An apparatus for measuring the sediment in slurry is composed of microcomputer, lifting unit with synchro, detecting assembly and weight rod connected via rope to synchro. Said detecting assembly connected via cable to microcomputer has a penetrating carrier,which is upward connected via central connecting tube to weight rod and has sediment top precaution detector and sediment bottom letector under it. The thickness of sediment can be correctly measured for ensuring the high quality and safety of deep foundation.
Description
The present invention relates to a kind of device that is used for the mensuration slurry and macadam of civil engineering, underground construction, geotechnical engineering and deep foundation engineering.
Development along with highrise building, heavy type structure and underground construction (subway, tunnel etc.); a large amount of deep foundation engineering all needs to utilize hole wall, the cell wall of mud protection excavation in digging process; so that concreting stake, post or subterranean wall; but; owing to there is slurry and macadam; influenced deep foundation engineering quality such as bored pile and diaphragm wall, if surpass 5 centimetres, will seriously reduce the stability of the bearing capacity and the diaphragm wall of foundation pile as slurry and macadam thickness.Therefore, the thickness that how to know slurry and macadam is the difficult problem of building operations, and it is sash weight that present unit in charge of construction adopts rope more, sinks to below the mud, judges with subjective experience by feel.Can imagine that judge gained mud thickness, its result must vary with each individual, and lacks quantitative parameter, the reliability extreme difference.In recent years, also someone's " electric logging " technology of trying to utilize geological exploration to use once, ask heavy quarrel by " microelectrode system " survey, but all to no effect, because they can't differentiate the boundary of mud and heavy quarrel effectively with this physical parameter of formation resistivity, and the boundary of heavy quarrel and following natural stratum.
The device that the purpose of this invention is to provide a kind of energy reliable determination slurry and macadam thickness.
Technical solution of the present invention is: measure the top and bottom of slurry and macadam by two kinds of different sensor-based systems, thereby determine the thickness of slurry and macadam:
(1) determines the top of mud by the mechanics parameter of material: in construction quality is identified, heavy quarrel (be mud at the bottom of) finally determine drilled pile or diaphragm wall build finish after, and, judge by boring core (coring) sampling whether heavy quarrel (at the bottom of the mud) is arranged then through curing concrete.Therefore, the definition of heavy quarrel should be can't be as the criterion from the extremely thick mud that (bottom land) at the bottom of the hole squeezes on the ground when the concreting.
(2),, determine the bottom of slurry and macadam by the static sounding of precision according to the characteristics that have the penetration resistance notable difference between slurry and macadam and natural stratum.
As mentioned above, the present invention includes microcomputer and the lifting gear that has from the positive angle machine, its characteristics be also to be provided with detection assembly and with the heavy bar of this detection assembly Joint, this heavy bar through lifting rope with connect mutually from the positive angle machine, this detection assembly then connects with circuit with microcomputer mutually through cable, wherein: this detection assembly comprises penetration carrier, and it mainly has the center tube connector to be connected with heavy bar up, and below be provided with quarrel top early warning and end face probe and quarrel end probe.
From structure of the present invention as can be known, when starting this device, from positive angle machine output degree of depth signal, when quarrel top early warning and end face probe contact mud one heavy quarrel intermediate zone (pressure is 5～10 kPas), send early warning signal, detection assembly continues injection slurry and macadam layer, when quarrel top early warning and end face probe reach (this is empirical value) when being forced to pressure and being 20～40 kPas, send and arrive slurry and macadam end face signal and demonstration, detection assembly passes through under continuing, (K is a spring constant), locking automatically when the displacement of quarrel top early warning and end face probe center sensor bar is equivalent to camber of spring S=0.5 MPa/K.But quarrel end probe passes through detection under still continuing, and touches natural stratum up to the tip, promptly heavy quarrel bottom end face, and (penetration resistance Ps 〉=1 MPa at this moment) stops injection, and sends arrival bottom surface signal, and shows slurry and macadam thickness.
Further, the penetration carrier among the present invention, it comprises the injection framework, is positioned at the center housing of these framework central authorities, connects the internal overarm support of framework and center housing and connects framework and the outer strut that weighs bar.This injection framework is circular frame, and its internal overarm support is three, and adjacent angle is 120 °; Its outer strut also is three, and inside and outside strut is hollow, and cable is from wherein passing through.The contact of strut on this injection framework coincides.This quarrel top early warning and end face probe comprise that detection dish, an end are fixed on this detection dish and the other end runs through center housing and be placed through center sensor bar in the tube connector, be positioned at the center housing place at this center sensor bar that synchronous compression spring and inductance displacement in mechanical-electric coupling are installed, and at the hydraulic pressure self-sealing cover that is nested with this center sensor bar of the lower port setting of center housing.In this center housing, also be provided with the butter kettle that matches with the hydraulic pressure self-sealing cover.The resolving power of this detection dish is 20～40 kPas; This heavy bar is the hollow-core construction of internal diameter =30 millimeter, and its weight adjustable range is 150～300 kiloponds.This quarrel top early warning and end face probe connect mutually with the center housing of penetration carrier; Probe is provided with three at the bottom of this quarrel, and its contact at injection frame upper contact and its internal overarm support coincides, probe is the single bridge probe of resistance-strain sensing at the bottom of this quarrel.Above-mentioned detection dish is in same horizontal plane with the tip of quarrel end probe.
Advantage of the present invention is: 1, the building of underlying concrete stake, post or subterranean wall for civil works, underground construction, geotechnical engineering and deep foundation engineering provides reliable scientific basis, judge the thickness of slurry and macadam objectively rather than by rule of thumb and subjectively, enable fundamentally to stop the Important Project accident and the economic loss that cause because of slurry and macadam; 2, structure of the present invention is very simple and clear, easy to implement and maintenance.
