Abstract
The invention relates to a mine facility, in particular to a method for mounting mine chute lining steel rails and belongs to the technical field of underground mine equipment. The method comprises the steps of: welding a pre-buried steel plate with anchor bars and steel rails, binding the welded pre-buried steel plate and the steel rails together with a template of a chute top plate to form a bottom die; tying steel bars and pouring concrete on the chute top plate; and synchronously performing the steel rail installation and the construction of the chute top plate structural. The method solves the problems that the operation is inconvenient due to the narrow operation and the installation quality and safety are difficulty ensured. Meanwhile, the construction processes are implemented fluently and incessantly, so the safety problem caused by the cross operation of different work is solved, the construction period is shortened, the project quality and construction safety are guaranteed and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of mine facility, be specifically related to a kind of mounting method of ore chute inner lining steel rail, belong to the colliery technical field of underground.
Background technology
Elevator on the headframe of colliery is promoted to ground with the ore of underground mining, is put in the drop shaft by the ore chute, and the conveyor below drop shaft transports again.Chute is for connecting the slanted channel of ground headframe and underground drop shaft, be reinforced concrete structure, interior periphery is provided with to reducing ore bump and the inner lining steel rail member that rubs, and drop shaft belongs to the ore deposit and builds engineering, and drop shaft inside is provided with to reducing the high manganese steel lining plate member of ore bump and friction.In work progress, the drop shaft bottom is finished by ore deposit 5 constructions of founding the team, and the only remaining preliminary shaft part that is connected with chute is when carrying out the structure construction of the preliminary shaft of drop shaft and chute, at the chute inwall steel plate used of pre-buried welded rails all around.After concrete structure reached the intensity of design, stripping and support system thereof directly were welded in rail on the pre-embedded steel slab again.The chute inclination angle is for being 45 °, headroom is of a size of 3.7 * 2.9 meters, need the rail length of welding to be generally about 10 meters, 24 kilograms/meter, the so heavy and long member of installation on the work plane of narrow and small and inclination, lifting, in place, temporary fixed and installation, operating personnel must face upward the head operation when top board rail was installed, labor strength is big, and also there is potential safety hazard in the rail welding difficult quality guarantee.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of ore chute inner lining steel rail mounting method is provided, earlier will be good with the pre-embedded steel slab and the rail welding of dowel, with the template of chute top board together as bed die, tie up reinforcing bar, build chute top board concrete, rail is installed with the construction of chute top board structure and is carried out simultaneously.Solve invar rail installation exercise narrow space and caused not convenient, installation quality of operation and safety to be difficult for the assurance problem.Construction simultaneously makes the procedure connection compactness, has reduced the safety problem that different professional cross-operation bring, and has saved the duration, has guaranteed workmanship and construction safety, has improved production efficiency.
The present invention realizes with following technical scheme: a kind of ore chute inner lining steel rail mounting method is characterized in that: carry out as follows:
(a) earlier will with the pre-embedded steel slab of dowel and rail welding is good and the template of chute top board together as bed die, tie up reinforcing bar, build the top board concrete of chute, rail is installed with the construction of chute top board structure and is carried out simultaneously;
(b) after the underplate concrete of chute is finished, on base plate, set up the roof plate template bracing frame, highly be rail height of top board soffit decline, earlier on the roof plate template bracing frame, settle rail, then rail and band dowel steel plate are welded, adopt plank and iron wire to hang mould between the rail, form the top board bed die jointly;
(c) treat that concrete roof reaches design strength, remove the bracing frame under the top board, rail just has been fixed on the top board firmly.
(d) there is liner plate the both sides of drop shaft, and chock is arranged at the bottom of chute roof plate template bracing frame.
Advantage of the present invention is: this method is installed rail with the construction of chute top board structure and is carried out simultaneously, solved invar rail installation exercise narrow space and cause that operation is not convenient, installation quality and safety is difficult for the assurance problem.Procedure connection compactness when constructing has simultaneously reduced the safety problem that different professional cross-operation bring, and has saved the duration, has guaranteed workmanship and construction safety, has improved production efficiency.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail:
Accompanying drawing is drop shaft of the present invention, chute structural representation:
Among the figure: 1, rail, 2, embedded board, 3, dowel, 4, thin plank, 5, the roof plate template bracing frame, 6, chock, 7, liner plate, 8, chute, 9, drop shaft.
The specific embodiment
As shown in the figure: a kind of ore chute inner lining steel rail mounting method, carry out as follows:
(a) earlier will with the pre-embedded steel slab 2 of dowel 3 and rail 1 welds and the template of chute top board together as bed die, tie up reinforcing bar, build the top board concrete of chute 8, rail is installed with the construction of chute top board structure and is carried out simultaneously;
(b) after the underplate concrete of chute 8 is finished, on base plate, set up roof plate template and support 5, highly be rail height of top board soffit decline, on roof plate template bracing frame 5, settle rail 1 earlier, then rail and band dowel steel plate are welded, adopt plank and iron wire to hang mould between the rail, form the top board bed die jointly;
(c) treat that concrete roof reaches design strength, remove the bracing frame under the top board, rail just has been fixed on the top board firmly.
(d) there is liner plate 7 both sides of drop shaft 9, and chock 6 is arranged at the bottom of chute roof plate template bracing frame.
