(2), churning or high-pressure injected water mud in end occlusion is formed between described box-shaped steel plate wall occlusion chamber, thus form box-shaped steel plate occlusion diaphragm wall;
(3), along with the excavation of foundation ditch, as required several is set from top to down in described box-shaped steel plate wall foundation ditch side and encloses purlin;
(4) enclose purlin, to be engaged diaphragm wall with box-shaped steel plate and to be connected by connector;
(5), box-shaped steel plate wall pass through described in enclose purlin and be connected with the inner supporting structure in foundation ditch;
(6), along with the construction of basement structure, from bottom to up, in batches temporary support is set between box-shaped steel plate occlusion diaphragm wall and outer wall of basement, and remove respective range inner support, enclose purlin and connector thereof, complete support replacement;
(7), whole basement construction is engaged backfill between diaphragm wall and outer wall of basement at described box-shaped steel plate after completing, and removes temporary support;
(8), the more described box-shaped steel plate occlusion diaphragm wall punching method that shakes is extracted from the soil body after backfill completes.
Also include step (9), strict place is required to horizontal deformation of soil body at worked, while extracting box-shaped steel plate diaphragm wall, need high-pressure injected water mud.
Describedly enclose purlin and inner support is the steel beam column that H-shaped, pipe, rectangular tube, angle steel or channel-section steel are made.
Described temporary support is the steel beam column that H-shaped, pipe, rectangular tube, angle steel or channel-section steel are made.
Beneficial effect of the present invention is mainly manifested in: 1, foundation depth is unrestricted, applied widely; 2, be not easy to leak; 3, easy to connect with inner support; 4, space enclosing structure does not need reinforcing bar and concrete; 5, construct easy to make, safe and reliable; 6, can repeatedly huge profit use, cost is extremely low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, and the present embodiment is implemented under premised on technical solution of the present invention, but protection scope of the present invention is not limited to following embodiment.
Embodiment one:
With reference to accompanying drawing 1-12, box-shaped steel plate wall 1, to be welded 2 chamber bodies of wall by weld seam 7 by 5 block plates 2; Pipe sub-buckle 3 and open-end tube box 4 are established in described box-shaped steel plate diaphragm wall termination; Two circular holes 5 are established at described box-shaped steel plate diaphragm wall top, and reinforce with four blocks of steel loop plates 6; In the soil body 7 of leading wall 8 certain depths, adopt three axes agitating pile machine to stir, high pressure injection clear water, makes the described scope soil body be flow-like simultaneously, forms the soil body 9; Described box-shaped steel plate wall is inserted in fluidised form soil; Churning or high-pressure injected water mud 10 in the occlusion chamber that end occlusion is formed between described box-shaped steel plate wall, form box-shaped steel plate occlusion diaphragm wall; Along with the excavation of foundation ditch, first is set and encloses purlin 11, described in enclose purlin and be engaged between diaphragm wall with box-shaped steel plate and be connected by steel plate 12 and angle steel 12a; The described purlin that encloses is connected with first steel inner support 13,14; Purlin and inner support is enclosed by same sequence construction second; After shoveling completes, construction basement bottom board 15, concrete slab 16 and exterior wall 17, floor 18 and other structural element, and interim crossbeam 19 is set, strut 20 and connector 21,21a, that removes the horizontal inner support of second and correspondence position thereof encloses purlin and connector; Complete first time support replacement; Carry out second time support replacement in the same way; After basement completion, between described box-shaped steel plate occlusion diaphragm wall and outer wall of basement, the soil body backfills, and from bottom to up, when being backfilled to shoveing position, removes shoveing 19,20 and connector 21,21a; After backfill completes, more described box-shaped steel plate is engaged diaphragm wall by circular hole 5, with shaking, punching method is extracted from the soil body.
