10. The construction method of the anti-collapse pit digging device for the soft foundation construction of the municipal road according to claim 9, characterized by comprising the following steps: the method comprises the following steps:
the method comprises the following steps that firstly, the device is moved to a position where punching is needed, the screw rod (13) is moved to correspond to the punching position, and the position of the device is adjusted through rotation of the rotating wheel (2) in the moving process;
step two, the first soil limiting piece (11) and the second soil limiting piece (12) are pushed to extend through the first hydraulic telescopic rod (7), meanwhile, the screw rod (13) can be driven to longitudinally move downwards, the first soil limiting piece (11) and the second soil limiting piece (12) can longitudinally move downwards to divide soil around a drilling position, the screw rod (13) can be output by the output motor (8) in the dividing process, and the screw rod (13) can break and upwards transmit the divided soil;
step three, discharging the smashed soil through a soil discharging opening (14) after the smashed soil is limited by a first soil limiting sheet (11) and a second soil limiting sheet (12) in the process of moving upwards, and wrapping the discharged soil through a screw rod (13) so as to facilitate the subsequent use of the soil;
step four, in the process of punching the screw rod (13), a motor drives the corresponding transmission threaded rod (24) to rotate, relative motion can be generated between the rotation of the transmission threaded rod (24) and the transmission rod (25), after the outside of the transmission rod (25) is limited by the containing frame (9), the rotation motion is converted into linear motion, and then the third support rod (10) is pushed, and the third support rod (10) can push the corresponding first soil limiting sheet (11) and the corresponding second soil limiting sheet (12) to move outwards;
fifthly, the soil around the punching position can be squeezed by moving the first soil limiting sheet (11) and the second soil limiting sheet (12), so that the soil can be prevented from loosening by squeezing the soil, and the soil can be prevented from collapsing;
step six, before hob (13) punches, thereby stretch into inside earth through the extension of second hydraulic telescoping rod (15), the in-process of stretching into, the restriction because of earth can make stationary blade (17) use damping pivot (20) to rotate as the centre of a circle, stretch into to the relative position after, can restrict stationary blade (17) by the resilience of the damping collocation reset spring (22) of damping pivot (20), the position of stationary blade (17) receives can snatch earth after the restriction, thereby avoid causing the device position to produce the skew at the in-process that punches.
