Chamber 100 according to embodiments of the present invention is described below with reference to Fig. 1.
As shown in figure 1, chamber 100 according to embodiments of the present invention, the inside of chamber 100 limits horizontally extending
Tunnel 10, tunnel 10 includes upper space 10a and lower space 10b, and upper space 10a is interconnected with lower space 10b,
Upper space 10a is located at lower space 10b top, and upper space 10a width is more than lower space 10b width.
Further, lead to respectively between the upper space 10a and lower space 10b of the both sides of tunnel 10 in the direction of the width
Cross junction to be connected, be respectively formed with upward step surface 10c two junctions, crane girder 40 and lifting in chamber 100
Machine 50 is located in upper space 10a, and the both ends of crane girder 40 are respectively supported on the step surface 10c of both sides, using in chamber 100
The support of lower space 10b side walls section or country rock 20 as crane 50 so that the space of chamber 100 is fully utilized, and improves
Chamber 100 scetion utilization, the increase of plane effective area.
Chamber 100 according to embodiments of the present invention, by the both sides of tunnel 10 in the direction of the width in upper space 10a and
Lower space 10b junction forms upward step surface 10c respectively, and so, the both ends of crane girder 40 may be supported on both sides
Step surface 10c on, independent supporting construction need not be set in chamber 100, simplify the supporting construction in chamber 100, fully
Using the space of chamber 100, furthermore it is possible to effectively reduce the overall span of chamber 100, the excavated volume and supporting material of chamber 100
The consumption of material is reduced, and is advantageous to accelerate the engineering construction progress of chamber 100.
According to one embodiment of present invention, the side wall of tunnel 10 in the direction of the width includes the first vertical section 11, transition
Section and the second vertical section 12, the first vertical section 11, changeover portion and the second vertical section 12 are sequentially connected to form tunnel 10 from top to bottom
Side wall, limit upper space 10a between two relative the first vertical sections 11 in the direction of the width, it is relative on width
Two the second vertical sections 12 between be lower space 10b, pass through changeover portion between the first vertical section 11 and the second vertical section 12
It is connected, changeover portion is configured to step surface 10c.
Thus, the both ends of crane girder 40 can be respectively supported at step surface by the step surface 10c formed by changeover portion
10c is upper, is achieved in that the support to crane 50, eliminates supporting construction special in correlation technique, simplifies chamber
100 supporting construction, and the support to crane 50 is very reliable.
As shown in figure 1, according to the optional example of the present invention, the height of the first vertical section 11 is less than the second vertical section
It 12 height, can so ensure that step surface 10c is located at predetermined height, while crane 50 is supported on to predetermined height,
It is easy to sling weight, in addition, by the way that the height of the first vertical section 11 is set smaller than into the height of the second vertical section 12, can reserves
More lower space 10b are easy to manually be operated.
Reference picture 1, according to another optional example of the present invention, the roof 13 in tunnel 10 arches upward to form arch upwards
Portion, getting off for crane 50 can be so avoided to be close to the roof 13 in tunnel 10, i.e. the dolly of crane 50 can be in arch portion
Interior carry out activity, sufficient space is left for the operation of crane 50, further, it is also possible to reduce the overall span of chamber 100, just
In the excavation to chamber 100, be advantageous to tunneling construction.
As shown in figure 1, according to the further example of the present invention, the longitudinal section of the roof 13 in tunnel 10 is formed as arch, such as
Can be circular arc, three-core arch or Semicircular arched etc., with specific reference to the shape that carries out selected tunnel 10 is actually needed, by lane
The roof 13 in road 10 limits arch portion, simple in construction, stably, good appearance, and reduces the overall span of chamber 100, drops
The low driving amount and consumption of materials of country rock 20.
According to another embodiment of the invention, step surface 10c is formed as plane, i.e., the both ends difference that crane girder 40 supports
It is supported in the plane of both sides, by the way that the both ends of crane girder 40 are only against in the plane of both sides respectively, for carrying crane girder
40 and the weight of crane 50.
According to still another embodiment of the invention, step surface 10c is formed as concave surface, i.e., the both ends difference that crane girder 40 supports
It is supported on the concave surface of both sides, by the way that the both ends of crane girder 40 are only against on the concave surface of both sides respectively, for carrying crane girder
40 and the weight of crane 50, and the both ends of crane girder 40 are located on concave surface, can avoid crane girder 40 in the width in tunnel 10
It is movable on direction so that total is more stable, reliable.
According to optional embodiment of the present invention, the upper space 10a and lower space 10b in tunnel 10 hollow out by country rock 20
Form, wherein step surface 10c is made up of country rock 20, specifically, the top sky for forming tunnel 10 is tunneled by the way that country rock 20 is hollowed out
Between 10a and lower space 10b, using country rock when tunneling 20 formed step surface 10c, so, be applied not only to support the He of crane girder 40
The structure of crane 50 reliably, stably, and saves independent supporting construction, significantly simplify supporting construction.
Alternatively, by being provided with concrete supporting 30 on the internal face in tunnel 10, concrete supporting can be caused
30 are bonded on country rock 20, play a part of supporting country rock 20, and then strengthen the structural stability in tunnel 10, improve simultaneously
The enabling capabilities of itself of country rock 20, in addition, branch sheath 30 can completely cut off contact of the empty gas and water with country rock 20 completely, strengthen and enclose
Rock 20 and the intensity in whole tunnel 10.
Supporting construction of the chamber 100 by the use of lower space 10b side walls section as crane 50 in the present invention so that chamber
100 space is fully utilized, and improves the scetion utilization of chamber 100, adds plane effective area, lower space 10b
Width reduce, save the driving amount of country rock 20 and support material consumption, without setting the single supporting upright post of crane 50,
And excavated section is smaller, thus accelerate construction speed.
Other of chamber 100 according to embodiments of the present invention are formed and operated for those of ordinary skills
