Abstract
The utility model discloses a detecting device for concrete at the top of a drilled pile. The detecting device is characterized by being provided with a steel tube on which a length scale ruler is arranged, wherein the front end of the steel tube is fixedly provided with a slag fishing bucket and the slag fishing bucket takes a steel bar net piece as a bucket wall. With the detecting device, the height of the concrete pouring head in concrete pouring is detected, pouring exceeding or insufficient pouring is avoided, and therefore the construction progress is ensured.
Description
Technical field
The utility model relates to a kind of bored piles top concrete Height control testing tool.
Background technology
Fig. 1 a and Fig. 1 b are depicted as a kind of perfusion pile-formation process of drilled pile; Be that conduit 1 vertically is inserted into apart from 2 about 40cm places, bottom, stake hole; Concrete pours in the hole from conduit 1 gradually, and the mud extruding is discharged from the top, hole, when layer of concrete 3 constantly is increased to top of concrete 4 arrival design altitudes; Because extruding, mud layer 5 concentration that are positioned on the top of concrete are bigger.How passing through the height that mud layer 5 accurately records top of concrete 4 is to guarantee the concrete ultra necessity of irritating or owing to irritate that do not take place.
Such as; It is domestic to be positioned at Weinan City Heyang County, Shaanxi Province to the west of the construction 11# mark the Yellow River before the Line for Passenger Transportation station, China domestic big western railway road, and water level is higher, complicated geology; Be stream plasticity sand; For guaranteeing drilled pile construction pile crown concrete quality, design is carried out the ultra 1m that irritates of pile crown again manual work and is abolished during concrete spouting behind excavation of foundation pit.This project pile foundation degree of depth is big, and maximum effective length is 92m, hole depth 102m, and the stake apex distance is bigger from the casing apical side height, generally more than 5m, is 9m to the maximum.Adopt the perfusion pile-formation process; When top of concrete arrives design altitude, the mud layer of 9m thickness is then arranged in the hole approximately, and concentration is bigger; Adopt conventional measuring method because lining rope is too soft; Can't pass through mud layer, thus energy measurement top of concrete height not, so cause ultra irritate or owe to irritate all can influence programming.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of bored piles top concrete appliance is provided, be used to pour into pile-formation process can pass through mud layer accurately examine the top of concrete height.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model bored piles top concrete appliance is that a steel pipe that has the length graduated scale is set, and fixedly installs a slag bucket at the front end of said steel pipe, and said slag bucket is to be headwall with the reinforced mesh.
In pile foundation concrete spouting process, when treating concrete, utilize steel pipe to pass through the mud layer of irritating a top approximately apart from design altitude 1~2m, salvage with the slag bucket of steel pipe front end and irritate head position concrete, and detect filling head height degree with this.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model makes the concrete filling head height degree in the pile foundation concrete spouting process be able to detect, and avoids the ultra filling of irritating or owe, the assurance construction speed.
2, the utility model is simple in structure, few with; Its testing process is easy to operate, easy to implement.
Description of drawings
Fig. 1 a is a perfusion initial state sketch map in the drilled pile perfusion formation of pile;
Fig. 1 b irritates the head height degree in the drilled pile perfusion formation of pile to reach the design altitude view;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model user mode sketch map;
Label among the figure: 1 conduit; Bottom, 2 holes; 3 layer of concrete; 4 top of concrete; 5 mud layers; 6 steel pipes; 7 slag buckets;
The specific embodiment
As shown in Figures 2 and 3, a steel pipe 6 that has the length graduated scale is set, fixedly installs a slag bucket 7 at the front end of steel pipe 6, slag bucket 7 is to be headwall with the reinforced mesh.
Method for using is: when the design altitude of drilled pile concrete spouting to the top of arrival stake soon, strengthen the hole depth measuring frequency.When prediction concrete end face has risen to design elevation; Utilize this concrete appliance with slag bucket directly to design altitude position, stake top; And then outside the proposition drilled pile,, just can judge concrete and whether pour into to design elevation through the slag specimen of getting in the slag bucket is analyzed.If do not arrive, commander led on-the-spotly continue concrete perfusion, and repeat sample analysis, can think that concrete has poured into put in place that until salvage up-to-standard concrete in design elevation position, stake top the scene can stop concrete spouting.
Claims (1)
