Embodiment Construction

[0035] like Figure 1-Figure 3 As shown, a construction method for prestressed anchoring reinforced concrete panels of slopes, including the following steps:

[0036] (1) During construction, the slope should be overcut by 500mm-1000mm, preferably 500mm.

[0037] (2) Carry out drilling at the design position of the slope body, and put the steel strand 1 into the hole, and carry out the grouting operation;

[0038] (3) When the slurry in the hole reaches the specified strength, start the construction of the concrete panel, lay double-layer steel mesh 3 on the inclined surface of the slope wall, and nail the angle steel 7 vertically into the slope body at intervals on the slope wall In the rock formation, the angle steel 7 is used for the internal support of the formwork 5, and remains in the concrete panel after the concrete 4 is poured.

[0039] After the angle steel 7 is nailed into the rock formation of the inclined surface of the slope body and fixed, the length of the an...

Abstract

The invention discloses a construction method for a reinforced concrete panel for prestress anchoring of a slope and a formwork forming structure of the concrete panel. The method comprises the following steps that firstly, during construction, the slope is subjected to overexcavation by 500 mm-1,000 mm; secondly, the designed position of a slope body is drilled, a steel strand is placed in a hole, and grouting operation is conducted; thirdly, when grout in the hole reaches the regulated strength, a double-layer reinforcing mesh is laid on a slope wall, and angle iron is vertically nailed in a slope body rock stratum on the slope wall every other certain distance; fourthly, a formwork is laid at the end portions of extension sections of the angle iron, and beams used for supporting the angle iron are arranged on the upper side and the lower side of the formwork; and fifthly, box iron used for external supporting is arranged on the outer side of the formwork, and an anchorage device is used for locking the steel strand penetrating the formwork and fixed to the box iron. According to the construction method for the reinforced concrete panel for prestress anchoring of the slope and the formwork forming structure of the concrete panel, a brand new construction method for the reinforced concrete panel for prestress anchoring of the slope is provided, construction is fast and convenient, safety and stability are achieved, the manufacturing cost is saved, and the advantage that construction materials are used from local materials is sufficiently utilized.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, and is particularly suitable for a construction method for prestressed anchoring reinforced concrete panels of slopes and a formwork forming structure for concrete panels. Background technique [0002] At present, in geotechnical anchoring projects, the general construction methods are different, or the construction is cumbersome, or the safety degree after construction is not enough, and there is no fast, convenient, safe and stable construction method. In addition, the example of using prestressed anchor cables for anchoring is relatively long, but it does not meet the specification requirements of regular construction. Therefore, designing a fast and safe construction method and structure has become an urgent problem to be solved. Contents of the invention [0003] In view of the above problems, the present invention researches and designs a construction method for prestressed anchori...
