Description
Technical field
The utility model belongs to technical field of building construction, is specifically related to a kind of diaphragm wall and reinforces waterproof construction.
Background technology
Diaphragm wall has that the rigidity of structure is large, the feature of globality, impermeability and good endurance, can be used as permanent retaining soil and water and load-carrying members; Can adapt to construction environment and the hydrogeological conditions of various complexity, can construct near existing building, basic noiselessness, shockproof when construction is less on adjacent structure and underground utilities impact; Can build the subterranean wall of the various degree of depth, width and profile.Owing to thering is a series of advantage, so diaphragm wall obtains applying more and more widely in city underground and deep foundation engineering.
But, than the job site of comparatively dense, how under the prerequisite of guaranteeing surrounding buildings safety, to carry out the construction of diaphragm wall for building, be a stubborn problem; And if this builds than the job site underground water of comparatively dense compared with horn of plenty, also easily there is percolating water phenomenon in the body of wall of diaphragm wall so after soil excavation, the seam crossing of each groove section of diaphragm wall is the multiple position of seepage especially, if effectively prevention and control of wall leakage, can, to the safety of foundation ditch surrounding enviroment, even produce greatly harm to the safety of foundation ditch.Therefore how before soil excavation, to carry out the support reinforcement of diaphragm wall and waterproof only the work of oozing be to design and construct to make great efforts a difficult problem solving all the time.
Summary of the invention
The purpose of this utility model is to provide a kind of diaphragm wall and reinforces waterproof construction, and this support reinforcement waterproof construction has not only increased substantially the supporting effect of diaphragm wall, has also guaranteed that diaphragm wall has good sealing anti-seepage effect simultaneously.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of diaphragm wall is reinforced waterproof construction, this support reinforcement waterproof construction comprises support reinforcement section and reinforces waterproof section, and support reinforcement section arranges and overlaps along the body of wall length direction interval of diaphragm wall with reinforcing waterproof section;
Described support reinforcement section is arranged on the body of wall place that does not have jointed diaphragm wall, and support reinforcement section forms by being arranged on the single three axle agitation piles of diaphragm wall hole inner side and being arranged on the three axle agitation pile groups that three axle agitation piles of many rows parallel arrangement in outside, diaphragm wall hole form, and described single three axle agitation piles and three axle agitation pile groups are all extended continuously along the body of wall length direction of diaphragm wall;
Described reinforcing waterproof section is arranged on the seam crossing between the adjacent slot section of diaphragm wall, and reinforce waterproof section and comprise that being arranged on diaphragm wall cheats the single three axle agitation piles of inner side and be arranged on seam the high-pressure rotary jet grouting pile for sealing of cheating at least two parallel arrangements in outside, described reinforcing waterproof section also comprises sealing establishes at least one row three axle agitation piles that are overlapped on outside, high-pressure rotary jet grouting pile hole.
The utility model can also be able to further realization by following technical measures:
Preferably, the spacing between described single three axle agitation piles or three axle agitation pile groups and diaphragm wall body of wall is 10~20 centimetres; In described three axle agitation pile groups, the lap length between two row's three axle agitation piles adjacent one another are is not less than 10 centimetres.
Further, the lap length between described two row's three axle agitation piles adjacent one another are is 20 centimetres.
Preferably, the stake diameter of described each high-pressure rotary jet grouting pile is 800mm, the lap length of two adjacent high-pressure rotary jet grouting piles be at least single high-pressure rotary jet grouting pile stake diameter 1/4th, the lap length of high-pressure rotary jet grouting pile and diaphragm wall be at least single high-pressure rotary jet grouting pile diameter 1/4th.
The beneficial effects of the utility model are:
1), the utility model is by support reinforcement section and reinforce waterproof section and form, wherein support reinforcement section is arranged on the body of wall place that does not have jointed diaphragm wall, and reinforces waterproof Duan Ze and be arranged on the seam crossing of diaphragm wall.
Support reinforcement section is provided with single three axle agitation piles in the inner side, hole of diaphragm wall, and in the hole of diaphragm wall arranged outside double three axle agitation piles, wherein the stake top of double three axle agitation piles and the wall top of diaphragm wall are concordant, and the stake end of double three axle agitation piles reaches middle weathered layer; This design can effectively prevent the infiltration of caving in of soil at both sides and underground water in the time of continuous wall trench underground, guarantees the safety of construction of diaphragm wall stage surrounding enviroment.The i.e. three axle agitation piles formation water-stop curtain outside the hole of diaphragm wall of triaxial cement mixing pile simultaneously, and born part and kept off native function, increase the rigidity of diaphragm wall, play the effect of permanent gear soil and sealing.
Because the seam crossing of each groove section of diaphragm wall is the position occurred frequently and multiple of seepage, therefore the utility model in the hole of seam arranged outside the high-pressure rotary jet grouting pile for sealing of two parallel arrangements, be provided with again row's three axle agitation piles in the outside, hole of high-pressure rotary jet grouting pile simultaneously, thereby not only ensure the support reinforcement effect of the seam crossing of each groove section of diaphragm wall, also seal the infiltration path of seam crossing, guaranteed the sealing anti-seepage effect of seam crossing.
2), the utility model has adopted the combination three axle agitation pile structures of optimizing: the three axle agitation piles in outside, hole have the effect of gear soil, sealing, protection surrounding enviroment, rigidity is larger, and adopt double lattice layout, the stake top of three axle agitation piles is concordant with diaphragm wall, and the stake end of three axle agitation piles reaches middle weathered layer; Three axle agitation piles of inner side, hole only have the effect of the collapse hole of preventing, and must cut after construction of diaphragm wall completes, thereby are conventionally arranged as single stake, and by its long being controlled within the scope of the easy soil layers that collapse hole occurs such as fine sand layer.
3), combination three axle agitation piles and the high-pressure rotary jet grouting pile in the utility model is fitted to each other, take full advantage of the feature of agitation pile, reduce the security risk of foundation pit construction stage and operational phase, save to greatest extent again material simultaneously, reduce the cost of supporting, can be widely used in that the excavation of foundation pit degree of depth is large, the Diaphragm Wall Support Structure of geological conditions and surrounding enviroment complexity.
