Embodiment

[0050] On-site construction steps:

[0051] Binding of the main reinforcement of the slope slab first;

[0052] Position and set out the reinforced concrete slab with a width of 100mm;

[0053] To install reinforced concrete slab reinforcement, first install the vertical main reinforcement Φ10@200, and then bind the horizontal reinforcement 6Φ10;

[0054] Supporting reinforced concrete slab formwork for ramps and curbs (spending formwork construction);

[0055] Positioning and laying out of the foundation of the ramp and the corner of the ramp and supporting the formwork (formwork hanging construction);

[0056] Install the concrete chamfering mold of the road tooth foundation;

[0057] Carry out the concrete pouring of the main structure of the slope slab, and then immediately carry out the foundation pouring of the corbels separated by the road; then pour the reinforced concrete slabs of the curbs separated by the road;

[0058] Carry out the demolition of the foundation f...

Abstract

The invention belongs to the technical field of curb construction, and particularly relates to a one-time pouring construction process for a ramp double-lane separation curb and a main body structure.The process comprises the following steps of S1, binding reinforcing steel bars of an inclined plate main body structure according to a traditional construction process; S2, when a fourth joint is constructed, installing embedded parts, and when a fifth joint is constructed, binding the reinforcing steel bars; S3, erecting a ramp separation curb template; S4, mounting a separation curb concrete chamfering mold; S5, carrying out concrete pouring on a ramp inclined plate main body structure, and carrying out ramp separation curb concrete pouring immediately after pouring; and S6, when the fourth joint is constructed, installing a finished shading plate, and when the fifth joint is constructed, smearing cement mortar for leveling and troweling. The method solves problems of a long construction period and difficulty in construction of the existing curb, and can be widely applied to construction of various pavements.

Description

technical field [0001] The invention belongs to the technical field of curb construction, and in particular relates to a one-time pouring construction process of curbs and a main structure of a ramp separated by two lanes. Background technique [0002] Flexible pavement curbs are constructed after the pavement base is completed and before the asphalt surface is paved; after paving the pavement base, the curbs can be planed along the sideline of the pavement and installed as a foundation; Widen the base of the pavement as the foundation; it can also use the excess part of the natural width on both sides of the base during the construction of the base of the pavement as the foundation, and the thickness and elevation of the foundation must meet the design requirements. After the center line of the measuring and laying-out line is checked, the curb floss is released at the junction of the edge of the road surface and the curb. The straight line part is 10m pile; the curve part ...
