Description
Technical field
The present invention relates to a kind of injection bar lifting appliance, particularly relate to a kind of light-duty feeler inspection injection bar lifting appliance for roadbed side slope and method for improving.
Background technology
Light dynamic penetration test (the heavy 10kg of hammer) utilizes certain hammering energy, the circular cone of certain specification probe is squeezed in soil, according to injection blow counts differentiate soil layer classification, determine soil engineering properties, foundation soil is made to the on-site land survey method of overall merit.
In actual application, during owing to promoting the injection bar of light dynamic penetration test, the impact of hole wall collateral resistance can be subject to; And when the injection of injection bar, due to probe not strictly vertical injection, make the lifting of injection bar very difficult; In addition, under the extreme terrains such as side slope, the lifting of injection bar is then more difficult.Usually, the injection bar method for improving of light dynamic penetration test has several as follows.
First method: carry out artificial dead man and lifting by the mode added water in feeler inspection hole.After adding water in feeler inspection hole, wet the soil body around hole wall, the cohesion of this soil body is reduced, simultaneously due to the lubrication of water, made the corresponding reduction of the collateral resistance around hole wall, thus made to become easier when promoting injection bar.But when carrying out portable dynamic penetration test to building lot and highway foundation, due to depth of penetration large (generally reaching more than 2m), although efficiency is higher when adopting the method, but because added water exists in ground always, certain impact is produced by foundation strength, especially, when old road side slope carries out light dynamic penetration test in reconstruction and extension project, the existence of water rheobasic impact of satisfying the need is more obvious.In addition, if injection bar or probe surrounding meet small crushed stone or block stone, even if add water in hole, artificial lift's injection bar is still very difficult.
Second method: punching hammer recoil method.The method is after feeler inspection hammering completes, and adopts artificial mode, lifts punching hammer, upwards impacts the pad of guide rod upper end, and then promote injection bar.Although the method can reach the object promoting injection bar, there is following shortcoming: (1) needs manually to provide very large upwards impact force, after depth of penetration reaches the 2m degree of depth, due to the impact of collateral resistance, will require great effort very much, and efficiency is very low; (2) to guide rod and testing equipment serious wear, the continuation test of light dynamic penetration test equipment is unfavorable for; (3) adopt the method when carrying out lifting injection bar on roadbed side slope, operating personnel exert all one's strength difficulty, and there is serious potential safety hazard.
The third method: adopt the mode of excavation to be extracted by injection bar.Though injection bar can take out by the method smoothly, there is distinct disadvantage, namely excavated volume is large, does not meet the original intention of portable dynamic penetration test in-situ test, destroys the original state of soil structures.
4th kind of method: adopt hydraulic tube drawing bench.Though the method utilizes machinery can promote injection bar smoothly, operating process is complicated, and equipment is heavy; When especially promoting injection bar on highway subgrade slope, lifting means is mobile very difficult on slope.
Lung biopsy: adopt hoist engine to promote.The method adopts electric power to promote, do not need artificial, but when highway foundation and roadbed side slope place adopt hoist engine to promote, following problem can be run into: (1) power supply is connected inconvenient or needed external power supply to power, the time of such lifting means will be long, and also bring new Electrical Safety problem; (2) when adopting hoist engine to promote injection bar on roadbed side slope, need in advance smooth go out a working platform, waste time and energy, and hoist engine is also heavier, mobile difficulty on roadbed side slope.
Therefore, those skilled in the art is devoted to injection bar lifting appliance and the method for improving of developing a kind of light-duty feeler inspection, to be applied to the compactibility and bearing capacity that detect building lot and highway foundation fast.
