Abstract
The invention relates to an auxiliary device used in underwater concreting in pile foundation engineering and in particularly relates to an underwater concreting sampler of a bored pile for carrying out sampling testing on an underwater concreting state. The underwater concreting sampler of the bored pile comprises a section of hanger rope, the lower end of the hanger rope is connected with a hanging beam, two arms of the hanging beam are connected with the cylinder wall at the upper end of a storage cylinder in a shape of a cylinder, an openable or closable valve is arranged at the bottom of the storage cylinder, the valve consists of two semi-circular door plates, a rotary shaft arranged on the diameter is arranged at the opening at the bottom of the storage cylinder, the two semi-circular door plates are both articulated to the rotary shaft, a stop pin is also arranged on the inner wall at the lower end of the storage cylinder, and the edges of the semi-circular door plates drop on the stop pin when the valve is closed. The underwater concreting sampler of the bored pile has a simple structure, is easy to process, is low in manufacture cost and is convenient to use; and with the adoption of the underwater concreting sampler of the bored pile, during construction, the storage cylinder is put into a pouring hole through the hanger rope, whether pouring is in place is simply judged by a sampling result of the storage cylinder without deep influence by a pile foundation, and the accurate position on the top surface of concrete can be exactly and intuitionally judged, so that quality accidents generated in pile foundation construction are avoided.
Description
Technical field
The present invention relates to the servicing unit that uses in a kind of pile foundation engineering underwater concreting, specifically is a kind of bored pile underwater concreting sampler that the underwater concreting state is carried out sampling and testing.
Background technology
Bearing capacity is big because bored pile foundation has, good stability, settling amount are little, receive working water level or groundwater table just to influence advantages such as less; And construction technology and technical development are ripe; Selectable construction machinery kind is more; And, be applied in the large bridge basis constantly to ultra dark, super-large diameter stake development.But bored pile is as concealed work, and the quality control difficulty is big, especially under water during concrete spouting; Concrete is positioned under the mud of hole all the time; Can't observe the concreting position, for judging the underwater concreting height, as the foundation of concrete perfusion dismounting conduit; Usually be employed in and fasten a plummet on the lining rope of length scale mark and put into the hole, the constructor relies on lining rope to be transferred to feel to judge the concreting degree of depth.The constructor's feel to control the concreting degree of depth owing to need to rely on; Therefore receive multiple factor affecting such as construction experience, on-site concrete quality, plummet weight, be difficult to accurately judge concrete accurate position, conduit takes place in work progress unavoidably buried underground and can't extract deeply or conduit pulls out problems such as sky; Cause great quality accidents such as broken pile; Not only brought hidden danger of quality to construction, it is bigger to have handled this type of problem stake difficulty simultaneously, especially to the ultra deep pile foundation of major diameter; Not only will spend than the large economy cost, the processing time is also longer simultaneously.For the generation of avoiding above problem also once the someone invented concrete sampler under water; But its processing and fabricating is more loaded down with trivial details; Inconvenient operation; Especially very inconvenience of operation when depth selection is dark needs back and forth spreading, removes guide rod, be unfavorable for drilled pile construction needs fast, completion is built in the short time construction requirement.
Summary of the invention
Technical problem to be solved by this invention is; Provide a kind of simple in structure, easy to operate; And when the drill-pouring pile underwater concrete pours into, not limited by the degree of depth, and can be accurately, rapidly, the bored pile underwater concreting sampler of visual control top of concrete height.
Bored pile underwater concreting sampler of the present invention includes one section lifting rope, and the lifting rope lower end is connected with hanging beam, and two arms of hanging beam are connected with a material storage tube cylindraceous upper end barrel, and the material storage tube bottom is provided with the valve that can open or close; Said valve is made up of two semicircular door-plates, and material storage tube bottom opening place is provided with the rotating shaft that is positioned on the diameter, and two semicircular door-plates all are hinged in the rotating shaft; Also be provided with backing pin on the inwall of material storage tube lower end, the edge of semicircle door-plate dropped on the backing pin when said valve was closed.
Said material storage tube lower end circumference is set to the less incision sword of wall thickness, so that in the incision concrete.
Said material storage tube middle part is provided with pin, is used for the open position of double circular door-plate to carry out spacing.
The present invention is simple in structure, handling ease, cost of manufacture are low, easy to use; Through lifting rope material storage tube is put into fill orifice in the work progress; Can judge to build whether put in place simply through the sampling result of material storage tube; It does not receive the pile foundation effect of depth, and can quick and precisely judge the accurate position of top of concrete intuitively, avoids taking place in the pile foundation construction quality accident.

Fig. 2 is a side of the present invention sectional structure sketch map.
The specific embodiment
As shown in the figure, this bored pile underwater concreting sampler includes one section lifting rope 1, and the lifting rope lower end is connected with hanging beam 2, and two arms of hanging beam are connected with material storage tube 3 upper end barrels cylindraceous, and material storage tube 3 bottoms are provided with the valve 4 that can open or close; Said valve is made up of two semicircular door-plates 41, and material storage tube bottom opening place is provided with 5, two the semicircular door-plates 41 of rotating shaft that are positioned on the diameter and all is hinged in the rotating shaft 5; Also be provided with backing pin 6 on the inwall of material storage tube lower end, the edge of semicircle door-plate 41 dropped on the backing pin 6 when valve 4 was closed.Material storage tube 3 lower end circumference are set to the less incision sword 7 of wall thickness, so that in the incision concrete.Material storage tube middle part is provided with pin 8, is used for the open position of double circular door-plate 41 to carry out spacing.
In work progress, discharge lifting rope 1 material storage tube 3 is put into the drilled pile hole, behind material storage tube contact concrete, utilize deadweight in being lowered into concrete; In sinking to process, concrete is pushed valve 4 open, and concrete gets in the material storage tube; Go up the lifting rope then; In the material storage tube uphill process, the concrete that enters in the material storage tube is depressed valve 4 under action of gravity, gets the material storage tube lower end and is closed; Smoothly concrete is taken out, can confirm concrete surface height accurately according to material situation that collects in the sampler and the lifting rope length of transferring then.
