Abstract

The utility model relates to the technical field of water conservancy construction cofferdam water stopping, in particular to a large-diameter round steel plate pile cofferdam device. The large-diameter round steel plate pile cofferdam device comprises a cofferdam arranged around a bearing table, and is characterized in that the cofferdam comprises a steel pipe pile layer which is arranged on the inner layer and used for locating and guiding, meshed Larsen steel plate pile layers which are arranged on the outer layer and used for separating water and blocking soil and a supporting structural layer between the steel pipe pile layer and the Larsen steel plate pile layers. The steel pipe pile layer comprises round steel pipes evenly distributed around the bearing table and connecting steel connected with the adjacent steel pipes, the supporting structural layer comprises base plates at the corresponding positions of the outer sides of the steel pipes and steel plate pile supports which are arranged on the outer sides of the base plates and connected with the adjacent base plates, and the Larsen steel plate pile layers are inserted and thrown into the soil through locating of the steel pipe pile layer and locating of the supporting structural layer. The large-diameter round steel plate pile cofferdam device is simple in structure, reasonable in design and convenient to mount, materials are saved, meanwhile, water pressure can be effectively decomposed, and compared with an existing cofferdam, the device is more economical, and the construction is more convenient.

Description

The round steel sheet-pile cofferdam device of major diameter
Technical field
The utility model relates to a kind of cofferdam device, is specifically related to the round steel sheet-pile cofferdam device of a kind of major diameter.
Background technology
The variation of existing China Assessment of Highway Bridge Structures form, cross a river Large Span Bridges is with cable stayed bridge, suspension bridge, steel arch bridge designs for main flow, for some special geology, as geological stratification is weak soil, silt, flour sand, fine sand, cement loess, gravelly soil, and it is very complicated to be the strong distribution geological stratification of bar, because of elevation at the bottom of cushion cap, geology, river level determines, some foundation ditches can not adopt builds the method construction that mud is inhaled in island supporting, determine and divide into steel sheet-pile cofferdam or steel jacket box vertical cut, because of the changeable complexity of geological stratification, the equilibrium of steel jacket box hanging integrated transfers that difficulty is large and cost is high, therefore for needs, adopting new equipment to take structure goes out stressed even, new technical scheme reasonable in design.
Utility model content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of round steel sheet-pile cofferdam device of major diameter of can be easy for installation, can effectively alleviating hydraulic pressure is provided.
For achieving the above object, the technical scheme of taking is:
The round steel sheet-pile cofferdam device of a kind of major diameter, comprise the cofferdam that is arranged on cushion cap surrounding, described cofferdam comprises the steel pipe pile layer for positioning and guiding that is positioned at internal layer, be positioned at the Larsen steel sheet pile layer of the outer field mutual interlock for water proof gear soil, and the supporting and protection structure layer between steel pipe pile layer and Larsen steel sheet pile layer, described steel pipe pile layer comprises the round steel pipe and the connection steel that is connected adjacent two steel pipes around cushion cap circumference uniform distribution, described supporting and protection structure layer comprises the backing plate that is arranged on correspondence position outside steel pipe and is arranged on backing plate outside and is connected adjacent two backing plate steel sheep pile supports, described Larsen steel sheet pile layer buries by the skin location inserted to play of the internal layer location of steel pipe pile layer and the steel sheep pile support of supporting and protection structure layer.
The adjacent two described angles that connect steel are 160 ° ~ 175 °.
Described cushion cap and the steel tube place spacing between circle is 2.5m ~ 4.5m.
Described connection steel and steel sheep pile support all adopt H shaped steel.
Adopt technique scheme, obtained beneficial effect is:
The utility model is simple in structure, reasonable in design, easy for installation, saves material, on the basis of existing mounting structure, carry out breakthrough innovation, thereby can effectively decompose hydraulic pressure, reduction engineering time and construction cost, greatly improved construction speed simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the local structure for amplifying schematic diagram of cofferdam device.
Sequence number in figure: 1 is that steel pipe pile layer, 2 is that Larsen steel sheet pile layer, 3 is that supporting and protection structure layer, 4 is that steel pipe, 5 is that backing plate, 7 is that steel sheep pile support, 8 is cushion cap for connecting steel, 6.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
Referring to Fig. 1, Fig. 2, the round steel sheet-pile cofferdam device of a kind of major diameter, comprise the cofferdam that is arranged on cushion cap 8 surroundings, described cofferdam comprises the steel pipe pile layer 1 for positioning and guiding that is positioned at internal layer, be positioned at the Larsen steel sheet pile layer 2 of the outer field mutual interlock for water proof gear soil, and the supporting and protection structure layer 3 between steel pipe pile layer 1 and Larsen steel sheet pile layer 2, described steel pipe pile layer 1 comprises the round steel pipe 4 and the connection steel 5 that is connected adjacent two steel pipes 4 around cushion cap 8 circumference uniform distributions, described supporting and protection structure layer 3 comprises the backing plate 6 that is arranged on steel pipe 4 outside correspondence positions and is arranged on backing plate 6 outsides and is connected adjacent two backing plate steel sheep pile supports 7, the skin location inserted to play of described Larsen steel sheet pile layer 2 location of the internal layer by steel pipe pile layer 1 and the steel sheep pile support 7 of supporting and protection structure layer 3 is buried, the adjacent two described angles that connect steel 5 are 160 ° ~ 175 °, spacing between described cushion cap 8 and steel pipe 4 place circles is 2.5m ~ 4.5m, described connection steel 5 and steel sheep pile support 7 all adopt H shaped steel.
The utility model is simple in structure, reasonable in design, easy for installation, saves material, on the basis of existing mounting structure, carry out breakthrough innovation, thereby can effectively decompose hydraulic pressure, reduction engineering time and construction cost, greatly improved construction speed simultaneously.
