Description
Technical field
The present invention relates to geotechnical engineering and traffic engineering technical field, specially a kind of highway culvert sap sealing protective layer
Structure.
Background technique
The type of seepage failure mainly has stream soil, piping, contact to flow soil and four kinds of contact scour.Single soil layer is mainly sent out
Raw stream soil and failure by piping, and contact stream soil and contact scour occur mainly at the contact surface of two kinds of soil layers.It is traversed having
In the highway embankment in culvert or tunnel, the effects of due to rainfall infiltration, the infiltration on the embankment soil body and culvert contact surface will cause
It destroys thoroughly, brings the destruction of embankment, it is therefore necessary to carry out the seepage control measure of contact surface；And after lower consolidation pressure gradually dissipates,
The moisture being discharged in embankment as early as possible is needed again, prevents the bad soil expansion filled in embankment from deforming, sealing impervious barrier meeting again at this time
As the obstacle for hindering moisture discharge.Mostly use waterproof material or setting drainage channel unilaterally to realize antiseepage in existing design
With drainage effect, but working procedure is more and drainage channel blocking can often occur and hidden dangers in project occur；Or only consider that waterproof carries out
Engineering design is unreasonable in this way.Therefore the present invention considers to propose a kind of highway culvert sap sealing protective layer structure and its system
Make method, to overcome the above problem, and can realize convenient and quick construction, and effectively realize the antiseepage and draining of highway culvert, mentions
The safety of high engineering design.

Preferably, sap Expandable strip is semi-cylindrical elongate configuration made of water-absorbing resins material.Semi-cylindrical strip knot
Structure is conveniently pasted on permeability flexible coating layer.
Preferably, the material of the permeable shell of rigidity is resin.
Single layer sap expands pearl plate and bilayer sap Expandable strip plate construction, may be incorporated for the bridges and culverts tunnel for crossing highway
In ectonexine sealing layer fabrication, using the physical characteristic of sap resin material water swelling dehydration drying shrinkage, it is adaptively adjusted
Water Transport between highway embankment and internal culvert.When there is large quantity of moisture to carry out seepage failure, in sealing protective layer material
Sap expanding material can water swelling, air-and water-permeable channel enclosed is got up, one layer of sealing layer is formed, prevents seepage failure；When
When prolonged drought, sap expanding material dehydration shrinkage, air-and water-permeable channel is opened, and small moisture can also pass through, so that public
Road ground inner ventilation is dry, guarantees that embankment is under good working order.The present invention is used in the sealing antiseepage of highway culvert
In engineering, simple process, it is convenient to be laid with, can be with rapid construction, and water-stagnating effect is good, belongs to the technologies such as geotechnical engineering and traffic engineering
Field.
The beneficial effects of the present invention are:
The present invention is used in highway culvert or crosses in the waterproof leak-stopping engineering in channel, can prevent the stream of the highway subgrade soil body
It is destroyed caused by mistake.It is built in engineering in highway culvert, backfills in layer and bury the sealing protective layer material, highway culvert is wrapped up
Get up.When there is large quantity of moisture to carry out seepage failure, sap expansion pearl or Expandable strip in sealing protective layer material can absorb water swollen
It is swollen, air-and water-permeable channel enclosed is got up, one layer of sealing layer is formed, prevents seepage failure；When prolonged drought, sap is swollen
Swollen pearl or Expandable strip dehydration shrinkage, air-and water-permeable channel are opened, and small moisture can also pass through, so that highway foundation inner ventilation
It is dry, guarantee that embankment is under good working order, the bed course for the construction of highway culvert sealing layer uses, and can take into account sealing
With it is ventilative.
The present invention is used in the sealing seepage control project of highway culvert, simple process, and it is convenient to be laid with, can be with rapid construction, only
Water effect is good, during drying and watering cycle, quasi- intelligent wet concentration of crossing may be implemented and select.
