Wash apron anti-settling anti-cracking construction method and structure

Abstract

The invention discloses a wash apron anti-settling anti-cracking construction method and a structure. The construction method comprises the following steps: firstly adding a geotextile layer on the upper surface of a 3-7 lime earth layer, then pouring a first layer of concrete wash apron; arranging an olecranon-shaped groove on the outer edge of the first layer of concrete wash apron, arranging an adhesion agent layer on the surface of the first layer of concrete wash apron, then pouring a second layer of concrete wash apron, and an olecranon-shaped concrete cast-in-place belt; and at last arranging an alkali-resisting fiberglass gridding cloth layer under the surface of the second layer of concrete wash apron. The wash apron anti-settling anti-cracking construction method and structure can effectively prevent outdoor wash apron anti-settling anti-cracking construction method and structure from seeping in, cannot have frost crack during 8-10 years using period, is durable, and the service life can be 2-3 times of that of common wash apron. Labor power, material resources and financial resources input at later-stage maintenance are saved, economic benefit and social benefit are obvious, and popularization value is wide.

Description

technical field [0001] The invention relates to a construction method and a structure of loose water in collapsible loess areas, in particular to a construction method and structure of outdoor water scattering and anti-sinking and anti-cracking of a house construction project where the outdoor ground is not hardened. Background technique [0002] In collapsible loess areas, such as Qingyang City located in the Loess Plateau of Longdong, the loess is widely distributed and thick, and it is the main carrier of various buildings, roads and other structures. However, under the influence of negative temperature in the cold winter season, a considerable number of building water and ground and road surfaces swelled significantly. After repeated freeze-thaw cycles, the structure of the soil changed. The porosity of the soil samples increased after the freeze-thaw cycle compared with that before the freeze-thaw cycle. With the increase of the number of freeze-thaw cycles, the collaps...
