Abstract
The utility model provides a small, the convenient lightweight shield constructs to receive uses steel sleeve of transportation, including one section barrel, the barrel includes semicircle components of a whole that can function independently and semicircle components of a whole that can function independently down, goes up semicircle components of a whole that can function independently and semicircle components of a whole that can function independently down and passes through the flange valve snail and tie and link to each other, goes up the semicircle components of a whole that can function independently and is equipped with the end cover at the back with semicircle components of a whole that can function independently down, goes up the semicircle components of a whole that can function independently and is equipped with annular gusset in the semicircle components of a whole that can function independently down, is equipped with the flat gusset of putting in the lower semicircle components of a whole that can function independently. The utility model discloses a steel sleeve novel structure can ensure that the shield constructs the construction and receives safety, has realized steel sleeve miniaturization, transportation installation and has oversimplified, reduces the shield by a wide margin and constructs receipt construction cost.
Description
Technical field
This utility model relates to shield field, is specifically related to the steel bushing used when a kind of shield receives.
Background technology
When the construction of tunnel, door opening, it is necessary to preset an annular steel bushing in portal, when shield machine is from time in portal out, it is directly entered in steel bushing. There is shortcoming in existing steel bushing: volume is big, it is cumbersome to install and transport so that the cost that shield receives is higher. In prior art, steel bushing is long, and what have is divided into three sections, it is necessary to disassemble shield machine again after the whole entrance steel bushing of whole shield machine.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of volume is little, the lightweight shield reception steel bushing of convenient transportation.
The technical solution of the utility model is achieved in that a kind of lightweight shield reception steel bushing, including one section of cylinder, described cylinder includes upper semi-circle split and lower half circle split, upper semi-circle split is connected by flange plate bolt with lower half circle split, it is provided with end cap 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.
Upper semi-circle split, the middle part of lower half circle split and rear portion are provided with sealing ring.
Described wire brush is three roads.
The length of described cylinder is 4000～6000mm.
Steel bushing novel structure of the present utility model, it can be ensured that shield-tunneling construction receives safety, it is achieved that steel bushing miniaturization, transport are installed and simplified, is greatly reduced shield and receives construction cost.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 3 is this utility model sectional view.
Fig. 4 is that this utility model uses view.
Wherein: 1. horizontal gusset, 2. end cap, 3. upper semi-circle split, 4. annular gusset, 5. lower half circle split, 6. reaction frame, portal, 8. wire brush, 9. sealing ring, 10. cutterhead, 11. shield machines, 12. sections of jurisdiction are 7. received.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not paying creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1,2 and 3, a kind of lightweight shield reception steel bushing, including one section of cylinder, described cylinder includes 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, being provided with end cap 2, upper semi-circle split 3 and lower half circle split 5 is provided with annular gusset 4 below for upper semi-circle split 3 and lower half circle split 5, and lower half circle split 5 is provided with horizontal gusset 1.
As shown in Figure 4, when in use, the arrival end of cylinder is connected this utility model with receiving portal 7, and the end cap 2 of cylinder 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 this utility model, described cylinder 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, it is achieved that the requirement of miniaturization, and transport is got up convenient, considerably reduces shield and receives the cost of 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 cylinder 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. Upper semi-circle split 3, the middle part of 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 cylinder and shield machine, it is prevented that water, concrete etc. flow out from its gap.
Preferably, wire brush 8 is three roads.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
