Description
Technical field
The utility model relates to the prefabricated sheet pile of a kind of steel concrete variable cross-section buttress type, belongs to the engineering fields such as municipal administration, water transport, port boat, is applicable to the sheet pile bank protection work in river course, navigation channel etc.
Technical background
Generally need the bank section place that the quilts such as (river) bank, seashore, loke shore wash away in the river that shore protection is set, to improve flood control safety and bunding stability.The form of structure of shore protection can be divided into the form of vertical type, ramp type or ramp type and vertical type combination, its type selecting should be determined according to composite factors such as river and river (sea) bank characteristic, construction land, shipping, constructional materials and execution conditions, consider in addition and suit measures to local conditions, the factor of the aspect such as gather materials on the spot, a lot of form of structure have appearred in engineering practice, such as the placed rockfill bank protection, cemented rock bank protection, concrete precast block bank protection etc.
Shore protection type commonly used has sloping formula shore protection, gravity revetment, sheet pile and pile foundation support table shore protection, longitudinal dike and short spur dike shore protection etc.Present widely used gravity revetment should adopt at ground preferably, when relatively poor ground adopts, must carry out ground stabilization and process, and should structurally take adequate measures.The buttress type soil-baffling structure obtains comparatively extensive use in engineering practice, main feature is simple structure, easy construction, wall body section is less, sole mass is light, can bring into play preferably the strength character of material, can adapt to the lower ground of bearing capacity, the buttress type structure is used for bank protection work also have preferably technical economic benefit.
Build harbour, harbour, important shore protection etc. at soft foundation, should adopt sheet pile formula shore protection.Sheet pile can be divided into timber sheet piling, reinforced concrete sheet pile and steel sheet pile 3 classes by material, the intensity of timber sheet piling is low, poor durability, wood consumption are large, now seldom adopt, steel sheet pile has the advantages such as quality is light, intensity is high, snap close is tight, sealing is good, easy construction, but the steel sheet pile cost is higher, easy-to-rust, need take rust preventing.Good endurance, the steel using amount of reinforced concrete sheet pile is few, cost is low, uses more in bank protection structure and sheet-pile wharf structure.Reinforced concrete sheet pile often adopts digging machine etc. to be equipped with hydraulic vibration driver and anchor clamps, clamps the sheet pile top to squeeze in the ground, and pile crown easily is caught broken by anchor clamps during construction, and verticality control is relatively poor.
In sum, the reinforced concrete sheet pile shore protection under suitable geological conditions and engineering background, has preferably technical economic benefit as a kind of shore protection form commonly used; And present monolithic rectangle reinforced concrete sheet piles that adopt more, material usage is large, construction difficulty comparatively under some geological conditions, and pile crown easily is caught broken by anchor clamps when setting construction, also exist stagnant water effect poor, with the problems such as the superstructure switching performance is poor.
Summary of the invention
The purpose of this utility model is to utilize the advantage of buttress type soil-baffling structure, overcome present reinforced concrete sheet pile pile sinking difficulty, pile crown easily by anchor clamps be caught broken, stagnant water effect is poor, with the problems such as the superstructure switching performance is poor; Invent a kind of material usage economize, cheap, be convenient to set construction, and the superstructure connectivity is good, the prefabricated sheet pile of steel concrete variable cross-section buttress type of good integrity.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
The prefabricated sheet pile of a kind of steel concrete variable cross-section buttress type is characterized in that comprising the superposed monolithic rectangular panel that connects as one and the separate type rectangular panel that is positioned at the bottom, and floor vertically is set on the monolithic rectangular panel; The top that monolithic rectangular panel two side ends arranges respectively semicircle protruding tongue and groove and semicircle recessed tongue and groove, two side is symmetrical arranged the anchor clamps steel panel, and at each anchor clamps steel panel lateral surface 2 above level connection joint reinforcing bars is set; Monolithic rectangular panel top also arranges gutter;
Separate type rectangular panel bottom arranges inverted trapezoidal stake end cutting edge; Vertical interval between separate type rectangular panel two medial surfaces equals the width of floor.
Floor is the chamfer triangle, and the vertical straight arm of angle that is connected with the monolithic rectangular panel and monolithic rectangular panel are with long, and end face flushes with monolithic rectangular panel end face, and two vertical lateral surfaces and separate type rectangular panel two vertical medial surfaces are at grade.
The prefabricated sheet pile of aforesaid a kind of steel concrete variable cross-section buttress type is characterized in that gutter is arranged on more than the ordinary water level after setting, quantity is more than 1 or one, and tilts laterally with 5 ~ 10 °, and the side end that pulls in to shore arranges the anti-filter geotextiles;
The prefabricated sheet pile of aforesaid a kind of steel concrete variable cross-section buttress type is characterized in that the separate type rectangular panel is identical with monolithic rectangular panel thickness, and width is the 1/8-1/4 of monolithic rectangular panel width, and length is 1/4 ~ 1/2 of prefabricated sheet pile pile body length.
The structure that the utility model relates to has following effect and advantage:
(1) top is the monolithic rectangular panel, the bottom is the separate type rectangular panel, both whole equal thickness settings, and in separate type rectangular panel end the inverted trapezoidal cutting edge is set, simultaneously floor employing plane is the chamfer triangular structure, can significantly save material, when reducing construction costs, the penetration resistance of stake is little, is convenient to the construction that sets of stake.
(2) setting of anchor clamps steel panel, when having overcome pile crown and easily be caught broken problem by anchor clamps, be convenient to a setting of top level connection joint reinforcing bar, the setting of level connection joint reinforcing bar can improve stake and the switching performance of superstructure, makes bank protection structure have good globality and cooperative bearing performance.
(3) setting of the gutter side underground water that can in time sheet pile be pulled in to shore is discharged, and reduces the lateral earth pressure of sheet pile, and the simultaneously gutter setting of side end anti-filter geotextiles of pulling in to shore can prevent sheet pile the pull in to shore seepage of side filler and the silting of gutter.
