Abstract
The invention relates to a building envelope for internally inserted structural steel of a multi-shaft cement soil stirring wall and a construction method of the building envelope. The vertical building envelope comprises stirring piles and internally inserted structural steel. The construction method comprises the following steps of (1) constructing the multi-shaft cement soil stirring piles by using a novel FCW (forward collision warning) construction method; and (2) inserting the structural steel: hoisting the structural steel through a crawler crane before initial setting of the cement soil stirring piles, and inserting the structural steel in the piles by the weight of the structural steel to form composite stress piles. Compared with the traditional stirring pile process, the construction method has the advantages that the used equipment and the piling mechanism are different from those of the traditional stirring pile process, the strength and the uniformity of pile bodies of the piles which are formed by using the FCW construction method are obviously higher than those of the traditional process, the perpendicularity of the pile bodies, the parallelism of the piles and the lap joint degree of the pile bodies are quite high, the waterproofness is high, and the structural steel can be inserted in the piles and recycled conveniently.
Description
Technical field
The present invention relates in a kind of engineering soft rock-soil to reinforce and support technology, especially relate to a kind of novel stiffness cement-soil stirring pile construction method, effectively the reduction of erection time, reduce construction costs greatly.
Background technology
Concrete Core Mixing Pile occurs more late in China, and in Japan, Southeast Asian countries, occurs already and extensive use, and the existing more application abroad of " SMW " engineering method diaphragm wall." SMW " engineering method is a kind of diaphragm wall novel construction method of Japan's invention in 1976, to grow up on the basis of cement mixing method and diaphragm wall, before cement mixing method initial set, insert the H shaped steel of stiffness as beaer, form the continuous jointless stiffness cement-soil structure with some strength and rigidity.In recent years, China's base pit engineering three axle agitation piles are in order to obtain good cement grout mobility and pile body uniformity, this engineering method is that to take intensity and the construction cost per square meter of pile body be cost, and three axle agitation piles produce a large amount of displacement soil in work progress, the soil body displacing is alkalescence, cannot return farmland, cause a large amount of pollutions.Agitation pile involved in the present invention is novel five (six) axle Soil-cement Walls (hereinafter to be referred as FCW engineering method), this engineering method is used novel intellectuality five (six) axle ram machine constructions, once at most can pile five (six) roots, without displacement soil, solved to a certain extent the deficiency of above-mentioned several agitation pile techniques, have efficient, without the feature of displacement, intelligent, environmental protection.
Summary of the invention
Object of the present invention is exactly to provide a kind of short construction period, mechanization degree Concrete Core Mixing Pile construction high, little to surrounding environment influence, that give birth to without displacement local products in order to overcome the defect of above-mentioned prior art existence.
Object of the present invention can be achieved through the following technical solutions:
Multi-shaft cement stirs a space enclosing structure of inserting within the walls shaped steel, and this vertical space enclosing structure comprises New type agitation stake and interpolation shaped steel.
Many of described New type agitation stake one-shot formings.
It is raw that local products are not replaced in described New type agitation stake in work progress.
Described New type agitation stake is constructed by the agitation pile machinery (five axles or six axles) of the distributed bull stick of multiaxis.
Described interpolation steel section size can be different, and shape also can be different.
It can be close slotting form that described interpolation shaped steel distributes.
It can be the form that insert at interval that described interpolation shaped steel distributes.
Described interpolation shaped steel inserts before agitation pile initial set.
A kind of multi-shaft cement stirs the construction method of the vertical space enclosing structure of slotting shaped steel within the walls and comprises two procedures: first operation is the construction method of novel FCW engineering method multi-shaft cement agitation pile; Second operation work is the insertion of shaped steel, before cement mixing method initial set, by the machine crawler crane shaped steel of slinging, by shaped steel deadweight, is inserted in pile body, can shaped steel be pressed into design elevation by external force if desired.
Compared with prior art, the present invention has the following advantages:
1, efficiency of construction of the present invention is high, and the disposable pile radical of agitation pile is many, and the probability of cold seam outlet is little, and, environmental protection raw without displacement local products, and pile body uniformity is better than common agitation pile, is beneficial to like this insertion and the recovery of shaped steel;
2, than traditional soil-baffling structures such as traditional castinplace pile campshed, SMW engineering methods, cost aspect can reduce by 30% left and right.
