Fig. 2 be the adjacent high low layer of basement according to embodiments of the present invention (across) the schematic diagram of reverse construction method.
Detailed description of the invention
Describe below with reference to the accompanying drawings the adjacent high low layer of basement of the present invention (across) the embodiment of reverse construction method.Those of ordinary skill in the art will be consequently realised that, when without departing from the spirit and scope of the present invention, it is possible to various different modes or its combination, described embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than are used for limiting scope of the claims.Additionally, in this manual, accompanying drawing draws not in scale, and identical accompanying drawing labelling represents identical part.
In construction, " high low layer " refers to the different floor of building, and " high-low bay " refers to different absolute altitudes on the same layer.Such as, some local is built across floor, such as hall, auditorium.The reverse construction method of the present invention had both been suitable for basement height low layer and also had been adapted for high-low bay construction.
According to an aspect of the present invention, it is provided that a kind of adjacent high low layer of basement (across) reverse construction method, this reverse construction method is compared with conventional method, by building stock mould by laying bricks or stones, changes sequence of construction, it is possible to be efficiently completed construction operation.Its sequence of steps is followed successively by:
S1, along high low layer (across) boundary alignment high-rise (across) district puts slope excavation；
S2, after excavation, by high-rise for the outside alignment of boundary to be built body of wall (across) distance of a mobile waterproof layer and waterproofing protection layer thickness, form stock mould sideline, build stock mould by laying bricks or stones along stock mould sideline；
S3, after stock mould is built by laying bricks or stones, junctional area put slope excavation part high level (across) side, backfill cyclopean concrete；
S4, cyclopean concrete backfill after, stock mould low layer (across) side carry out waterproof construction, when waterproof construction it is noted that waterproofing node is carried out detailed treatment；
S5, after waterproof construction, carry out low layer (across) sole plate construction；
S6, boundary body of wall and high-rise (across) sole plate pouring construction simultaneously.
And the construction procedure order of routine is followed successively by:
S1 ', along high low layer (across) boundary alignment high-rise (across) district puts slope excavation, and carries out slope retaining；
S5 ', carry out low layer (across) sole plate construction；
S6 ', carries out boundary wall construction；
S4 ', handing-over metope high level (across) side carry out waterproof construction；
S3 ', put slope excavation part high level (across) side, backfill cyclopean concrete；
S6, carry out high level (across) the construction of sole plate.
In this reverse construction method build by laying bricks or stones stock mould, backfill cyclopean concrete, waterproof and protective layer low layer (across) earth excavation, clear groove, bed course, anchor pole, waterproof and protective layer construction period can construct simultaneously; and high-rise (across) sole plate and boundary body of wall construct simultaneously; effectively saved boundary wall to have constructed the engineering time of waterproof and protective layer, backfill cyclopean concrete beyond the wall of boundary of constructing again, saved cyclopean concrete backfilled high level of constructing again (across) time of sole plate.
This construction method can greatly shorten the total lever factor of engineering.Decrease boundary wall and high level (across) expense of the steel plate for sealing water at construction joint place between sole plate, reduce construction cost.
In one alternate embodiment, waterproof construction includes:
S41, stock mould low layer (across) side carry out water-proof leveling construction；
S42, after completing the construction of water-proof leveling layer, carries out construction of waterproof layer on water-proof leveling layer, and alternatively, waterproof layer adopts macromolecule intersection film water-proofing material, it would however also be possible to employ other waterproof materials；
S43, after completing construction of waterproof layer, carries out fish tail and waterproof layer construction, and alternatively, fish tail and waterproof layer adopts extruded polystyrene board.
This construction method is described in detail below with Qingdao number matchmaker's center projects, this project overall floorage 360,000, it is divided into 6 construction units.Wherein, 1#-5# building basement is three layers, and basis end absolute altitude is-8.05 meters, 6# building basement is two-layer, and basis end absolute altitude is-4.40 meters, and the basement in 6 buildings is connected, there is high low layer in the basement intersection in Ze 6# building and other each buildings, and there is boundary exterior wall basement connection.
Conventional sequence of construction is carry out the slope retaining of interface after earth excavation, as it is shown in figure 1, adopt anchor pole to carry out slope retaining.Then carry out the construction of negative three layers sole plate 2, then carry out the construction of boundary body of wall 3.In FIG, the right side of body of wall 3 is the indoor of negative three layers, and the left side of body of wall 3 is the wall face of negative three layers.After wall construction completes, start to be sequentially carried out from inside to outside the construction of mortar levelling layer 6, external wall waterproof layer 5, fish tail and waterproof layer 4 from wall face, finally carry out junctional area cyclopean concrete and be backfilled to negative two layers of bed course absolute altitude.Then the construction of the sole plate 7 of negative two layers can just be carried out.
