Abstract
A kind of high intensity compresses prefabricated section backfilling process, by being mixed, stirring, compressing by conventional backfill, curing process obtains high intensity and compresses prefabricated section, further increase the intensity of backfill, eliminate building body sedimentation in advance to a greater extent, the bearing capacity of ground is improved, reduces construction cost, at the same time, the generation of building waste can be reduced, building waste is fully subjected to secondary use.
Description
Technical field
The present invention relates to technical field of building construction, and in particular to a kind of high intensity compresses prefabricated section backfilling process.
Background technology
In construction, it is necessary to return the soil tamped again, normally referred to as after the below ground engineerings such as basis are completed
" backfill ".At present, the quality of backfill is not generally high, easily causes the sinking at backfill position, causes many owners to think building body
Poor quality, there are serious quality problems, as specialty construction personnel, it is easy to be seen to be backfill and occur asking
Topic, is no any influence for building weight.
The content of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of high intensity compression prefabricated section backfilling process, can not only
The construction quality of engineering entirety is improved, reduces building body differential settlement, and reduces construction cost, is built meanwhile, it is capable to reduce
The generation of building refuse, fully carries out secondary use by building waste.
In order to solve the above technical problems, the technical solution that the present invention takes is：
The present invention proposes a kind of high intensity compression prefabricated section backfilling process, it is characterised in that comprises the following steps：
（1）Preloading block raw material are selected：Using backfill, building waste, cement, rubble, sand as preloading block raw material；
（2）The stirring of preloading block raw material：Backfill, building waste, cement, rubble, sand are put into mixer and add water
It is stirred, until stirring evenly；
（3）The compression of preloading block raw material, curing process：By step（2）The homogeneous mixture of generation is put into mould, passes through liquid
It is compressed by pressure device in the mold, is cured it, then carries out natural curing, and it is pre- to obtain high intensity compression
Clamp dog；
（4）Prefabricated section uses：To be carried out first in foundation trench it is levelling, then by step（3）Obtained high intensity compress prefabricated section into
Row is piled up.
Further, the cement is portland cement.
Further, the mould is plastic mould.
Further, in step（3）In, the natural curing keeps having in film solidifying by the way of plastic foil covering
Bear water.
Further, in step（4）In, when stacking, piles up in the way of one along a fourth.
Further, the backfill is dirt.
The present invention provides a kind of high intensity to compress prefabricated section backfilling process, by the way that conventional backfill is mixed,
Stirring, compression, curing process obtain high intensity compression prefabricated section, further increase the intensity of backfill, to a greater extent in advance
Building body sedimentation is first eliminated, the bearing capacity of ground is improved, reduces construction cost, meanwhile, it is capable to reduce the production of building waste
It is raw, building waste is fully subjected to secondary use.
