Abstract
The utility model discloses a totally-enclosed U-shaped shed support frame for roadway supporting, which is characterized by consisting of a reversed U-shaped supporting frame (1) for supporting the roadway top, the roadway side portion and the roadside and reversed bottom arches (2) connected at two ends of the bottom of the reversed U-shaped supporting frame. Both the U-shaped supporting frame (1) and the reversed bottom arches (2) are formed by connecting a plurality of arch support frames (3) mutually, the reversed bottom arches (2) are arranged under a roadway bottom plate (4), and gangues are filled between the reversed bottom arches (2) and the bottom plate (4) to serve as a filling layer (5). The totally-enclosed U-shaped shed support frame forms a totally-enclosed supporting whole, supporting strength, especially the supporting strength of the bottom plate can be enhanced, phenomena including top falling, rib spalling, bottom heave and the like of the roadway are prevent, potential safety hazards are eliminated, repeat repair of the roadway is avoided, and manpower and material resources are saved.
Description
Technical field
The utility model relates to a kind of mine laneway supporting instrument, specifically a kind of totally-enclosed U type roadway support canopy.
Background technology
Along with the continuous increase of the coal mining degree of depth, the tunnel is in the higher ground stress environment, and deformation of the surrounding rock in tunnel is violent; Supporting is difficulty further; Cause the tunnel unstable failure, grow more in the regeneration crack, causes very difficulty of tunnelling construction and supporting; Need to repeat to overhaul the tunnel, serious threat mine safety is produced regularly.Existing roadway support instrument only carries out supporting to top, tunnel and portion of group, and base plate is had no support action, can not form totally-enclosed supporting to the tunnel, so just can't avoid tunnel pucking phenomenon.
The utility model content
The utility model is the weak point that exists for fear of prior art, and a kind of totally-enclosed U type canopy support is provided; Through increasing the arch of the anti-end of special supporting roadway floor, strengthen supporting, and then form the whole totally-enclosed supporting of the full section in tunnel to base plate, to strengthen the whole supporting intensity in tunnel, eliminate safe hidden trouble, avoid repetition maintenance tunnel.
The utility model technical solution problem adopts following scheme:
A kind of roadway support is with totally-enclosed U type canopy support; Its design feature is; Form by inverted U supporting frame that is used for top, supporting tunnel, sidepiece and lane group and the arch of the anti-end that is connected two ends, inverted U supporting frame bottom; Said U type supporting frame and arch of the anti-end are interconnected to form by a plurality of arch supports, and arch of the said anti-end is located at the roadway floor below, between arch of the said anti-end and base plate, are filled with the moderate spoil of granularity as packed layer.
The utility model design feature also is: all adopt double flute clamping plate upper limit card cable, double flute clamping plate lower limit card cable and the middle clamping plate card cable that is provided with to be fixedly connected between each connected node of said totally-enclosed U type canopy support.
Compared with present technology, the utility model beneficial effect is embodied in:
The utility model uses anti-end arch (totally-enclosed U type canopy) in high stressed soft rock tunnel, deep, base plate is carried out special supporting, and it is whole that the tunnel is formed a totally enclosed supporting; Can strengthen supporting intensity, particularly strengthen the base plate supporting intensity, prevent that the tunnel from falling phenomenons such as top, wall caving, pucking; Eliminate safe hidden trouble; Avoid repetition maintenance tunnel, use manpower and material resources sparingly, have considerable economic and social benefit.
Description of drawings
Fig. 1 is the utility model structural representation.
Label among the figure: 1 is that U type supporting frame, 2 is that arch of the anti-end, 3 is that arch support, 4 is that base plate, 5 is packed layer, 6 double flute clamping plate upper limit card cables, 7 double flute clamping plate lower limit card cables, 8 therebetween integrated circuit board cables.
The specific embodiment
The utility model is further specified through embodiment below in conjunction with accompanying drawing.
Referring to accompanying drawing 1; Form by inverted U supporting frame 1 that is used for top, supporting tunnel, sidepiece and lane group and the arch of the anti-end 2 that is connected two ends, inverted U supporting frame bottom; U type supporting frame 1 and arch of the anti-end 2 are interconnected to form by a plurality of arch supports 3; Arch of the anti-end 2 is located at roadway floor 4 belows, between arch 2 of the anti-end and base plate 4, is filled with the moderate spoil of granularity as packed layer 5.All adopt double flute clamping plate upper limit card cable 6, double flute clamping plate lower limit card cable 7 and therebetween integrated circuit board cable 8 to be fixedly connected between each connected node with upper bracket.
In the practical implementation, after the tunnel excavates, adopt to possess can the contract totally-enclosed U type steel shed support of characteristic of high resistant, canopy is apart from 500mm, and the support lap length is 500mm, and adopts the upper and lower spacing card cable of double flute clamping plate and 1 pair of common clamping plate card cable.On design base plate absolute altitude basis, peel off the fragmented rock body about 1000mm downwards.Set up arch trestle of the anti-end; The canopy distance is identical with the U shape steel bracket; Be used the high-strength anti-skid steel mesh reinforcement, between anti-end arch joint and the joint and arch of the anti-end is connected the common clamping plate card cable fixed connection of all adopting the upper and lower spacing card cable of double flute clamping plate and 1 pair of middle setting with support canopy leg.After bow member of the anti-end was established and finished, the spoil that the base plate filling granularity between arch of the anti-end and design base plate absolute altitude is moderate was as packed layer.
