Embodiment Construction
[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0022] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a small-diameter rapid pile pulling device for civil engineering and its use method include a base 1, a guide tube 2 is fixedly connected to the top of the base 1, and a plurality of rolling balls are evenly embedded on the outer wall of the guide tube 2 3. A top ring 4 is fixedly installed on the top of the guide tube 2, and a sleeve 5 is attached to the outside of the top ring 4. The bottom end of the sleeve 5 is attached to the top of the base 1. The sleeve 5 Four through grooves 6 are evenly arranged on the bottom of the outer wall, and four fixing blocks 7 are uniformly fixedly installed on the bottom of the outer wall of the casing 5, and the four fixing blocks 7 are arranged opposite to the four through grooves 6, and the fixing blocks 7 are arranged in t...

The invention discloses a small-diameter quick pile-extracting device for civil engineering and a method for using the same. The top ring, the top ring is fitted with a casing, and the bottom of the casing is fitted with the top of the base. The device can effectively prevent part of the soil from returning to its original position by setting a guide plate, ensuring the normal operation of the device and strengthening The plate ensures the normal operation of the track and prevents the collapse caused by the small pressure of the soil layer. It is equipped with multiple stabilizing bars to ensure the stability of the shape and structure of the U-shaped block. Using four U-shaped blocks and the bottom of the pile body Fitting, so that the pile body is pulled out, the first magnetic block and the second magnetic block are provided, and the magnetic force is used for adsorption, which is convenient for reset. After inserting the positioning pin, the reset and fixation of the U-shaped block is completed, thereby completing the storage of the pile body. The operation is simple and convenient, which greatly improves the work efficiency.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a small-diameter quick pile pulling device for civil engineering and a method for using the same. Background technique [0002] Pile lifting devices are often used in civil engineering, and the existing pile lifting methods are roughly divided into two types, one is the full-rotary drilling rig pile pulling method: it has a unique effect on bored piles that are prone to uneven pile diameters , that is to say, it is very suitable for cast-in-situ piles with collapsed or pregnant piles during construction. But for pulling out other prefabricated square piles, sinking pipe grouting piles, and prestressed pipe piles, the price of this equipment is too high, the construction efficiency is low, and the pile pulling cost is high. During the pile pulling process, the equipment will generate hundreds of tons of reaction force on the ground. If the foundation is not firm, it will have a g...
