Abstract
The invention provides a light steel sleeve for receiving a shield, and the steel sleeve is small in size and is convenient to transport. The steel sleeve comprises a barrel; the barrel comprises an upper semicircle unit and a lower semicircle unit which are connected by flanges through bolts; an end cover is arranged behind the upper and lower semicircle units; an annular rib plate is arranged on the upper and lower semicircle units; and horizontal plates are arranged on the lower semicircle unit. The steel sleeve is novel in structure, can guarantee the safety of shield reception and construction, is small in size, is easy to transport and install, and greatly reduces the cost for shield reception and construction.
Description
Technical field
The present invention relates to shield structure field, be specifically related to the steel bushing used when a kind of shield structure receives.
Background technology
Tunnel, door opening construction time, need in portal preset an annular steel bushing, when shield machine in portal out time, directly enter in steel bushing.There is shortcoming in existing steel bushing: volume is large, it is cumbersome to install and transport, and the cost compare that shield structure is received is high.In prior art, steel bushing is long, and what have is divided into three sections, disassembles shield machine again after needing that whole shield machine is whole and entering steel bushing.
Summary of the invention
The object of the invention is for above-mentioned the deficiencies in the prior art, provide that a kind of volume is little, the lightweight shield structure reception steel bushing of convenient transportation.
Technical scheme of the present invention is achieved in that a kind of lightweight shield structure reception steel bushing, comprise one section of cylindrical shell, described cylindrical shell comprises upper semi-circle split and lower half circle split, upper semi-circle split is connected by flange plate bolt with lower half circle split, end cap is provided with after upper semi-circle split and lower half circle split, upper semi-circle split and lower half circle split are provided with annular gusset, and lower half circle split is provided with horizontal gusset.
Upper semi-circle split and lower half circle split front end are provided with wire brush.
Middle part and the rear portion of upper semi-circle split, lower half circle split are provided with sealing ring.
Described wire brush is three roads.
The length of described cylindrical shell is 4000 ~ 6000mm.
Steel bushing novel structure of the present invention, can guarantee that shield-tunneling construction receives safety, achieve steel bushing miniaturization, simplification is installed in transport, significantly reduces shield structure and receives construction cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is schematic perspective view of the present invention.
Fig. 2 is schematic front view of the present invention.
Fig. 3 is sectional view of the present invention.
Fig. 4 is using state schematic diagram of the present invention.
Wherein: 1. horizontal gusset, 2. end cap, 3. upper semi-circle split, 4. annular gusset, 5. lower half circle split, 6. reaction frame, 7. receive portal, 8. wire brush, 9. sealing ring, 10. cutterhead, 11. shield machines, 12. sections of jurisdiction.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not paying the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1,2 and 3, a kind of lightweight shield structure reception steel bushing, comprise one section of cylindrical shell, described cylindrical shell comprises upper semi-circle split 3 and lower half circle split 5, upper semi-circle split 3 is connected by flange plate bolt with lower half circle split 5, upper semi-circle split 3 and lower half circle split 5 are provided with end cap 2 below, and upper semi-circle split 3 and lower half circle split 5 are provided with annular gusset 4, and lower half circle split 5 is provided with horizontal gusset 1.
As shown in Figure 4, when in use, the arrival end of cylindrical shell is connected with reception portal 7, and the end cap 2 of cylindrical shell afterbody withstands on reaction frame 6, and cutterhead 10, shield machine 11, section of jurisdiction 12 etc. are arranged in hole, and cutterhead and shield machine progress in steel bushing in the present invention.In the present invention, described cylindrical shell is one section, and its length is 4000 ~ 6000mm, and is divided into upper and lower two parts, and every partial volume is all little than existing, achieves the requirement of miniaturization, and transport is got up convenient, considerably reduces the cost that shield structure receives construction.
Upper semi-circle split 3 and lower half circle split 5 front end are provided with wire brush 8, and when shield machine enters cylindrical shell time, a part of foreign material etc. can be adhered in shield machine surface, and now wire brush 8 can clean the foreign material on shield machine surface.The middle part of upper semi-circle split 3, lower half circle split 5 and rear portion are provided with the sealing ring 9 of rubber, and sealing ring is for realizing the sealing between cylindrical shell and shield machine, and anti-sealing, concrete etc. flow out from its gap.
Preferably, wire brush 8 is three roads.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
