Further setting the following steps: the survey hammer body includes integrated into one piece's column portion and centrum portion, the cavity is located in the column portion, centrum portion down and the minimum is the zero point value of survey rope.
Through adopting above-mentioned technical scheme, the survey hammer body comprises column body portion and centrum portion, and the column body portion is used for guaranteeing the dead weight of survey hammer body and makes the proportion of survey hammer body can be the same with concrete proportion, and centrum portion can reduce the resistance that the survey hammer body received in the concrete, reduces the wearing and tearing of survey hammer body in the concrete.
Further setting the following steps: and the outer surface of the measuring hammer body is coated with an antirust coating.
Through adopting above-mentioned technical scheme, though the survey hammer body is the stainless steel hammer, but because the composition is complicated in the concrete, wherein multiple organic auxiliary agent reacts with the iron element in the stainless steel hammer easily and leads to the stainless steel hammer to be corroded, consequently at the surface coating anti-rust coating of survey hammer body, the corrosion resisting property of reinforcing survey hammer body, the life of extension survey hammer body.
Further setting the following steps: the force measuring end of the dynamometer is fixedly connected with a hanging ring, a rope winding rod is fixed on the hanging ring, one end of the measuring rope is connected with the measuring hammer body, and the other end of the measuring rope penetrates through the hanging ring and then is wound and fixed on the rope winding rod.
By adopting the technical scheme, the length of the measuring rope is generally longer due to the fact that the measuring rope is suitable for construction sites with different conditions, when the length of the measuring rope is larger than the distance from the concrete surface elevation to the top surface of the cast-in-place pile, the measuring rope can be wound around the hanging ring and then is wound and fixed on the rope winding rod, and the length of the measuring rope is adjusted more conveniently.
Further setting the following steps: the top of the column body part is provided with a hanging ring, and one end of the measuring rope is tied to the hanging ring.
Through adopting above-mentioned technical scheme, the top of cylinder portion sets up rings and the survey rope through tying up on rings with survey hammer body fixed connection, when needs are changed survey hammer body or survey rope, can unbundle the survey rope from rings, changes the part that needs to be changed, avoids changing wholly, reduces extravagantly.
To sum up, the utility model discloses a beneficial technological effect does:
(1) the method comprises the following steps that a support is arranged right above a cast-in-place pile, a dynamometer is arranged on the support, a measuring rope and a measuring hammer body are hung below the dynamometer, the specific gravity of the measuring hammer body is the same as that of concrete, when the elevation of a concrete surface reaches the elevation related to the concrete elevation, the concrete just completely submerges the measuring hammer body, the buoyancy force borne by the measuring hammer body is equal to the self gravity, the tension of the measuring rope is zero, the number of readings of the dynamometer is zero at the moment, the elevation of the concrete surface is obviously sensed to reach the required control elevation, and the pouring amount of the underwater concrete is controlled more accurately;
(2) the measuring hammer body is a stainless steel hammer, and the surface of the measuring hammer body is coated with the antirust coating, so that the corrosion resistance of the measuring hammer body is enhanced, the measuring hammer body is more durable, and the service life of the measuring hammer body is longer.
