Abstract
The invention relates to a building material, particularly a pipeline engineering trench backfill material cement all-in-one mixture and a preparation method thereof. The mixture is mainly composed of a construction waste crushed mixture and soil and also composed of a small amount of cement as an auxiliary material, wherein the cement accounts for 3-10% of the mixture, the soil accounts for 35-45% of the mixture, the plasticity index of the soil is 10-20, and the water accounts for 10-16% of the mixture. The mixture has favorable workability, so such backfill mode can not leave dead corners at the pipeline axil angles, and the mixture can uniformly and compactly fill every corner and is safe and reliable. Compared with the traditional construction technique, the construction technique provided by the invention saves abundant human resources and material resources, greatly shortens the construction period, and is very worthy of popularization. In the aspect of material composition, the construction waste is utilized and changed into valuable substances to regenerate value, thereby implementing the ideas of energy saving and environment-friendly production.
Description
(1) technical field
The present invention relates to material of construction, be specifically related to a kind of pipework trench backfill material cement and close compound and preparation method more.
(2) background technology
The municipal pipeline engineering trench backfill material of China is generally element soil at present, dirt, yellow ground, stone flour and aggregate chips be mix by a certain percentage, cement, stone flour and aggregate chips be mix, broken (gravel) stone of grating and cement stabilizing broken (gravel) stone material etc. by a certain percentage, most compacting or rolling methods of adopting, this back-filling way exists a problem for a long time always, be that place, pipeline armpit angle is not difficult to grinding compacting or compacting because ballast consolidating machine has enough working faces, backfilling material degree of compactness does not reach design requirements, and voidage is larger.Due to the outside seepage of water in the immersion of surface water and the activity of underground water and pipeline or underground structure, cause producing to contact between backfilling material and pipeline or structures washing away, the fine grained soil in backfill soil is moved with the activity of underground water.Along with passing and the loss of underground fine grained soil, soil is emptied, and underground meeting produces cavity, and the situation that pipeline can be subjected to displacement in space, causes ground to subside, and people's life security is impacted.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, provide a kind of pipework trench backfill material cement to close compound and preparation method more, because the use of this compound can not be subjected to displacement pipeline in groove, thereby avoid the generation of surface collapse, safe and reliable.
The present invention is achieved through the following technical solutions:
A kind of pipework trench backfill material cement closes compound more, its special character is: it is main composition material that this compound be take construction waste crushing compound and soil, and be aided with a small amount of cement, cement accounts for the 3%-10% of compound total amount, soil accounts for the 35%-45% of compound total amount, this native plasticity index is 10-20, and its amount of water accounts for the 10%-16% of compound.
The preparation method that pipework trench backfill material cement closes compound more, comprises the following steps:
(1) selection: take construction waste crushing compound and soil as main composition material, and be aided with a small amount of cement, cement accounts for the 3%-10% of compound total amount;
(2) blunge: soil accounts for the 35%-45% of compound total amount, this native plasticity index is 10-20, according to the plasticity index of soil used, instructs amount of water, its amount of water accounts for the 10%-16% of compound, forms the good mixture of a kind of workability;
(3) pipeline backfill: in pipeline backfill construction, the good mixture of mixing is poured directly in backfill groove, is vibrated again floating with vibrating spear.
Beneficial effect of the present invention: because this compound has good workability, so this back-filling way can not leave dead angle at place, pipeline armpit angle, can fill uniformly densely each corner, safe and reliable; The ring stiffness that can increase backfill pipeline after this compound generation intensity, forms with it an integral body, has increased the intensity weather resistance of pipeline; For zanjon place etc. be inconvenient to down workman and mechanical backfill position especially applicable; This construction technology has been saved a large amount of manpower and materials than traditional construction technology, greatly shortens the construction period, is worthy to be popularized very much; Aspect material composition, we have used building waste, and these wastes are turned waste into wealth, and again produce and are worth, and have realized save energy, environmental protection production theory.
(4) accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of pipework groove of the present invention.
