Description

Technical Field

[0001] This utility model belongs to the field of embankment slope technology, specifically relating to a green prefabricated flexible connection revetment frame suitable for embankment slopes. Background Technology

[0002] With the country's high-quality development and the continuous construction of industrial, civil, and infrastructure projects, numerous fill slopes are inevitably formed due to limitations in engineering geological conditions during construction. Human engineering activities have altered the stress conditions of slopes, weakening or even destabilizing them. Therefore, slope management is necessary to protect human life, property, and the ecological environment. Traditional fill slope management measures mainly employ anti-slide piles, anchor bolts (cables), retaining walls, slope mesh and shotcrete, and frame anchoring. The frame anchoring structure primarily consists of prestressed anchor bodies (anchor bolts, anchor cables) and concrete frame beams. Planting vegetation between the concrete frame beams can prevent erosion by rainwater and provide greenery. However, current concrete frame beams are all integrally cast, making them rigid designs. Uneven settlement of the frame beam revetment can lead to tensile cracking and damage; the skeleton revetment is also prone to detachment. Utility Model Content

[0003] This utility model provides a green prefabricated flexible connection revetment frame for embankment slope protection. It can solve the problem of the current slope protection frame cracking and failure due to uneven settlement on embankment slopes. The flexible connection avoids frame failure caused by uneven settlement and ensures the durability of slope support.

[0004] To achieve the above-mentioned technical objectives, this utility model provides a green prefabricated flexible connection revetment frame for backfill slopes. The revetment frame includes an outer frame beam formed by a top beam, a toe beam, and vertical beams. A slope protection structure composed of triangular hollow connectors and square hollow connectors is arranged inside the outer frame beam. The top beam, toe beam, and vertical beams are all reinforced concrete beams. The triangular hollow connectors and square hollow connectors are connected to each other, and the triangular hollow connectors and square hollow connectors are connected to the outer frame beams by chains.

[0006] The preferred technical solution of this utility model is as follows: the top beam, the toe beam, and the vertical beam are all equipped with steel cages, which are prefabricated by concrete pouring. The main bars of the steel cages extend beyond the top beam, the toe beam, and the vertical beams. The top beam, the toe beam, and the vertical beams are connected by the extended main bars and then fixed together by concrete pouring.

[0007] The preferred technical solution of this utility model is as follows: one side of each triangular hollow connector is connected to the top beam, bottom beam, or vertical beam via at least two sets of chains; the other two sides of the triangular hollow connector are connected to the square hollow connector via at least two sets of chains respectively; and adjacent square hollow connectors are connected by at least two sets of chains. First metal fixing rings are pre-embedded on the top beam, bottom beam, and vertical beam. Grooves are provided at the positions where the connecting chains of the triangular and square hollow connectors are located, and second metal fixing rings are pre-embedded in the grooves. The two ends of the chains connecting the triangular hollow connectors to the outer frame beam are welded to the first and second metal fixing rings respectively.

[0020] The specific construction process of the green prefabricated flexible connection revetment frame for the backfill slope in the embodiment is as follows:

[0021] S1. Pre-construction preparations include cleaning debris from the slope surface within the slope support area, re-measuring the slope topographic line, marking the construction boundary line, positioning lines for the slope top beam, slope toe beam, and vertical beam, and preparing materials and construction equipment.

[0022] S2. Lay the top beam 1, toe beam 5, and vertical beam 3. All three beams are reinforced concrete structures with internal steel reinforcement cages, precast by concrete pouring. The main reinforcement bars of the cages extend outwards and are laid along the positioning lines during installation. The top beam 1, toe beam 5, and vertical beam 3 are connected by these extended main reinforcement bars and then fixed together by concrete pouring. Figure 1 As shown; and when pouring the top beam 1, the toe beam 5 and the vertical beam 3, the first metal fixing ring 7 is pre-embedded in the designed position; the side of the top beam 1 with the first metal fixing ring 7 is placed below the slope direction, the side of the toe beam with the first metal fixing ring 7 is placed above the slope direction, and the two vertical beams 3 are provided with the first metal fixing ring 7 symmetrically placed on both sides in the direction perpendicular to the slope, so as to facilitate connection with other precast components.

[0023] S3. Laying Connectors: Triangular hollow connectors 2 have pre-set second metal fixing rings 9 on three sides. One side is fixed to the top beam 1 via a chain 6.
