Abstract
The invention discloses a composite material fold line-shaped plate connecting structure for permanent bank protection engineering, enclosure engineering and supporting engineering, which is formed by connecting a plurality of FRP fold line-shaped plates together; the transverse side edges of the FRP broken-line-shaped plate bodies are provided with lock catches, the lock catches of the adjacent FRP broken-line-shaped plate bodies are matched in shape and mutually locked or locked through a transverse connecting piece to form a whole; the FRP zigzag-shaped plate bodies which are vertically adjacent are cemented or connected with each other through a vertical connecting piece to form a whole. The invention solves the problems of low lock connection strength and poor durability of the prior enclosure sheet pile, such as large frictional resistance of a locking notch of a steel sheet pile, easy corrosion and deformation, larger gap between the locking notches after the construction of the concrete sheet pile and the prestressed concrete sheet pile and poor water-blocking performance.
Description
Technical field
The present invention relates to a kind of permanent bank protection work, go along with sb. to guard him the sheet pile structure in engineering, support engineering, be specifically related to a kind of for the composite material fold-line-shaped board connecting structure of engineering near water.
Background technology
Sheet pile structure with its prefabricated convenience, convenient, the advantage such as land occupation area is little of constructing at harbour, harbour, bridge, waters transformation and near water engineering be widely used.Existing sheet pile structure adopts timber sheet piling, steel sheet pile, reinforced concrete sheet pile, prestressed concrete plate stake etc. more.Wherein timber sheet piling snap close bonding strength is low, poor durability.Steel sheet pile is owing to connecting fore shaft easy-to-rust and distortion, cause steel sheet pile can not be smoothly along fore shaft and under, must carry out processing of rust removing or in fore shaft coating lubricating oil, thereby increase cost.Due to the internal corrosion of steel sheet pile fore shaft, fore shaft place frictional resistance is increased and large and sheet pile soil body resistance around, form unbalanced force, sheet pile is forwards tilted, increase the difficulty of construction.Concrete sheet-piling and prestressed concrete plate stake, because fore shaft form design difficulty, connected mode are single, cause in sheet pile construction and turn to difficulty; And sheet pile after construction between fore shaft gap larger, Watertightness can be poor.
By high-intensity fiber and resin compounded, formed, the composite material sheet pile of preparing by continuous production technology, has the advantages such as the low and life cycle cost of corrosion-resistant, high-strength light, maintenance cost is low, and successful Application is in the structure of newly-built and reconstruction.But it is lower in civil engineering, to apply maximum glass fiber compound material (GFRP) modulus of elasticity, if be designed to same cross section, the bending rigidity of GFRP sheet pile shore protection and the moment of flexure that can bear are much smaller than steel shore protection, and composite material sheet pile connects more difficult, current maximum length also only has tens meters, and this has limited the application of composite material in the higher deep water harbour of load level, navigation channel to a certain extent.
Summary of the invention
The object of the invention is for the connectivity problem that has now composite material sheet pile, propose that a kind of frictional resistance is little, easy construction, stagnant water effect excellent be connected reliable composite material fold-line-shaped board connecting structure,
The technical solution used in the present invention is: a kind of composite material fold-line-shaped board connecting structure, this structure is by multiple FRP(fibre reinforced composites) fold-line-shaped plate body links together;
The transverse sides of described FRP fold-line-shaped plate body is provided with snap close, the shape phase establishing of the snap close of adjacent FRP fold-line-shaped plate body, and mutually lock or lock by transverse connection, form an entirety;
By vertical connector, cementing or bolt interconnects vertical adjacent described FRP fold-line-shaped plate body, forms an entirety.
As preferably, two adjacent snap closes adopt two interlaced structures that are fastened and connected of parallel snap close connecting portion.
As preferably, two adjacent snap closes adopt two mutual sheathed engagement connection structures of cover shape snap close connecting portion.
As preferably, between two adjacent snap closes, be provided with parallel lock catch connector, and adopt two parallel snap close connecting portions respectively with the interlaced structure that is fastened and connected of parallel lock catch connector.
As preferably, between two adjacent snap closes, be provided with two-phase Corner Link, and adopt two snap close connecting portions respectively with the interlaced structure that is fastened and connected of two-phase Corner Link.
As preferably, between three adjacent snap closes, be provided with three-phase Corner Link, and adopt three snap close connecting portions respectively with the interlaced structure that is fastened and connected of three-phase Corner Link.
As preferably, described FRP fold-line-shaped plate body web or base plate are provided with FRP stiffening rib.
As preferably, described FRP fold-line-shaped plate body web and frange plate are provided with ribs, and stiffening rib can be designed to sandwich structure, and core can be cork wood, carbon fiber board or steel.
As preferably, described vertical connector height is 300～600mm.
As preferably, described vertical connector is H or Z-shaped connector, and material is FRP.
The present invention uses in space enclosing structure, and the horizontal connected mode of FRP fold-line-shaped sheet pile mainly contains 5 kinds, is respectively parallel snap close connection, the connection of parallel lock catch connector, the connection of cover type snap close, two-phase Corner Link and three-phase Corner Link.Wherein parallel snap close connects and the connected mode of parallel lock catch connector provides a plane for fold-line-shaped plate, can be for engineering.Near water, structure corner can adopt two-phase connector with three-phase Corner Link, fold-line-shaped plate to be connected, and adapts to engineering circuit.For the vertical connected mode of broken line plate, can adopt at the root of fold-line-shaped sheet pile is highly the vertical connector of 300～600mm, and fold-line-shaped sheet pile is inserted to vertical connector (composite material section bar) and by cementing or bolt, vertical connector is connected as a whole with upper and lower two boards stake.
Beneficial effect: the invention solves existing composite material sheet pile level to the problem of vertical connection, the requirement that composite material sheet pile can adaptation to the ground be turned to, vertically can realize reliable pile extension, by the application that promotes composite material at deep water, heavily loaded harbour or harbour simultaneously.
