It is understood that the dosage of concrete engineering in China every year is more than the sum of the dosages of other countries all over the world, and the concrete plays a considerable role in the development and construction of China as an important structural material. The strength of concrete is usually determined by pressure test of a manufactured concrete test block; in the engineering, the compressive strength of a structural entity is evaluated by adopting the remaining test blocks with the same conditions, and the test blocks with the same conditions are manufactured by material receiving when concrete is pumped to a template position and enters a mold. In the high-rise building pouring process, because the site conditions for manufacturing the test blocks are limited, the vibrating table cannot be applied to tap the concrete in the test mould, and only a manual inserting and tamping mode can be adopted. The manual tamping can not effectively remove micro bubbles in the fresh concrete, and has more uncontrollable factors, which easily causes great error between the strength of the test block cured under the same condition and the concrete strength of the structural entity, even causes the conditions that the concrete test block is unqualified and the drill core test piece of the structural entity is qualified, thus causing great trouble to the construction production.
