Novel low-position water draining body suitable for ultra-low-position vacuum pre-pressing method

Abstract

The invention provides a novel low-position water draining body suitable for an ultra-low-position vacuum pre-pressing method. A spatial lattice type keel frame is adopted for the water draining body,and a water draining passage and a vacuum transmitting passage are formed in the inner spatial part of the spatial lattice type keel frame. Water inflow holes and vacuum transmitting holes are formedin a keel frame body, and a vacuum conduction pipe hole is reserved in the centroid of the cross section of the keel frame. A vacuum conduction pipe is embedded into the vacuum conduction pipe hole and connected with the spatial lattice type keel frame through a lower end head. The water draining body adopts the ultra-low-position vacuum pre-pressing method, the water draining efficiency can be effectively improved through the low-position water draining mode, the phenomena of bending, folding, blocking and the like of an original water draining body are reduced or eliminated, and the problem, existing in the construction process, of an original vacuum pre-pressing system is fundamentally solved.

Description

technical field [0001] The invention belongs to a device for foundation reinforcement, and particularly relates to a new low-level drainage body suitable for ultra-low-level vacuum preloading method. The drainage body is especially suitable for reinforcement treatment of large-area and high-water-content deep dredging-filled soft clay foundations in coastal areas. . Background technique [0002] With the development of society, people's pursuit of the quality of living environment is increasing day by day, especially the pursuit of a wide living space. The existing land can no longer meet the large-scale development of cities. Land reclamation is an effective way to solve land resources. Building a city full of high-rise buildings on the filled soil requires a solid foundation, but the strength of the filled soil is extremely weak. Therefore, improving the strength of the filled soil is a necessary condition for urban construction. [0003] The vacuum preloading method is a...

Problems solved by technology

This drainage method makes the soil laterally deform inward easily, squeezes the drainage path of the drainage body, and causes the original drainage body to be easily blocked, twisted, folded, broken, etc. during the working process, resulting in poor drainage during the soil reinforcement process. Smooth, unsatisfactory reinforcement effect
