Abstract
A kind of shield structure receives uses sealed soft steel bushing, and steel bushing cylindrical shell is made up of two sections of cylindrical shells, and every section of cylindrical shell is connected to form by the round flange be welded on their bonding surfaces by two pieces of arc splits.By round flange and high strength exploitation rubber ring between two sections of cylindrical shells.Sealing flexible sleeve can alleviate the frictional force, impact force and the stress that cause steel bushing when shield structure receives, plays effective protective effect, thus extends the application life of steel bushing, ensure that the safety that shield structure receives to steel bushing.
Description
Technical field
The utility model belongs to constructing tunnel equipment, particularly a kind of shield structure reception sealed soft steel bushing.
Background technology
In constructing tunnel, when running into rich water sand bed or surrounding enviroment are complicated, it is insecure for only relying on portal rubber curtain fabric swatch and portal pressing plate to carry out sealing to portal, needs to use shield structure reception steel bushing.But the current steel bushing used is when receiving, and because the deadweight of shield structure is heavier, the frictional force, impact force and the stress that cause steel bushing are comparatively large, and steel bushing is easily extruded generation moderate finite deformation, cannot ensure that the safety that shield structure receives and portal seal water-tight,
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art; and a kind of shield structure reception sealed soft steel bushing is provided; sealing flexible sleeve can alleviate the frictional force, impact force and the stress that cause steel bushing when shield structure receives; effective protective effect is played to steel bushing; thus extend the application life of steel bushing, ensure that the safety that shield structure receives.
As above conceive, the technical solution of the utility model is: a kind of shield structure reception sealed soft steel bushing, and steel bushing cylindrical shell is made up of two sections of cylindrical shells, and every section of cylindrical shell is connected to form by the round flange be welded on their bonding surfaces by two pieces of arc splits; It is characterized in that: by round flange and high strength exploitation rubber ring between two sections of cylindrical shells.
The both sides inwall of above-mentioned steel bushing cylindrical shell is separately installed with rail.
The thickness of above-mentioned rubber ring is 20mm.
The utility model has following advantage and good effect:
1. the utility model is owing to passing through between two sections of cylindrical shells to connect flexible rubber ring, change the nonelastic deformation of steel bushing into elastic deformation, therefore the safety of steel bushing be can ensure when shield structure receives, the frictional force and impact force that when shield structure receives, steel bushing are caused alleviated.
2. the utility model can alleviate the stress produced steel bushing when shield structure receives, and ensures that shield structure receives safety.
3. the utility model structure is simple, can extend the application life of steel bushing.
Accompanying drawing explanation
Fig. 1 is use schematic diagram of the present utility model;
Fig. 2 is decomposing schematic representation of the present invention;
Fig. 3 is rubber ring connection diagram.
Detailed description of the invention:
As shown in the figure: a kind of shield structure reception sealed soft steel bushing, steel bushing cylindrical shell 1 is made up of two sections of cylindrical shells, and every section of cylindrical shell is connected to form by the round flange 7 be welded on their bonding surfaces by two pieces of arc splits 9.The thick rubber ring 3 of 20mm is connected by the prepared screw-bolt hole 8 on round flange, flange, high-strength bolt 10 with 10mm thick steel loop plate 11 between two sections of cylindrical shells.Note, water discharging valve 6, exhaust (water) valve 2 is provided with at steel bushing top.The both sides inwall of steel bushing cylindrical shell is separately installed with 140mm rail 5.
Use procedure of the present utility model is:
1, assembled and by flange 4 the utility model is fixed on and receives on portal.
2, shield structure receiving area hydraulic pressure is detected.
3, in the utility model, inject water, pressure is identical or slightly large compared with shield structure receiving area hydraulic pressure.
4, shield structure receives, and release water in the utility model steel bushing, before its pressure is appeared with shield machine, pressure is consistent.
Claims (3)
1. shield structure receives and uses a sealed soft steel bushing, and steel bushing cylindrical shell is made up of two sections of cylindrical shells, and every section of cylindrical shell is connected to form by the round flange be welded on their bonding surfaces by two pieces of arc splits; It is characterized in that: by round flange and high strength exploitation rubber ring between two sections of cylindrical shells.
2. shield structure reception sealed soft steel bushing according to claim 1, is characterized in that: the both sides inwall of above-mentioned steel bushing cylindrical shell is separately installed with rail.
