Abstract
The invention belongs to the construction of pile foundation in civil building field.Existing pile sinking method is difficult to enter firm hard formation, though the auger boring method for making pile by grouting into can enter firm hard formation, and the cost height.The invention provides a kind of pile forming method by hole-leading pulp pressing pilesinking, it is to take out a core less than the stake footpath in being difficult to the pile sinking ground in advance, is pressed into special slurries retaining wall simultaneously, through squeezing into pile sinking or vibration sinking tube along foramen primum to depth desired perfusion pile.This law has that the hole of drawing is fast, hole wall is stable, and characteristics such as ground extruding effect, easy construction are arranged at the bottom of the oppose side wall stake, construction area is little, pile capacity is high, cost is low can be widely used in the various pile foundation constructions that are difficult to the pile sinking stratum.
Description
The invention belongs to the construction of pile foundation in civil building field.
At present, because particularly export-oriented economy develop rapidly of national economy, tall and big heavy dark the increasing of great load building that reach, the control of massif stability of slope, hydraulic engineering, harbour, the development of industry such as road and rail abutment and civil engineering construction, prior art adopts direct pile sinking, the piling method, for the excessive stratum of formation resistance, can't construct, so the employing auger boring method for making pile by grouting into that has recently carries out pile foundation construction to it, this method can make pile foundation enter firm hard formation, but the no sand cement slurry that its mud jacking is to use, invalid cement loss amount is big, and do not have the compacted effect of tamping, so the low construction cost height of pile intensity.
For overcoming the shortcoming of prior art, the invention provides a kind of pile forming method by hole-leading pulp pressing pilesinking (being called for short the HKZ method).
This auger boring method for making pile by grouting into is characterized in that, it is promptly to draw the hole with the core that auger takes out less than the stake hole, be pressed into special slurries retaining wall with slush pump through the augers centre bore simultaneously, mobile rig mast aligns a pipe to draw position, hole vibration sinking tube perfusion pile.
In auger boring method for making pile by grouting into of the present invention, described mud jacking liquid can be that bentonite slurry, clay mortar, cement paste, cement add coal ash pulp and chemical grout, and wherein best is bentonite slurry.
In auger boring method for making pile by grouting into of the present invention, describedly be pressed into special slurries retaining wall from centre bore, its mud jacking apical side height generally is meant the degree of depth in groundwater table or the unlikely hole of collapsing.
In auger boring method for making pile by grouting into of the present invention, the hole facility that draw that described core drilling is used are augers, and preferably long screw auger also can be Churn drill, common abrasion drill, perhaps draws the hole with mode of jet.
The present invention since adopted draw the hole, the pile sinking method of mud jacking retaining wall and vibration sinking tube perfusion pile when drawing the hole, and the three combined, make construction method of the present invention demonstrate unique superiority that its bearing capacity of pile foundation height, cost reduce significantly.
The construction equipment that pile forming method by hole-leading pulp pressing pilesinking of the present invention adopts is the dual-purpose stake of a spiral mud jacking vibration sinking tube machine, sees accompanying drawing 1.When drawing hole mud jacking pile sinking bore forming, it is promptly to draw the hole with the core that long-armed auger (2) at first takes out less than the stake hole, use stock pump (5) mud jacking to be pressed into special slurries retaining wall simultaneously through the augers centre bore, roach and drill bit are proposed, movable mast (1) pours into pile with vibropile pipe (7) along the foramen primum vibration sinking tube.Draw bore open and draw the smaller the betterly deeply, the pressure 200～2000KPa of mud jacking generally determines by the test of local geological conditions.
Realize that best method of the present invention is to do by the operation instruction of accompanying drawing 1.Draw the hole separately as the also available any hole machinery that draws that do not satisfy the requirements, with slurry weight equilibrium method retaining wall, pile sinking gets final product fast.But time-consuming, no crushing.
The hole mud jacking pile sinking bore forming method of drawing of the present invention, in the past few years, through Beijing, many places, ground large-scale petroleum chemical engineering and Other Engineering test piles such as Tianjin, Shandong, Henan, Hebei, Inner Mongol, generally reflection is good, currently gains great popularity more.
For example: the 140000 tons of ethylene projects in Central Plains have adopted pile forming method by hole-leading pulp pressing pilesinking and bored pile method; The 300000 tons of chemical fertilizer engineerings in Central Plains have adopted draws the hole and squeezes into formula preformed pile method; Puyang steam power plant engineering has adopted the auger boring method for making pile by grouting into.
Economic technology contrast about this law and above-mentioned three kinds of prior art "forming columns sees Table four kinds of stake types of 1 Puyang "forming column economic technology comparison sheet:
Annotate: 1. this table cost is according to Henan Province's construction work quota of budgetary estimate in 1989, calculates in conjunction with the concrete condition of Puyang.
2. various stake type "forming columns all are not considered to power factor (PF).
To sum up, compared with prior art, the advantage of pile forming method by hole-leading pulp pressing pilesinking of the present invention is:
This law has the firm hard formation of breaking through difficult construction, be not subjected to Effect of Underground Water Level, it is fast to have the hole of drawing, hole wall is stable, oppose side wall has compacted, to the tamping reinforcement effect is arranged at the bottom of the stake, easy construction, the construction occupied ground is little, the bearing capacity of stake is the highest, and the cost decrease can be widely used in various tall and big heavy dark pile engineering and the controls of massif stability of slope that reach the building of great load, hydraulic engineering, harbour, the pile engineering of the abutment of highway and railway and other industry and civil buildings, but adopt this law accelerating construction progress, greatly save construction costs, economic benefit is very considerable, is rated as current ideal pile foundation pile sinking pile-making method.
