Have：Cast-in-place method diaphram wall, gravity type Reinforced Concrete Retaining Walls, cast-in-place cast-in-situ bored pile, steel sheet pile and concrete sheet-piling etc.,
Also traditional cemented rock, placed rockfill structure.The method that traditional supporting construction uses cast-in-site mostly, work of constructing
Phase length, work efficiency are low, construction costs is high, working procedure is complicated, and cemented rock, placed rockfill structure durability are poor, in gas
In the presence of being expanded with heat and contract with cold after temperature change, general 2-3 just occur block stone and concrete binding take off split, collapse phenomenon, structure
Quality is extremely unstable.And traditional sheet pile, seep water phenomenon generally existing for two joints, so, wanted applied to antiseepage function
Ask in high support engineering, U-board stake, the prefabricated sheet pile such as square lagging pile really can not thoroughly solve the problems, such as sealing.
Traditional water conservancy engineering other structures are contrasted, sheet-pile structure has that easy construction, durability are strong, cost performance is high, profile
A variety of advantages such as attractive in appearance, saving land used.It is now widely used for great rivers flood control and disaster reduction, the bank regulation of inland river lake and adds
Gu, the hydraulic engineering construction field such as port and pier shore protection, river embankment engineering.Sheet-pile structure is broadly divided into steel sheet pile and concrete slab
Stake.Steel sheet pile bending resistance anti-pressure ability is good, but it involves great expense, and perishable gets rusty.Then cost is lower for concrete sheet-piling, construction week
The advantages of phase is short.But the bending resistance stress performance of conventional concrete sheet pile is restricted with certain limitation by material and structure,
And after the completion of construction, sheet pile constitutes sealedly continuous wall construction, seriously hinders the infiltration of water, has cut off domatic and river course
Moisture, nutrition nutrient, the flowing of energy, are unfavorable for the aquatic environment ecological balance.
The content of the invention：

Rate is high, ensure that the globality and construction quality of structure, reduces construction costs, and engineering construction works well, and has earth-retaining and stops
Water function, alternative existing fender post wall construction.And the present patent application ensure that the hydraulic connections of water body and the bank soil body,
Be conducive to nutrition, the flowing of energy, and gear slope is played by shore protection component, keep the positive role of ecological environment balance.
Present invention can apply to river course waterway regulation works, Municipal Drainage Engineering, traffic roadbed support engineering, slope treatment
In engineering, take after special measures of preventing water, also can as provisional retaining structure be applied to base pit engineering and permanently under
Diaphragm wall and underground pipe gallery exterior wall etc..The present invention is simple in construction, construct convenient, economy, ecological, environmental protective.
One of technical problem that the present invention is solved is：The bending resistance stress performance of conventional concrete sheet pile is by material and knot
The restriction of structure has certain limitation, in the support engineering that antiseepage requires high, and two joint infiltration phenomenons are generally deposited
, it is impossible to really thoroughly solve the problems, such as sealing.And steel sheet pile its involve great expense, and perishable get rusty.The present invention solves above-mentioned
Problem.
The invention solves the problems that second technical problem be：The method that field of civil engineering uses cast-in-site, work of constructing
Phase length, work efficiency are low, construction costs is high, working procedure is complicated.Sheet pile constitutes sealed diaphragm wall knot in other existing hydraulic engineering
Structure, seriously hinders the infiltration of water, has cut off domatic and river course moisture, nutrition nutrient, the flowing of energy, has been unfavorable for aquatic environment
The ecological balance.Present invention addresses above mentioned problem.
