Abstract
The invention relates to a construction method for a multi-platform deep foundation of a hillside high-rise building. A plurality of construction platforms are formed through scaffolds which are erected along a slope, so that a plurality of platform pile holes can be simultaneously dug; and therefore, the coherence of construction steps is enhanced, the construction time is saved, and the construction efficiency is increased. The method is suitable for constructing the deep foundation of the high-rise building at hillside.
Description
Technical field
The present invention relates to a kind of foundation construction method, particularly a kind of foundation construction method of building the high-rise building of slope in.
Background technology
For the construction of the multi-platform deep foundation of hillside fields high-rise building, traditional elder generation high sequence of construction efficient in low back is low, can't satisfy construction period.Because when reality is excavated, if adopt sequence of excavation in the past, earlier low foundation construction, low foundation structure, lower waterproof, backfill, back eminence foundation construction, the eminence structure, procedure connection property is poor, long construction period.
Summary of the invention
The purpose of this invention is to provide the multi-platform deep foundation job practices of a kind of hillside fields high-rise building, solve tradition and build long construction period in the Tall Building Foundation construction, the technical problem of procedure connection property difference in the hillside fields.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The multi-platform deep foundation job practices of a kind of hillside fields high-rise building, step is following:
Step 6, colligation hole digging pile reinforcing bar, supporting template and concreting in the stake hole;
Step 7, treat the pile foundation concrete setting after, backfill between pile foundation.
Said step 4, the step of setting up of scaffold is: (A) leveling compacting bottom flat field place; (B) fill up chock on the ground in the flat field field of leveling compacting; (C) according to design pitch upright vertical rod on chock; (D) in the position apart from flat field place 0.2m, vertical posts is provided with one and encloses the bar of sweeping the floor; (E) along the highly parallel bar of sweeping the floor of vertical rod horizon bar is set at interval, the bar of finally sweeping the floor, horizon bar and vertical rod form scaffold frame; (F) in scaffold frame vertical and horizontal side bridging is set all; (G) safe blanket net is installed on the scaffold below operation layer is walked guidance tape; (H) with the scaffold of shoveling operating platform flush position on completely spread operation layer and walk guidance tape; (I) foot guard plate is set continuously around the layer of corridor; (J) the operation layer altitude range outside completely hangs Dense mesh screen.
In the said step 5, carry out following operation before the excavation of stake hole: the stake excavation that (a) makes an experiment, survey to checking the accuracy of report; (b) survey report, on-the-spot actual geological condition and the requirement of rigidity angle with combining, carry out absolute altitude calculating at the bottom of the stake of hole; (c) combine test pile, survey report and carry out absolute altitude correction at the bottom of the stake of hole.
Compared with prior art the present invention has following characteristics and beneficial effect:
The present invention is through setting up scaffold according to the slope; For multi-platform excavation simultaneously provides the excavation scope of operation; Can realize excavating the stake of hole, many places simultaneously, and in time the soil body transported through the scaffold operation layer, guarantee working security, operability, can satisfy construction period simultaneously, raised the efficiency.
The present invention has excavated construction simultaneously through multi-platform, has avoided traditional hillside fields poor from construct the one by one procedure connection that causes of lower to eminence, and the defective of long construction period has improved efficiency of construction.
The present invention through test pile excavation, hole stake at the bottom of absolute altitude calculate, revise, carry out the stake of multi-platform hole and excavate simultaneously thereby excavate the condition created simultaneously for multi-platform stake hole, guaranteeing to raise the efficiency the reduction of erection time greatly under working security, the operability prerequisite.
The present invention can be widely used in hillside fields highrise building deep foundation construction.
