Description
Technical field
The present invention relates to a kind of rubber packing, particularly to a kind of jacking construction rubber packing and application thereof, belong to municipal works pipe jacking construction technique field.
Background technology
At present, jacking construction, as Non-excavating technology of underground pipeline, has been widely used in the non-excavation laying of the various pipelines such as Urban Underground water supply and sewerage pipeline, natural gas petroleum pipeline, confession distribution cable, communication cable.Being all that merogenesis makes for various push pipe tubing, particularly RC pipejacking, chamber for fibre-reinforced plastics sand inclusion pipe etc., length of pipe section is 2-3m, and when push pipe jacking construction, pipeline section seam need to arrange liner.
This liner one is the top power that can effectively transmit rear; two is to protect pipe end; construct especially for Curve Pipe Jacking; liner also has elimination and the concentrated stress reduced on power transmission face; reducing the effect that top power eccentric throw increases the stability of axis jacking, therefore the material of liner and form are the most important to jacking construction.
The liner of jacking construction uses Masson Pine, Lignum seu Ramulus Cunninghamiae Lanceolatae or plywood mostly at present, for the wooden dunnage of annular used by circular push pipe, general all according to job site processing and fabricatings such as finished product internal diameter of the pipeline, wall thickness, this liner is owing to being annular, employing scene adds expense material of not only taking a lot of work man-hour, product quality also cannot ensure, the hidden danger of quality of pipe joint when causing jacking construction；Curve Pipe Jacking is constructed, owing to tunnel joint corner must be there is, when using wooden dunnage, it is impossible to make pipe end seam total cross-section stress, and outside interface, produce gap, easily make interface occur that stress is concentrated, damage the pipe end of seam by pressure, cause hidden danger of quality.
Summary of the invention
The expense of taking a lot of work that it is an object of the invention to overcome above-mentioned wooden dunnage processing and fabricating expects, cannot damage the weak point of seam pipe end etc. by pressure when products quality guarantee, Curve Pipe Jacking construction; there is provided a kind of energy millwork processing and fabricating, saving material, products quality guarantee, constructing operation is simple, applied widely, optimize the novel liner of pipeline section interface stress performance; when can make jacking construction, pipeline section interface can effectively transmit top power; again can pipe end at protection interface very well, it is ensured that interface quality during jacking construction.
The technical scheme provided according to the present invention, jacking construction rubber packing, including strip-shaped rubber liner and two-sided tape；In the one side being fixed on strip-shaped rubber liner of two-sided tape；Described strip-shaped rubber liner side in the width direction has several equally distributed V-groove mouths.
Described two-sided tape is fixed on the side not having V-groove mouth on strip-shaped rubber liner；Two-sided tape does not contacts with the bottom of V-groove mouth.
The side of the V-groove mouth distance to V-type pocket bottom is not had more than 10mm on described strip-shaped rubber liner.The width of described strip-shaped rubber liner is less than the pipe thickness of push pipe pipeline, and should be suitable for mutually with tube wall.
The thickness of described strip-shaped rubber liner determines according to the diameter of push pipe pipeline or the radius of curvature of Curve Pipe Jacking.The thickness of described strip-shaped rubber liner is 10-30mm.
The spacing of described V-groove mouth determines according to push pipe pipeline；Being 100mm when caliber is less than 1800mm, caliber is to take 200mm during more than 1800mm.
The outside width of described V-groove mouth determines according to push pipe pipeline；It is 75mm when caliber is less than 1800mm, is 150mm when caliber is more than 1800mm.
Described strip-shaped rubber liner material therefor is vulcanie；Two-sided tape is the strong viscous force type adhesive tape of acrylic glue.
Thin film on two-sided tape is opened, two-sided tape is fixed on the side of push pipe pipeline, then by V-groove mouth to push pipe pipe interior bending so that the V-groove mouth being positioned on strip-shaped rubber liner side is gathered, the planar structure consistent with push pipe cross-section of pipeline shape is formed.
Beneficial effects of the present invention:
1, the strip-shaped rubber liner of the present invention can millwork processing and fabricating, improve work efficiency, reduce product cost, also ensure that product quality simultaneously, it is ensured that interface pipe end during jacking construction is not subject to crushing.
2, use bar shaped and open V-groove mouth in side, circular rings, straight-flanked ring or other odd-shaped cross section ring can be bent into, it is adaptable to circular, rectangle or other odd-shaped cross section pipeline, the suitability is more extensive.
3, Curve Pipe Jacking is constructed, owing to opening V-groove mouth in inner side, during jacking, effective lifting surface area of medial pad is less than outside, outside the deformation ratio of inner side greatly, compensate for the inside and outside gap caused because of curve tube segment rotational angle of joint different and make outside unbalance stress problem in tube wall, optimize the stress performance of pipeline section interface, it is ensured that interface quality during jacking construction.
4, two-sided tape is set in strip-shaped rubber liner one side, tears outer layer protection thin film during construction off and be securable to pipe end, simplify constructing operation, reduce difficulty of construction.
