Abstract
The utility model relates to a T-shaped pile combined plank sinking pit bracing construction including a T-shaped pile, a precast slab and an anchor pulling structure. The outer side of the T-shaped pile is a proposed excavating pit. The precast slab is arranged in the inner side of the T-shaped section of the T-shaped pile. The lower end of the T-shaped pile is perpendicularly fixed in the soil mass and the upper end is stretched to a non-excavating part for fixing by means of the anchor pulling structure.
Description
Technical field
The utility model relates to the technology of a kind of pattern foundation pit supporting structure in the underground building construction, can effectively prevent foundation ditch periphery soil body seepage flow, landslide, landslide, thereby guarantee normally carrying out of underground structure construction.
Background technology
At present, in foundation pit supporting project, adopt put slope protection, soil nailing bolt support more, the higher foundation ditch of underground water level adopted the deep-mixed pile curtain more, Larsen steel sheet pile, open caisson etc.All be to construct safety, reliable by the designing unit's design of specialty and the construction team of specialty often than relatively large base pit engineering.Usually out in the cold for the foundation ditch of some more small-sized engineerings, just because of this, it often is exactly the foundation ditch of these more small-sized engineerings that the more foundation ditch of security incident takes place.If the common method that the pattern foundation pit supporting structure of these minor workss adopts large-scale foundation ditch to adopt will increase construction costs greatly.
Summary of the invention
Contradiction when overcoming above-mentioned minor works pattern foundation pit supporting structure between support pattern and the construction costs, the utility model provide a kind of T shape stake combination heavy plate foundation pit supporting construction, and simple in structure, easy construction, the construction period is short, cost is lower and safe and reliable.
The concrete technical scheme that realizes the utility model purpose is:
The heavy plate foundation pit supporting construction of a kind of T shape stake combination, comprise the stake of T shape, precast plate and draw anchor structure, this T shape stake outside is for intending excavation pit, and this precast plate is arranged on the inboard in this T shape stake T word cross section, this T shape stake lower end is vertically fixed in the soil body, and the upper end is drawn anchor structure to pull to non-excavation place with this and fixed.
This precast plate is the rectangle precast plate.
This T shape stake is the precast reinforced concrete piles of T font for the cross section.
This precast plate is prefabricated reinforced concrete hollowcore slab or the non-hollowcore slab of prefabricated reinforced concrete.
This draws anchor structure is to adopt steel concrete cast in situs to make, or adopts shaped steel, or adopts steel hinge line.
The beneficial effect of utility model is, and is simple in structure, and easy construction, cost are low, safe, reliable.
Description of drawings
Fig. 1 is the vertical view of the heavy plate foundation pit supporting construction of the utility model T shape stake combination;
Fig. 2 is the elevation of the heavy plate foundation pit supporting construction of the utility model T shape stake combination;
Fig. 3 is the lateral view of the heavy plate foundation pit supporting construction of the utility model T shape stake combination.
Description of reference numerals:
The stake of 1-T shape; The 2-precast plate; 3-draws anchor structure; The 4-foundation ditch.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical view of the heavy plate foundation pit supporting construction of the utility model T shape stake combination, as shown in Figure 1, the outside of T shape stake 1 is for intending excavation pit 4, and precast plate 2 rides over the inboard in the T word cross section of T shape stake 1, T shape stake 1 upper end is with drawing anchor structure 3 to pull to the soil body at non-excavation place, and anchoring is firm.It is the precast reinforced concrete piles of T font that this T shape stake 1 can be adopted the cross section.
Fig. 2 is the elevation of the heavy plate foundation pit supporting construction of the utility model T shape stake combination, and as shown in Figure 2, T shape stake 1 lower end is fixed on intends in the following soil body in excavation pit bottom surface, with drawing anchor structure 3 anchorages, prevents that structure from toppling on it.Drawing anchor structure 3 to adopt steel concrete cast in situs to make, also can be shaped steel or steel hinge line.
Fig. 3 is the lateral view of the heavy plate foundation pit supporting construction of the utility model T shape stake combination, as shown in Figure 3, precast plate 2 rides over the inboard, T word cross section of T shape stake 1, and T shape stake 1 lower end is vertically fixed in the following soil body of substrate, the upper end forms a firm supporting and protection structure by drawing anchor structure 3 anchorages.Precast plate 2 is the rectangle precast plate preferably, can be the prefabricated reinforced concrete hollowcore slab, also can be the non-hollowcore slab of prefabricated reinforced concrete.T shape stake 1, precast plate 2 and draw the parameters such as sectional dimension of anchor structure 3 to need according to factors such as foundation depth, soil property situation, foundation ditch surrounding enviroment definite after stressed accounting.
Comprehensively consult Fig. 1,2,3, before the excavation of foundation pit, the precalculated position is squeezed in T shape stake 1, T shape stake 1 upper end begins in T shape stake 1 outside to cut the earth with drawing anchor structure 3 anchorages then, and is more and more darker along with cutting the earth, precast plate 2 is put into the T word cross section inside top surface of T shape stake 1 from above, sink by the own wt block-by-block of precast plate 2, until digging to specifying absolute altitude, thereby form retaining wall one.The utility model is simple in structure, and easy construction, cost are low, safe, reliable.
More than be illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
