Description
Technical field
The utility model belongs to construction project technical field, is related to flowing pressurization when injection entirely in a kind of conventional articulated gravity field
Device.
Background technique
Full flowing penetrometer is the novel strength test element of one kind of rising in recent years, at home and abroad the original of clayey soil
It is widely used in bit test and the test of geo- textile technique soil sample.It, which has, does not need amendment burden pressure, can be with
Soil body continuous shear stress intensity is obtained, and there are stringent Plastic Solution and warps since flow mechanism complete in penetration process makes it
Cross the advantages that circulation penetration test can be quickly obtained soft clay remodeling resistance.Therefore, Quan Liudong penetrometer is in coastal waters soft clay
It is widely used during the place strength test of deposition.But only when soil strength to be measured is lower, test
Shi Tuti complete around popping one's head in can flow, and then obtain accurate penetration resistance, and the shearing resistance of the calculating acquisition soil body is strong
Degree, above advantages can just access embodiments, and when soil strength is higher, the soil body can not be around probe entirely in penetration process
Flowing, therefore certain influence can be generated to the accuracy of test result.
Utility model content
The utility model provides a kind of pressurizing device when flowing injection entirely in conventional articulated gravity field, overcomes due to the soil body
Intensity is excessively high to flow in penetration process the soil body entirely from flowing complete around probe, and then influence test result is accurate
Property.By applying gas pressure to soil body surface in penetration process, the promotion lower part soil body flows the device entirely in detecting head surface,
To reach increase strength test range and make the more accurate purpose of test result.
The technical solution of the utility model includes:
Flow pressurizing device when injection in a kind of conventional articulated gravity field entirely, which includes consolidation case 1, top cover 3, close
Seal rubber ring 5, air pump 8, aerating hole 6 and pressure gauge 4.The soil body is placed in 1 top opening of consolidation case, inside；The top cover 3
It is closely coupled by connecting screw 9 and consolidation case 1, it is ensured that sealing；Pressure gauge 4, Quan Liudong penetrometer 2 are set on top cover 3 and added
Stomata 6；The pressure gauge 4 is for detecting whether gas pressure size in consolidation case 1 reaches desired value；The full flowing is passed through
Enter instrument 2 across top cover 3, and packer ring 5 is set between top cover 3, it is ensured that the sealing to consolidation case 1；The aerating hole 6
It is connected by snorkel 7 with air pump 8, for applying pressure for the soil body surface in consolidation case 1, thus the soil body for promoting intensity high
Full flowing occurs in the detecting head surface of flowing penetrometer 2 entirely, and passes through the air pressure size inside the monitoring consolidation case 1 of pressure gauge 4.
The full flowing penetrometer 2 is T-bar.
The soil body is in consolidation case 1 through having been consolidated under precalculated consolidation stress effect within a certain period of time
At.The utility model has the advantages that promoting the high-intensitive soil body in turn can be with the higher clay of test intensity in the full flowing of detecting head surface
Intensity, increase the test scope of soil strength, while also can be improved the accuracy of test result.
The utility model has the beneficial effects that the soil strength range that traditional full flowing penetrometer can be tested is smaller, only
Low intensive soft clay can be tested.The utility model promotes the soil body to be measured around probe by applying air pressure to soil body surface
Full flowing, to achieve the purpose that test the higher intensity soil body.It only needs to set the size for needing to apply air pressure before the test
Injection can be carried out, test process is simple and convenient.And for the ocean soil of gravity tank sampling, its stress state changes, and leads to
Crossing top application pressure can be such that its stress state returns to original state, and can carry out soil strength to it at once after sampling
Test.
Detailed description of the invention
Fig. 1 is the front view of utility model device.
Fig. 2 is the top view of utility model device.
In figure: 1 consolidation case；2 full flowing penetrometers；3 top covers；4 pressure gauges；5 packer rings；6 aerating holes；7 snorkels；

Specific embodiment
Specific embodiment of the present utility model is described below in conjunction with attached drawing.
Pressurizing device when injection, including consolidation case 1 are flowed in a kind of conventional articulated gravity field entirely, consolidating on case 1 has one and its
By the close-connected top cover 3 of connecting screw 9, be fixed on top cover 3 pressure gauge 4 for detect consolidate case 1 in gas pressure
Whether size reaches desired value；An aerating hole 6 is got on top cover 3 simultaneously to be connect with air pump 8 by snorkel 7, be used for
It is passed through gas in consolidation case 1, pressure is applied to soil body surface；And a certain size notch sealing is excavated at the center of top cover 3
Rubber ring 5, which is sealed, makes to consolidate 1 inside of case and extraneous gas isolation；Top cover 3 and packer ring 5 make as sealing device
Gas in consolidation case 1 can reach expected pressure value, so that the soil body be promoted to flow entirely around penetrometer probe.T-
Full flowing penetrometer of the bar 2 as test soil strength.
The application method of pressurizing device, steps are as follows:
Preparation stage before injection will consolidate the precosolidation stress of the soil body to be measured in case 1 as requested and carry out
Consolidation, after the completion of consolidating, according to the size for the gas pressure that the estimation of the consolidation situation of the soil body needs to apply.Because the soil body occurs
Consolidation settlement, so the presence in the space, which has, is conducive to full flowing there are certain space between on top cover 2 and consolidation case 1
The 2 injection soil body of penetrometer, while applying pressure to soil body surface for gas and providing steric requirements.
Pressurizing device is used as main peripheral structure by consolidation case 1 when flowing injection entirely in a kind of conventional articulated gravity field, to be measured
Clay is consolidated in consolidation case 1 and is completed.Top cover 3 is connected firmly by connecting screw 9 with case 1 is consolidated, with snorkel 7 by air pump
8 closely connect with the aerating hole 6 on top cover 3.T-bar is passed through into the packer ring 5 on top cover 3；Pressure gauge 4 is fixed on top
On lid 3, for monitoring the gas pressure size in consolidation case 1.It, can be according to the consolidation of the soil body after all device connections are firm
Apply gas pressure size needed for degree estimation, gas is passed through into consolidation case 1 by air pump 8, then by T-bar injection to soil
In body, accurate soil body penetration resistance can be obtained, while the soil strength range tested also will increase, and make to flow injection entirely
Instrument can more be widely used in the detection of soil strength.
