Description
Technical field：
The utility model is related to pile foundation construction secondary pile hole cleaning sand filter under a kind of bridge water, specifically a kind of small filter sand
Expect device, is suitable for all kinds of bridge underwater pile secondary pile hole cleanings and constructs.
Background technology：
Engineering construction bridge pile foundation basis is more and more frequent using underwater gliders, and pile body is long, stake diameter is big, concrete
The features such as dosage is big, row's mud amount is big, the borehole cleaning time is long before filling concrete, hardly results in environmental requirement, especially mud
Discharge.By mud pit and the amount digging of circulatory pool deposit side, (side's amount of mud pit is the 3 of pile foundation concrete square amount under normal circumstances greatly
Times), and often orographic condition is restricted, and crossing bridge is more confined from that (crossing bridge pile foundation construction, mud emission utilize mud
Ship), these measures have natural disadvantage：Side's amount of mud pit (mud carrier) is enough big, but during borehole cleaning recycles the time compared with
It is long, the mud conditioning expense bigger in later stage.
Invention content：
To overcome the deficiencies of existing technologies, the purpose of this utility model is to provide pile foundation construction under a kind of bridge water is secondary
Borehole cleaning sand filter improves the pouring quality of concrete and overcomes the natural disadvantages such as big, the borehole cleaning time length of mud emission amount, has system
Make it is simple, of low cost, sturdy and durable, environmentally friendly, energy saving, save artificial, the features such as shortening the construction period.
The utility model solves technical problem and adopts the following technical scheme that：
Pile foundation construction secondary pile hole cleaning sand filter under a kind of bridge water：
It is integral type knot that the sand filter, which has the cone of the cylinder and lower part on hollow top, upper and lower part,
Structure is equipped with inlet pipe on the top of cylinder, and has grout outlet in the side radial communication of cylinder in an axial direction；
It is equipped with valve in the bottom of the cone.
Mud is entered the inner cavity of the cylinder and cone by the inlet pipe, is formed and is circled round in the circular cone intracoelomic cavity
Vortex, is flowed out by the grout outlet.
The internal diameter of the cylinder is equal with height, and the internal diameter of the inlet pipe and grout outlet is the 1/4 of cylinder inner diameter
To 1/5, and the height of cylinder is more than length of the length less than inlet pipe of grout outlet.
The height of the cone is 2 to 3 times of the height of cylinder.
The lowermost end of the cone has one section for cylinder, and the height of the cylinder is the 1/3 of cylinder height, described
Valve is mounted in the tube chamber of the cylinder.
The lumen diameter of the cylinder is the 1/6 to 1/7 of cylinder inner diameter.
Compared with the prior art, the beneficial effects of the utility model are embodied in：
Pile foundation construction secondary pile hole cleaning sand filter device under the utility model bridge water, its main purpose are to reduce mud
In sand content, ensure concrete filling process pile total quality.At this stage, engineering construction field is increasingly marked
Standardization, fining, scale, the requirement used worker and machinery also steps up, in cost-effective, environmental protection, saving
In the case of promoting quality, the overall situation of standardized construction, the perfusion of underwater concrete can be greatlyd improve using the equipment for the energy
Quality, at the same also can be improved production efficiency, save it is artificial, shorten the construction period, be cost-effective, environmental protection.
Its advantage also resides in：
1. making simple, of low cost, sturdy and durable；
2. to underwater concrete filling pile, secondary pile hole cleaning before filling concrete avoids the big problem of sand content, concrete
Pouring quality be greatly improved；
3. by sand filter circulating mud, sand factor is reduced, reduces the amount of water toward mud pit.
4. construction field is more demanding to live environmental protection, civilization at this stage, the utility model is conducive to environmental protection；
5. slush pump must be connected in this sand filter and be matched, make mud where come where, avoid toward in well
Add clear water to increase mud amount, also has larger benefit to environmental protection；
6. semiautomation operation can largely reduce artificial and energy cost, often shorten 1 day than tradition through calculating the duration
Conventional construction method reduces cost about 22*24*1 (electricity charge)+120 (labour cost)=648 yuan, and economic benefit is very notable.
Description of the drawings：
Fig. 1 is the elevation of the utility model；Fig. 2 is longitudinal cross-section diagram of Fig. 1；Fig. 3 is the B of Fig. 1 to sectional view.
Figure label：1 inlet pipe, 2 cylinders, 3 grout outlets, 4 cones, 5 valves.
Below by way of specific implementation mode, and in conjunction with attached drawing, the utility model is described in further detail.
Specific implementation mode：
Embodiment：In conjunction with attached drawing, pile foundation construction secondary pile hole cleaning sand filter under the bridge water of the present embodiment, structure is：
It is integral type knot that the sand filter, which has the cone 4 of the cylinder 2 and lower part on hollow top, upper and lower part,
Structure is equipped with inlet pipe 1 on the top of cylinder, and has grout outlet 3 in the side radial communication of cylinder in an axial direction；
It is equipped with valve 5 in the bottom of the cone.
The operation principle of this sand filter：
Slurry forms convolution vortex, the proportion due to sand than mud under the action of mud pump power in cone
Greatly, it can precipitate along the inner wall of cone under the action of power, finally be flowed out from valve port down automatically.
When use：Silently pipe is connect the inlet pipe suitable for reading 1 of cylinder with conduit, and the grout outlet 3 of side is connected to slush pump
It manages (threeway principle), which is prevented setting on easy tripod by connection after threading a pipe, and starts slush pump；It is dynamic in height
Mud forms vortex in sand filter cone 4 under the action of power, and sand is under the action of vortex, along the cone of sand filter
Inner wall is deposited to lower mouth, according to the size for the sand content in mud that experiment measures, determines the size that valve 5 is opened, sand is from valve
Mouth outflow.
In practice of construction operation, the speed to shake out can be adjusted by closing valve 5, a notable advantage is greatly
Reduce the size of mud sand content in well.
The sand filter device be steel construction weldment, when in use must with tripod support it is firm, perch or
Valve 5 is not less than 1 meter from reference plane；Filtering out the sand come must clear away in time, avoid pollution field operation face.
Simple, of low cost, sturdy and durable, environmentally friendly, energy saving, saving is artificial, shortens work with making for the sand filter
The features such as phase, can greatly improve the pouring quality of underwater concrete filling pile.
