Abstract

The utility model relates to an underwater concrete sampler used for judging whether the top of a bored pile achieves an elevation position. The underwater concrete sampler is characterized by comprising a storage barrel with two ends equipped with openings, wherein a guide rod is connected to the upper end of the storage barrel through a connecting block, two fixing plates are arranged on two sides of a position inside the storage barrel approaching the lower end thereof, two opposite moving plates are respectively hinged at a position with height equal to that of each fixing plate inside the storage barrel, supporting blocks for supporting the moving plates are arranged on an inner lateral wall of the storage barrel equipped with the moving plates, and a limit rod is arranged on the lateral wall of the storage barrel at the rear of the moving plates. The underwater concrete sampler is simple in structure, low in manufacturing cost and convenient in operation, can conveniently and accurately sample at a designed elevation position of an underwater concrete cast-in place pile, and judges whether an underwater cast-in place concrete surface achieves the designed elevation position or not, thereby reducing concrete waste and labor cost waste caused by over grouting, reducing construction cost and accelerating construction progress.

Description

Concrete sampler under water

Technical field

The utility model relates to the sampler in a kind of building foundation engineering, especially relates to a kind ofly being used to judge whether the stake top of bored pile reaches the sampler of concrete under water of absolute altitude position.

Background technology

Concrete drilling bored concrete pile is because of advantage such as its bearing capacity height, compliance be strong, become engineering piles commonly used in the domestic and international building, but the stake top mark high position of bored pile often is positioned at the position of following 5～6 meters even 10 meters of terrace face, because the terrace face all is a mud, naked eyes can't judge at all whether the degree of depth of concrete perfusion face reaches design elevation.The constructor adopts probing hammer usually even measures the degree of depth of concrete surface when pouring into the bamboo bar, this mode judges with constructor's experience and feel whether concrete surface reaches design elevation entirely, therefore error is very big, if the concrete of cast is measured inadequately, castinplace pile does not reach design elevation, need pile extension behind the foundation excavation, may influence the supporting capacity of perfusion pile body, and increase labor cost and construction cost; If the fluid concrete amount is too much, castinplace pile surpasses design elevation, also will require great effort to knock out above design elevation castinplace pile partly behind foundation excavation, not only wastes a large amount of concrete, equally also increases labor cost, thereby causes the rising of construction cost.

The utility model content

The applicant is at above-mentioned problem, carried out research and improved, and can accurately judge the sampler of concrete under water of the concrete perfusion face degree of depth when a kind of bored pile underwater concreting is provided, thereby reduce construction cost.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of sampler of concrete under water, the material storage tube that comprises both ends open, guide rod is connected the upper end of material storage tube by contiguous block, two fixed heads are arranged on the interior both sides near lower end of material storage tube, two portable plates of splitting are hinged in the material storage tube respectively and the fixed head equal-height position, portable plate is split the inside wall that is in material storage tube and is provided with the back-up block that supports portable plate, and the material storage tube sidewall behind the portable plate is provided with gag lever post.

Further:

Described guide rod comprises location guide and a plurality of lengthening guide rod for dividing section connection structure, and location guide is connected the upper end of material storage tube by contiguous block, and the lengthening guide rod through threaded is connected and fixed guide rod, and is end to end by screw thread between the lengthening guide rod.

Technique effect of the present utility model is:

The disclosed a kind of sampler of concrete under water of the utility model, simple in structure, low cost of manufacture, easy to operate, can be easily and accurately cast-in-place concrete pile design elevation place sampling under water, and judge whether the underwater concreting face has reached design elevation, reduce that the concrete that causes because of super filling is wasted and the waste of labor cost, reduce construction cost, accelerating construction progress.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1, 2, 3, the material storage tube 1 that comprises both ends open of the present utility model, guide rod 3 is welded on the upper end of material storage tube 1 by contiguous block 2, two fixed heads 5 are welded on the both sides of material storage tube 1 near lower end, that is to say, two fixed heads 5 are arranged in the material storage tube 1, from the following lower end of material storage tube 1 certain distance are arranged, and can make during use that material is easier to be entered in the material storage tube 1.Two portable plates of splitting 8 are hinged on respectively in the material storage tube 1 and fixed head 5 equal-height positions by bearing pin 7, and in the present embodiment, the bearing pin 7 on the portable plate 8 is inserted in the screw 9 on the material storage tube 1.Portable plate 8 is split and is welded with the back-up block 6 that supports portable plate 8 on the inside wall that is in material storage tube 1, and back-up block 6 is used to prevent portable plate 8 reversals of the natural order of things.Material storage tube 1 sidewall behind the portable plate 8 is provided with gag lever post 4, and gag lever post 4 is used for the corner amplitude of restraint plate 8 less than 90 degree (Fig. 1 is with the TP extreme position), portable plate 8 homings when being beneficial to promote, and the material that prevents to take a sample runs off in lifting process.Guide rod 3 is for dividing section connection structure, comprise location guide 301 and a plurality of lengthening guide rod 302, location guide 301 is welded on the upper end of material storage tube 1 by contiguous block 2, lengthening guide rod 302 is by the location guide 301 that is threaded, end to end between lengthening guide rod 302 and the lengthening guide rod 302 by screw thread, by increasing lengthening guide rod 302, make the length that guide rod 3 is lengthened to be needed.Each lengthening guide rod 302 can be made into fixing length, as 1 meter, so that determine the depth selection of whole sampler.

In use, make guide rod 3 lengthenings with lengthening guide rod 302, make sampler can reach the design elevation place of underwater concreting face, the operator hands guide rod, insert straight down in the stake hole, down in the slotting process, material will be pushed two portable plates 8 open, and discharge from the gap of material storage tube 1 upper end, up to reaching concrete surface design elevation place, the material at design elevation place will be pushed two portable plates 8 open, enter material storage tube 1, and on two fixed heads 5, pile up, at this moment guide rod is mentioned together with whole sampler, all will retain the material at this absolute altitude place on portable plate 8 and the fixed head 5, the operator can judge whether concrete reaches design elevation under water according to taking out the material situation.
