Problems solved by technology

[0002] At present, the construction of the lime-soil cushion mainly uses a small amount of elevation control piles. After the lime-soil is transported and paved, a level is used to measure and recheck the elevation, and the elevation is then trimmed. The pre-control measures for the quality of the lime-soil cushion layer and the protection of the finished product are not detailed enough. , did not form a detailed systematic advanced technical construction method and pre-control method
It is easy to cause a decline in the quality of the lime soil cushion and produce some common quality problems

Embodiment Construction

[0009] 1. The average distance between the length and width direction of the foundation pit at each step of lime soil laying is nailed into the elevation pile. When wooden piles are used, the pile top elevation is 10mm lower than the predetermined virtual soil elevation. Small nails are driven into the pile top, and the nail cap elevation is the first layer of lime soil The elevation control line will be popped up around the pit wall, and the line rope will be hung on the elevation pile at the paving site (when wooden piles are used, the small nails on the top of the pile) at the paving site before the lime soil is paved. The elevation control lines around the walls are used to control the elevation of the virtual paving of lime and soil.

[0010] 2 Use sifted lime-soil materials that are uniformly stirred according to the design ratio.

[0011] 3 The first step is to transport the lime soil in the pit: the lime soil is transported and laid by the strip jumping grid method, th...

Abstract

The invention discloses a strip-type inter-grating construction method for spreading a lime-loess cushion, which can improve construction process level and quality level and belongs to the technical field of building construction. In the construction method, the construction technologies of pile arrangement and line hanging at equal distance, strip-type inter-grating transportation spreading, long bar leveling broom sweeping grain and mechanical and compact rolling compaction after completely spreading in each step are adopted, and the elevation control to the lime-loess cushion, surface course evenness control and the precontrol of finished product protection and the like are carried out, therefore, the quality level is obviously improved, and the quality confidence level on a construction unit is improved by a construction unit. After loosened soil is spread, the surface course is even without any footprint trace. The invention eliminates the common quality failings, such as inaccurate elevation, uneven surface course, poor finished product protection and the like in the lime-loess cushion construction.

Description

Technical field [0001] The invention belongs to a construction technology method in the construction field, and relates to a method for improving the construction technology level and construction quality level of a lime-soil cushion layer. In particular, the method invention can improve the accurate elevation, smooth surface and finished product protection ability of the lime-soil virtual soil surface layer. Background technique [0002] At present, the construction of the lime-soil cushion mainly uses a small amount of elevation control piles. After the lime-soil is transported and paved, a level is used to measure and recheck the elevation, and the elevation is then trimmed. The pre-control measures for the quality of the lime-soil cushion layer and the protection of the finished product are not detailed enough. , No detailed systematic and advanced technical construction methods and pre-control methods have been formed. It is easy to cause a decline in the quality of th...
