InactiveCN106614207AEffective protectionLow priceClimate change adaptationPisciculture and aquariaWaste tiresWorking hours
The invention discloses an anchorage foundation formed by three groups of annular waste tires and steel piles. The anchorage foundation comprises annular waste tire weight balancing blocks, steel piles and a connecting bracket, the connecting bracket comprises a base plate, three connecting plates distributed at intervals are arranged on the outer edge of the base plate, a hanging ring is arranged on the upper end face of the base plate, the upper end face of each connecting plate is provided with a casing pipe and a sleeve, the sleeves are located on the outer side, and construction holes are formed in the upper portions of the casing pipes; during working hours, each steel pile is sleeved with the corresponding sleeve for fixation, an anchor chain is tied and fixed to the hanging ring, construction auxiliary iron wires are tied to the construction holes, the connecting bracket is put into sea to make contact with a seabed, the three casing pipes are sleeved with the annular waste tire weight balancing blocks on the basis of the construction auxiliary iron wires, and the weight balancing blocks press the connecting bracket and press the steel piles into the seabed to form the net cage anchorage foundation; construction is completed through the steps of sinking point positioning, waste tire weight balancing block sinking, anchorage foundation posture checking and the like. The anchorage foundation is easy to manufacture and convenient to construct, and has economy and practicability.

Large cantilever structure suitable for broadening old road of cliff road section and construction method
PendingCN111254772ASolve technical problems that cannot be implementedAvoid safety hazardsRoadwaysSewerage structuresPile capArchitectural engineering
The invention relates to a large cantilever structure suitable for broadening an old road of a cliff road section. The large cantilever structure comprises an old road, a lower side slope cliff and anupper side slope cliff, and the lower side slope cliff and the upper side slope cliff are located on two sides of the old road respectively. A strip-shaped foundation, uplift piles and pile caps arearranged on the old road, the strip-shaped foundation is arranged close to the lower side slope cliff and in the length direction of the old road, the uplift piles are arranged close to the upper sideslope cliff, and the pile caps are arranged on the uplift piles; prefabricated cross beams are arranged on the old road, the prefabricated cross beams are arranged on the strip-shaped foundation andthe pile caps, and the bottoms of the prefabricated cross beams are partially embedded in the old road. Compared with the prior art, the large cantilever structure has the advantages of wide application range, safety construction, avoidance of potential safety hazards during construction, convenient and quick construction, high safety and reliability, smooth drainage, easachievement accessibilityand maintenance, and full-life design.
