Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.
[0031] Such as Figure 1 to Figure 3 Shown, a kind of air bubble mixed light soil construction technology, comprises the following steps:
[0032] a. Excavate the base 1 and tamp it. The side of the base 1 is stepped. When digging, it is necessary to excavate the original drainage rapids. At this time, it is necessary to drain the rainwater on the road surface. A waterproof strip is repaired with cement mortar on the hard shoulder to divert the rainwater from the road to the rap...

Abstract
The invention discloses a bubble mixed light soil construction process which comprises the following steps of a, excavating a base, and tamping the base; b, paving gravels on the base to form a cushion layer; c, arranging a plurality of positioning pieces, wherein each positioning piece comprises a positioning nail and a body, the body comprises a positioning block and the reinforcing steel bars,the reinforcing steel bars are connected with and are arranged on the positioning blocks in a petal-shaped arrangement mode, and the positioning nails sequentially penetrate through the positioning blocks and the cushion layer from top to bottom and then are inserted into the base; and d, pouring the foam light soil to form a surface layer, wherein the positioning pieces are submerged in the surface layer. Compared with the prior art, the compression and defoaming of the bubbles are reduced by reducing the flowing of the foam light soil during the pouring process, and therefore it can be guaranteed that the volume weight is close to the design index as much as possible during the actual construction.
Description
technical field [0001] The invention relates to a construction technology of air bubble mixed light soil, in particular to a construction technology of air bubble mixed light soil. Background technique [0002] Bubble mixed lightweight soil is a new type of environmentally friendly material, which is used to solve the problem of car jumping in soft foundation embankments of high-grade highways, soft soil foundation treatment, differential settlement of new and old roadbeds when highway roadbeds are widened, and stability of high-fill embankments , saving land resources and other worldwide problems provide an excellent technical means and have good promotion value. However, the use of the existing air-concrete construction technology will easily lead to a large difference between the bulk density and the design index. In view of this, the inventor obtained a construction technique of air-bubble mixed light soil after in-depth research. Contents of the invention [0003] T...
