Description
Technical field
The present invention relates to a kind of highway bridge maintenance and repair technologies, more particularly, to a kind of bridge pavement repairing construction skill
Art.
Background technology
With flourishing for China's economy and being constantly progressive for society, highway bridge is increasing to the effect of people,
All pay much attention to highway bridge construction in all parts of the country.Highway bridge not only becomes the main artery for linking up north and south economy, more can be one
Determine to promote the development of economy in degree.
Currently, China's highway is in fast-developing period, the increase with highway mileage and usage time
Extend, road maintenance engineering amount is also increasing.Maintenance project is generally divided into specific aim maintenance and preventive maintenance, and specific aim is supported
Shield refers to being taken appropriate measures according to Damage Types when road surface is destroyed, and improves the performance on road surface.It is preventative to support
Shield refers to implementing the technologies such as micro-surface area, ultra-thin wearing layer, mist envelope, the cementation of fissures when bituminous pavement property is still in shape and arranging
It applies road pavement and implements protectiveness maintenance, improve the function status on road surface under the premise of not increasing structural-load-carrying capacity, to prevent
The development of small disease delays serious destruction.
For highway since design speed per hour is high, the sedimentation and deformation and stability requirement to highway are high.Bridgehead by Blastig is uneven
The phenomenon that sedimentation, will produce prodigious influence to the life security of passing vehicle and pedestrian, and only take appropriate measures progress
Control, just can guarantee the quality on road surface.
Bridgehead by Blastig differential settlement causes transition slab at bridge head to come to nothing and then forms bumping at bridge-head, and bumping at bridge-head is universal and multiple
Miscellaneous problem, it is all that it is related to Embankment Subsidence, back filling behind abutment, abutment type, seam, transition slab at bridge head, road surface and construction method etc.
It is multifactor.The immediate cause that transition slab at bridge head comes to nothing is the settlement difference of abutment and roadbed.Abutment is rigid structures, its underpart one
As have a pile foundation, thus the deformation and sedimentation of abutment are very small, and roadbed and ground are flexible, have under load action compared with
Big plastic deformation, so the settling ratio abutment of Bridgehead by Blastig is big, the relative settlement both to cause.Once longitudinal poor
Different sedimentation is big, will cause road surface transverse crack, and running car is caused to slow down, jolt, shake, jump the problems such as vehicle, influences driving and relaxes
Adaptive, safety reduce running speed, increase the operation cost of vehicle and highway itself.
High polymer grouting technology has achieved in the rapid-maintenance of the infrastructure such as road, airfield runway and bumping at bridge-head
Prodigious success.Since high polymer has following features：（1）Density is small, ungauged regions, and the additional stress generated after repair is small；（2）
Speed of application is fast, and without maintenance, the influence to traffic is smaller；（3) material volume expands rapidly when reacting, can be having generated
Settlement difference narrow down to most preferably；（4）Slip casting aperture is small, is influenced on former hazard to bridge's pier globality small；（5）Infiltration coefficient is small, material
Expect that water resistance is good, and durability is good, pollution-free.So compared with traditional cement injection technology, with very big
Advantage has higher promotional value at home in the processing of bumping at bridge-head.After Bridgehead by Blastig uses high polymer grouting, board bottom is de-
Empty position is efficiently filled, and can effectively solve the problem that attachment strap absolute altitude, reaches equal with abutment, to realize adding for the soil body
Gu effect, while the position come to nothing in road surface structare layer, crack are filled, moisture is closed, the bearing capacity of pavement structure is promoted.
Since high polymer volume expansion during the reaction prevents high polymer in the prior art in order to control slip casting process
It is lifted road surface, the height change for monitoring road surface by laser level is usually needed during slip casting, when there is ground fine motion
Or grouting port slurry stops slip casting when emerging；But monitoring process is complicated, can not accurately control grouting amount, and occur ground
When face height change or slurry are emerged, may slip casting it is excessive, cause road surface to continue to be lifted.
Invention content
The present invention provides a kind of bridge pavement repairing construction technology, can be in high polymer grouting repair process, accurately
The grouting amount for determining high polymer avoids high polymer grouting excessively caused road surface lifting.
As one aspect of the present invention, bridge pavement method for repairing and constructing is provided, is included the following steps：（1）Pass through profit
Detections of radar is carried out to transition slab at bridge head section with Ground Penetrating Radar, determines region of coming to nothing；（2）Coming to nothing, slip casting is arranged in regional location
Hole；（3）It excavates and blocks spillage position of seriously coming to nothing under attachment strap both sides and abutment with concrete after roadbed side slope；（4）Pass through slip casting
Implement the first slip casting of high polymer to the region of coming to nothing in hole；（5）After the high polymer solidification of the first slip casting of the high polymer, pass through
The injected hole is to the region water filling of coming to nothing；（6）The water of the water filling is detected by flow sensing equipment；（7）When described
Injected hole has water body to emerge road surface, records the water of flow sensing equipment detection at this time；（8）It is examined according to the flow sensing equipment
The water of survey implements the second slip casting of high polymer by the injected hole to the region of coming to nothing；（9）Filling restores roadbed side slope.
Preferably, further include step（10）Injected hole concrete and pitch cold-repairing material are backfilled, road surface is restored.
Preferably, the step（2）Described in region of coming to nothing multiple injected holes are set, form slip casting hole array.
Preferably, the step（8）In, the water of flow sensing equipment described in the high polymer volume ratio of second slip casting
Low 5% ~ 10%.
Preferably, the step（4）In, first slip casting is used to form watertight area in the sections bottom that comes to nothing.
Preferably, the high polymer includes polyurethane material.
Preferably, the step（8）In, when the high polymer of the second slip casting cures, by step（5）Water filling discharge.
Preferably, the step（8）In, slip casting is carried out by the part injected hole of slip casting hole array.
