Abstract
The utility model discloses a kind of quicksand formation construction pipe well points constructing structure, comprise punching and a well casing that an employing high pressure punch pattern obtains, the described punching degree of depth is greater than well casing length 300 ~ 500mm, diameter is 287mm, described well casing is embedded in this punching, coarse sand is embedded with between bottom the shaft bottom of described well casing and punching, and be embedded with filter pipe between described well casing outer wall and punching inwall, described filter pipe periphery is filled out and is provided with filtrate, and fills out between the well head of described well casing and punching and be provided with one deck clay; The utility model adopts and first digs deep hole at drifting sand layer and silty sand ground, on deep hole basis, bury the mode of well casing again underground, has carried out solid foundation, thus the work of drawing water can be carried out smoothly for next drawing water.
Description
Technical field
The utility model relates to a kind of building operations structure, particularly relates to a kind of quicksand formation construction pipe well points constructing structure.
Background technology
The littoral regional Construction bridge in the Yellow River has the particularity in its geographical position, it is drifting sand layer and silty sand ground that exploration geology data show a lot of location, be mingled with part of clay layer earth formation situation complicated and rare, and groundwater table height is also different, also there is very large difference in choosing of construction technology, sandy stratum meets water can produce phenomenon of caving in, in addition at the bottom of the bearing capacity of foundation soil of earth's surface, difficulty of construction is large, to safety, the reliability requirement harshness of construction overall plan, in other words preparative work before construction wants fully sturdy, and after implementing, the leeway of change and adjustment is less.Especially the project initial stage will get rid of the water content in soil layer, is not worth the good method used for reference at present.
Utility model content
The utility model is exactly for the problems referred to above, and propose a kind of quicksand formation construction pipe well points constructing structure, this structure can get rid of the water content in drifting sand layer and silty sand ground more easily, lays the first stone for building bridge.
For solving the problems of the technologies described above, a kind of quicksand formation construction pipe well points constructing structure that the utility model provides, comprise punching and a well casing that an employing high pressure punch pattern obtains, the described punching degree of depth is greater than well casing length 300 ~ 500mm, diameter is 287mm, described well casing is embedded in this punching, coarse sand is embedded with between bottom the shaft bottom of described well casing and punching, and be embedded with filter pipe between described well casing outer wall and punching inwall, described filter pipe periphery is filled out and is provided with filtrate, and fills out between the well head of described well casing and punching and be provided with one deck clay.
Further, the thickness of described filtrate is between 2-4mm.
Further, the soil thickness of described clay is more than 0.5 meter.
The utility model adopts and first digs deep hole at drifting sand layer and silty sand ground, on deep hole basis, bury the mode of well casing again underground, has carried out solid foundation, thus the work of drawing water can be carried out smoothly for next drawing water.
Accompanying drawing explanation
Shown in Fig. 1 is appearance assumption diagram of the present utility model.
Wherein: 1, punching; 2, well casing; 3, coarse sand; 4, filter pipe; 5, filtrate; 6, clay.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, pipe well points constructing structure is used in a kind of quicksand formation construction, comprise punching 1 and a well casing 2 that an employing high pressure punch pattern obtains, the degree of depth of this punching 1 is greater than well casing 1 length 300 ~ 500mm, diameter is 287mm, and well casing 2 is embedded in this punching 1, is embedded with coarse sand 3 between bottom the shaft bottom of well casing 2 and punching 1, and be embedded with filter pipe 4 between the inwall of the outer wall of well casing 2 and punching 1, this filter pipe 4 can make water be deposited to the bottom of well casing 2 better; Fill out at filter pipe 4 periphery and be provided with filtrate 5, and fill out between the well head of well casing 2 and punching 1 and be provided with one deck clay 6; And the thickness of filtrate 5 is between 2-4mm, the soil thickness of clay 6 is more than 0.5 meter.By arranging filtrate 5 and the clay 6 of above-mentioned thickness, can allow between well casing 2 and punching 1 more firm in combination, being convenient to carry out smoothly in ensuing engineering of drawing water.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
