Description
Technical Field
The application relates to the technical field of geotechnical engineering equipment, in particular to an adjustable pile foundation drilling mud liquid proportion monitoring device.
Background
The drilling mud is a mixed slurry consisting of water, bentonite (or clay), additives and the like. In the construction process of the drilled pile, when slurry circulates, the pressure difference between the slurry and underground water is utilized to control the water pressure, so that the slurry can form a mud skin on the hole wall to reinforce the hole wall and prevent collapse, and meanwhile, the water level in the hole is stabilized. Meanwhile, the mud also has the functions of carrying out rock-soil fragments, cooling and lubricating the drill bit. Therefore, the pile forming quality is greatly influenced no matter in the hole forming stage or the pouring stage, and the bearing performance of the pile foundation is greatly influenced.
The bored pile with the slurry effect of the bored pile is suitable for various soil qualities, has no vibration, low noise and simple and reliable process, and is widely applied to engineering. However, there is no unified understanding of drilling mud in terms of its performance and effectiveness. Therefore, in the drilling process, due to the fact that the performance indexes of the slurry are not tightly controlled, the phenomena of hole wall collapse, incomplete hole cleaning, guide pipe blockage, slow drilling, serious abrasion of a drilling tool and the like occur.
In the process of forming the hole, the specific gravity of the used slurry is more (more than 1.25) in order to stabilize the hole wall, the balance between the drilling hole and the stratum can be maintained, the stability of the hole wall is maintained, and the capacity of suspending drilling slag is improved, but the specific gravity of the slurry is improved, which means that the content of useless solid phase in the slurry is higher, so that the mud skin attached to the hole wall is thicker, the mud skin is loose and has lower toughness, the hole wall can be reduced in diameter, the hydration collapse of the hole wall can be caused, the mud skin can fall off, the hole cannot be purified, and the hole cleaning is difficult. In addition, the slurry has high content of useless solid phase, which tends to greatly abrade pipes, drill bits, water pump lever sleeves, impellers and the like, and the service life of the slurry is shortened. Moreover, the useless solid phase content is high, the footage of the drill bit is dragged, so that the clay and rock debris particles are repeatedly crushed, the dispersion degree of the mud debris is high, and the mechanical drilling speed is reduced.
The drilling mud consists of water, clay (or bentonite) and additives. Because the specific gravity of the slurry is greater than that of water, the stability of a hole wall is mainly maintained in the hole forming process, the balance of force between a drilling hole and a ground layer is maintained, drilling slag is carried and suspended, and the lubricating and cooling drill bit also has the functions. The specific gravity of the slurry is determined by the solid content of the slurry, which is the percentage by weight or volume of the solid particles in the slurry, and the specific gravity of the solid phase. The magnitude of the mud weight directly affects the stability of the bore wall, the mechanical drilling and the underwater concrete pouring. When the specific gravity is large, the balance of the forces between the drilled hole and the ground layer can be maintained, but the adverse effect on the construction is not so much. For example: the pile body can be clamped with mud. Particularly, in a stratum with more clay, due to the fact that drilling is too fast, one-time hole cleaning is not thorough, so that mud blocks with more sizes in holes are caused, when the specific gravity of mud is too large, the mud blocks can be hung on a reinforcement cage or suspended in the mud, after concrete pouring is started, a part of the mud blocks are clamped in a pile body (the defect of integrity of the pile body can be found when small strain detection is carried out seriously), and a part of the mud blocks clamp the reinforcement cage, so that the reinforcement cage floats upwards; the most serious condition is that the whole reinforcement cage top is deformed, the guide pipe is hooped, the pouring of the pile fails, only holes or waste piles can be drilled again, the pile driving is good and the like, the excavation of a bearing platform foundation is clear, mud is clamped around the poor pile body, concrete is separated, the edges of the reinforcement contain dry mud for wrapping, and the like.
Effect of mud weight on catheter perfusion: when concrete is poured, the concrete and slurry outside the pipe are lifted mainly by the pressure of the concrete column in the pipe, and the mud on the wall of the hole is extruded by impact. The fluidity of concrete changes with the change of environmental medium and also with the change of specific gravity of the medium. The specific gravity of the slurry in the pile hole is high, and the diffusion retardation effect is increased after the concrete flows out of the guide pipe, so that the concrete flowing out of the bottom opening of the guide pipe cannot lift the concrete on the top in the pile hole, and the pipe blockage accident is caused.
The traditional equipment and instrument for testing the mud proportion is a mud proportion tester, manual sampling is adopted by the instrument, testing is carried out in a laboratory, the detection efficiency is low, time and labor are wasted, the early warning of the mud proportion value in real time is difficult to realize, and the control of the mud proportion of a construction site is not facilitated.
Therefore, there is a need to provide an improved solution to the above-mentioned deficiencies of the prior art.
