Detection device for evaluating post-grouting compressive strength of load box

The utility model belongs to the technical field of constructional engineering material quality detection devices, and particularly relates to a detection device for evaluating post-grouting compressive strength of a load box. The detection device comprises load box post-grouting equipment, a grouting pipeline, a grout return pipeline and a grouting load box. A grout output port of the load box post-grouting equipment is connected with the grouting load box through a grouting pipeline; and the grout return pipeline is connected with the grouting load box. The device is simple, convenient to operate, good in safety and high in practicability. Through the device provided by the utility model, a target cylindrical test piece required by subsequent tests can be quickly and conveniently obtained. According to the concrete test piece obtained by the utility model, the compressive strength can objectively and truly reflect the performance of a cast-in-place concrete member, so that a reliablebasis is provided for de
