Abstract
The present invention proposes the Sandwich biscuit type curtain water stop construction method of a kind of diaphragm wall, before guide wall of underground continuous wall is constructed, first lead, inside and outside foundation ditch, three axes agitating pile of constructing respectively outside wall, deeply following 3 5m at the bottom of stake deep entrance foundation ditch, wall hanging curtain is led in formation, then carries out trenching construction.Foundation ditch of the present invention forms both sides Sandwich biscuit type curtain, foundation ditch is wrapped in both sides and can effectively prevent infiltration, then carry out trenching construction, it is ensured that quality of wall and foundation ditch are internal water-tight.
Description
Technical field
The present invention relates to the realm of building construction, more particularly to the Sandwich biscuit type curtain water stop of a kind of diaphragm wall
Construction method.
Background technology
New World center three, the Wuhan phase office building project that New World Development (Wuhan) company limited plans to build, is by one 37
The comprehensive office building of five layers of annex composition of layer high building and floor height 68 meters.Construction area 140,000, below ground sets four layers of ground
Lower room, excavation of foundation pit area 13240, excavation of foundation pit degree of depth 21m 27m (" cheating in hole " 27m).
Foundation ditch surrounding enviroment are the severeest, complicated: north side is positioned at liberates business district, main road, next-door neighbour aviation road viaduct (and
Foundation ditch limit is distributed various pipe network facilities and box culvert)；Next-door neighbour foundation ditch southern side and west side _ _ _ _ _ have many 58 floor natural foundation,
Dilapidated house of the remote past；Deep basal pit stratum upper part is furnished with thickness compared with current-formed silt layer big, that intensity is low and silt clay
Soft Soil Layer, middle part is layer of sand and boulder bed, and the underlying stratum degree of depth reaches more than 55 meters.And the groundwater run off of this foundation ditch enriches, with
The Changjiang river communicates, and the substrate of this foundation ditch enters layer of sand, it is necessary to take sealing and deep-well draining, precipitation treatment measures.
In this project practice of construction operation process, it is necessary to diaphram wall of constructing around foundation ditch, yet with this base
There is abundant water resource bottom hole, thus directly implement diaphragm wall structure, easily cause seepage, affecting diaphragm wall shapes, sternly
The foundation pit side-wall that also can affect the end, hole more than of weight leaks.
Summary of the invention
In order to solve the problems referred to above, the present invention proposes the Sandwich biscuit type curtain water stop construction method of a kind of diaphragm wall,
By using the curtain water stop of Sandwich biscuit type to construct, three axes agitating pile of constructing in the both sides of diaphragm wall foundation ditch, stake deep entrance base
Deeply following 3 5m in the end, hole, are formed and lead wall hanging curtain, then carry out trenching construction, it is ensured that quality of wall and foundation ditch are internal water-tight.
The technical scheme is that and be achieved in that:
The Sandwich biscuit type curtain water stop construction method of a kind of diaphragm wall, before guide wall of underground continuous wall is constructed, first at base
Leading, inside and outside hole, three axes agitating pile of constructing respectively outside wall, at the bottom of stake deep entrance foundation ditch, deeply following 3 5m, are formed and lead wall hanging
Curtain, then carry out trenching construction.
Preferably, at least 1 row's three axes agitating pile of constructing inside foundation ditch, at least 2 row's three axes agitating pile of constructing outside foundation ditch.
Preferably, described three axes agitating pile three becomes the distance of overlap joint between a group, and adjacent two groups to be less than every
Radius.
Preferably, every diameter 600mm of described three axes agitating pile, often overlap between the group adjacent stake of three axes agitating pile away from
From for 150mm, between adjacent two groups, the distance of overlap joint is 300mm.
Preferably, every diameter 850mm of described three axes agitating pile, often overlap between the group adjacent stake of three axes agitating pile away from
From for 150mm, between adjacent two groups, the distance of overlap joint is 300mm.
Preferably, the distance at two row's three axes agitating pile centers of foundation ditch homonymy is 400mm.
What the present invention produced has the beneficial effect that this method easy construction, and the suitability is strong, and three axes agitating pile forms sandwich biscuit
The curtain water stop form of formula, at the bottom of stake deep entrance foundation ditch, deeply following 3 5m, are formed and lead wall hanging curtain, then carry out trenching construction, it is ensured that
Quality of wall and foundation ditch are internal water-tight.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the Construction Principle schematic diagram of the present invention；
Fig. 2 is that three axes agitating pile connects rows of schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The Sandwich biscuit type curtain water stop construction method of a kind of diaphragm wall, constructs at guide wall of underground continuous wall
Before, first lead, inside and outside foundation ditch 1, three axes agitating pile 2 of constructing respectively outside wall, deeply following 3 5m at the bottom of stake deep entrance foundation ditch,
Wall hanging curtain is led in formation, then carries out trenching construction.
Such as every diameter 850mm or 600mm of three axes agitating pile in embodiment in Fig. 2, the program uses and adopts inside foundation ditch
Using single three axes agitating pile, arrange two row's three axes agitating pile outside foundation ditch, the distance at two row's three axes agitating pile centers is 400mm,
Can be the most stranded, prevent percolating water.Between the stake that often group three axes agitating pile is adjacent, overlap distance is 150mm, first constructs
The partial distance intersecting overlap joint between the three axes agitating pile 22 of three axes agitating pile 21 and rear construction is 300mm, it is ensured that often organize stake it
Between overlap joint reliability.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
