Description
Technical field
The invention belongs to dam construction seepage damage repair technical field, and in particular to one kind utilizes the emergent envelope of melted paraffin
The method and apparatus in the stifled underwater seepage crack of dykes and dams.
Background technology
Dam leakage is an important stage of flood season flood disaster risk, and emergent closure antiseep is turned off dam break and broken down disaster
The crucial behave of chain, but the emergent closure in the underwater seepage crack of dykes and dams still lacks fast and effectively technical measures.It is current underwater
The repairing in crack, frequently with technology be：（1）The dewatering method of sinking.Reducing water level is exposed crack, then using grouting method or
Surface sealing method mends a split.But the dewatering method of sinking can not meet emergent demand during flood, and dropped in river, reservoir
Low water level builds cofferdam, and cost is high.In many cases, water level can not be also reduced to below the position of crack.（2）Water
Lower concrete capable of not dispersing repairs underwater crack method.By with the also not concrete of dispersive property under water, crack location is poured into,
Treat concrete setting hardening and realize the closing and reparation of fracture.The limitation that this method is implemented is at following 2 points：First, water
During lower casting concrete, it is difficult to ensure that concrete is persistently solidified until hardening in crack location, often rushed by the current at crack
Walk, when especially crack is located at dykes and dams domatic middle and upper part, repaired using non-dispersible underwater concrete method particularly difficult；Second, it is
Making using early strong technology, non-dispersible underwater concrete setting and hardening to design strength also at least needs even a couple of days a few hours,
It is difficult to the needs for meeting emergent repairing.（3）Geotextiles cladding process.The method is typically from dykes and dams top down along domatic laying geotechnique
Cloth, until geotextiles are covered at crack, so as to realize that the closing of fracture blocks.The fixing point of geotextiles is located at the top of dykes and dams
Portion.This method is limited in that at following 2 points, first, in order to which geotextile laying is smooth, it is necessary to crack location will be arrived at the top of dykes and dams
Whole domatic debris weeds are cleared up, it is ensured that slope leveling.Cleaning work amount is big, and difficulty is also big.Two be due to geotextiles
General density ratio water is low, is easily disturbed during laying by current, causes out-of-flatness, forms leak paths.
The content of the invention
