Description
Technical field
The invention belongs to road engineering technical field, relate to a kind of widening road bed fixed level inclination probe and advance
Device.
Background technology
In Widening of Freeway engineering, widening road bed settlement measurement is for ensureing subgrade stability, rationally determining road
Face structure sheaf constructions etc. are significant.Owing to widening road bed width is little, settlement plate is used to measure construction shadow
Ring big, and settlement plate protection difficulty, the seriality of certainty of measurement and data cannot ensure, therefore, is generally adding
Broad way basilar part buries cross-sectional pipe (as shown in Figure 2) underground, and drags fixed level inclination probe in cross-sectional pipe
Carry out the settlement measurement of subgrade cross section.When cross-sectional pipe is buried underground, one end is positioned at outside widening road bed side slope face, and one
End is sealed in new and old roadbed intersection.During sedimentation test, first probe is put into leading of cross-sectional tube opening end inwall
In groove, then inwardly slowly promote probe, until the other end sealed.At a certain distance (generally 50cm)
Note single reading, according to the difference of twice reading of front and back and through conversion, can calculate the ground in this time period and sink
Fall amount.
Owing to, in Widening of Freeway engineering, cross-sectional pipe is embedded under widening road bed, one end open, an end seal
Close, and the whole roadbed section of non-through, it is impossible to permissible as newly-built roadbed runs through the cross-sectional pipe of roadbed section
Two ends drag level inclination probe, and this is accomplished by one and level inclination probe is pushed to cross-sectional duct occlusion one end
Device.This device should meet following condition: the connection that (1) pushing ram and level inclination are popped one's head in should firmly and also have
There is natural activity.Because subgrade settlement makes cross-sectional pipe be not at level, connect insecure meeting and make propelling
Bar departs from probe, causes advancing probe；Connect and the tightliest can affect pushing ram and probe in cross-sectional pipe
Advance, cause obstacle for measuring；(2) connection between pushing ram will firmly, easily operate.In reality is measured,
Typically require several pushing rams of installation and probe is advanced to designated depth, so firmly simple connected mode,
It is to ensure that certainty of measurement, promotes the key measuring efficiency.(3) material of pushing ram should have certain hardness and
Pliability.Cross-sectional pipe can bend with subgrade settlement, and propulsion plant may cause probe and pushing ram the most firmly
It is stuck in cross-sectional pipe；Too soft, pushing ram can be made cannot to make smooth advances probe.At present, there is not yet meet above-mentioned want
The fixed level inclination probe propulsion plant asked.
Therefore, design a kind of sound construction, easily operated fixed level inclination probe propulsion plant, for
Improve widening road bed settlement measurement efficiency and precision etc., there is important practical engineering value.Apparatus of the present invention are complete
Full up sufficient above three condition: (1) connects pushing ram with cuff and pops one's head in level inclination, and the lipostomous of cuff can
To ensure that cuff is firmly connected with probe, and fixing hole can ensure that the motility that pushing ram is connected with cuff；(2)
Concave joint and convex joint are installed in pushing ram both sides, if simply rotate during use can lengthen or
Shorten, not only firmly but also facilitate.(3) pushing ram is PPR plastic tube, has hardness and toughness concurrently, it is easy to buy and
Processing.
