Construction method of uplift pressure resisting concrete protection slab

Abstract

The invention discloses a construction method of an uplift pressure resisting concrete protection slab. The construction method comprises the following construction steps of a, construction measuringlofting, b, base cleaning, c, foundation tamping and cushion layer replacing, d, cushion layer face protection, e, prefabricated concrete protection slab paving and splicing, f, pile screwing, and g,surface and joint water stopping. By means of the construction method of the uplift pressure resisting concrete protection slab, the function of uplift pressure resistance of the concrete protection slab can be effectively improved, the conditions that the concrete protection slab is cracked, fractured and the like due to the insufficient protection slab strength, wave impact, cushion layer blockstone movement, soil sedimentation and the like are effectively prevented, and the service life of the concrete protection slab is prolonged.

Description

technical field [0001] The invention belongs to the field of building structure construction, and relates to a construction method of a concrete protective panel for resisting buoyancy force. Background technique [0002] In order to prevent external loads such as water flow from scouring the slope, it is usually necessary to protect the slope. At present, the commonly used armor structures mainly include dry block stones, mortar block stones, concrete armor panels and special-shaped artificial armor panels using breakwaters. Concrete armor panels are the most economical method in areas lacking stone materials. [0003] The existing concrete panels are mainly used to prevent surface water erosion and seepage, but under the joint action of waves, water flow, and groundwater, the concrete panels are under pressure in two directions, downward and upward, especially under the action of buoyancy force. In the next step, the concrete panel becomes unstable, which usually manifest...

Problems solved by technology

[0003] The existing concrete panels are mainly used to prevent surface water erosion and seepage, but under the joint action of waves, water flow, and groundwater, the concrete panels are under pressure in two directions, downward and upward, especially under the action of the buoyancy force. In the next step, the concrete panel becomes unstable, which usually manifests as the panel moves upward or rotates as a whole, which eventually leads to problems such as cracks and fractures in the concrete panel
