Description

The repeatable grouting test system in interior and Seed harvest radius measuring method
Technical field
The invention belongs to geotechnical engineering technical field of experiment equipment, it is related to a kind of indoor repeatable grouting test system and knot Stone body radius measuring method.
Background technique
It often cuts into a mountain in the early stage construction of Mountainous City valley-fill, forms the soil-rock mixture back filled region of large area, buried depth From several meters to rice up to a hundred etc..With the acceleration of urbanization expansion and urbanization process, Metro Construction is inevitably Deep soil-rock mixture backfill area is passed through, loosely organized, porosity is big, cementing energy since soil-rock mixture backfill has The characteristic features such as power is weak, stability is poor, permeability is strong, often occur cavern when underground engineering passes through buried backfill stratum It the problems such as large deformation, differential settlement, collapsing, infiltration, influences underground engineering normal construction, and buries for subsequent operation biggish Security risk.In order to preferably control soil-rock mixture backfill area stratum deformation, subway engineering is carried out on backfill stratum and is built If when, need to country rock carry out grouting and reinforcing, make hole week soil layer formed an annular Load -carring arch, guarantee hole week and face it is steady It is qualitative, and improve tunnel surrounding anti-permeability performance.Since block stone grain diameter is not of uniform size in the soil-rock mixture backfill of Mountainous City, and It is in the earth formation random distribution, rock-soil ratio in unit volume backfill is caused to differ greatly.Live note is carried out on backfill stratum When slurry is reinforced, lack the research to soil-rock mixture grouting serous fluid performance, the Diffusion Law of slurries etc., governed empirical data has Limit.In addition, slurry injection technique regulation (YBJ 44-1992) and urban track traffic Tunnel Engineering slurry injection technique regulation (DB11- The soil body involved by 1444-2017) is all homogenous material by note medium: rubble, gravel, coarse sand, middle sand, fine sand, flour sand, loess Deng, and the selection of soil-rock mixture slurry injection technique parameter can be according to it is poor that live wall rock grouting concretion forms effect without specification.Cause This, tunnel safety is built in the research of the grouting and reinforcing mechanism of earthen fill zone soil-rock mixture next time of different rock-soil ratios to be runed with stable With important engineering significance.
Since soil-rock mixture backfill is formed unevenly by note dielectric structure, grouting mechanism is complex, and related Research work is very few, and the selection of slurry injection technique parameter repeatedly tries slip casting effect dependent on Other Engineering experience or scene.In order to The grouting and reinforcing mechanism for disclosing soil-rock mixture backfill under the conditions of different rock-soil ratios needs to carry out different rock-soil ratio conditions bets Starch the research of diffusion mechanism and its influence factor.And original experimental rig has following shortcoming:
(1) after slip casting, discovery flows away there are liquid after slurries isolation and solid is deposited on barrel bottom around slurry-supplying valve Mouth is distributed in alluviation fan type.In such grouting test, size performance does not have representativeness.The test data obtained cannot answer For scientific research or practice.
(2) grouting test needs to prepare a large amount of soil samples, however can utilize a part around upper only slip casting nozzle, Soil sample waste is serious, and sample after the test is inconvenient to take out.
(3) the most complex and expensive of indoor grouting test equipment.
(4) none unified Seed harvest radius measuring method of indoor grouting test.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of indoor repeatable grouting test systems and Seed harvest radius to survey Determine method, it is ensured that slurries are all injected by note soil medium.Cylindrical slip casting bucket takes full advantage of soil medium.It removes Other than storage sizing device, other devices do not need customized and cheap, save fund, while keeping test easier easily Row.And propose a Seed harvest radius measuring method.
