Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a construction method for clear-water concrete pouring in municipal engineering, which solves the problem that the internal material of the concrete is too single, and there are no other additives, resulting in cracks and other situations after the concrete is poured in the later stage. Appears, it is easy to cause the wall rigidity is not strong, the accident of collapse occurs in the later stage, causing more serious losses

Embodiment 1

[0027] S1. Prepare containers and devices: pre-clean multiple storage barrels, prepare stirring devices, grinders, vibrators, measuring rulers, levels and wooden trowels;

[0028] S2. Formwork production: use a grinder to grind the outer surfaces of multiple sub-formworks and rigid rods in advance. After the grinding is completed, wipe them clean with a rag, and weld multiple rigid rods with a quantitative width of 2cm on the outer surfaces of the sub-formworks. And the outer surface of the steel rod is pre-smeared with 1cm quantitative thickness of cement paint. After the application is completed, place it for 10 minutes, then apply 1cm quantitative thickness of anti-rust grease on the outer surface, and then place it for 10 minutes, and then pass the external measuring ruler and level. The sub-formwork with steel rods welded on the outer surface is assembled;

[0029] S3. Concrete preparation: prepare in advance 100 parts of water, 10 parts of admixture, 300 parts of sand, 2...

[0034] S1. Prepare containers and devices: pre-clean multiple storage barrels, prepare stirring devices, grinders, vibrators, measuring rulers, levels and wooden trowels;

[0035]S2. Formwork production: Use a grinder to grind the outer surfaces of multiple sub-formworks and rigid rods in advance. After the grinding is completed, wipe them clean with a rag, and weld multiple rigid rods with a quantitative width of 3cm on the outer surfaces of the sub-formworks. And the outer surface of the steel rod is pre-smeared with 1.5cm quantitative thickness of cement paint. After the application is completed, let it sit for 15 minutes, then apply 1.5cm quantitative thickness of anti-rust grease on the outer surface, and then leave it for 15 minutes, and then pass the external measuring ruler and level. , assemble the sub-formwork with steel rods welded on the outer surface;

Abstract

The invention discloses a municipal engineering fair-faced concrete pouring construction method, and relates to the technical field of construction engineering. The municipal engineering fair-faced concrete pouring construction method includes the following steps: S1, container and device preparation; S2, formwork manufacturing; S3, concrete preparation; S4, transportation treatment; S5, pouring treatment; and S6, trowelling treatment. According to the method, by adding multiple groups of materials to concrete, the concrete can have higher strength and higher environmental friendliness and resist alkali corrosion, and thus a solidified wall has higher strength and better airtightness; and by directly using an external vibrating rod to vibrate the concrete and pouring the concrete layer bylayer, air contained in the concrete can completely escape, the situation of large inside and outside temperature difference after concrete setting is avoided, the situation that surface sinking occurs during concrete setting and causes parting is effectively prevented, and thus the concrete pouring effect is better.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a pouring construction method of fair-faced concrete for municipal engineering. Background technique [0002] With the development of the construction industry, the country is vigorously promoting the construction of ecological civilization, and people's awareness of environmental protection has increased. Surface-effect concrete is a new type of green, high-performance concrete that integrates structure and decoration. The fair-faced concrete structure is no longer used for external decoration, which saves external decoration materials, which is very important for saving natural resources and reducing engineering costs. Significance, the development of clear-water concrete construction technology in China started much later than other countries. By the 1970s, clear-water concrete was mainly used in the prefabricated clear-water concrete wall panels in the constr...
