Foundation bearing capacity detection device used for road construction and capable of improving stability

Abstract

The invention relates to the technical field of foundation detection, and discloses a foundation bearing capacity detection device used for road construction and capable of improving stability. The foundation bearing capacity detection device used for road construction and capable of improving stability comprises a shell, and an adjustment spring is movably connected into the shell; the end, awayfrom the shell, of the adjustment spring is fixedly connected with an electromagnetic coil; the side, close to the adjustment spring, of the electromagnetic coil is movably connected with adjustment rods; the side, away from the adjustment spring, of the electromagnetic coil is movably connected with a pendulum bob; two sides of the pendulum bob are movably connected with drilling rods; and the upper ends of the drilling rods are hinged to the adjustment rods. When the pendulum bob detaches from the electromagnetic coil, the adjustment spring moves upwards to drive the adjustment rods to moveupwards; the drilling rods are squeezed to move downward under the restriction of damping springs and buffer blocks while adjustment rods move upwards, and so on, and drilling bits are drilled into the ground so as to achieve the effect of detecting the strength of the ground; and when the foundation bearing capacity detection device is not used, supporting rods are folded to enable the supportingrods to be close to two sides of the shell, and the drilling bits are pushed into the drilling rods for easy carrying.

Description

technical field [0001] The invention relates to the technical field of foundation detection, in particular to a foundation bearing capacity detection device for road construction with improved stability. Background technique [0002] With the increase of infrastructure investment, engineering construction has sprung up like mushrooms after the spring rain. For shallow foundation engineering, the plate load test is usually used to detect the bearing capacity of the foundation, which requires a long time and high manpower and material resources. Dynamic penetration testing is a new type of A method for testing the bearing capacity of shallow foundations, but there is no buffer device at the feet of the existing dynamic penetrometer, and the mechanical vibration generated during the work of the dynamic penetrometer will affect the measurement results, and the traditional Storage has gradually been unable to meet people's needs for foundation bearing capacity measurement, so we ...

[0002] With the increase of infrastructure investment, engineering construction has sprung up like mushrooms after the spring rain. For shallow foundation engineering, the plate load test is usually used to detect the bearing capacity of the foundation, which requires a long time and high manpower and material resources. Dynamic penetration testing is a new type of A method for testing the bearing capacity of shallow foundations, but there is no buffer device at the feet of the existing dynamic penetrometer, and the mechanical vibration generated during the work of the dynamic penetrometer will affect the measurement results, and the traditional Storage has gradually been unable to meet people's needs for foundation bearing capacity measurement, so we have improved this and proposed a building foundation bearing capacity detection device

[0003] In the process of bearing capacity testing, the moving distance of the sliding hammer must be fixed, so that the magnitude of the impact force generated will be the same, and it will be practical for testing. However, in traditional testing equipment, with the guide rod and probe rod The movement of the sliding hammer reduces the movable space of the sliding hammer. There is not enough displacement distance, and the detection effect cannot be achieved, which is not practical. Moreover, the movement of the sliding hammer needs to be pushed by manpower, and there will inevitably be errors in the distance, which will bring problems to the measurement. Inconvenient, so a foundation bearing capacity testing equipment for road construction with improved stability came into being
