Further, described composite earth impervious body is mutually twisted for several composite earth stakes and is formed by stacking.
Further, described composite earth stake is sodio swelled ground and original soil body is uniformly mixed merely by stirring and forms, and its infiltration coefficient reaches 10-6Cm/s to 10-7Cm/s, and intensity is not less than original soil body.
Further, described composite earth impervious body is that several composite earth stakes are constituted, and is engaged 100-200mm between adjacent two composite earth stakes.
Further, described composite earth impervious body, to arrange along ground-connecting-wall wall thickness direction, at least two row's composite earth stake outside ground-connecting-wall wall, ground-connecting-wall is at least one row's composite earth stake within the walls；Described composite earth impervious body is along the deep direction of ground-connecting-wall wall, with the scope of at least 7m under hole at the bottom of self-conductance wall；Described composite earth impervious body is along ground-connecting-wall axis direction, at seam both sides more than the extension 1m of ground-connecting-wall.
Relative to prior art, the construction method of ground-connecting-wall flexible barrier body structure described in the utility model has the advantage that
(1) ground-connecting-wall flexible barrier body structure described in the utility model, impervious body therein is flexible, modulus is less than soil cement modulus, when ground-connecting-wall stress is deformed, impervious body fits tightly body of wall, can deform with body of wall, it is to avoid occur that the cement earth pile of rigidity or rotary churning pile produce gap when deformation of wall between piling wall, cause the phenomenon of seepage.
(2) ground-connecting-wall flexible barrier body structure described in the utility model, owing to this impervious body is composite earth stake, and is mutually twisted and is formed by stacking, make impervious body have and more closely prevent seepage, convenient construction, and simple in construction saves the advantages such as cost.
(3) ground-connecting-wall flexible barrier body structure described in the utility model; it is performed before ground-connecting-wall is constructed; ground-connecting-wall is constructed in impervious body; body of wall seam is wrapped up by impervious body completely; even if occur body of wall seam crossing folder mud or be commonly called as open underpants phenomenon; but because the seam crossing of wall is in impervious body, there is the protection of impervious body, it is possible to effectively avoid the seepage that this kind of constructional deficiency produces.

Describe this utility model below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
A kind of ground-connecting-wall flexible barrier body structure, the seaming position place between adjacent two width ground-connecting-walls surrounds composite earth impervious body, and wall 2 direct construction in composite earth impervious body after composite earth impervious body is initially formed of leading of ground-connecting-wall seaming position is offered.
Described composite earth impervious body 1 is mutually twisted for several composite earth stakes and is formed by stacking.Described composite earth stake is sodio swelled ground and original soil body is uniformly mixed merely by stirring and forms, and its infiltration coefficient reaches 10-6Cm/s to 10-7Cm/s, and intensity is not less than original soil body, but lower than the intensity of ground-connecting-wall body of wall.
This utility model be on construction ground in, first perform flexible compound soil impervious body 1, it is arranged over leading wall 2 at flexible compound soil impervious body 1, last ground-connecting-wall 3 of constructing in composite earth impervious body 1, because the deformation of composite earth impervious body 1 with ground-connecting-wall 3 has good servo, solve the leakage problems of current ground-connecting-wall 3 seam.
Because composite earth impervious body 1 is in the space of relatively ground-connecting-wall 3 seam expanded range, the infiltration coefficient of soil is made to be reduced to 10-6Cm/s to 10-7Cm/s, so, when ground-connecting-wall 3 is constructed, though occur body of wall seam crossing folder mud or be commonly called as open underpants phenomenon, but because the seam crossing of wall is in composite earth impervious body 1, have the protection of composite earth impervious body 1, it is possible to effectively avoid the seepage that this kind of constructional deficiency produces.
Owing to this composite earth impervious body 1 is composite earth stake, modulus is less than soil cement modulus, when ground-connecting-wall 3 stress is deformed, composite earth impervious body 1 fits tightly body of wall, can deform with body of wall, the cement earth pile or the rotary churning pile that avoid the occurrence of rigidity produce gap when deformation of wall between piling wall, cause the phenomenon of seepage.
Specific embodiment:
Surveying and locating, in place yet to be built, according to design drawing unwrapping wire, it is determined that ground-connecting-wall axis and each groove fragment position.According to soil property situation, set Irrigation Pressure, promote the construction parameters such as speed, utilize rig to spray in soil by sodium bentonite, and stir with original soil body, form composite earth stake.At ground-connecting-wall seaming position, the thickness direction along wall performs the composite earth stake being mutually twisted, and is engaged 100-200mm between two, to form the composite earth impervious body of flexibility.The boundary of works area of composite earth impervious body: along ground-connecting-wall axis direction, seam both sides extension 1m；Along wall thickness direction, outer 2 campsheds of wall, 1 campshed within the walls；Along the deep direction of wall, self-conductance wall 2 end, is with depth bounds no less than 7m (or with geological condition adjustment) beneath down to hole.Can adopt at composite earth impervious body position and change after wall 2 is led in the method process filling out compacting because of the original soil body of composite earth impervious body construction disturbance.Soil impervious body to be composite can carry out ground-connecting-wall construction according to a conventional method after having constructed 10 days in this position.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
