The technical solution of the utility model is: comprise sample bucket, suspension ring, lining rope, base plate and baffle plate, and described sample bucket is the cylindrical shell of both ends open, and the upper end of cylindrical shell connects suspension ring, lower end connecting bottom board; Described suspension ring connect lining rope, the central openings of described base plate and realize unidirectional to open or closed by the baffle plate being hinged on plate upper surface.
Such scheme can more preferably:
The side of described cylindrical shell is fixed with one or more balancing weight, can select suitable counterweight according to actual conditions.
Described cylindrical shell is the seamless steel pipe of long 110mm, wall thickness 5mm, external diameter 120mm; Described base plate is the steel plate of radius 61mm, thick 1mm; Described hole is the circular hole of radius 20mm; Described baffle plate is the round plate of radius 23mm; Described suspension ring are the arc-shaped ring body that Φ 6 reinforcing bar is made; Described lining rope adopts steel matter lining rope (lining rope Material Strength is higher not easily to be extended, and data scalar is accurate).Its middle cylinder body and base plate and suspension ring are welded to connect respectively.
The operating principle of above-mentioned sampler is as follows: before the complete conduit of pile foundation concreting is not extracted, and uses when the pile crown absolute altitude that plummet measures arrives theoretical elevation location.During use, sampler is sunk in boring, sink in process and read lining rope scale, accurately to fish for the slag specimen sample of desired area.After sampler arrives assigned address, upper and lower Fast Activities lining rope, makes sample bucket repeatedly move up and down fast in hole.Now bottom of device single-way switch when sampler sinks upwards activity open and make slag specimen enter in sample bucket, when above carrying sample bucket, single-way switch moves downward automatically in closed condition, prevents slag specimen from flowing out.After so activity has got slag specimen twice repeatedly, above carry lining rope and sample bucket has been proposed, in hole, slag specimen is poured out observation.For ensureing that institute's sample thief is representative, get some position slag specimen more.As slag specimen in sample bucket has a large amount of stone, cement, represent this pile crown place, position concrete continuous, stone is even, pile crown is up-to-standard.As in bucket without stone or stone less, represent this position pile crown concrete quality poor, laitance is too much, need continue to build part concrete to ensure pile foundation quality.
A kind of bored pile pile crown concrete sampler of the present utility model, compared with traditional pile crown sniffer and method, has following remarkable advantage:
(1) the utility model is compared with traditional survey tool, and technological principle is simple, and process operation is simple, processes former material and is easy to get, and practical simple to operate, low production cost, has higher use value.
(2) the utility model is compared with traditional plummet, not only can measure pile crown elevation of top, can visit simultaneously and get this position pile crown slag specimen, accurately can judge a top bit concrete quality according to slag specimen.Concrete can be avoided to surpass and to fill with the waste of material caused that exceeds standard, the construction cost increase that the later stage causes because abolishing, lifting, bury tall and big pile crown.Can avoid equally filling with not enough because pile crown is super, stake top off quality and cause the later stage deeply to cut a hole pile crown, formwork secondary builds the construction cost caused increases.
(3) the utility model is applicable to works limit comparatively extensively, is not only applicable to shallow-layer land pile driving construction, is more suitable for pile foundation construction on deep water.
In sum, a kind of bored pile pile crown concrete sampler of the present utility model, there is the advantages such as processing technology is simple, cost of production is low, wide accommodation, be applied to pile foundation construction, for constructor accurately judges that stake top concrete quality provides accurately, reliable foundation in early days, workmanship is played to mid-event control, accomplishes cost savings there is higher popularizing value.
