Abstract
The utility model discloses a shed erection support at an underground fork or a tunnel opening. The shed erection support comprises a first close-leg shed (3) and a second close-leg shed (4) combined by every two close legs of a U shed (1), and an I-shaped steel beam (5), wherein a wire mesh (7) and wood back plates (8) are laid on the shed top of a temporary U shed (2); and the shed erection support is characterized in that the first close-leg shed (3) is connected with the second close-leg shed (4) through the I-shaped steel beam (5); and the temporary U shed (2) is arranged between the first close-leg shed (3) and the second close-leg shed (4). According to the shed erection support, the compressive capacity of the fork and opening positions can be greatly improved, the shed erection support is widely applied in underground coal mine production, a safe and reliable guarantee is provided for underground important fork repair and long-distance later tunnel advancement, and the shed erection support has safe and practical significance.
Description
Technical field
The utility model relates to novel specification and lifts the canopy supporting and be applied to coal mine down-hole tunnel fork or support technology field, laneway opening position.
Background technology
Along with the pit mining time is longer, mine causes pressing and increases because of the open a mine increase of the degree of depth of coal seam, and the fork, tunnel reprocesses and newly dig in the laneway opening work progress, during roof cracking, when adopting anchor/rope/net supporting, do not reach the design supporting effect, cause potential safety hazard, cause the tunnel to be done over again.Therefore, fork, tunnel or laneway opening position support form are insoluble technical problems.
Summary of the invention
The technical problems to be solved in the utility model:A kind of Novel tunnel fork or laneway opening position supporting are provided, namely lift the canopy supporting, when solve adopting anchor/rope/net supporting, do not reach the technical problem of design supporting effect.
The technical solution of the utility model: a kind ofly lift the canopy supporting for fork, down-hole or laneway opening position, comprise: the U canopy joins legs in twos and is combined into join legs U canopy one and the U canopy two that joins legs, steel I-beam, interim U canopy ceiling arranges wire gauze and plank lagging, the U canopy one that joins legs connects by steel I-beam with the U canopy two that is connected, and interim U canopy is located at the U canopy one and joining legs between U canopy two of joining legs.
Described interim U canopy must exceed join legs U canopy one and U canopy two 300mm that join legs, and interim U canopy canopy distance is 700mm.
Describedly begun by opening or fork side, on the capplce of U canopy one and the U canopy two that joins legs that joins legs, the steel I-beam of 5,4,4,2 group is set respectively successively, every group of steel I-beam spacing 600mm, and use U-shaped canopy canopy to fasten steel I-beam.
The beneficial effects of the utility model: the utility model is lifted the canopy supporting can larger raising fork and aperture position anti-pressure ability, be used widely in the downhole production of colliery, reprocessing and grow apart from tunnel later stage driving for emphasis fork, down-hole provides safety, reliable guarantee, has very safe, practical significance.
Description of drawings
Fig. 1 is aperture position of the present utility model when being designed to anchor rod laneway, aperture position supporting plan view;
Fig. 2 is aperture position of the present utility model when being designed to anchor rod laneway, aperture position supporting sectional drawing;
Fig. 3 is aperture position of the present utility model when being designed to hacking shed tunnel, aperture position supporting plan view;
Fig. 4 is aperture position of the present utility model when being designed to hacking shed tunnel, aperture position supporting sectional drawing.
The specific embodiment:
By reference to the accompanying drawings, when the utility model solve is adopted anchor/rope/net supporting, do not reach the technical problem of design supporting effect, the technical scheme of taking is done following explanation:
Its static mounting structure: ask for an interview accompanying drawing: the utility model is mainly by to canopy one, consist of canopy two, interim canopy, steel I-beam.
Concrete implementation step is as follows:
(1) generally at the fork or the aperture position either side first set up the U canopy 1 that joins legs (specifications and models: the upper clear span of lower clear height *=5.05m*3.1m);
(2) then set up interim U canopy 2 (specifications and models: the upper clear span of lower clear height *=4.5m*3.2m) by frame successively toward U canopy 24 directions that join legs, the canopy distance is 700mm, notice that interim U canopy 2 must exceed the U canopy 300mm that joins legs, after the U canopy 24 of being convenient to join legs sets up, intert steel I-beam 5 on joining legs the U capplce at two groups;
(3) set up the U canopy 24 that joins legs behind U canopy 24 positions of joining legs;
(4) two join legs after U canopy 3,4 establishes, begun by opening or fork side, successively on the U canopy 3 that joins legs, 4 capplces respectively by 5,4,4,2 one group, interspersed the 1st group ~ the 4th group leader 6.2m11# mining i beam beam 5, every group of i iron spacing 600mm, amount to 15, steel I-beam 5 is lifted canopy lap length 500mm with every group, and lap-joint is fixing with a secondary U-shaped canopy canopy card 6, prevent that steel I-beam 5 from sliding, insert between beam with wooden gallows timber interlocking.
(5) after steel I-beam 5 is put on, remove join legs interim U canopy 2 canopy legs between U canopy 3,4 of open side two.
(6) lift on ceiling and to adopt 10# wire gauze 7(specification: long * is wide=3.0m*0.9m) coordinate round log, half round timber and plank lagging 8 to carry on the back to establish tight, and wire gauze 7 lap length are 100mm, and wire gauze 7 lap-joints network with the 12# iron wire; Plank lagging 8 is along lane layout and spacing≤500mm, and empty very useful round log or half round timber are beaten grillage and connect the top.
