Description
Technical field
The present invention relates to a kind of methods for the measurement of plastic conduit degree of being backfilling and compacted.
Background technique
Buried drain pipe road backfills the quality of quality, directly affects the service life of pipeline.In the prior art, for construction site
It is detected using Special compacted degree measuring device, but operating procedure is complicated, can not carry out quick, easy operation.
Summary of the invention
The technical problem to be solved by the present invention is degree of being backfilling and compacted measurement is inconvenient in the construction process for existing plastic conduit
The problem of, a kind of easy to operate, low-cost method for the measurement of plastic conduit degree of being backfilling and compacted is provided.
The present invention is to solve above-mentioned technical problem by following technical proposals:
A method of it is measured for plastic conduit degree of being backfilling and compacted, it is characterized in that comprising following steps:
S1: the inner diameter of plastic conduit is measured；
S2: the straight-bar that length is greater than the inner diameter of the plastic conduit is chosen；
S3: the both ends of the straight-bar are resisted against to the inner wall of the plastic conduit；
S4: it is backfilled in the outer wall of the plastic conduit；
S5: the deformation of the plastic conduit is observed until the straight-bar falls off from the inner wall of the plastic conduit.By making
It is greater than the straight-bar of the inner diameter of plastic conduit with length, so that plastics can be made after straight-bar is resisted against the inner wall of plastic conduit
A degree of deformation occurs for pipeline, and straight-bar generates active force to the inner wall of plastic conduit；And when plastic conduit outer wall by
When one bigger power (greater than straight-bar to the active force of inner wall) effect, straight-bar can be made to fall off from plastic conduit inner wall.
Preferably, the inner diameter of the plastic conduit is greater than 1000mm.
Preferably, the material of the straight-bar is wooden.
Preferably, the length of the straight-bar is the 101%-103% of the inner diameter of the plastic conduit.The length range
The active force that generates for plastic conduit inner wall of straight-bar and banket and tamp active force model suffered by the outer wall of rear plastic conduit
It encloses close, can be used to judge to banket and whether tamp, and then judge to fill out whether back pressure solidity complies with standard.
Preferably, the length of the straight-bar is the 102% of the inner diameter of the plastic conduit.
Preferably, among step S3:
The straight-bar is set to the inner wall of the plastic conduit along the vertical direction.
Preferably, in step s 4:
It is backfilled in the outer wall for the plastic conduit being parallel to each other with the straight-bar.Since plastic conduit is to be embedded in road
Face hereinafter, be primarily subjected to the pressure on vertical direction, and vertical pressure will will lead to the deformation of plastic conduit in the horizontal direction,
Therefore, the deformation of plastic conduit in the horizontal direction in order to prevent needs to tamp the two sides of plastic conduit in the horizontal direction.
The positive effect of the present invention is that: it avoids brought by being detected using Special compacted degree measuring device
Inconvenience, convenient for detecting compactness in operating process at the scene.
Detailed description of the invention
Fig. 1 is the flow chart of the method for the measurement of plastic conduit degree of being backfilling and compacted of one embodiment of the invention.
Fig. 2 is the structural schematic diagram that the straight-bar of one embodiment of the invention is resisted against the inner wall of plastic conduit.

Specific embodiment
The present invention is further illustrated below by the mode of embodiment, but does not therefore limit the present invention to the reality
It applies among a range.
Embodiment
Understood incorporated by reference to Fig. 1-2, a method of it is measured for plastic conduit degree of being backfilling and compacted comprising following step
It is rapid:
S1: the inner diameter of measurement plastic conduit 1.It is preferred that inner diameter is greater than the plastic conduit of 1000mm；
S2: choosing the wooden straight-bar 2 that length is greater than the inner diameter of plastic conduit 1, and wooden 2 length of straight-bar is plastic conduit
The 101%-103% of 1 inner diameter, preferably 102%；
Wooden straight-bar 2: being set to the inner wall 11 of plastic conduit 1 by S3 along the vertical direction, and the both ends of wooden straight-bar 2 are resisted against
The inner wall 11 of plastic conduit 1；
S4: the outer wall 12 for the plastic conduit 1 being parallel to each other with wooden straight-bar 2 is backfilled；
S5: the deformation of observation plastic conduit 1 is until wooden straight-bar 2 falls off from the inner wall 11 of plastic conduit 1.
Understood incorporated by reference to Fig. 1-2, the principle of the present invention is:
Firstly, being supported on modeling along the vertical direction by the wooden straight-bar 2 for the inner diameter that length is slightly longer than to plastic conduit 1
The inner wall 11 of pipe material 1 makes 1 shape of plastic conduit become slightly longer, oval shape on the whole on vertical direction, and plastics
The inner wall 11 of pipeline 1 can generate the clamping for wooden straight-bar 2 simultaneously；
Secondly, backfilled in the outer wall 12 of plastic conduit 1, the two sides that are parallel to each other with wooden straight-bar 2, when banketing enough
When consolidation, meeting of banketing forms pressure to the two sides outer wall 12 of plastic conduit 1, so that the outer wall 12 of plastic conduit 1 is by water
It square upwards pressure, in turn results in the further deformation in the vertical direction of plastic conduit 1.
Finally, wooden straight-bar 2 falls off from plastic conduit 1 when the deformation of plastic conduit 1 reaches a certain level,
It can tentatively be judged with this, banket and tamped.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
Under the premise of from the principle and substance of the present invention, many changes and modifications may be made, but these are changed
Protection scope of the present invention is each fallen with modification.
