Abstract
The utility model discloses a burden ring canal mould apron with locating lever, including the apron body, its characterized in that: the anchor ring is equipped with the locating lever in the apron body, uses the outer anchor ring of the negative ring canal of burden ring canal mould apron production is fluted, can be fixed with the location round steel cooperation that the shield constructs bottom the quick -witted shield tail. Use the negative ring canal of section of jurisdiction mould production of negative ring canal mould apron, when shield structure machine starts, can with the shield construct two of quick -witted shield tail bottom fix a position round steel mutually support fixed, accurate location in the shield tail to ensure that the shield constructs the accurate of quick -witted direction of advance, improves construction quality, and the utility model discloses simple structure installs and removes the convenience, is suitable for extensive popularization and application.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of pipe die cover plate with backstay.
Background technology
Along with the development in city, the density of population is increasing, and traffic pressure also increases thereupon, and in order to alleviate traffic pressure, the development of the underground engineering being representative with subway, tunnel can be more and more faster.Shield method has the advantage that efficiency of construction is high, control bottom effect of settling is good, extensive use in constructing metro tunnel because of it.
During shield launching, starting in working shaft, the rear end of shield machine is a reaction frame (providing the back of counter-force), ring-type section of jurisdiction is installed between reaction frame and shield structure jack, to tunnel the active force of pushing ahead to shield machine, until the shield tail of shield machine is entered the hole of borehole wall opposite side.During shield launching, assembled first ring is born endless tube sheet and is difficult to precise positioning in shield tail, has a strong impact on section of jurisdiction attitude, and existing negative endless tube sheet is all produced by standard endless tube die, can not meet location requirement.
Utility model content
The purpose of this utility model there is provided a kind of pipe die cover plate with backstay, for the production of the negative endless tube sheet with positioning function, so that precise positioning shield machine.
To achieve these goals, the technical solution adopted in the utility model is as follows:
With a negative endless tube die cap plate for backstay, comprise cover board body, described cover board body inner ring surface is provided with backstay, and the outer ring surface of the negative endless tube produced with described negative endless tube die cap plate is fluted, can coordinate fixing with the location round steel bottom shield machine shield tail; Thus the hoop of fixing negative endless tube sheet at shield tail place and lengthwise position, ensure the accurate of shield machine direction of advance, be of value to and improve tunnel quality.
Preferably, described backstay has two, is located at the both sides of described cover board body inner ring surface respectively, the distance of described two backstays, consistent with two distances of locating round steel bottom described shield machine shield tail.
Preferably, described backstay is connected with described cover board body by removable connector, can carry out design alternative according to the size of different model shield machine shield tail.
Preferably, described cover board body and described backstay are provided with counterbore and bolt hole successively, described backstay and described cover board body are bolted.
Preferably, described backstay is connected by key with described cover board body.
The beneficial effects of the utility model:
(1) the negative endless tube that the segment die of negative endless tube die cap plate described in the utility model is produced is used, when shield launching, locate round steel with two bottom shield machine shield tail piece and cooperatively interact fixing, precise positioning in shield tail, thus guarantee the accurate of shield machine direction of advance, improve construction quality.
(2) backstay described in is secured by bolts in described cover board body inner ring surface, and be convenient to installation and removal, and can not affect the pouring quality of section of jurisdiction, described backstay can carry out design alternative according to the size of different model shield machine shield tail.
And the utility model structure is simple, mounting or dismounting are convenient, are suitable for wide popularization and application.
Accompanying drawing explanation
Fig. 1 is part section structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, a kind of negative endless tube die cap plate with backstay, comprise cover board body 1, described cover board body 1 inner ring surface both sides are respectively equipped with backstay 2, the distance of described two backstays 2, consistent with two distances of locating round steel bottom described shield machine shield tail, the outer ring surface of the negative endless tube that the segment die being equipped with described negative endless tube die cap plate is produced is fluted, can coordinate fixing with the location round steel bottom shield machine shield tail.
In order to backstay 2 is installed and removed conveniently, backstay 2 is connected with described cover board body 1 by removable connector, in the present embodiment, can be bolted, described cover board body 1 and described backstay 2 are provided with counterbore 3 and bolt hole 4 successively, described bolt hole 4 is blind hole, and described backstay 2 is connected by bolt 5 with described cover board body 1, can not affect the pouring quality of negative endless tube sheet.Described backstay 2 adopts easy mounted-dismounted type, can carry out design alternative according to the size of different model shield machine shield tail.
As shown in Figure 2, every root backstay 2 both sides are all bolted, more stable, ensure the pouring quality of negative endless tube sheet.
Claims (5)
1. the negative endless tube die cap plate with backstay, comprise cover board body, it is characterized in that: described cover board body inner ring surface is provided with backstay, the outer ring surface of the negative endless tube produced with described negative endless tube die cap plate is fluted, can coordinate fixing with the location round steel bottom shield machine shield tail.
2. the negative endless tube die cap plate with backstay according to claim 1, it is characterized in that: described backstay has two, be located at the both sides of described cover board body inner ring surface respectively, the distance of described two backstays, consistent with two distances of locating round steel bottom described shield machine shield tail.
