Abstract

The invention relates to an auxiliary device and a penetration method for ensuring the verticality and angle of the penetration of model piles, belonging to the technical field of building pile foundation engineering. The model pile is penetrated on the high soil surface; the actual piling process is simulated by using the hammering module and the static pressure module; the hammering module realizes the driving of the model pile through the reciprocating free fall motion of the heavy hammer. The actual oil hammer pile driver is consistent, and the simulation of different hammering energies can be realized by changing the weight of the heavy hammer; the static pressure module is similar to a reciprocating motion mode, which is also similar to the static pressure process of the actual pile foundation. It is more similar; the alignment of the model pile and the loading equipment can also be achieved through the two aiming lines on the pile clamp cover, which provides a reliable guarantee for the study of the pile driving construction process and the bearing capacity of the pile foundation, and ensures the test data. accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of building pile foundation engineering, in particular to an auxiliary device and a penetration method for ensuring the verticality and angle of penetration of a model pile. Background technique [0002] Pile is an effective means to improve the bearing capacity of foundation. There are many types of piles, among which the prefabricated piles are widely used in the construction of major foundation projects due to their fast construction speed, large load bearing, firmness and durability. However, such piles may have a negative impact on the surrounding soil or structures during construction, because prefabricated piles are generally driven, pressed or vibrated into the soil by pile driving equipment. [0003] In scientific research in the field of geotechnical engineering, the bearing characteristics of pile foundations are one of the topics that engineers pay special attention to. Research methods include...
