Description
Technical field
The present invention relates to a kind of construction method of basement, particularly a kind of construction method of cancelling the outer facade operating walk way of basement.
Background technology
Along with the continuous minimizing of land resources, improving constantly of Building technology, the height of building construction and the degree of depth are all constantly to aerial and underground development, the height of building is repaiied higher and higher, the degree of depth of basement is also repaiied darker and darker, for solving usable floor area or the few earth and stone digging amount of saving the area, expand basement, save unnecessary expense.
The traditional construction method of basement mainly comprises the following steps: (1) construction hollows out stake or castinplace pile; (2) earth and stone digging, on the basal plane after excavation, concrete base layer 2 is sprayed in construction; (3) construction basement bottom board pea gravel concreten layer 9; (4) the basement bottom board leveling layer 10 of constructing on pea gravel concreten layer 9; (5) the basement base plate waterproofing 11 of constructing on basement bottom board leveling layer 10, the outer facade waterproof layer 6 of basement surrounding constructs on interim brick body protection wall 4; (6) construction basement bottom board fish tail and waterproof layer 12; (7) lay basement bottom board reinforcing bar; (8) build basement bottom board concrete (containing basement basis girth pedestal foot steel concrete) and complete basement bottom board 13; (9) lay the outer facade of basement and floor steel bar, outer facade stays the operating walk way 3 of 0.6 meter-1.5 meters, guarantees that the waterproof of outdoor facade under construction ground and other engineering are used; (10) build the concrete of the outer facade of basement and basement flooring, complete the outer vertical plane wall 8 of basement; (11) remove basement inner and outer template; (12) while removing concreting, be used for the waterproof drawhead of fixed form; (13) outside basement in vertical plane wall 8 construction outside facade leveling layer 7; (14) the outer facade waterproof layer 6 of construction on facade leveling layer 7 outside; (15) the outer facade waterproof topping 5 of construction; (16) construction outer wall facade brick body protection wall 4; (17) remove the outer facade frame pipe of basement; (18) earthwork of backfilling operation passage 3.Adopt the basement structure of traditional construction method construction as shown in Figure 1.
As from the foregoing, in the traditional construction method of basement, be provided with the operating walk way of 0.6 meter-1.5 meters for the outer facade of basement, thereby convenient, to guarantee outdoor facade under construction ground waterproof and other engineering, finally also need like this operations such as backfill that this operating walk way is carried out cubic metre of earth in construction, not only increased the operation of construction, increased construction cost and construction working amount, and the space of this operating walk way is wasted, reduce the usable floor area of basement.
Summary of the invention
The object of this invention is to provide one can cancel traditional basement construction method China and foreign countries facade and must leave operating walk way; guarantee waterproof and the impregnable new technology of other engineering of outdoor facade under construction ground simultaneously; adopt the minimum cubic metre of earth and stone that can expand the soil utilization of 0.6 meter of-1.5 meters of basement girth or excavate less 0.6 meter of-1.5 meters of basement girth of the method, descend frugally the unnecessary expenses such as chamber base girth pedestal foot steel concrete, the outer facade leveling layer of basement, fish tail and waterproof layer, brick body protection wall, exterior sheathing, outrigger pipe, the backfill earthwork.
Technical scheme of the present invention is achieved in that a kind of construction method of cancelling the outer facade operating walk way of basement, it is characterized in that: comprise the following steps:

(2) earth and stone digging, sprayed mortar basic unit on the basal plane after excavation, and facade waterproof layer outside directly constructing in sprayed mortar basic unit;
(3) construction basement bottom board pea gravel concreten layer, directly magma levelling on described pea gravel concreten layer;
(4) construction basement base plate waterproofing, whole basementwaterproofing all completes;
(5) construction basement bottom board fish tail and waterproof layer;
(6) lay basement bottom board reinforcing bar;
(7) build basement bottom board concrete;
(8) lay the outer facade of basement and floor steel bar, the outer facade of basement does not stay operating walk way;
(9) build the concrete of the outer facade of basement and basement flooring;
(10) remove basement inner formword and frame pipe, basement engineering civil engineering part completes substantially.
The construction method of the outer facade operating walk way of cancellation basement of the present invention, in step described in it (2), the thickness of sprayed mortar basic unit is 3～10cm.
The construction method of the outer facade operating walk way of cancellation basement of the present invention, in step described in it (5), basement bottom board fish tail and waterproof layer is the 1:2 cement mortar of thickness 2cm.
The construction method of the outer facade operating walk way of cancellation basement of the present invention, described in it, outer facade waterproof layer and basement bottom board waterproofing course adopt coating class waterproofing materials.
The construction method of the outer facade operating walk way of cancellation basement of the present invention, described in it, outer facade waterproof layer and basement bottom board waterproofing course adopt coiled material class waterproofing materials.
The present invention directly constructs outer facade waterproof layer in the basic unit of the sprayed mortar after excavation in step (2), after waterproofing course completion, the outer facade waterproof topping of 1:2 cement mortar that the 2cm that no longer constructs is thick, build after completion at basement bottom board, can directly outer basement vertical plane wall be cast in the sprayed mortar basic unit of the waterproofing course of having constructed, so cancel in conventional construction method the requirement that external facade stays operating walk way, make the soil utilization of its minimum 0.6-1.5 of expansion rice basement girth or dig less the cubic metre of earth and stone of 0.6 meter of-1.5 meters of basement girth, descend frugally chamber base girth pedestal foot steel concrete, the outer facade leveling layer of basement, outer facade waterproof topping, brick body protection wall, exterior sheathing, outrigger pipe, the unnecessary expenses such as the backfill earthwork.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
