Description
Technical field
The present invention relates to the technical field of pattern foundation pit supporting structure, more particularly to the continuous three axes agitating pile water-stop curtain interplantation of foundation ditch
The construction method of support pile.
Background technology
In foundation pit supporting construction, the utilization of " retaining piles+water-stop curtain " is very universal, and conventional at present has following
Two kinds of forms, shown in reference picture 1, one kind is using the formation water-stop curtain of high-pressure rotary jet grouting pile 102 between retaining piles 101；Ginseng
According to shown in Fig. 2, another is using the deep-mixed pile or high-pressure rotary jet grouting pile 102 mutually overlapped in the outside of retaining piles 101
Form waterproof of man.
During practice of construction, because the water-stop curtain diameter of high-pressure rotary jet grouting pile 102, deep-mixed pile formation is small
(550mm-800mm), between stake in mutually overlap joint often, is influenceed easily to produce perpendicularity deviation greatly by formation, is caused
Not close, bifurcated is combined between water-stop curtain, causes occur underground water seepage in Excavation Process, water-stagnating effect is difficult to ensure that.
The content of the invention
It is an object of the invention to provide the construction method of the continuous three axes agitating pile water-stop curtain interplantation support pile of foundation ditch,
Aim to solve the problem that water-stop curtain of the prior art is not close in the presence of combining, cause occur underground water seepage in Excavation Process
And the problem of water-stagnating effect difference.
The present invention is achieved in that the construction method of the continuous three axes agitating pile water-stop curtain interplantation support pile of foundation ditch, bag
Include following construction procedure：
1), according to Foundation Pit Support Design, the groove of certain depth and width is excavated on the ground, is jumped in the groove
Mutually overlapped between the multiple three axes agitating piles of play construction, the adjacent three axes agitating pile, and multiple three axes agitating piles
It is in a row-shaped arrangement, form stirring row of piles；
2), constructed multiple support piles in the stirring row of piles, construction of multiple support piles along the stirring row of piles
Direction arranged for interval,；
3), in the top construction stake apical cap beam of the support pile, construction direction of the stake top Guan Liang along the support pile
It is disposed to extend；
4) bottom of foundation ditch, is excavated on ground, in the plain concrete surface layer of excavation face injection of the foundation ditch.
Further, the water barrier that the bottom of the three axes agitating pile enters below bottom of foundation ditch.
Further, in the construction procedure 1) before, first ground grading.
Further, after the mixing pile applies work completion about 5~7 days, by the three axes agitating pile for stirring row of piles
The stake of sequence of construction construction supporting.
Further, in the construction procedure 4) in, the supporting pile driving construction is completed after being no less than 15 days, carries out foundation ditch
Excavate, staged and layered is excavated to bottom of foundation ditch.
Further, in the construction procedure 4) in, in the middle of the plain concrete surface layer, add two-way concrete slab net.
Further, the Single Pile footpath of the three axes agitating pile is between 650mm-850mm.
Further, it is engaged between the stake of the adjacent three axes agitating pile between spacing 200mm-250mm.
Further, the stake footpath of the support pile is between 1000mm-1200mm.
Further, the spacing of the adjacent support pile is between 1500mm-1800mm.
The construction method for the continuous three axes agitating pile water-stop curtain interplantation support pile of foundation ditch that the present invention is provided, first constructs three
Axle mixing pile, forms and is mutually overlapped between stirring row of piles, three axes agitating pile, contrasts the mixing pile of identical stake footpath and spacing, identical
In water-stop curtain length, at least 2/3 overlap joint number of times is reduced, globality, the compactness of water-stop curtain is effectively ensured；In shape
Into stirring row of piles in construct the support pile separately arranged, can not only effectively prevent underground water seepage, water-stagnating effect is good,
And construction land need not be additionally taken, support pattern more optimizes, rationally.
