Problems solved by technology
[0004] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: in the pile connection construction of existing building pile foundation, often simply rely on manually to carry out the pile connection construction of filling pile foundation and existing pile foundation, time-consuming and laborious, And it is easy to appear that the pile foundation and the central axis of the existing pile foundation are not on the same vertical line, which will affect the safety of later construction. A construction device for connecting piles to existing pile foundations inside the soil is proposed

The invention discloses a construction device for pile extension of an existing pile foundation inside a soil mass. The construction device comprises a circular truncated cone, wherein a placement port is formed in the central position of the upper surface of the circular truncated cone; a plurality of hydraulic cylinders are fixedly arranged on the outer side wall of the circular truncated cone;a backing plate is fixedly connected to the lower end of each hydraulic cylinder; travelling wheels are arranged at the bottom of the circular truncated cone; the circular truncated cone is internallyprovided with a first mounting cavity; a mounting opening communicated with the first mounting cavity is formed in the upper surface of the circular truncated cone; the mounting opening is internallyand fixedly provided with a ball bearing; an inserted link is inserted into the ball bearing; the outer side wall of the inserted link is fixedly connected with an inner ring of the ball bearing; a first stepping motor is fixedly arranged at the inner bottom of the first mounting cavity; a first gear is fixedly arranged at the output end of the first stepping motor in a sleeving manner. The construction device disclosed by the invention adopts mechanical construction to replace manual operation so as to obtain higher efficiency and better pile extension matching result.
Description
technical field [0001] The invention relates to the technical field of pile foundation pile connection construction devices, in particular to a construction device used for pile foundation pile connection in existing pile foundations inside the soil. Background technique [0002] As early as the Neolithic Age 7,000-8,000 years ago, in order to prevent the invasion of beasts, people once planted wooden piles in lakes and swamps to build platforms to build settlements. Such settlements are called lake dwellings. In China, the earliest pile foundations were found in the ruins of the primitive society in Hemudu, Zhejiang Province. By the Song Dynasty, pile foundation technology had been relatively mature. In "Building French", there is a section on building foundations by facing water. In the Ming and Qing dynasties, the pile foundation technology became more perfect. For example, the book "Engineering Practices of the Ministry of Industry" in the Qing Dynasty has regulation...
