Abstract
The utility model discloses a piled raft foundation with improved foundation pit slopes, wherein pit walls are slopes, slope piles are arranged under the slopes, and the top ends of intersection positions between the slope piles and the slopes are respectively partially made into a small flat bottom. The piled raft foundation with the improved foundation pit slopes has the advantages that: 1, stressing of piles and rafts is facilitated; 2, a foundation pit does not need to be maintained, the construction is simple, and the manufacture cost is saved; 3, the waterproofing function of the top of each pile is the same as that of a common pile, and convenience and simplicity are realized; and 4, the piled raft foundation is suitable for all pile types.
Description
Technical field
the utility model relates to technical field of buildings, is specifically related to the foundation pile raft foundation of a kind of pile foundation+raft plate, the improved pile-raft foundation in particularly a kind of foundation ditch slope.
Background technology
The general base form that adopts pile foundation+raft plate in
high-rise especially super highrise building basis, because elevator foundation ditch and sump etc. will be set, raft plate part will fall low.Following two kinds of methods are arranged in the construction usually: 1, straight slope is made at the end, hole, two kinds of stake top mark high score height, and the stake top directly anchors into base plate, sees figure one; 2, the sloping is done at the end, hole, and stake top mark height is along ramp, and the stake top is cut into hypotenuse and is anchored into base plate, sees figure two.
these two kinds of ways all have tangible weak point: in the method 1, the raft plate is generally thicker, bear directly or indirectly effects such as integrally bending, local buckling, shearing, die-cut, relative settlement, and stressing conditions is comparatively complicated; Foundation ditch is made straight slope, and the raft plate thickness has sudden change, can produce stress and concentrate, and is stressed very unfavorable to the raft plate; In addition, foundation ditch border adjacent studs top mark height differs bigger, general 2m ~ 3.5m, and stake will be born the lateral shear effect of soil before underplate concrete is built; In addition, foundation ditch is made straight slope, during construction; To do upright hole wall and to go along with sb. to guard him, increase construction costs, and go along with sb. to guard him difficult.In the method 2, because the stake top will be cut into hypotenuse, to castinplace pile, the stake top is cut hypotenuse and can be realized, but for prefabricated tubular pile, difficulty of hypotenuse is cut on the stake top, and hypotenuse stake top waterproofing process is more difficult than general stake.
Summary of the invention
the utility model technical problem to be solved is to overcome the defective of the improved pile-raft foundation on the foundation ditch slope of prior art, a kind of construction costs is provided, goes along with sb. to guard him the improved pile-raft foundation in foundation ditch slope easily.
are in order to solve these problems of the prior art; The technical scheme that the utility model provides is: the improved pile-raft foundation in foundation ditch slope; The hole wall is the slope; Said slope has domatic stake, it is characterized in that, make in the part, top of the intersection on said domatic stake and slope one little flat.
preferably, the little flat area on said domatic stake top equals domatic stake cross-sectional area.
preferably, the little flat area on said domatic stake top is not less than domatic stake cross-sectional area.
preferably, the little flat of said domatic stake top extends 15cm length at least in the other direction again along foundation ditch.
preferably, little flat the interconnecting on adjacent domatic stake top constitutes the stepped layer aggregated(particle) structure.
Additional bar is preferably laid on the little flat and vertical plane on domatic stake top in
.
The advantage of the improvement pile-raft foundation on the foundation ditch slope of
the utility model is: 1. pair stake and raft plate are stressed favourable; 2. foundation ditch need not safeguarded, constructs simple and convenient and the saving cost, and 3. a top waterproof is with general stake; Simple and convenient, 4. be applicable to nearly all type.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the pile-raft foundation sketch map on the foundation ditch slope of prior art;
Fig. 2 is the pile-raft foundation sketch map on the foundation ditch slope of prior art;
Fig. 3 is the improvement pile-raft foundation sketch map on the foundation ditch slope of the utility model;
Fig. 4 is the improvement pile-raft foundation sketch map on the foundation ditch slope of the utility model.
Wherein, 1 is the excavation slope stake, and 11 is domatic stake, and 111 is the foundation ditch stake,
2 is the raft plate, and 3 is raft slab muscle, and 4 is additional bar,
5 are excavation slope, and 51 is the slope, and 52 is little flat, and 53 is foundation ditch.
The specific embodiment
further specify such scheme below in conjunction with specific embodiment.Should be understood that these embodiment are used to the utility model is described and the scope that is not limited to limit the utility model.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
embodiment such as Fig. 3, shown in Figure 4; The improved pile-raft foundation in foundation ditch slope, the hole wall is slope 51, said slope 51 has domatic stake 11; Make in the part, top of the intersection on said domatic stake 11 and slope 51 one little by flat 52; Little flat 52 areas on said domatic stake top equal the cross-sectional area of domatic stake 11, and in another preferred embodiment of the utility model, little flat 52 areas on domatic stake top are not less than domatic stake 11 cross-sectional areas; In another preferred embodiment of the utility model, little flat 52 of domatic stake 11 tops are extended 15cm length at least in the other direction again along foundation ditch.
are shown in Figure 4, and among the embodiment of the utility model, little flat 52 of adjacent domatic stake 11 tops interconnect and constitute the stepped layer aggregated(particle) structure.
are as shown in Figure 3, lay additional bar 4 on little flat 52 and the vertical plane on domatic stake 11 tops.
above advantage that shows and described basic principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.
