Abstract
The invention relates to a device for installing a contact net in a tunnel in electrified railway engineering, which is characterized in that the back of a channel flow and the bottom of an anchor rod are connected in a welding mode, galvanized and fixed by poring concrete; and the head of a T-shaped bolt is put into the channel flow to ensure that the T-shaped bolt can slide freely in use. The processing of the channel flow comprises the following steps: hot-rolling and molding roughcast and remaining machining allowance; and lubricating cold-rolling and molding after acid washing, alkali wash and water wash, wherein the blooming temperature of rolling is 1050 DEG C, and the finish rolling temperature is 75 DEG C. The device effectively overcomes the defects in the prior art and has pre-embedded installation and no need of post-drilling, is level with concrete after embedded into the concrete, does not occupy space, is easy to install and adjust, reduces the installation time of a contact net structure in a tunnel, reduces the construction cost, and the like.
Description
Technical field
What the present invention relates to is a kind of installing contact net equipment in the electrified railway engineering tunnel that is used for, and belongs to tunnel installation accessories technical field.
Background technology
At tunnel internal fixation structure stand, traditional in the past way is planted crab-bolt after being, way is: bolt, filling concrete are planted in the tunnel lining punching; The tunnel lining punching is filled the chemical glue compound and is planted crab-bolt.No matter be which kind of plants the crab-bolt way after, all will punch, all can cause certain destruction tunnel lining in tunnel lining.And weighting material and the firm degree of concrete bonding are much smaller than the monolithic concrete structure.After plant that crab-bolt is stressed to be concentrated, cause the contact structures subsidiary load bigger to the tunnel lining influence, the fire retardancy of chemical anchor bolts is relatively poor, and construction is inconvenient, cost is high.The fastness of planting plain bolt behind the back plant crab-bolt ratio is better, and is more with chemical anchor bolts in the tunnel usually.Since after to plant the crab-bolt defective more, plant the way of crab-bolt abroad after generally adopting pre-buried conduit to replace, cost is higher.
Summary of the invention
The present invention proposes a kind of installing contact net equipment in the tunnel that is applicable in the electrified railway engineering, be intended to overcome the above-mentioned defective of existing in prior technology, has pre-buried installation, need not back boring, imbed in the cement concrete and flush, do not take up room, install, adjust easy with cement concrete, can reduce the required time of contact system structure installation in the tunnel effectively, reduce characteristics such as construction costs effectively.
Technical solution of the present invention: it is zinc-plated to it is characterized in that the conduit back side and anchor pole bottom is connected by welding process, irrigates fixingly with concrete casting, and the head of T type bolt is put into the inside of conduit, and assurance T type bolt can be free to slide in use.
Advantage of the present invention: adopt pre-buried grooved slideway scheme, can in the design of tunnel lining and work progress, finish synchronously.Conduit back anchor pole is built framework of steel reinforcement with tunnel and is connected closely, guarantees the stressed safety of channel system, makes the stressed demand of contact system can receive sufficient consideration and realization; With after plant crab-bolt and compare, hang and stressedly more disperse, contact system structure subsidiary load is littler to the influence of tunnel lining; Pre-buried installation need not back boring, avoids tunnel lining is damaged; Compare with chemical anchor bolts, can improve the safety on contact system basis in the tunnel; Imbed in the cement concrete and flush, do not take up room, not influenced by construction in later period with cement concrete; Conduit has briar tooth, and fitting like a glove with the T type bolt that has teeth forms firm mechanical snap, and effectively opposing is impacted and oscillatory load, prevents loosening slippage; In order to prevent that cement wash from infiltrating in the channel-section steel, the foam-filled thing of the built-in T type of pre-buried conduit, and weighting material extrusion packing thing when exceeding conduit 1.5mm and guaranteeing that template fixedly prevent that better cement wash from mixing in the conduit mouth; Install, adjust easy, can reduce the required time of the contact system structure installation tunnel in effectively; Reduce construction costs effectively.
Description of drawings
Fig. 1 is the conduit section drawing.
Fig. 2 is the anchor structure scheme drawing.
Fig. 3 is conduit and anchor pole and other mating parts connection diagram.
Among the figure 1 is the age of a draught animal of conduit; The 2nd, the conduit side; The 3rd, the conduit back side; The 4th, the anchor pole top; The 5th, the anchor pole bottom; The 6th, the anchor pole mobile jib.
The specific embodiment
Contrast accompanying drawing 2, its structure is that two anchor pole tops 4 are two identical faces, and the distance h 7 on this two sides is 125mm, and width h8 is 30mm, and thickness h 9 is 7mm; The thickness h 10 of anchor pole mobile jib 6 is 5mm, and length is 40mm.The circular arc R 6 of anchor pole bottom (5) is 6mm.
To be the conduit back side 3 be connected by welding process with the bottom of anchor pole 5 for contrast accompanying drawing 3, its structure.
Conduit and anchor pole by welding process be connected zinc-plated after, irrigate fixingly with concrete casting, the head of T type bolt is put into the inside of conduit, guarantees that T type bolt can be free to slide in use.
Processing conduit processing step, first hot-roll forming blank, and leave stock left for machining, lubricated cold rolling moulding after pickling then, alkali cleaning, the washing, wherein the material of conduit is Q235, according to its material characteristic, rolling breaking down temperature is decided to be 1050 ℃, and finishing temperature is 750 ℃.
