(2) starting the concrete distributing and stirring device: the materials are conveyed into the material tanks, the materials required by the test are guided into the weighing hoppers below the material tanks through valves by the material tanks, after the weighing of the weighing hoppers meets the requirement, the materials are guided into the stirrer below the material tanks through the valves to be stirred, and the materials are output from a discharge port of the stirrer after being stirred; (3) the cement pumping pouring device and the pouring device above the vibrating table work in the civil engineering laboratory, a vision camera is fixed on the temporary storage tank, and the height of poured concrete can be fed back by the vision camera by marking the mould, so that the output concrete amount is controlled by using a battery valve or a negative pressure pump; (4) introducing the stirred concrete into a mould, realizing uniform filling of materials under the driving of a vibrating motor, clamping a film conveying roller between two clamping plates by using a clamp, and then locking the two clamping plates by using bolts; (5) the support electric cylinder drives the two vertical supports to move synchronously, then the vertical supports move in an initial state, the lower edge of the compression roller is lower than the surface of concrete to be trowelled, the support electric cylinder drives the vertical supports to move, so that the swing rod and the compression roller are driven to move together with the clamp, when the compression roller contacts the mold, the mold is fixed on the upper support table, then the mold is propped against the mold to swing upwards passively, then the mold bypasses the upper edge of the mold, then the mold continues to move transversely under the action of the support electric cylinder, and the compression roller is pressed on the surface of the concrete in the mold under the action of gravity to roll and form a plane; (6) because the clamp is fixed at the rear side of the swing rod positioned at the compression roller, in the moving process of the vertical bracket, the swing rod drags the clamp to drag the thin film to cover the rolled concrete surface in the mould after the compression roller is pressed, and then the thin film is cut off; (7) under the condition that a reinforcing bar net needs to be placed, before concrete is led into a mould, reinforcing bars are placed in a reinforcing bar discharging hopper along the axial direction of a reinforcing bar output roller by using a reinforcing bar bundling device, the reinforcing bars can fall into a groove when meeting the groove of the reinforcing bar output roller along with the rotation of the reinforcing bar output roller, the depth of the groove of the reinforcing bar output roller can only fall into one reinforcing bar, the groove directly falls to the lower part when being exposed from a discharging opening below the reinforcing bar discharging hopper along with the rotation of the reinforcing bar output roller, at the moment, along with the movement of a sliding seat electric cylinder, a rectangular frame moves along the direction parallel to the axial direction of the reinforcing bar output roller, the reinforcing bars falling from the discharging opening fall into each reinforcing bar fixing seat in the same row one by one, after the same row of reinforcing bars fall into the same row of reinforcing bars, the rotation degree of a frame motor can be continuously set up in the same direction to be vertical to the upper part of the previously placed reinforcing bars, so as to complete the arrangement of the reinforcing bars forming the reinforcing bar net, binding the staggered positions of the transversely and longitudinally staggered steel bars to complete the manufacturing of the steel bar mesh, and then placing the finished steel bar mesh into a mold to be poured through a mechanical device for standing to prepare a test piece; (8) after the test piece is manufactured, the test piece is sent into a test piece positioning seat of the testing equipment through a manipulator; (9) lifting a lower hydraulic lifting seat supporting the test piece positioning seat in the test equipment, and separating the manipulator after the test piece is preliminarily pressed by an upper hydraulic lifting seat and a lower hydraulic lifting seat in the test equipment; (10) adjusting a displacement meter moving device in the test equipment until a contact of the displacement meter contacts the surface of the test piece; three sets of displacement meters capable of being adjusted in three axes are arranged on the displacement meter moving device, and contact contacts of the three sets of displacement meters are respectively aligned to one fourth, one half and three quarters of the total height in the same vertical surface of the test piece; (11) starting a continuous pressing test by an upper hydraulic lifting seat in the test equipment; (12) and in the process of continuously pressing down the upper hydraulic lifting seat, the contact points of the three groups of displacement meters are lowered, the descending values of the three contact points from bottom to top are one fourth, one half and three fourths of the descending value of the upper hydraulic lifting seat, and the three contact points are ensured to be in contact with the surface of the test piece.
