Description
Technical field
The invention belongs to pipe lubricants when concrete pumping technique field more particularly to a kind of concrete pumping.
Background technique
Concrete generallys use pump and is pumped when pouring, when concrete flows in pipeline with tube contacts friction
It is larger, so that concrete is poor in pump line pipeline internal mobility, it is difficult to predetermined position is pumped into rapidly, and once for a long time, so that pipe
Road inner wall hangs with a large amount of concrete, further influences the speed and fluency of concrete pumping.Therefore, in practical engineering application
In, mostly use the mode of mortar profit pipe to come so that concrete flows rate of pumping faster in pipeline, current lubricant is main
Composition is concentrated using polyacrylamide, cellulose ether, hydrophilic surfactant, proportion is according to various brands on the market
From the point of view of it is different but all not good enough in terms of the pumping lubrication of concrete, it is difficult to meet growing pumping demand, it is especially difficult
To adapt to the higher and higher engineering construction demand of delivery position.
Summary of the invention

When being lubricated the preparation of agent by said ratio, the ingredient obtained in above-mentioned each embodiment is carried out at the scene
Even mixing, it is preferable that first polyacrylamide, hydroxyethylmethylcellulose are put into and place into lauric alcohol sulfuric acid after mixing evenly
Sodium must gradually to pour into clear water while stirring and be dissolved when being again stirring for uniform, and it is mixed to be eventually adding pentane asphaltenes
It closes uniformly, the water temperature of the clear water should be maintained at 26~32 DEG C.Above each embodiment is also added with and causes in specific preparation
Agent and defoaming agent promote lubricant properties, and it is respectively 1% and 1.5% that additive amount is calculated by percentage to the quality.
Field test is carried out for the lubricant of above each embodiment preparation, installation (is adopted in 15 degree herein diagonally downward
Pumped with day) several pump lines, pump tube length is respectively 30 meters, 50 meters, 80 meters, 120 meters of four kinds of length specifications, and corresponding
Several pipelines of tetra- kinds of caliber specifications of DN80, DN100, DN125, DN150 before the test will be residual in each section of delivery pump pipe
Slag removal is clean, and noresidue is cleaned in pump line and is dried, and when delivering concrete, lubricant is respectively taken appropriate respectively along pump truck hopper
Inner wall is poured slowly into hopper so that lubricant uniformly flows into pump line inner wall of the pipe along hopper, then start slowly to
It is put into concrete in hopper, pressurization pumping can be started when concrete covers the feed inlet of pump.Specific test parameters and
Its effect see the table below, wherein caliber is diameter (unit mm), and pipe range unit is rice, and lubricant additive amount is KG, general lubricant
Representative existing Rett Lai Hunningturun pipe agent can be used:
Table 1.
The experimental data of above-mentioned table 1 is analyzed it is found that being added in overwhelming majority test by proportion system documented by the present invention
At lubricant after increase the rate of pumping of concrete, the test result data of small part are less than existing general lubrication
The rate of pumping of agent, it may be possible to caused by some accidentalia, but can not cover above-mentioned beneficial caused by the present invention
Effect；More preferably moistened it is found that can be obtained using lubricant provided by the invention than general lubricant according to above-mentioned experimental data
Effect is slided, so that resistance is smaller between the concrete and tube wall in pipeline, flow velocity faster, greatly improves pumping efficiency, so that mixed
Solidifying soil is transported to the predetermined area much sooner, and knows to reach optimum efficiency when matching used by embodiment 15.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
