Description
Technical field
The utility model relates to the steel sheet pile guard system in a kind of Tidal zone and fluctuation of water table district, belong to especially a kind of safeguard procedures and the construction method being applicable to steel sheet pile quaywall steel sheet pile fluctuation of water table district and Lang Jian district in harbour engineering anticorrosion technique field, the steel sheet pile being in marine environment can be protected reliably, improve the overall durability of such harbour.
Technical background
Steel sheet pile quaywall is one of the most frequently used dock structure form, and its main substructure is steel sheet pile, and the durability of steel sheet pile determines application life and the safety in utilization of harbour.The current anti-corrosion method for steel sheet pile mainly contains the combination of three class methods such as coating, sacrificial anode and impressed current and these three class methods.Wherein sacrificial anode and this two classes anti-corrosion method of impressed current can only for districts under water; Steel sheet pile coating antiseptic cannot realize all standing in addition, and because of the restriction of pitching pile construction technology, coating antiseptic cannot be carried out in snap close position.This means that the snap close position of fluctuation of water table district and Lang Jian district steel sheet pile becomes steel sheet pile corrosion-resistant blind area.Easily cause this region non-uniform corrosion, affect the overall durability of steel sheet pile quaywall.
Utility model content
In order to solve above-mentioned practical problem, overcome in prior art and cannot implement effective corrosion-resistant problem to fluctuation of water table district and Lang Jian district position steel sheet pile, there is provided a kind of simple and reasonable, easy installation and reliable a kind of Tidal zone and the steel sheet pile guard system in fluctuation of water table district.
To achieve these goals, the utility model have employed following technical scheme: the steel sheet pile guard system in a kind of Tidal zone and fluctuation of water table district, it has one and keeps the armor plate of a determining deviation with steel sheet pile external surface, armor plate offers some installing holes, run through in installing hole and have bolt, bolt to be positioned at inside and outside installing hole both sides respectively thread connection have inner position nut and outside fix nut, the position that steel sheet pile external surface corresponds to each installing hole is welded with hold-down nut, bolt thread is connected in hold-down nut and makes to protect the filling chamber forming anticorrosion packing material between deck plate and steel sheet pile external surface, bottom and the side in the filling chamber of anticorrosion packing material sealed by encapsulant, anticorrosion packing material is filled with in the filling chamber of anticorrosion packing material, anticorrosion packing material after solidification and the common integrant steel sheet pile guard system of armor plate.
Preferably, described armor plate is glass fiber reinforced plastic armor plate.
Described armor plate is shaped according to the external surface shape of steel sheet pile.
The thickness in the filling chamber of described anticorrosion packing material determined by the distance between inner position nut and hold-down nut.
The utility model overcomes the problem that steel sheet pile is difficult to install armor, by being drilled with a series of installing hole not affecting antiseptic effect on armor plate, and adopt welding manner that nut is fixed on steel sheet pile external surface in advance, to realize the object of installing armor on steel sheet pile, installation process causes damage to steel sheet pile itself hardly.Thus overcome traditional anti-corrosion method and cannot spatter steel sheet pile to fluctuation of water table district and wave; especially the effective etch-proof difficult problem at snap close position, Bound moisture inferior segment adopts coating or anti-corrosion method such as coating associating sacrificial anode, impressed current protection etc. can realize the general protection of steel sheet pile.The utility model is also considered in water, subaqueous construction operation limitation is large, need the labour intensity as far as possible reducing constructor, comprise minimizing weight, simplify installation steps, exempt machinery to coordinate as far as possible, the prefabricated job placement of the overwhelming majority is completed in glass fiber armor processing space, thus realizes implementing armor installation to steel plate pile under the condition without the need to building operation platform.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing and embodiment, the utility model is described in further detail.
As Fig. 1 ~ 5 are depicted as steel sheet pile guard system of the present utility model, it has the glass fiber armor plate 2 mating with steel sheet pile 1 outer surface profile and be drilled with equally spaced installing hole 9 in advance, run through in installing hole 9 and have bolt 3, bolt 3 to be positioned at inside and outside installing hole 9 both sides respectively thread connection have inner position nut 6 and outside fix nut 7.Said inner side refers to the side of glass fiber armor plate towards steel sheet pile 1 herein, and outside is then the side of steel sheet pile dorsad.The position that steel sheet pile 1 external surface corresponds to each installing hole is welded with hold-down nut 5, bolt 3 thread connection make to protect in hold-down nut 5 to keep constant between deck plate and steel sheet pile external surface distance to form the filling chamber of anticorrosion packing material, bottom and the side in the filling chamber of anticorrosion packing material sealed by encapsulant, anticorrosion packing material is filled with, the anticorrosion packing material after solidification and the common integrant steel sheet pile guard system of glass fiber armor plate in the filling chamber of anticorrosion packing material.
Anticorrosion packing material can adopt such as: underwater epoxy grouting agent or cement-based mortar or under water pea gravel concreten or polyurathamc etc., specifically can determine according to the situation of locality.
Steel sheet pile guard system of the present utility model can pass through to implement with step:
(1) steel sheet pile 1 protected as required and residing tidal situation thereof, design the protection domain of steel sheet pile armor, the filling thickness of anticorrosion packing material and the pitch requirements of installing hole;
(2) size of the steel sheet pile protected as required and appearance profile, make glass fiber armor plate 2;
(3) on glass fiber armor plate, series installation hole 9 is bored;
(4) hold-down nut 5 by diver's Underwater Welding at steel sheet pile 1 external surface, its position and spacing corresponding with the installing hole 9 on glass fiber armor plate 2.；
(5) screw rod 3 thread connection in hold-down nut 5;
(6) thread connection inner position nut 6 on screw rod, in inner position nut 6 precession screw rod 3, regulate the position of inner position nut 6 according to the construction thickness requirement of anticorrosion packing material 4, and ensure that the distance between inner position nut 6 and hold-down nut 5 is consistent;
(7) installing hole 9 of glass fiber armor plate 2 is socketed on screw rod 3; And fix outside fix nut 7 in the opposite side thread connection of glass fiber armor plate, make glass fiber protect the filling chamber forming anticorrosion packing material between deck plate and steel sheet pile 1 external surface;
(8) seal on the base in the filling chamber of anticorrosion packing material and side polyurethane seal filler strip 8;
(9) adopt the filling chamber of mode to anticorrosion packing material of machine perfusion or artificial to carry out pouring construction, after anticorrosion packing material 4 solidifies, form overall steel sheet pile armor guard system with armor plate.
General recommendations carries out overall steel sheet pile armor protection to steel sheet pile Lang Jian district and fluctuation of water table district, if condition restriction also only can carry out the steel sheet pile armor protection of local for snap close position, its construction method is identical with above-mentioned construction method.
