Abstract
The utility model relates to a steel pipe pile cofferdam structure, which comprises at least two rows of steel pipe piles, channel steels and I beams, wherein the inside of the steel pipe piles is filled with coarse sand; the two rows of steel pipe piles, the channel steels and the I beams are fixedly connected to form a stereo frame structure; the two rows of steel pipe piles are laterally connected by the channel steels; the steel pipe piles on the same side are longitudinally connected by the I beams; the inside of the frame structure is provided with moso bamboo sheets; the moso bamboo sheets are fixed along the inner edges of the steel pipe piles; the inside of the moso bamboo sheets is lined with geotechnical cloth; and the geotechnical cloth is sewn on the moso bamboo sheets by rebar binding wires. The steel pipe pile cofferdam structure disclosed by the utility model has the advantages of simple structure, short construction period and low construction cost.
Description
Technical field
The utility model relates to a kind of cofferdam structure, relates in particular to a kind of steel pipe pile cofferdam structure, belongs to the temporary works field in water conservancy (river course) engineering
.
Background technology
Cofferdam, littoral facies river mouth is mainly built based on silt matter, liquid riverbed, the main feature in this class cofferdam is that substrate is unstable and seat base condition is poor, build weir and run duration is subject to tidal effect larger simultaneously, build weir early stage muddy water water content large etc., due to understanding not and misoperation cause the weir of collapsing, topple and the case such as sidesway more.Di cofferdam, littoral facies river mouth generally has two types, and a kind of is to adopt the soil engineering bag mask, inside fills shale beach material, forms low water head earth dam dash one, and such cofferdam structure is simple, but, because section is large, the duration is longer, operating expenses is higher; The second is filling powder loam or shale beach material in the continuous steel sheet pile in steel sheet-pile cofferdam ， bis-roads, and such cofferdam section is less, and the duration is relatively short, but steel quantity consumption is large, and the amortization cost is high.Therefore, provide a kind of simple in structure, the cofferdam structure that the construction period is short and cost is low, steel quantity consumption is little is the target that those skilled in the art pursue.
The utility model content
Technical problem to be solved in the utility model is the deficiency for cofferdam structure in prior art, and a kind of steel pipe pile cofferdam structure is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of steel pipe pile cofferdam structure, comprise at least two row's steel pipe piles, channel-section steel and i iron, described steel pipe pile inside is marked with coarse sand and two row's steel pipe piles, channel-section steel and i iron are fixedly connected into three-dimensional frame construction, wherein between two row's steel pipe piles, by channel-section steel, laterally connect, between the steel pipe pile of homonymy, by i iron, vertically connect, described frame construction inboard is provided with bamboo plate and bamboo plate is fixed along the steel pipe pile inner edge, described bamboo plate liner geotextiles, geotextiles is tied up silk by reinforcing bar and is made on bamboo plate, described channel-section steel and i iron longitudinally are provided with multilayer, described bamboo plate order is from the bottom to top laid, laminate lower in upper slice, between two bamboo plates, overlap joint is no less than 5.0cm.
According to the technical solution of the utility model, steel pipe pile, channel-section steel and i iron are fixedly connected into to the cofferdam framework, this cofferdam structure is simple, and the construction period is short and to compare the steel sheet pile cofferdam structure steel quantity consumption little, and cost is low.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model embodiment;
The cross sectional representation that Fig. 2 is A-A direction shown in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
embodimenta kind of steel pipe pile cofferdam structure, comprise at least two row's steel pipe piles 1, channel-section steel 4 and i iron 3, described steel pipe pile 1 inside is marked with coarse sand and two row's steel pipe piles 1, channel-section steel 4 and i iron 3 are fixedly connected into three-dimensional frame construction, wherein 1 of two row's steel pipe pile laterally connects by channel-section steel 4, 1 of the steel pipe pile of homonymy vertically connects by i iron 3, described frame construction inboard is provided with bamboo plate 2 and bamboo plate 2 is fixed along steel pipe pile 1 inner edge, described bamboo plate 2 liner geotextiles, geotextiles is tied up silk by reinforcing bar and is made on bamboo plate 2, described channel-section steel 4 and i iron 3 longitudinally are provided with multilayer, described bamboo plate 2 order is from the bottom to top laid, laminate lower in upper slice, between two bamboo plates 2, overlap joint is no less than 5.0cm.
Specifically, at first steel pipe pile 1 is squeezed into to ground end 5m, at the interior injection coarse sand of steel pipe pile 1, doing the horizontal dimension guard beam with i iron 3 vertically connects the steel pipe pile of homonymy 1, doing the drawknot beam with channel-section steel 4 laterally connects two row's steel pipe piles 1, the three forms the frame construction in cofferdam, the cofferdam framework is after confirming reinforcing, with bamboo plate 2, along steel pipe pile 1 inner edge, fix, bamboo plate 2 order is from the bottom to top laid, and laminates lower in upper slice, and geotextiles is tied up to silk with reinforcing bar and make on bamboo plate 2, and then, with clay 5 fill frame inside, form the cofferdam entity.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
