Double-low concrete and metal wire casing composite ground base construction method

Abstract

The construction method of double-low concrete and metal net cage composite ground base is characterized by laying woven galvanized wire net cage on the natural ground base to be treated, then depositing a layer of double-low concrete to form composite ground base plate, the thickness of said ground base plate is dependent on the requirements of the engineering. Said soft ground base treatment method is simple in construction process, quick in construction speed and low in engineering cost. The treated ground base is good in elasticity, small in settlement and its bearing capacity can be raised. Said invention can be used for treating soft ground base in the road construction in coasted area and swamp, etc.

Description

technical field [0001] The invention relates to a soft soil foundation treatment method, in particular to a construction method of a composite foundation using double-low concrete and metal net cages. Background technique [0002] The prior art related to the soft soil foundation treatment method of the double-low concrete composite ground slab is the existing foundation treatment method: such as drainage consolidation method, grouting reinforcement method, replacement method and compaction method, etc., and its relevant information can be obtained from " Code for Design of Building Foundation (GBJ7-89), or various books on foundation treatment, such as those introduced in the book "Foundation Treatment Technology" edited by the Continuing Education Committee of China Architectural Education Association. At present, there are many mature foundation treatment methods. According to the foundation treatment mechanism, there are the following categories: drainage consolidation m...

Problems solved by technology

The existing foundation treatment methods, such as drainage consolidation method and compaction method, have a permeability coefficient of only 10 -7 For foundations with a thicker silt layer of cm / s, the consolidation time is too long, and the construction period is not allowed, and because the permeability coefficient of silt is very small, the treatment effect will not be good; other treatment methods such as replacement method, grouting method, etc. If the local sand and soil have to be shipped out, the cost is not low

Moreover, these foundation treatment methods require medium and heavy-duty equipment. In addition, if the sea area has two tides every day, the equipment must be removed when the tide comes during the construction period, and the equipment must be installed when the tide ebbs. These methods have their advantages, disadvantages and scope of application.
