The utility model discloses can carry out the sample detection to pile bolck concrete when concreting in the stake, the accurate laitance and real concrete of distinguishing are guaranteeing under the prerequisite of pile foundation construction quality, and furthest saves the concrete.
Description
Technical Field
The utility model belongs to the technical field of bridge pile foundation construction, when relating to concrete placement in the bored concrete pile, highly carry out the device that detects to pile bolck concrete.
Background
When concrete is poured into the cast-in-situ bored pile, the height of the concrete at the top of the pile needs to be controlled, and the height of the concrete is preferably controlled to be 0.5m higher than the designed pile top. Because the pile top elevation is located the certain degree of depth of below ground, and the top has the laitance of the uncertain thickness of one deck during concrete placement, influences the judgement to actual concrete height, therefore pile top concrete height is difficult to control, the problem that exists at present in the construction, firstly concrete placement height is not enough, has influenced pile head quality, secondly in order to guarantee to become the stake quality, often pours concrete more, so not only causes the concrete waste, has increased the work load that later stage pile head was abolished moreover.
Disclosure of Invention
The utility model aims at solving the above problems, and provides a cast-in-situ bored pile pouring height detection device, which is convenient for accurately controlling the height of the concrete on the pile top when the concrete is poured in the pile.
The technical scheme of the utility model as follows:
the utility model provides a cast-in-situ bored pile pours high detection device which characterized in that: the device comprises a probe rod, wherein length scales are arranged on the probe rod, a probe is arranged at the lower end of the probe rod, a screw rod is arranged at the upper end of the probe and is in threaded connection with the lower end of the probe rod through the screw rod, the lower end of the probe is of a pointed structure, and a sampling box is welded on one side of the probe; the sampling box is of a cone structure, the cone tip of the sampling box faces downwards, the upper end of the sampling box is open, and one side of the sampling box is welded with the probe.
The utility model discloses can carry out the sample detection to pile bolck concrete when concreting in the stake, the accurate laitance and real concrete of distinguishing are guaranteeing under the prerequisite of pile foundation construction quality, and furthest saves the concrete.

Detailed Description
As shown in fig. 1, 3 and 4, the utility model comprises a probe rod 1, length scales are arranged on the probe rod, a probe 2 is arranged at the lower end of the probe rod, a screw 21 is arranged at the upper end of the probe and is in threaded connection with the lower end of the probe rod 1 through the screw, the lower end of the probe 2 is in a pointed structure, and a sampling box 3 is welded at one side of the probe; the sampling box 3 is of a cone structure, the cone tip of the sampling box faces downwards, the upper end of the sampling box is open, and one side of the sampling box is welded with the probe.
The utility model discloses during the implementation, probe rod 1 can adopt two at least probe rod segments to connect and form. As shown in fig. 2, each probe rod segment 11 has a screw 12 at the upper end and a screw hole 13 at the lower end. The screw rod at the upper end of one probe rod section is in threaded connection with the screw hole at the lower end of the other probe rod section, and the probe is in threaded connection with the screw hole at the lower end of the lowermost probe rod section.
In specific implementation, the length of each probe rod section is preferably 1m, and a length scale 14 is arranged on each probe rod section every 10 cm. And a serial number is marked on each probe rod section, so that the length of the whole probe rod can be calculated conveniently.
As shown in fig. 5, according to the distance between the designed elevation of the pile top of the bored pile 4 and the ground, a proper number of probe rod segments are adopted to connect into a probe rod 1 with a proper length, a probe 2 and a detection box 3 are arranged at the position 0.5m above the designed elevation of the pile top in the pile hole, when concrete in the pile is poured to the position, a sample is taken out at any time through the sampling box, whether the sample is laitance or real concrete is detected, if the sample is laitance, pouring is continued, and if the sample is concrete, pouring is stopped immediately. Therefore, the pile head quality can be ensured, the concrete pouring is not overhigh, and the waste is avoided.
