On August 5th, 2011, the contriver carried out the test of aspects such as intensity to septic tank to August 31, made evaluation with this mechanical property to septic tank.Situation is following:
Specimen: sample 1,2 is the plastics of the screening formulation of prescription 1 and processes through process method of the present invention, and sample 1 is that cylindric septic tank, sample 2 are olive-shaped septic tank shown in Figure 1.
Testing tool:
(1) two-way resistance strain gage
(2) YE2539 high speed statical strain indicator
(3) YE2539 control software
38 monitoring points of uniform distribution on the housing on the sample 1,24 check points of uniform distribution on the sample 2.Whether the intensity of mainly examining two samples in the test can satisfy request for utilization, and the strain value of septic tank under the different injection degree of depth, the different backfill degree of depth mainly gathered in test, and concrete steps are following:
1, septic tank I (original state is for being backfilled to half barrel of degree of depth):
1) is filled to half;
2) fill with;
3) be backfilled to the bucket top;
4) earthing 0.5m;
5) earthing 1m;
6) earthing 1.5m;
7) earthing 2m;
8) monitoring is 24,48,72 hours; Wherein beginning in 48 hours is the data of ramming through water.
2, septic tank II (original state is for being backfilled to half barrel of degree of depth):
1) is backfilled to the bucket top;
2) be filled to half;
3) fill with;
4) earthing 0.5m;
5) earthing 1m;
6) earthing 1.5m;
7) earthing 2m;
8) monitoring is 24,48,72 hours, and wherein beginning in 72 hours is the data of ramming through water.
In the above-mentioned test, for investigating the tolerance performance of septic tank, earth-filling method is compared harsher with the installation method of the use occasion that requires, more possibly cause damage to sample.
1, sample 1 stress value
Stress value (MPa) under table 1 sample 1 each operating mode
2, sample 2 stress values
Stress value (MPa) under table 2 sample 2 each operating mode
Test result:
Can find out by above-mentioned data that (one) along with the rising of fill level, the increase of the backfill degree of depth, the stress value of each measuring point of septic tank is linear basically to be increased progressively.Except that the part point, most of measuring point stress values are less.Stress distribution on the interpret sample is comparatively even.
(2) dangerous point 16,21 stress values are obviously bigger in the sample 1, and monitoring is after 72 hours, and maximum stress value 10.479MPa appears in point 16.
After sample 1 drew water, each measuring point stress value obviously rose, and its mid point 16 reaches 11.05MPa, so septic tank is in normal use, and its water level inside will directly have influence on the stressing conditions of septic tank.
(3) dangerous point is 2,7,16 in the sample 2.After the monitoring to 72 hour, maximum stress value 24.328MPa appears in point 7.
(4) sample 1,2 carries out the permeability test detection with water filling on inspection after finishing after the off-test, and two samples all do not have any destruction.
