Abstract
The invention relates to a construction method of a horizontal cement-treated soil stirring pile and a shed pile of the horizontal cement-treated soil stirring pile. The construction method of the horizontal cement-treated soil stirring pile adopts the following steps that: firstly, a cement-treated soil agitator mill is adopted to carry out reciprocating mechanical stirring along the longitudinal direction of a pile body on a soil body at the position of a leveling peg, and the cement or the mixture of the cement and pulverized fuel ash or the cement solidification slurry are spurted into the pile body so as to form a continuous and compact horizontal cement-treated soil stirring pile body. The construction method of the horizontal cement-treated soil stirring pile of the invention can be applied for the construction of an anchor rod and is also applied in the excavation and supporting of a horizontal grotto. The method has simple construction, low cost, less environmental pollution and can ensure the intensity of the horizontal cement-treated soil stirring pile.
Description
Technical field
The invention belongs to civil construction, municipal engineering field, especially relate to the job practices of level to cement mixing method and stake canopy thereof.
Background technology
At present among the excavation supporting of the horizontal cavern in subway, tunnel, level has horizontal jet grouting and Guan Peng to the job practices of stake canopy.Horizontal jet grouting is to adopt minor diameter drill bit pore-forming, relies on the pressure of water under high pressure mud or cement paste and water, gas then, utilizes the high-pressure spray that sprays that the soil body is stirred, and finally forms larger-diameter soil mass consolidation; Pipe canopy method be the employing level to steel pipe along about the underground chamber and the top arrange, or adopt interconnected steel pipe or slip casting between steel pipe, formation is reinforced the soil body of cavern's periphery so that the soil excavation of cavern, but all there are some problems in above-mentioned two kinds of technology: little as the horizontal jet grouting drill bit, and the pile diameter is big, stake is directly difficult to be guaranteed, relies on the cement paste jet that the soil body is stirred pile, has problem long in time limit, that discharging is given up and starched, cost is high; The pipe canopy exists that ejection for water plugging effect between cost height, the steel pipe is wayward, the shortcoming of stressed effect difference.
Summary of the invention
Main purpose of the present invention is in order to solve the deficiency of above-mentioned background technology, and it is simple to propose a kind of construction, and cost is low, and environment pollution is little, and level that can guaranteed strength is to the job practices of cement mixing method.
For achieving the above object, the present invention adopts following technical scheme: level is to the job practices of cement mixing method, this method adopts following steps: at first adopt the cement-soil mixing plant that the soil body of leveling peg position is vertically carried out the reciprocating machine stirring along pile body, and slurry (including cement, water glass, flyash, early strength admixture) is solidified in the mixture or the cement system of jet cement or cement and flyash in pile body, forms fine and close continuously level to the cement mixing method pile body.
After the construction of above-mentioned pile body, can in the pile body unit, insert stressed core, formation with the level of stressed core to cement mixing method.
This method construction is simple, and cost is low, and environment pollution is little, and energy assurance level is to the intensity of cement mixing method.
Another goal of the invention of the present invention is to propose a kind of construction simply, and cost is low, and environment pollution is little, and fine and close continuously level is to the job practices of cement mixing method canopy.
For realizing this purpose, the present invention adopts following technical scheme: a kind ofly utilize above-mentioned level to carry out the job practices of level to the cement mixing method canopy to the job practices of cement mixing method, this canopy is overlapped side by side by several leveling peg body units to be formed, constructing as follows in each pile body unit: at first adopts the cement-soil mixing plant that the leveling peg canopy position soil body is vertically carried out reciprocating machine along each pile body unit and stir, and slurry is solidified in the mixture or the cement system of jet cement or cement and flyash in this pile body unit, forms fine and close continuously pile body unit.
In such scheme, the sequence of construction of described stake canopy king-pile body unit is preferably: construction two pile body unit at interval earlier, the above-mentioned two pile body unit between the pile body unit at interval of constructing again form a stake canopy.
This method construction is simple, and cost is low, and environment pollution is little, and energy assurance level is to the intensity and the continuous compactness of cement mixing method canopy.
Characteristics of the present invention and advantage are as follows:
1, adopt the mechanical agitation pile, bit diameter equals the pile body diameter, and expanded diameter guarantees easily;
2, adopt twin tip drill or bull to be drilled to stake, the more continuous densification of overlap joint between the pile body, supporting effect is better.
3, do not discharge mud, free from environmental pollution.
4, work efficiency height, cost is low.
5, because of not discharging useless slurry, little to the destruction and the disturbance of the soil body, little to the influence of construction of structures of top, cavern or periphery.
6, the interpolation core is convenient.
Level of the present invention can be applied to the construction of anchor pole to the job practices of cement mixing method, also can be applied to horizontal cavern excavation supporting.
