Problems solved by technology
[0004] It solves the defects of inconvenient mechanized construction and low operating efficiency existing in the existing rubble masonry technology. The invention uses natural stones without particle size requirements for stacking and molding, can widely use local materials, greatly reduces the cost of masonry, and can be operated on site. It is simple and convenient for mechanical construction, not only has high working efficiency, but also the interlocking of rockfill skeletons improves the compressive and shearing strength of masonry

Embodiment 1
[0032] A rapid construction method of a meal masonry, including the following steps:
[0033] (1) Formulating a template having a certain stiffness and strength in the stiffness of the masonry structure; the stiffness and strength are sufficient to support the natural stone subsequent filled self-dense mortar is not deformized;
[0034] (2) Stack natural stone in the finished masonry template;
[0035] (3) Fill the prepared self-sufficient mortar to the natural stone gap in the template; the water ash than 0.975 in the dense mortar, the gray bit ratio is 0.27, and the fineness modulus of sand is less than 2.9;
[0036] (4) Self-constructing mortar over time, it will fill the styled shape. When the masonry reaches a certain strength, the template is removed, and the tight masonry is obtained from the dense mortar.
Embodiment 2
[0038] A rapid construction method of landscape masonry, including the following steps:
[0039] (1) Formulating a template having a certain stiffness and strength in the stiffness of the masonry structure; the stiffness and strength are sufficient to support the natural stone subsequent filled self-dense mortar is not deformized;
[0040] (2) Place an airbag mold on the inner side of the template, and does not inflate the airbag mold, the airbag mold is flat;
[0041] (3) Stacked natural stone in the finished masonry template; then inflated into the airbag mold, the thickness of the airbag mold is 1 / 3 to 1 / 2 of the minimum stone particle diameter, and no more than 10cm, 5cm Best; the pressure P> dam, ρ after the airbag mold is inflated, and the G is the gravity acceleration, H is the masonry once filling height;
[0042] (4) Filling the prepared self-sufficient mortar to the natural stone gap in the template; the water as ambient than 0.975, the grasted ratio is 0.27, and the fin...
Embodiment 3
[0045] Unlike Example 2, the thickness of the airbag mold was 10 cm.

Abstract
The invention relates to the technical field of building construction methods, in particular to a rapid construction method for rubble masonry, using templates to construct the shape, stacking natural stones in the templates, filling the gaps between the natural stones with self-compacting mortar, and using self-compacting mortar Remove the formwork after setting the shape, and then get the rubble masonry; when the exposed surface of the masonry requires a three-dimensional landscape effect of uneven stone materials, an airbag mold is lined inside the formwork that needs to be exposed. After the airbag mold is removed, the surface of the masonry is uneven. The stone surface has a good landscape effect. The masonry built by this method has no requirement on the particle size of the stone, and can make full use of local natural stone. It has the advantages of simple construction technology, fast construction speed, low cost, and strong three-dimensional effect on the exposed surface, which can not only meet the higher masonry strength. , and has a good landscape effect. At the same time, this technology can be widely used in masonry retaining walls, embankment slope protection, flood control and tide protection bank protection, masonry dams and dam shell protection, etc.
Description
Technical field [0001] The present invention relates to the technical field of building construction methods, and in particular, there is a rapid construction method of a meal masonry. Background technique [0002] At present, in addition to the masonry structure intensity and stability in my country, in addition to the masonry structure strength and stability, many applications must meet the visual landscape requirements of the outer road. The masonry method of the mastite structure in my country has used the form of artificial masonry. The artificial masonry requires stone size of the stone, which is not less than 20cm. There is a slow speed, the mortar is full, the intensity is low, and the strength is low. The shortcomings of low performance. In particular, a pulp stone with a surface of the convex concave stereoscopic landscape is usually used in the form of artificial shaping or in the form of stone bonding in thick layer mortar surface. This construction method has a stric...
