Abstract
The utility model relates to a technical field is construct to ventilation facility in colliery, specifically is a novel super high dash facility, including building by laying bricks or stones in the brick wall body (3) of drift section, brick wall internal installation air door (9), the top surface of the brick wall body is apart from top of roadway board 2m, build the siding wall body (4) between the brick wall body (3) top surface and the top of roadway board, the siding wall body (4) are including two post (5) being located two post (5) of windward side with be located lee side, and four post (5) constitute two rows promptly, adopt plank (6) fish scale overlap joint to construct into siding wall physically (4) between two rows of posts, the both sides of the siding wall body (4) for the face cement mortar wipe one's face. The utility model relates to a rationally, changing the full section brick of original wall body, sand, cement construction technology into the 2m of top of roadway portion wall body and adopting interim siding wall form to construct, the cement mortar construction of wiping one's face for the face has improved the reliability of ventilation facility, is applicable to very much super high tunnel, has spreading value.
Description
Technical field
The utility model relates to coalmine ventilation facility and builds technical field, is specially a kind of novel super-high dash facility.
Background technology
For the construction of long flat ore deposit along with Modern Pit, it is that modern railless free-wheeled vehicle transports that the means of transportation of mine is progressively evolved by original rail transport, also increasing to the requirement of drift section, at present, the heading sizes in long panel, flat ore deposit four remains essentially between wide 5.2m, high 3.5m-4.5m, the height in part prevailing traffic tunnel is more than 4.5m, even reach 6m, in so high tunnel, how safety constructs permanent ventilation equipment, guarantee the reliability of ventilation equipment, just become urgent problem.
Original ventilation equipment as shown in Figure 1, at whole tunnel end face, builds brick wall body 3 by laying bricks or stones along tunnel outline line 2, in brick wall body 3, install air door 9, and the top being positioned at air door 9 arranges and regulates fan 12, and air door 9 is opened and closed by track 7.Air door 9 is provided with peephole 10 and hand 11, and with air door numbering 8.The shortcoming of this ventilation equipment: the space of body of wall except doorframe all adopts brick, sand, cement to build, places the intensity that double-layer track increases opposite house arch simultaneously on doorframe top.But along with building the continuous rising of height, the erect-position of built, material loading, personnel is also more and more higher, and safety factor will reduce greatly.After air door is built up, under the acting in conjunction of air door upper wall body weight and Tunnel Pressure, in the short time, doorframe upper wall body just occurs that crack is just crushed out of shape, because tunnel is too high, so cause later maintenance difficulty, greatly reduce the safety factor of air door, also affect the quality standardization of facility.
Summary of the invention
There is the continuous rising of building height for when building permanent ventilation equipment in superelevation tunnel, down-hole in the utility model, the erect-position of built, material loading, personnel is also more and more higher, and safety factor reduces greatly; And after air door builds up, under the acting in conjunction of air door upper wall body weight and Tunnel Pressure, in short time, doorframe upper wall body just occurs that crack is just crushed out of shape, the problems such as later maintenance difficulty, build permanent ventilation equipment technique to former superelevation tunnel to improve, have developed the permanent ventilation equipment in a kind of novel super-high tunnel.
The utility model adopts following technical scheme to realize:
The permanent ventilation equipment in a kind of superelevation tunnel, comprises the brick wall body of building by laying bricks or stones in drift section, installs air door in described brick wall body; The end face distance back 2m of described brick wall body, board wall body is built between described brick wall body end face and back, described board wall body comprises two pins being positioned at windward side and two pins being positioned at leeward side, namely four pins form two rows, adopt plank fish scale to overlap between two row's pins and build into board wall body, the two sides cement sand plaster of described board wall body.
Have difficulties for building facility in superelevation tunnel, original ventilation equipment is improved, body of wall top 2m body of wall after improvement adopts interim board wall form to build, the windward side of board wall body and each perpendicular two pins of leeward side, form wall skeleton, adopt plank fish scale to overlap and build into body of wall between pin, plate face cement sand plaster ensures tightly not leak out, technique is simple, greatly reduces the pressure born at doorframe top, builds safety factor and also greatly improve.From economize expense and reduce expend angle calculation, before the comparable improvement of new technology, technique saves cost of materials greatly, and after later stage air door dismounting, new technology is also higher than the material yield rate of old technology.
The utility model is reasonable in design, original body of wall tunneling boring brick, sand, cement are built technique to change top, tunnel 2m body of wall into and adopt interim board wall form to build, at the windward side of body of wall and each perpendicular two pins of leeward side, pin adopts plank fish scale overlap and build into body of wall, plate face cement sand plaster is constructed, substantially increase the reliability of ventilation equipment, be highly suitable for superelevation tunnel, there is promotional value.

Fig. 1 represents the structural representation of original ventilation equipment.
Fig. 2 represents ventilation equipment structural representation described in the utility model.
In figure, 1-entity coal, 2-tunnel outline line, 3-brick wall body, 4-board wall body, 5-pin, 6-plank, 7-track, 8-air door is numbered, and 9-air door, 10-peephole, 11-hand handle, 12-regulates fan.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
The permanent ventilation equipment in a kind of superelevation tunnel, as shown in Figure 2, comprises the brick wall body 3 of building by laying bricks or stones in drift section, installs air door 9 in described brick wall body 3; The top being positioned at air door 9 arranges and regulates fan 12, and air door 9 is opened and closed by track 7.Air door 9 is provided with peephole 10 and hand 11, and with air door numbering 8.
As shown in Figure 2, the end face distance back 2m of brick wall body 3, board wall body 4 is built between described brick wall body 3 end face and back, described board wall body 4 comprises two pins 5 being positioned at windward side and two pins 5 being positioned at leeward side, namely four pins 5 form two rows, adopt plank 6 fish scale to overlap between two row's pins and build into board wall body 4, the two sides cement sand plaster of described board wall body 4.
Balance air door is built for superelevation tunnel, the utility model is built technique to superelevation tunnel and is improved, original brick, sand, cement mixing are built technique to change top, tunnel 2m body of wall into and adopt plank fish scale joint form to build, plate face cement sand plaster construction technology.By above improvement, by original process simplification, reduce the pressure that doorframe top is born, build safety factor and also increase.New technology can save cost of materials greatly than improving front technique, and material yield rate is also high.When back damages top plank by pressure, only need change damaging by pressure plank or remove, simpler than former process maintenance, convenient.
It should be noted last that; above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail with reference to the utility model embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement; do not depart from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
