Background
A high-pressure rotary jet pile is a common supporting method, which includes drilling hole with drilling machine, lowering the jet pipe with special nozzle to preset position, strong impacting and destroying soil layer with high-pressure jet flow, stripping fine particles from soil layer under the action of high-pressure jet flow and discharging them out of ground, mixing the rest of soil layer with grout, and solidifying to obtain grout-soil concretion. In order to increase the tensile strength and the shear strength of the high-pressure jet grouting pile, after the high-pressure jet grouting is finished, the section steel is inserted into the high-pressure jet grouting body, the section steel bears the tensile pressure and the shear pressure by utilizing the combined action of the section steel and the jet grouting body, and the jet grouting pile body stops water and prevents seepage to form a bearing and waterproof composite structure.
In order to reduce the construction cost, after the main body engineering is finished or a foundation pit is backfilled, the section steel is usually required to be pulled and recycled, and a cavity formed by the section steel is backfilled. At present, the section steel of the high-pressure jet grouting pile is pulled out and recovered by a crawler crane directly, but when the crawler crane is pulled out, the controllability of the pulling force direction is poor, the section steel is easy to deform, and the pulling difficulty is increased.

The working principle of the utility model is as follows: when the section steel pulling device is used, firstly, through holes are punched in the parts, exposed out of the ground, of section steel (including but not limited to H-shaped steel and I-shaped steel) in the high-pressure jet grouting pile, then the section steel pulling device is moved to the position above the section steel, the jack is adjusted, the through holes in the section steel are aligned with the jack, then the pulling rod is inserted into the jack and the through holes, the limiting bolts are installed at the tail end of the pulling rod, the section steel is connected with the pulling assembly through the pulling rod, the jack is started, the jack pushes the beam plate upwards, the beam plate drives the pulling assembly upwards, and the pulling assembly pulls the section steel upwards.
The utility model has the beneficial effects that: according to the profile steel pulling device, the profile steel is firstly pulled out from the rotary spraying pile body by the profile steel pulling device, and then the profile steel is pulled out by the crawler crane, so that the profile steel is prevented from deforming, and the pulling difficulty is reduced. The device has simple structure and convenient use, and can quickly and stably pull out the section steel in the high-pressure jet grouting pile. In addition, the pulling assembly of the device can be adjusted up and down, the distance is adjustable, the device can be suitable for pulling operation of profile steels of different specifications, and the practicability is high.
