Abstract
The utility model belongs to the technical field of underground structure engineering, and particularly relates to a top chamber of an underground coal bunker. The top chamber of the underground coal bunker comprises a coal bunker, a chamber and a coal unloading opening, wherein the chamber is arranged across the top portion of the coal bunker, and the coal unloading opening is formed in the top portion of the coal bunker. The top chamber of the underground coal bunker is characterized in that the opening of the chamber structure is closed, the chamber structure is composed of an upper part and a lower part, the lower part below a fracture section is a straight wall, the upper part above the fracture section is a semi-circle arched wall, the lower portion of the straight wall on the side of the chamber is connected with an inclined plate wall, the lower portion of the straight wall on the front of the chamber is connected with a bracket structure, and the bracket structure is connected with a beam. The top chamber of the underground coal bunker has the advantages that advancement volume of the chamber is reduced by 20%, the difficulty of construction and support is decreased greatly, utilization rate is high, and valuable experience is supplied to the design and construction of chambers under same conditions.
Description
(1) technical field
The utility model belongs to the construction of underground structure technical field, particularly top, coal bunker storehouse, a kind of down-hole chamber.
(2) background technology
At present, the coal bunker form mostly is upright cylindrical shape under the coal mine, and the form of its top, storehouse chamber also is cylindrical shape.For the major diameter coal bunker, circular top, storehouse Chamber Construction is complicated, and the supporting difficulty is higher, particularly the supporting of dome.In addition, top, the storehouse chamber utilization rate of circular cross section is lower, is about 30% only, causes very big waste.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of utilization rate height, construction is simple, the supporting difficulty is little top, coal bunker storehouse, down-hole chamber are provided.
The utility model is achieved by the following technical solution:
Top, coal bunker storehouse, a kind of down-hole chamber, comprise coal bunker, stride the chamber of being located at the coal bunker top and be opened in the coal unloading hole at coal bunker top, it is characterized in that: described chamber structure adopts the closing in mode, be that the bottom is that stalk top is that two parts of semicircle arch wall constitute by section, stalk bottom, chamber side is connected with the swash plate wall, stalk bottom, chamber front is connected with bracket structure, is connected with beam on the bracket structure.
Described swash plate wall bottom is connected with the swash plate foundation of wall.
Described beam is provided with the sealing-tape machine basis, and top, sealing-tape machine basis is equipped with sealing-tape machine.
The beneficial effects of the utility model are: chamber driving volume reduces 20%, greatly reduces the difficulty of construction and supporting; The utilization rate height, the design and construction for chamber under the equal conditions provides invaluable experience.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 3 is the B-B face generalized section of accompanying drawing 1;
Among the figure, 1 coal bunker, 2 chambers, 3 coal unloading holes, 4 swash plate walls, 5 bracket structures, 6 beams, 7 swash plate foundations of wall, 8 sealing-tape machine bases, 9 sealing-tape machines.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises coal bunker 1, stride the chamber 2 of being located at coal bunker 1 top and be opened in the coal unloading hole 3 at coal bunker 1 top, chamber 2 structures adopt the closing in mode, be that the bottom is that stalk top is that two parts of semicircle arch wall constitute by section, stalk bottom, chamber 2 side is connected with swash plate wall 4, stalk bottom, chamber 2 front is connected with bracket structure 5, is connected with beam 6 on the bracket structure 5.Swash plate wall 4 bottoms are connected with swash plate foundation of wall 7.Beam 6 is provided with sealing- tape machine basis 8, and 8 tops, sealing-tape machine basis are equipped with sealing-tape machine 9.
Adopt top, coal bunker storehouse, down-hole of the present utility model chamber, changed the form of structure of chamber, adopt the closing in mode, the chamber section of stalk semicircular arch shape.Chamber 2 is across circular coal bunker 1 top, because chamber 2 width are less than coal bunker 1 diameter, stalk bottom, chamber 2 side connects swash plate wall 4, utilizes swash plate wall 4 to accept and transmit the ground pressure that top chamber 2 transmits, and pressure is passed to bottom swash plate foundation of wall 7 through swash plate wall 4.The chamber 2 positive spans that adopt steel concrete bracket structure 5 to shorten chamber 2 beams 6 reduce the physical dimension of beam 6, and bear the pulling force of 9 nearly hundred tons of unloading sealing-tape machines, guarantee the intensity on sealing-tape machine basis 8.
Claims (3)
1. top, coal bunker storehouse, down-hole chamber, comprise coal bunker (1), stride the chamber (2) of being located at coal bunker (1) top and be opened in the coal unloading hole (3) at coal bunker (1) top, it is characterized in that: described chamber (2) structure adopts the closing in mode, be that the bottom is that stalk top is that two parts of semicircle arch wall constitute by section, stalk bottom, chamber (2) side is connected with swash plate wall (4), stalk bottom, chamber (2) front is connected with bracket structure (5), is connected with beam (6) on the bracket structure (5).
2. top, coal bunker storehouse, down-hole according to claim 1 chamber, it is characterized in that: described swash plate wall (4) bottom is connected with swash plate foundation of wall (7).
3. top, coal bunker storehouse, down-hole according to claim 1 chamber, it is characterized in that: described beam (6) is provided with sealing-tape machine basis (8), and top, sealing-tape machine basis (8) is equipped with sealing-tape machine (9).
