Abstract
The utility model relates to a pile foundation cleaning device for construction, in particular to a pile foundation hole cleaning and sand screening device which solves the problems that an existing pile foundation hole cleaning device wastes time and labor, and is poor in hole cleaning effect. The pile foundation hole cleaning and sand screening device comprises a mud pump, a sand screening barrel and a mud sump which is communicated with the upper portion of a pile hole. A mud inlet of the mud pump is communicated with the mud sump, a mud outlet of the mud pump is communicated and tangent with an inlet of the sand screening barrel, an outlet of the sand screening barrel is connected with a high-pressure hose, the other end of the high-pressure hose is located at the bottom of the pile hole, a sand discharge port is arranged at the bottom of the sand screening barrel, and a ball valve is arranged at the sand discharge port. The pile foundation hole cleaning and sand screening device is reasonable and reliable in structural design, saves a large number of human resources and material resources, shortens hole cleaning time, effectively improves hole cleaning quality, and greatly lowers cost; the pile foundation hole cleaning and sand screening device has the advantages of being simple in structure, and convenient to operate.
Description
Technical field
The utility model relates to construction and uses the pile foundation cleaning plant, is specially a kind of pile foundation hole cleaning filtering sand apparatus.
Background technology
In pile foundation construction, extremely important after the pore-forming of Shi Zhuan hole, clear hole is also a very crucial procedure, and clear hole quality directly has influence on the quality of next procedure underwater concrete perfusion, finally has influence on the quality of pile.
General artificial removing screenings, the way of manually dragging for sand of adopting.This method is consuming time longer, and the effect behind clear hole is very undesirable, and often the sand factor needs for a long time could be up to standard.This is because all embody with the form of sand containing the coarse granule in layer of sand, soil, rock dust etc. in stratum.Certainly, site condition can arrange sedimentation basin preferably, and this method effect is better, but is subject to the place restriction.In practice of construction, be often that construction period is shorter, construction drill is concentrated, narrow field.
Summary of the invention
The utility model exists and wastes time and energy and the problem of clear hole weak effect in order to solve existing pile foundation hole cleaning, and a kind of pile foundation hole cleaning filtering sand apparatus is provided.
The utility model is to adopt following technical scheme to realize: the pile foundation hole cleaning filtering sand apparatus, comprise slush pump, sand filtering barrel and the mud pit be communicated with stake top, hole, the stock inlet of slush pump is communicated with mud pit, the grout outlet of slush pump is communicated with the entrance of sand filtering barrel and is tangent, the outlet of sand filtering barrel is connected with the other end and is positioned at a high-pressure hose of bottom, hole, the bottom of sand filtering barrel is provided with sand removing hole, and the sand removing hole place is provided with ball valve.
While carrying out hole operation clearly, the mud of mud pit enters slush pump through stock inlet, under the pressurization of slush pump, after the sand filtering barrel entrance enters in sand filtering barrel, form the High Rotation Speed eddy current, under the effect of centrifugal force, sand grains in mud separates with mud, and under gravity and centrifugal force double action, sand grains is separated out downwards simultaneously, sand removing hole by the sand filtering barrel bottom is discharged, and reaches the purpose of slurry sand separation; Minute isolate the mud after sand, discharge circulation through the grout outlet at sand filtering barrel top and enter in a hole.Having overcome existing pile foundation hole cleaning exists and wastes time and energy and the problem of clear hole weak effect.
The utility model reasonable in design is reliable, has saved a large amount of manpower and materials, has shortened clear hole in the time of the time, has effectively improved the quality in clear hole, and cost significantly reduces, and has advantages of simple in structure, easy to operate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-slush pump, 2-sand filtering barrel, 3-stake hole, 4-mud pit, 5-high-pressure hose, 6-sand removing hole, 7-ball valve.
The specific embodiment
The pile foundation hole cleaning filtering sand apparatus, comprise slush pump 1, sand filtering barrel 2 and the mud pit 4 be communicated with stake 3 tops, hole, the stock inlet of slush pump 1 is communicated with mud pit 4, the grout outlet of slush pump 1 is communicated with the entrance of sand filtering barrel 2 and is tangent, the outlet of sand filtering barrel 2 is connected with the high-pressure hose 5 that the other end is positioned at 3 bottoms, a hole, the bottom of sand filtering barrel 2 is provided with sand removing hole 6, and sand removing hole 6 places are provided with ball valve 7.
In specific implementation process, slush pump 1 should keep the 2-3 degree to tilt with the pipe inclined angle of sand filtering barrel 2, make this pipeline axis parallel with sand filtering barrel 2 cross section tangent lines, and a side outer rim is close to sand filtering barrel 2 inwalls.
Should manually skim larger rock slag before use.Larger rock slag can accelerate to aggravate the wearing and tearing of sand filtering barrel, and easily stops up slag notch.
Go out the quantity of slag and pass through the ball valve Artificial Control with the speed of slagging tap, simultaneously will be in conjunction with the suitable moisturizing of mud loss amount.By the deslagging moisturizing, mud balance also can reduce simultaneously, so deslagging speed is unsuitable too fast while starting, and prevents the too fast reduction of mud balance, and slag sand larger in hole can not be entrusted out in time, causes sediment too much.
To often convert the position of the hole inner bottom part mouth of pipe during clear hole, guarantee that Di Ge position, hole can clean to.
