Water surface tamping device for civil construction foundation pile

Abstract

The invention provides a water surface tamping device for a civil construction foundation pile, and relates to the technical field of civil construction. A bearing groove is formed in the edge of the top surface of a cushion table; a plurality of vertical moving ways are uniformly formed in the cushion table and located under the bearing groove; the moving ways downwards penetrate through the bottom surface of an operation ship; limiting ways are symmetrically formed in the inner walls of the moving ways; sleeve shafts are embedded in the tops of the movable ways; air bags are embedded in the inner walls of the sleeve shafts; the interiors of the movable ways are movably connected with movable rods; and the bottom ends of the outer walls of the movable rods are symmetrically provided with inner grooves. Soil is input into a loose soil position from an input pipe, the soil is conveyed to the loose soil position, the soil is used for filling, and the soil can be supplemented in time, so that the compaction degree of the soil is enhanced, the firmness of the building foundation pile is improved, the problems that an underwater environment is poor, soil is poor in quality, the foundation pile tamping process is very difficult, a manual launching tamping mode is adopted for work, the work progress is short, and the effect is poor are solved.

Description

technical field

[0001] The invention relates to the technical field of civil construction, in particular to a water surface tamping device for foundation piles of civil construction. Background technique

[0002] Civil engineering is a general term for the science and technology of building various engineering facilities. It not only refers to the applied materials, equipment and technical activities such as survey, design, construction, maintenance and repair; Various engineering facilities for production, military and scientific research services, pile foundation: a foundation composed of piles and caps connected to the pile tops. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Construction pile foundations are usually low cap pil...
