The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The utility model discloses a project of design structure closes on Zhao wang river to lotus zee seaport garden project, and this river groundwater is abundant, and the water level is higher, and this project foundation ditch degree of depth is about 7m, because of its ground is weak, still can't reach the side slope stability requirement according to the construction back scene of design paper requirement, need do the side slope earlier and strut.
Supporting construction mainly be applicable to the narrow and small side slope support form that adopts nature to put the slope in place, be particularly useful for richly and be difficult for under the weak soil layer ground condition that permeates water at water content.
As shown in fig. 1-2, a stay cable supporting structure comprises a supporting pile 1, a backing beam 2 and a knotting cable 3; many fender pile 1 paste in proper order and closely arrange and its lower extreme is executed to beat and is buried in foundation ditch bottom ground 7, and fender pile 1 is executed to beat after the location, sets up back backing crossbeam 2 in its one side towards the foundation ditch, and back backing crossbeam 2 is taut by drawknot cable 3 and makes its compress tightly in the one side of fender pile 1, and like this, fender pile 1 receives the pressure of back backing crossbeam 2 to make the back of fender pile 1 compress tightly in the foundation ditch lateral wall in order to prevent that the foundation ditch side from collapsing, eliminates the potential safety hazard.
In the embodiment, the support pile 1 adopts H-shaped steel which is easy to obtain in a construction site, the tying rope 3 adopts a steel cable meeting the strength requirement, after the H-shaped steel is applied, a part of a web plate of the H-shaped steel is perforated, one end of the steel cable penetrates through the H-shaped steel and is bound on the backing cross beam 2, and the tail end of the steel cable is bound and fixed on an existing firm building on a side slope or a self-arranged fixing component 6.
In order to sufficiently tighten the lashing wires 3 and reduce the number of the fixing members 6 to save construction costs, the two lashing wires 3 are fastened together to the fixing members 6 by tying the two lashing wires 3 together into one lashing wire 3 at a portion of the two lashing wires 3 near the slope in such a manner that one fixing member 6 is shared by every two lashing wires 3 (as shown in fig. 3). When the two lashing wires 3 are lashed together, various lashing structures can be adopted, for example, the lashing wires are tightened, a lashing sleeve, a lock catch and the like are adopted, and in the embodiment, the steel wire rope lock catch 4 is adopted.
In the embodiment, the backing beam 2 adopts a pipe bundle structure in a shape like a Chinese character 'pin' formed by tightly holding three steel pipes, so that the weight of the material can be reduced under the condition of meeting the strength, the steel pipes belong to construction foundation building materials, and the construction site materials are easily obtained.
In addition, the fixing member 6 includes embedded steel bars 61 and concrete piles 62, the concrete piles 62 are pre-cast in the slope foundation 8, the embedded steel bars 61 are pre-embedded in the concrete piles 62, the upper ends of the embedded steel bars 61 are provided with downward bent hooks, the lower ends of the hooks are embedded in the concrete piles 62, the upper ends of the hooks are exposed out of the concrete piles 62 to form a closed annular exposed elbow 611, so that the binding ropes 3 can be conveniently bound, and meanwhile, in order to enable the embedded steel bars 61 to be better positioned in the concrete piles 62, the lower ends of the embedded steel bars 61 are provided with reinforcing hooks 612.
The lashing wire 3 is fastened to the exposed bends 611 of the fixing members 6, and in order to enhance the stability of the connection and to uniformly distribute the tension of the lashing wire 3 to the respective fixing members 6, an auxiliary rod 5 is provided, the auxiliary rod 5 penetrates through the exposed bends 611 of all the fixing members 6, and the lashing wire 3 is simultaneously fastened to the exposed bends 611 and the auxiliary rod 5 (as shown in fig. 4).
It can be seen that the upper end of the support pile 1 is tied through the steel cable, and the H-shaped steel does not adopt an occlusion driving method, so that the number of the H-shaped steel can be saved, and the support cost is reduced; high-cost profile steel support occlusion driving is avoided, and project cost is effectively saved.
The utility model can be widely used for side slope support with narrow site and natural slope; the method is particularly suitable for limiting the displacement and deformation of the support pile 1 under the condition of a soft soil layer foundation which is rich in water content and not easy to permeate water. Because the H-shaped steel is applied and driven into the soft foundation, the embedding of the base part of the H-shaped steel is unstable, even if the buried depth of the H-shaped steel is increased, the deformation of the H-shaped steel cannot be avoided, the stress generated by the deformation and displacement of the H-shaped steel is transmitted to the fixed component 6 through the steel cable so as to achieve the constraint of the support pile 1, the deformation development generated by the soft foundation is eliminated, the safety of the side slope can be effectively guaranteed, the supporting quality of the side slope is guaranteed, and the potential safety hazard is eliminated. The construction is simple and the use is easy, and the method can be used for similar engineering reference in the future.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
