Abstract
The utility model discloses a composite supporting structure of a roadway, which comprises a cable anchor and a U-shaped steel arched shed which is arranged at the inner side of the cable anchor. Long-strip gaps which extend along the roadway are formed between the two sides of the cable anchor which bend outwards and the U-shaped steel arched shed. After the roadway is deformed for the first time, the gaps at the two sides of the roadway release stress; before the secondary stress occurs, the shed columns of the supporting structure of the U-shaped steel arched shed are used for supporting, thereby prolonging the secondary supporting time, effectively resisting the pressure, preventing the shed legs of the supporting structure of the U-shaped steel arched shed from being deformed and drilling the bottom, therefore, improving the service life of the roadway and improving the safety of using the roadway.
Description
Technical field:
The utility model relates to a kind of roadway support structure, especially a kind of tunnel composite support structure.
Background technology:
Employed in the tunnel on the colliery at present is anchor rete cord+U shaped steel arched roof supporting and protection structure, this supporting and protection structure and the trapezoidal canopy supporting and protection structure of i iron is the more effective renitency of specific energy mutually, but near the tunnel of work plane that is subjected to mining influence still has very big deflection, cause the section in tunnel to dwindle, the roadway surrounding rock extruding inevitably takes place make distortion of canopy leg and canopy leg bore end accident, the influence safety in production.
The utility model content:
The purpose of this utility model provides a roadway support structure, and effective renitency prolongs tunnel service time, improves the safety of producing.
In order to solve above-mentioned purpose, the technical scheme that the utility model adopted is: a kind of tunnel composite support structure, comprise the anchor rete cord and be arranged on the U shaped steel arched roof of anchor rete cord inboard, described anchor rete cord both sides outwardly-bent with U shaped steel arched roof between be arranged with the strip space of moving towards extension along the tunnel.
Described gap length is a 0.3-0.5 rice, highly is 2-2.5 rice.
Advantage of the present utility model is: anchor rete cord that the utility model adopted and U shaped steel arched roof composite support structure, be provided with two in anchor net both sides between the outwardly-bent and U shaped steel arched roof and move towards the strip spaces of extending along the tunnel, after the tunnel once is out of shape, space by the both sides, tunnel discharges stress, before secondary stresses arrives, utilize the canopy post supporting of U shaped steel arched roof supporting and protection structure, prolong the secondary supporting time, effectively resisted pressure, avoided the distortion of canopy leg and the canopy leg of U shaped steel arched roof supporting and protection structure to bore end accident, thereby prolonged the service time in tunnel, improved the safety that use in the tunnel.
Description of drawings:
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment:
As shown in Figure 1, wherein 4 is the country rock in tunnel, and 8 is the ground in tunnel, and anchor net 9 is fixed on composition anchor rete cord on the roadway surrounding rock 4 by anchor cable 1 and the anchor pole 2 of squeezing into roadway surrounding rock 4; Arched roof 7 connects to form the supporting of U shaped steel arched roof with canopy leg 5 by pin 6; Be symmetrically arranged with two between the outwardly-bent and canopy leg 5 in described anchor net 9 both sides and move towards the strip spaces 3 of extending along the tunnel, space 3 width are 0.4 meter, highly are 2.4 meters.After the tunnel once is out of shape, discharge stress by the space 3 of both sides, tunnel, before secondary stresses arrives, utilize the canopy post 5 of U shaped steel arched roof supporting to support, prolong the secondary supporting time, effectively resisted pressure.
Claims (2)
1, a kind of tunnel composite support structure is characterized in that: comprise the anchor rete cord and be arranged on the U shaped steel arched roof of anchor rete cord inboard, described anchor rete cord both sides outwardly-bent with U shaped steel arched roof between be arranged with the strip space of moving towards extension along the tunnel.
2, tunnel according to claim 1 composite support structure, it is characterized in that: described gap length is a 0.3-0.5 rice, highly is 2-2.5 rice.
