1) builds work stone wall materials barnacle piece in the following thinner seam of the thick about 1.5m of coal and safeguard tunnel, coal-face rear, prepare for next work plane secondary uses.Yet work stone is a fragile material, be subjected to mining pressure after deformation failure serious, maintenance workload is big.2) close standing props and grillage are only applicable to big gun and adopt the thin and medium-thickness seam coal-face of present low gas, and this method is leaked out seriously, and consumption of materials is big, and the roadway maintenance effect is relatively poor, and mechanization degree is low.3) filling of Gao Shui (lotion) quick-set is mainly with multiple materials such as gypsum, lime, fast coagulating early strength agents, mix certain amount of industrial waste residue (as flyash, slag, flue dust, spoil powder etc.) again and be mixed with slurries (or lotion) material, use double-acting pump by pipeline with filler deliver into wait to fill a vacancy between.But this method filler cost is higher, roadside packing body width narrower (being generally 2-3m), bearing capacity deficiency; The filling process complexity, the normal race slurry that occurs reveals the slurry accident; Materials processing and stowage unit cost an arm and a leg etc.

Meanwhile, pollution of ground spoil and mining subsidence also are coal mining industry assistant officer problems to be solved.If will mix the packwall that the spoil particle of cementitious materials is made gob side entry retaining, spoil can not only be turned waste into wealth, solve spoil and pollute and the mining subsidence problem, enough support forces can also be provided.Yet existing templates can not satisfy the demand of this technology fully: traditional lane septate mode plate adopts plank or metal sheet to cooperate individual prop to stop that work stone flows into the tunnel more, and this mode mechanization degree is low, labour intensity big, the speed of setting up is slow, efficient is low.High water or paste body filling stay in the lane, and filling template has two kinds of forms, and the one, cooperate the template of individual prop with steel mesh as moulding; The 2nd, the hydraulic formwork support mainly is adapted to high water between this hydraulic formwork and paste body filling stays in the lane, and to the sealing requirements height, but anti-lateral compression ability is relatively poor, and nothing adds anchor pole muscle function automatically.

Summary of the invention

Order of the present utility model is to provide a kind of lane other extrusion forming template at waste filling gob side entry retaining technology.

Based on this purpose, the utility model has adopted following technical scheme:

Roadside extrusion forming template filled by gangue comprises that the baffle plate of vertical placement and vertical baffle support at its bar behind, and described baffle plate is the longitudinal extension plate.

Described template also comprises an anchor pole fixed head, has notch on it, and the notch place is provided with the anchor pole gripping mechanism; Vertical edge that the anchor pole fixed head is parallel with baffle plate, be detachably connected on baffle plate.

Be provided with the flexible hydraulic jack of control baffle plate in the described baffle plate.

Described push rod is telescopic hydraulic mandril, and higher lateral restriction can be provided.

Described template also comprises base, and base is fixed on the junction of baffle plate and push rod, and base is provided with hydraulic vertical prop, and the column top is fixed with girder steel.Girder steel propped up and stays the lane top board when column rose, to guarantee filling safety.

The multi-stage oil cylinder that the vertical push rod of drive template moves horizontally is installed in the described base, and oil cylinder cooperating face face end support makes template make corresponding mobile with the propelling of work plane.

Formwork structure of the present utility model is simple, the automaticity height, and most parts are Collapsible structure, are convenient to enter underground work.In gob side entry retaining roadside packing moulding (filling waste rock or other solid wastes), can function as follows: 1) anti-lateral compression ability is strong, can provide sufficient restraint forces to obturation, prevent that filling waste rock from flowing in the tunnel in filling and extruding loading procedure, and give the higher intensity of obturation by tunnel one side; 2) baffle plate is the longitudinal extension plate, and retractable is regulated height up and down, with the variation to the obturation requirement for height of the tunnel that adapts to differing heights; 3) the anchor pole fixed head is provided with notch and anchor pole gripping mechanism, is convenient to obturation is applied anchor pole (muscle), further improves the globality and the intensity of packwall; 4) girder steel at column and column top imposes support to back, for job safety provides guarantee; 5) template can reduce labour intensity significantly along the tunnel conveniently moving.
