Improved device for pine pile non-disturbance enclosure construction and construction method thereof

Abstract

The invention belongs to an improved device for pine pile non-disturbance enclosure construction and a construction method thereof. The improved device comprises a vehicle body, an engine assembly, an operation room, a crawler belt running system, a first mechanical arm, a second mechanical arm, a first hydraulic cylinder, a second hydraulic cylinder and a third hydraulic cylinder, wherein the third hydraulic cylinder is arranged at the upper end of the second mechanical arm, a telescopic rod of the third hydraulic cylinder is connected with a grabbing and pressing device located at the front end of the second mechanical arm, and a drilling device is arranged at the lower end of the second mechanical arm. The method comprises the steps of device improvement, material preparation, construction lofting, pile planting construction which is divided into interval jumping type pile planting operation and the like. The improved device can work in the space close to historical protection buildings, residential areas and hospitals, disturbance to surface soil can be reduced, and the improved device has the advantages that the number of workers is small, the construction speed is high, and existing equipment can be quickly improved to be suitable for pine pile enclosure construction.

Description

technical field [0001] The invention belongs to an improved equipment for the non-disturbance enclosure construction of pine piles and a construction method thereof. Background technique [0002] Historical buildings need to be protected, so it is very difficult to construct underground around historical buildings. It is usually required that the historical buildings are not disturbed or the disturbance is as small as possible during construction. Currently, steel sheet piles are mostly used for underground construction, which has high construction costs. During the construction process, the soil is squeezed and vibrated greatly, and the enclosure construction process causes great damage to the historically protected buildings. The above-mentioned problems also exist in the enclosure construction near residential areas and hospitals. Existing pine pile enclosure construction is manual pile driving with air hammer machine, and the stored pressure has the disadvantages of soil...

Problems solved by technology

[0002] Historical buildings need to be protected, so it is very difficult to construct underground around historical buildings. It is usually required that the historical buildings are not disturbed or the disturbance is as small as possible during construction. Currently, steel sheet piles are mostly used for underground construction, which has high construction costs. During the construction process, the soil is squeezed and vibrated greatly, and the enclosure construction process causes great damage to the historically protected buildings. The above problems also exist in the enclosure construction near residential areas and hospitals.

The existing pine pile enclosure construction is manually driven with an air hammer machine, and the stored pressure has the disadvantages of soil extrusion and vibration, large number of people, and slow construction speed.
