Abstract
The utility model discloses a cable bridge embedded part for mounting a cable bridge on the side wall of an underground cavern. The cable bridge embedded part is characterized by comprising a cavity box embedded in the structural concrete side wall of the underground cavern, an embedded steel plate is arranged on the outer side of the cavity box and provided with an insertion hole, and the cable bridge is provided with an insertion part matched with the insertion hole. The cable bridge embedded part has the advantages that construction can be simple, convenient and rapid, a construction period is shortened, and construction quality is guaranteed more effectively, and has the greatest advantage of capability of reducing labor cost.
Description
Technical field
The utility model is applicable to the cable testing bridge embedded part that cut and cover tunneling cast-in-situ steel reinforced concrete underground chamber structure is arranged at (comprising roads and tunnels, subway sectional tunnel etc.) side wall.
Technical background
After underground chamber builds up, according to tunnel operation usage requirement, need vertically to lay all kinds of cables along tunnel sidewalls, cable is arranged on the cable testing bridge.
When former method is met this type of situation, generally tunnel main body reinforced concrete build finish and reach certain intensity after, the punching of tunnel sidewalls secondary install crab-bolt with bolt Connecting format installing cables crane span structure or on the side wall embedded part welding cable crane span structure.The method has certain damage such as punching, high-temperature soldering to concrete, and working procedure is many, long in time limit.
The model utility content
The purpose of this utility model is to provide a kind of cable testing bridge embedded part at underground chamber side wall installing cables crane span structure, need not in constructions such as concrete side wall punch, the cable testing bridge that forms product can be inserted the installation that to finish cable testing bridge in the tunnel sidewalls embedded part aperture in the later stage.Adopt this method not only can simple and convenient rapid construction, reduce the duration, and construction quality is more guaranteed, larger advantage is to reduce cost of labor, especially at present cost of labor is higher, and cost of labor will be tending towards showing that further it reduces the advantage of human cost aspect under the higher condition later on.
To achieve these goals, technical solutions of the utility model are: a kind of cable testing bridge embedded part at underground chamber side wall installing cables crane span structure, described cable testing bridge is provided with an inserting member, it is characterized in that the cable testing bridge embedded part comprises the cavity box that is embedded in the underground chamber structural concrete side wall, the outside of described cavity box is provided with a pre-embedded steel slab, and described pre-embedded steel slab is provided with the patchhole that matches with the cable testing bridge inserting member.According to specific embodiment of the utility model, described patchhole is T font hole.The inboard of described pre-embedded steel slab is connected with the reinforcing bar that anchors into side wall concrete.Pre-embedded steel slab also is provided with the weep hole that is communicated with described cavity box.Described inserting member comprise insert steel plate and with the floor of described insertion Plate Welding, described cable testing bridge welds with floor.
The utility model has the advantage of: not only can simple and convenient rapid construction, reduce the duration, and construction quality is more guaranteed, larger advantage is to reduce cost of labor, especially for the Underground Transportation Engineering tunnel, its design length of service is 100 years, and cable testing bridge (the local infiltration in tunnel is common disease under the wet environment condition, and cable is vertically to arrange along the tunnel total length, the cable testing bridge of unavoidable regional area is in wet environment, and this environment is larger on the impact of steel cable bridge durability.) to reach the design period of service with time limits such as tunnels, need to carry out regularly (scaling brush coating etc.) maintaining to cable testing bridge, so not only the duration longer, and to traffic operation affect (such as cable setting and traffic circulation vehicle at the same space).And by this method installing cables crane span structure, its maintaining only needs the cable testing bridge assembly is withdrawed from from fastener inserts, inserts separately new cable testing bridge assembly and can finish.Higher for present cost of labor, and later on cost of labor will be tending towards will showing further that this method reduces the advantage of human cost aspect under the higher condition.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is a kind of cable testing bridge embedded part method, and its methods ﹠﹠ steps of implementation is as follows:
1. when colligation underground chamber side wall reinforcing bar, position in accordance with regulations arranges cable testing bridge fastener inserts 10.Fastener inserts is made in advance, is processed to form product, and it is composed as follows:
1) T font hole 7(is set and is used for inserting the cable testing bridge assembly in the middle of pre-embedded steel slab 5) and draining
Hole 9(is used for getting rid of the water that flows in the reservation cavity box 8);
2) reserve cavity box 8, adopt steel plate to make, with steel plate 5 welding;
3) will anchor into side wall concrete reinforcing bar 6 and steel plate 5 welding;
2. the floor 2 in the assembly 4 is inserted the bottom in " T " font holes 7 in " T " font hole 7 of pre-embedded steel slab 5 that will form the insertion steel plate 1 centering cable testing bridge fastener inserts 10 of plug-in package 4 in the cable testing bridge assembly 11 then.The cable testing bridge assembly is made in advance, is processed to form product, and it is composed as follows:
1) the cable testing bridge 3 general shaped steel processing and fabricatings that adopt, shaped steel can be angle steel, channel-section steel, " worker " word steel, rectangular steel pipe etc., is common product;
2) inserting member is welded to form by inserting steel plate 1 and floor 2;
3) inserting member 4 and cable testing bridge 3 welding are formed cable testing bridge assembly 11.
