Abstract
The invention discloses a kind of bridge shrinking cracks jumpings to prevent construction method, belong to bridge technology field, if the present invention paves and rolls condition by secondary excavation, pre-buried dried layer casing and using what fiber concrete filled etc. that techniques greatly improved concrete near expansion joint, it can guarantee its compactness, reduce height difference caused by vehicle effect secondary compaction；Also the tensile strength of the neighbouring concrete in expansion joint is strengthened, reduce the air shrinkage value of concrete, effectively improving expansion joint, nearby concrete cracking, drying shrinkage happen, and then are effectively improved bumping at bridge-head situation.
Description
Technical field
The present invention relates to a kind of bridge shrinking cracks jumpings to prevent construction method, belongs to bridge technology field.
Background technology
Extension joint refers to deformation around expansion joint, fracture or even pit slot, so as to influence the normal use of bridge, together
When also influence traffic safety, speed, comfortable and its service life.For Extension joint, expansion joint jump how is effectively eliminated
Vehicle or the minimum level that vehicle reduction will be jumped, it has also become urgent problem to be solved in bridge maintenance.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of bridge shrinking cracks jumping prevention construction method.
To achieve the above object, the present invention provides a kind of bridge shrinking cracks jumping prevention construction method, including following step
Suddenly,
Step 1: milling bridge floor and cutting the expansion joint adjacent with bridge floor so that milling and the part cut form one
A groove body, the expansion joint are located at the center of groove body；
Step 2: cleaning groove body cuts place, and so that groove body bottom is smooth in groove body bottom asphalt concrete layer；
Step 3: groove body surface and bituminous concrete surface smear epoxy resin in step 2；
If Step 4: presetting dried layer casing in groove body, every layer of described sleeve pipe includes several groups of casings along groove body length side
To evenly distributed, every group of described sleeve pipe includes two casings being oppositely arranged along groove body width, and every group of described sleeve pipe is led to
A slide-bar connection is crossed, the slide-bar is threaded through in two casings being oppositely arranged；
Step 5: fiber concrete is taken to fill groove body, and compacting so that the fiber concrete after compacting and bridge floor are neat repeatedly
It is flat.
Preferably, the groove body depth in step 1 is 8-10cm.
Preferably, step 4 middle sleeve is provided with three layers.
Preferably, the interlamellar spacing of casing described in step 4 is identical.
Preferably, the tail end connection of casing described in step 3 is on the supporting plate, the support plate is fitted in the side of groove body
On wall, the described sleeve pipe horizontal abutment of the bottom is on bituminous concrete.
The beneficial effects of the invention are as follows：The present invention by more than construction technology, to the secondary excavation of bridge floor and expansion joint with
And filling is repaired, and by service sleeve and slide-bar and fiberfill fibers concrete, greatly improved expansion joint concrete nearby
Pave and roll condition, can guarantee its compactness, reduce height difference caused by vehicle effect secondary compaction, and then be effectively improved bridge
Head jump vehicle situation；By service sleeve and slide-bar and fiberfill fibers concrete, the anti-of the neighbouring concrete in expansion joint is also strengthened
Tensile strength reduces the air shrinkage value of concrete, and effectively improving expansion joint, nearby concrete cracking, drying shrinkage happen, into
And it is effectively improved bumping at bridge-head situation.

Specific embodiment
With reference to embodiment, the invention will be further described：
A kind of bridge shrinking cracks jumping prevention construction method includes following steps：
Step 1: milling bridge floor and cutting the expansion joint 7 adjacent with bridge floor so that milling and the part cut form one
A groove body 1, the expansion joint 7 are located at the center of groove body 1, and 1 depth of groove body is 8-10cm.；
Step 2: cleaning groove body 1 cuts place, and in 2 layers of 1 bottom asphalt concrete of groove body so that 1 bottom of groove body
It is smooth；
Step 3: the 2 surface smear epoxy resin of 1 surface of groove body and bituminous concrete in step 2；
Step 4: being preset with three layers of casing 3 in groove body 1, the interlamellar spacing of every layer of casing is identical, and every layer of described sleeve pipe 3 is wrapped
It is evenly distributed along 1 length direction of groove body to include several groups of casings 3, every group of described sleeve pipe 3 includes setting along groove body width is opposite
Two casings put, every group of described sleeve pipe 3 are connected by a slide-bar 4, and the slide-bar 4 is threaded through two casings being oppositely arranged
It is interior；The tail end of its middle sleeve 3 is connected in support plate 6, and the support plate 6 is fitted on the side wall of groove body 1, the bottom it is described
3 horizontal abutment of casing is on bituminous concrete 2.
Step 5: fiber concrete 5 is taken to fill groove body 1, and compacting causes the fiber concrete 5 and bridge floor after compacting repeatedly
It flushes.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art without
Creative work is needed according to the present invention can to conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
