Abstract
The utility model relates to a U-shaped shed support in-binding structure, which comprises a U-shaped shed, wherein the leg parts of the U-shaped shed are vertical downwards, and anchor rods which extend to a coal seam and are used for reinforcing are respectively arranged on the leg parts on two sides of the U-shaped shed. Each anchor rod is fixed with each U-shaped shed leg through a buckle. The U-shaped shed support in-binding structure is adopted for in-binding the U-shaped shed structure, the original roadway does not need to be opened, and the support of the original roadway cannot be damaged. The leg parts and the wall of the roadway are fixed together to form a stable structure, and the operation is simple and effective. A mode that the buckles are additionally arranged at the leg parts of the U-shaped shed is utilized for fixing, so that the problems that the shed strength is reduced, the shed is inconveniently used repeatedly and the like caused by perforation at the leg parts of the U-shaped shed can be avoided. The support strength of the roadway is increased, and the situations of the leg parts of U-shaped steel being damaged are effectively reduced. At present, the U-shaped shed structure is tried out at multiple diggings, the support effect is good, and the U-shaped shed structure has a higher popularization and application value.
Description
Technical field
The utility model belongs to the improvement technology of U type canopy supporting, is specifically related to be-the interior structure of pricking of kind of U type canopy supporting.
Background technology
The colliery underworkings is production and transport and pedestrian's a escape way, must guarantee to be perfectly safe with the lane protect relatively stable.Along with the transition of age development; The underworkings support process obtains bringing in constant renewal in the Coal Production practice and develops; Develop into present steel supporting and anchor pole wire lath gunite structure gradually by original mine timber supporting and protection structure; The supporting power that its lane is protected also constantly is enhanced along with the change of supporting and protection structure, and security and stability tunnel up to standard for the mine quality standardization played crucial effects.
My ore deposit is unstable to top board, and big tunnel is pressed in the ore deposit, mainly adopts the support canopy supporting of compressive property U shaped steel self-control preferably processing; Because factors such as roadway surrounding rock fragmentation; Tunnel roof pressure, side pressure are all bigger, though compressive property preferably U type canopy specification change the supporting canopy supporting of 29U shaped steel processing into by original 25U shaped steel in continuous amplification; Existing some areas have begun to use the supporting of 36U shaped steel; But still have many support canopies to be bent, and 90% above bending all occurs in the shank (mainly be reflected as down leg bending in prick) of canopy supporting stringcourse below 1 meter, cause empty top of capplce to be twisted by top board; The entire bracket canopy still loses support force, threatens the safety in tunnel.In view of the foregoing, of Fig. 1 for coal road road driving and expand and repair my ore deposit U type canopy supporting of tunnel and mainly adopt the supporting of outer bundle type U type canopy, prick angle outward and be generally 10 and spend, played effect preferably; But it is less for part anchor net spray roadway deformation; The tunnel of tunnel top section laitance coating cracking; Adopt outer bundle type U type canopy just must open group, destroy original roadway support, if adopt the supporting of stalk semicircle arch U type canopy original tunnel; Then along with the continuous increase of mine pressure, shank then becomes the weak area of distortion.
The utility model content
The purpose of the utility model is the weak point that overcomes in the prior art, provides a kind of simple in structure, and stressed evenly stability is strong, and is easy to use, pricks structure in the effective U type canopy supporting.
Technical scheme: prick structure in the supporting of a kind of U type canopy, comprise U type canopy, the shank of this U type canopy is respectively arranged with on the shank of U type canopy both sides and stretches to the anchor pole that the coal seam is used to reinforce straight down.
Each anchor pole is vertical with U type canopy two side legs.Adopt card blue fixing between each anchor pole and the U type canopy supporting leg.
The blue structure of said card is and the U type structure of U type canopy surface configuration approximate match that the blue both sides of this U type structure card are provided with the flange of symmetry, and the anchor pole jack is set on the flange.Said anchor pole jack be shaped as circular or semicircle or shapes such as oval or regular polygon.Said anchor pole adopts resin anchor.
Beneficial effect: adopt and to prick U type booth structure in the utility model and need not group is opened in original tunnel, can not destroy the supporting in original tunnel, and shank and the wall formation rock-steady structure that is fixed together, simple to operate effective.Being utilized in U type canopy shank adds the blue mode of card and fixes; Can avoid causing problems such as canopy body intensity descends, is inconvenient to reuse in the punching of U type canopy shank; Improved roadway support intensity, reduced U shaped steel shank destruction situation effectively and taken place, this U type booth structure is on probation in a plurality of mining areas at present; Supporting effect is good, has higher popularization and application values.
Description of drawings
Fig. 1 is existing outer bundle type U type booth structure sketch map;
Fig. 2 pricks U type booth structure sketch map in the utility model;
Fig. 3 is that resin anchor cooperates the blue fixedly structural representation of U type canopy shank of card.
Label 1 is a U type canopy among the figure, and 1a is that U type canopy is pricked shank outward, and 1b pricks shank in the U type canopy, and 2 is vertical anchor pole, and 3 are the card orchid.
The specific embodiment
Embodiment one: referring to Fig. 2, prick structure in the shank of U type canopy 1 forms straight down, on the shank 1b of U type canopy 1 both sides, be respectively arranged with and stretch to the anchor pole that the coal seam is used to reinforce.Each anchor pole is vertical with U type canopy two side legs.Referring to Fig. 3, adopt card blue 3 fixing between each anchor pole and the U type canopy supporting leg.The structure of card blue 3 is and the U type structure of U type canopy shank 1b surface configuration approximate match that the blue both sides of this U type structure card are provided with the flange of symmetry, and the anchor pole jack is set on the flange.Wherein, the shape of anchor pole jack can be circle or semicircle or shapes such as oval or regular polygon.Bolthole and anchor pole external appearance matching, anchor pole 2 adopts resin anchor.
Claims (6)
