Description
Technical field
The present invention relates to a kind of method measured for plastic conduit degree of being backfilling and compacted.
Background technology
The quality of buried drain pipe road backfill quality, directly affects the life-span of pipeline.In prior art, right
Use in job site Special compacted degree measurement apparatus to detect, but operating procedure is complicated, it is impossible to carry out
Fast, easy operation.
Summary of the invention
The technical problem to be solved in the present invention is: existing plastic conduit degree of being backfilling and compacted in work progress is surveyed
The problem that amount is inconvenient, it is provided that a kind of easy and simple to handle, with low cost for plastic conduit degree of being backfilling and compacted
The method measured.
The present invention is to solve above-mentioned technical problem by following technical proposals:
A kind of method measured for plastic conduit degree of being backfilling and compacted, its feature is, it includes walking as follows
Rapid:
S1: measure the inner diameter of plastic conduit；
S2: choose the length straight-bar more than the inner diameter of described plastic conduit；
S3: the two ends of described straight-bar are resisted against the inwall of described plastic conduit；
S4: the outer wall at described plastic conduit backfills；
S5: observe the deformation of described plastic conduit until described straight-bar comes off from the inwall of described plastic conduit.
By using the length straight-bar more than the inner diameter of plastic conduit so that straight-bar is resisted against plastic conduit
After inwall, can make plastic conduit that a certain degree of deformation occurs, the inwall of plastic conduit is produced by straight-bar
Active force；And when the outer wall of plastic conduit is by a bigger power (more than the straight-bar active force to inwall)
During effect, straight-bar can be made to come off from plastic conduit inwall.
It is preferred that the inner diameter of described plastic conduit is more than 1000mm.
It is preferred that the material of described straight-bar is wooden.
It is preferred that the 101%-103% of the inner diameter of a length of described plastic conduit of described straight-bar.Should
The active force that the straight-bar of length range produces for plastic conduit inwall tamps rear plastic conduit with banketing
Whether the active force close range suffered by outer wall, can be used to judgement and banket and tamp, and then judges to fill out back
Compactness whether conformance with standard.
It is preferred that the 102% of the inner diameter of a length of described plastic conduit of described straight-bar.
It is preferred that among step S3:
Described straight-bar is vertically arranged at the inwall of described plastic conduit.
It is preferred that in step s 4:
Outer wall at the described plastic conduit being parallel to each other with described straight-bar backfills.Due to plastic conduit
It is to be embedded in below road surface, the pressure being primarily subjected on vertical direction, and vertical pressure will cause plastic tube
Road deformation in the horizontal direction, therefore, in order to prevent plastic conduit deformation in the horizontal direction, needs
Plastic conduit both sides in the horizontal direction are tamped.
The most progressive effect of the present invention is: avoids use Special compacted degree measurement apparatus and detects
The inconvenience brought, it is simple to detect compactness at the scene in operating process.
Accompanying drawing explanation
Fig. 1 is the flow chart of the method measured for plastic conduit degree of being backfilling and compacted of one embodiment of the invention.
Fig. 2 is the structural representation that the straight-bar of one embodiment of the invention is resisted against the inwall of plastic conduit.
Description of reference numerals:
Plastic conduit 1
Wooden straight-bar 2
Inwall 11
Outer wall 12
Detailed description of the invention
Further illustrate the present invention below by the mode of embodiment, but the most therefore limit the present invention to
Among described scope of embodiments.
Embodiment
Understood incorporated by reference to Fig. 1-2, a kind of method measured for plastic conduit degree of being backfilling and compacted, its
Comprise the steps:
S1: measure the inner diameter of plastic conduit 1.The preferably inner diameter plastic tube more than 1000mm
Road；
S2: choose the length wooden straight-bar 2 more than the inner diameter of plastic conduit 1, wooden straight-bar 2 is long
Degree is the 101%-103% of the inner diameter of plastic conduit 1, preferably 102%；
S3: wooden straight-bar 2 is vertically arranged at the inwall 11 of plastic conduit 1, wooden straight-bar 2
Two ends be resisted against the inwall 11 of plastic conduit 1；
S4: the outer wall 12 of the plastic conduit 1 being parallel to each other with wooden straight-bar 2 backfills；
S5: observe the deformation of plastic conduit 1 until wooden straight-bar 2 takes off from the inwall 11 of plastic conduit 1
Fall.
Being understood incorporated by reference to Fig. 1-2, the principle of the present invention is:
First, by length being slightly longer than the wooden straight-bar 2 of the inner diameter of plastic conduit 1 along vertically side
To being supported on the inwall 11 of plastic conduit 1, plastic conduit 1 shape is made to become slightly longer on vertical direction, whole
The shape of ovalize on body, and the inwall 11 of plastic conduit 1 can produce for wooden straight-bar 2 simultaneously
Clamping；
Secondly, the both sides that outer wall 12 and the wooden straight-bar 2 at plastic conduit 1 is parallel to each other backfill,
When banket enough consolidations when, banket and the both sides outer wall 12 of plastic conduit 1 can be formed pressure, make
The outer wall 12 of plastic conduit 1 by the pressure in horizontal direction, in turn result in plastic conduit 1 perpendicular
Nogata upwards deformation further.
Finally, when the deformation of plastic conduit 1 reaches to a certain degree when, wooden straight-bar 2 is from plastic tube
Road 1 comes off, can tentatively judge with this, banket and tamped.
Although the foregoing describing the detailed description of the invention of the present invention, but those skilled in the art should managing
Solving, these are merely illustrative of, and protection scope of the present invention is defined by the appended claims.This
The technical staff in field, can be to these embodiment party on the premise of without departing substantially from the principle of the present invention and essence
Formula makes various changes or modifications, but these changes and amendment each fall within protection scope of the present invention.
