8. A method for detecting the bearing capacity of a foundation for detecting constructional engineering is characterized by comprising the following steps: the detection method employs the foundation bearing capacity detection device for construction engineering detection according to any one of claims 1 to 7, comprising the steps of:
s1, correspondingly placing the whole detection equipment on a foundation to be detected, pressing the top of an outer frame (1), gradually enabling an inner frame (18) to enter the support (7) due to the pressing pressure, driving the support (7) to move downwards by the outer frame (1), namely driving a lifting plate (20) to move upwards synchronously by an L-shaped frame (19) in the process that the inner frame (18) moves upwards on the inner side of the support (7), and driving a rotating sleeve (17) to rotate between two turning bars (21) by the lifting plate (20) in the moving process;
s2, when the inner frame (18) moves upwards on the inner side of the support (7), the inner frame (18) is limited by the rotation of the clamping groove (25) and the connector (24), the threaded strips (23) of the limiting groove and the rotating rod (22) are used for sliding limiting, so that the rotating rod (22) rotates anticlockwise on the inner side of the support (7) until the bottom surface of the inner frame (18) is correspondingly flush with the bottom surface of the support (7), and then the bottom ends of the four rotating rods (22) are rotationally inserted into the foundation, so that stable installation of the detection equipment and the foundation is completed;
s3, when the rotating sleeve (17) rotates, due to the limitation of the two turning bars (21) to the rotating sleeve (17) and the limitation of the side bars (16) to the rotating sleeve (17), the spiral effect of the rotating sleeve (17) and the side bars (16) enables the side bars (16) to gradually move out of the inside of the outer frame (1), and the side bars (16) pull the arc plate (9) to gradually be far away from the hammering block (2) in the process of moving out of the outer frame (1);
s4, when the two arc plates (9) cannot continuously clamp the hammering block (2), the weight of the hammering block (2) drives the detection rod (3) to move downwards until the bottom end of the detection rod (3) is impacted on the top surface of a foundation, the hammering block (2) drives the sliding block (5) to move downwards at the inner side of the vertical groove (6) by using the connecting rod (4) in the downward moving process, the detection rod (3) is prevented from shifting downwards in the downward moving process, the hammering block (2) is lifted repeatedly until the sliding block (5) is positioned at the top end of the vertical groove (6), the hammering block (2) is loosened, the weight of the hammering block (2) enables the bottom end of the detection rod (3) to be inserted into the foundation, and the depth of the detection rod (3) inserted into the foundation is quickly checked through scales on the surface of the detection rod (3);
s5, recording the depth of the detection rod (3) inserted into the foundation by multiple times of impact, wherein a detector is externally connected to the top end of the detection rod (3), detecting data of the multiple times of impact of the detection rod (3) are obtained by using the detector, and detecting the bearing capacity of the foundation is completed.
