Abstract
The invention discloses a method for detecting the slip casting effect on ground surface, which comprises the following steps of: before slip casting and after slip casting on engineering structures such as the ground surface or a side slope, an ultrasonic CT scanning system is used for probing the situation of an adjacent rock for twice, and then the result data of the ultrasonic CT scanning detections before the slip casting and after slip casting is compared and analyzed; a distribution map of the slip casting grout is drawn, thus accurately judging the effect of the slip casting on the ground surface. The invention relates to a method for detecting the slip casting effect on ground surface, which uses the ultrasonic CT scanning system for probing the situation of the adjacent rock for twice, can clearly prove up the distribution and trending of the grout in the mass body of the ground surface and the compaction rate of the rock mass after slip casting.
Description
Technical field
The present invention relates to the method that a kind of face of land slip casting effect detects, particularly relate to a kind of method of using ultrasound wave CT scan system to detect face of land slip casting effect.
Background technology
Slip casting has obtained using widely in many fields such as building, water conservancy, mine, traffic as a kind of special construction method.When building railway or highway, slip casting method commonly used is come reinforcing road bed loose soft soil, and phreatic flowing with displacement, sedimentation and the landslide etc. of control foundation soil body limited in the space in the matrix rock soil body.
For the effect detection after the slip casting, the present flexible ripple method of using of method, dynamic and static feeler inspection method, methods such as core method, radioactive ray density measurement are got in sampling.These methods all belong to a little detects, rather than the zone detects, and that is to say that probe result can only confirm to detect the hole and a bit have or not slurries, and can not prove whether a scope of detecting around the hole exists slurries.Because the number of inspecting hole can not be a lot, the result who detects has very big contingency, can't learn especially as for actual distribution state and the degree of agreement of the predetermined injection scope of design, the compaction rate after the rock soil mass slip casting of slurries in the stratum.Along with the continuous appearance of various reinforcement means, slip casting construction method wants to keep intrinsic advantage, establishes oneself in an unassailable position, and only overcomes above-mentioned weakness, the needs of the development that can adapt to the situation.
Summary of the invention
Technical matters to be solved by this invention provides a kind ofly can clearly verify distribution and the trend of slurries in the rock soil mass of the face of land, and the method that detects of the face of land slip casting effect of the compaction rate after the rock mass slip casting.
In order to solve the problems of the technologies described above, the method that the face of land provided by the invention slip casting effect detects, before to engineering structure such as the face of land or side slope slip casting and after the slip casting, use for twice ultrasound wave CT scan system to survey the situation of country rock, and then the ultrasound wave CT scan testing result data before and after the slip casting are compared, analyze, draw the grouting serous fluid distribution plan, thereby correctly judge the effect that face of land slip casting obtains.
The method that described face of land slip casting effect detects may further comprise the steps:
(1), drill through first exploration hole and second exploration hole respectively, keep inspecting hole unimpeded at the regional two ends of prepare implementing slip casting;
(2), in first exploration hole, lay the ultrasonic launching head of ultrasonic emitting and receiving trap, in second exploration hole, lay the ultrasound wave of ultrasonic emitting and receiving trap and accept probe, ultrasonic launching head and ultrasound wave are accepted probe and are promoted and decline through first pulley, second pulley and signal cable winch respectively, ultrasonic emitting is connected department of computer science unify opertaing device and adjusting instrument parameter with receiving trap;
(3), start ultrasonic emitting and receiving trap and signal cable winch, since first exploration hole and second exploration hole bottom, when measuring, parameter such as wave amplitude;
(4), the data of obtaining are carried out analysis and judgement, the position, crack of mark rock mass on sectional drawing;
(5), roadbed or side slope are carried out mortar depositing construction;
(6), repeating step 2 and 3;
(7), the employing specific program is handled the crack distribution plan of rock mass after the drafting slip casting to the data of obtaining;
(8), the rock cranny distribution plan that obtains before and after the slip casting is analysed and compared the distribution situation and the slip casting effect of judgement grouting serous fluid.
Adopt the method for the face of land slip casting effect detection of above-mentioned technical matters, its principle of work is that test is when passing the ultrasound wave that detects on the section and walking, adopt suitable algorithm inverting to detect the distribution situation of ultrasonic velocity on the section again, determine to detect the distribution of different materials on the section at last according to the relation of ultrasonic velocity and material, thereby show the inner structure of detected object.
In sum, the present invention is the situation that a kind of twice use ultrasound wave CT scan system surveys country rock, can clearly verify distribution and the trend of slurries in the rock soil mass of the face of land, and the method for the face of land slip casting effect detection of the compaction rate after the rock mass slip casting.
