provided with multiple Sparge pipe, the end of each sparge pipe is provided with shower nozzle.

This utility model integrates depositing dust in spraying health promotion, two lining concrete modifications, two lining cavity slip casting, holes.Use this reality With novel, Tunnel Second Lining concrete is sprayed maintenance, it is ensured that Tunnel Second Lining concrete strength and durability, concrete outward appearance Quality is compared and is significantly improved before, compares traditional health preserving of manually sprinkling water, time and labour saving, achieves good economic benefit.

This utility model also can determine sprinkle water and spray interval time according to execution conditions, sprays and form water curtain after two lining chassis, Play depositing dust, dust-separation in hole, improve job execution environment in hole.

This utility model additionally provides work platforms, and workmen can carry out polishing by work platforms to tunnel-liner face and modify, Improve two lining presentation qualities.

Detailed description of the invention

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Tunnel Second Lining spraying health promotion chassis that this utility model provides, including door Formula frame, described gate-type frame includes two lower longerons 1 be arrangeding in parallel, every lower longeron 1 arranges at least 2 vertical supportings 2, Vertical supporting 2 upper end of gate-type frame the same side is connected by upper longeron 3, vertical with upper longeron by least two between longeron on two Crossbeam 4 connect, every lower longeron 1 two ends set road wheel 5；A water-supply-pipe 6, described water delivery is also set up on described gate-type frame Pipe 6 is around gate-type frame both sides and top, and one end of water-supply-pipe 6 connects a rubber hose 7, and the other end is closed；On water-supply-pipe Being provided with multiple sparge pipe 8, the end of each sparge pipe 8 is provided with shower nozzle 9.

When this utility model is embodied as, described water-supply-pipe 6 uses steel pipe manufacturing, is welded to connect with gate-type frame.Will be located in gate-type Sparge pipe 8 spacing on the water-supply-pipe of top of the trellis is set to 50cm, and the height of each sparge pipe 8 reduces to both sides successively from middle, It is easy to according to tunnel contour line two lining concrete comprehensive spray maintenances.

This utility model, in addition to having spray care action, may also provide workmen and secondary lining carries out the work that polishing is modified Platform.Detailed description of the invention is, sets the work platforms of at least two-layer differing heights, every layer of work respectively in described gate-type frame both sides Platform includes the horizontal cross bar 10 that many one end are welded with described vertical supporting, welds between every horizontal cross bar 10 and vertical supporting 2 It is connected to hound 11, is connected by many horizontal vertical poles 12 between each horizontal cross bar.Flat surface plate is laid on horizontal vertical pole 12.Position The width of the work platforms in lower section is more than the width of work platforms above it, it is simple to workmen operates.

When being embodied as, also guard rail 13 can be set in the periphery of described work platforms, provide safety guarantee for workmen.

As a kind of detailed description of the invention of the present utility model, the crossbeam of gate-type frame, upper longeron, lower longeron and vertical supporting can be adopted Welding with 22b I-steel, described water-supply-pipe uses φ 48 steel pipe manufacturing, is welded to connect with gate-type frame.Water-supply-pipe is just to two lining tables Face position welding sparge pipe, the end sprayer of sparge pipe is away from two lining profile 0.3-0.5m.

Tunnel high-pressure water pipe sets one for Water gate valve, supply concrete curing water in two lining concrete curing certain distance 50m.Water delivery Pipe is laid the termination of water under high pressure tube side and is connected rubber hose in tunnel, for being connected for Water gate valve with high-pressure water pipe, water-supply-pipe another Termination is closed.

As shown in Figure 4, after tunnel double-lining concrete 14 has poured form removal, this utility model Tunnel Second Lining spray is supported Raw chassis moves to firm form removal two section of lining, connects the high-pressure water pipe in tunnel by the rubber hose 7 of water-supply-pipe 6 one end.Open and adjust Whole high-pressure water pipe switch gate valve, makes the shower nozzle 9 of sparge pipe 8 serve as a contrast concrete 14 water smokes to two, at same fixed position during water spray Continuing water spraying time is 1min.

Health preserving chassis uses artificial promotion, controls at the uniform velocity to move forward time mobile, and translational speed is 6m/min.

The maintenance time limit is generally 14d, sprays water smoke maintenance 2h interval time, it is ensured that concrete is in moisture state.

This utility model, in addition to providing two lining concrete curing functions, also can determine when sprinkle water and spray is spaced according to execution conditions Between, spray after two lining chassis and form water curtain, play depositing dust, dust-separation in hole, improve job execution environment in hole.

Workmen also can carry out polishing modification, two lining cavity notes on the work platforms that this utility model provides to tunnel-liner face The operations such as slurry, to improve two lining presentation qualities.
