Technical field
This utility model relates to a kind of construction monitoring system, especially a kind of dynamic consolidation construction automatic monitoring device.
Background technology
Strong rammer completes work mainly by the impact endurance test shock effect of hammer ram.Machine rammer can be divided into firepower rammer, frog rammer and speed rammer impactor etc..This patent is mainly called for short strong rammer for invention basis with speed rammer impactor.
Heavy-tamping method, also known as dynamic consolidation method (DynamicConsolidation), is a kind of reinforcement means processing soft soil foundation.Dynamic compaction machinery (dynamiccompaction) is a kind of important ballast consolidating machine in engineering machinery field, fills out silt cutting into a mountain, reclaims land from the sea, mountain area backfill, has a wide range of applications in the basement process such as airport construction.It is late 1960s to be developed by France engineer Louis and created use.It utilizes crane gear that hammer ram (8～40t) is risen to the biggest height (10～40m), then hammer ram free-falling is made, act on ground with great impact energy (500～8000KN m), soil produces the biggest shock wave, to overcome the various resistances between soil particle, make ground densification, thus improve the intensity of ground, reduce sedimentation, Compaction variables, dilatancy, improves Anti-liquefying asility.Heavy-tamping method has been widely used in the Base Consolidation Engineering of the foundation engineering such as airfield runway and power station dam, reservoir the most.
At present, strong rammer engineering construction DATA REASONING and engineering site monitoring nearly all use manual measurement mode.Manual measurement method causes work progress and construction quality parameter credibility to reduce, and workmen the most easily uses inferior materials and turns out substandard goods, thus causes construction quality uncontrollable, causes economic loss.Particularly, will accurately measure the settling height every time rammed a great problem the most in the industry, the present invention solves this difficult problem and those problems aforesaid, can be that large-scale dynamic consolidation construction provides complete engineering construction data, provides data to ensure for improving construction quality.
Dynamic compaction machinery is as main equipment indispensable in foundation construction, and being widely used in cuts into a mountain fills out silt, reclaim land from the sea etc. in building foundation treatment and road, Aerodrome construction engineering, is used for pounding basis.The dynamic compaction machinery of prior art, is to use lift heavy paddle type mill to realize compacting of loosening the soil.In use, in order to ensure the compacting quality to basis, during some region of compacting, lift heavy is typically required for certain quantity guarantee of ramming and tamps quality this dynamic compaction machinery.But, there are some engineering construction troops, in order to reduce cost, ignore quality and use inferior materials and turn out substandard goods, that reduces lift heavy rams quantity, therefore, in order to make dynamic compaction machinery in use ensure, lift heavy has certain rams quantity, it is necessary to dynamic compaction machinery is rammed position, rams quantity and the time of ramming is monitored, and existing mode is mainly the most manually added up, manually report, inevitable that disorderly the phenomenon of report workload occurs, be unfavorable for engineering construction troop is effectively supervised.
It is therefore desirable to design a kind of monitoring system being applicable to strong rammer operating mode, for being further ensured that the quality of engineering construction provides technical guarantee, also make existing dynamic compaction machinery improve utilization rate of equipment and installations simultaneously, run more safe efficient.
Luo Yunxiang, Duan Longwen, Liu Guoqing. a kind of dynamic compaction machinery tamping pit number detecting system and detection method and dynamic compaction machinery: Shanghai, CN102693449A [P] .2012-09-26.A kind of dynamic compaction machinery tamping pit number detecting system of this disclosure of the invention and detection method and dynamic compaction machinery, it relates to dynamic compaction machinery work data acquisition, the rope stretching amount detecting device being connected with dynamic compaction machinery steel wire rope；The pressure transducer being connected with strong rammer winding motor hydraulic circuit；The elevator direction detection device being connected with strong rammer winding system；That rams with dynamic compaction machinery that controlling organization is connected linkage rams counter switch；One controller, controls device and connects rope stretching amount detecting device, pressure transducer, elevator direction detection device respectively, rams counter switch；The tamping pit number input equipment that one is connected with controller；One timer being connected with controller.The invention has the beneficial effects as follows: maloperation can be prevented, improve the accuracy of tamping pit counting, and then improve the work efficiency of strong rammer operation；Save human cost；Accuracy of detection is high, and error is little, and reliability is high, low price；Whole system is easy for installation, and debugging is simple, can be used for various strong rammer equipment.
The shortcoming of this system is as follows:
1) parameter measured is few.Can only metering, it is impossible to measuring hammer ram weight, i.e. hammer ram weight is the most qualified does not knows.Such as a kind of hitting several sampling switch structure [Application Number (patent): CN201120321035.7] magnetic switch and being used for touching the displacement mechanism that the magnet steel and of magnetic switch action can drive magnet steel limited distance to move back and forth for dynamic compaction machinery, the counting assembly [Application Number (patent): CN201220081804.5] of a kind of dynamic compaction machinery and strong rammer ramming times use detection module and using stay cord to the pulling force of detection module as trigger source；Or signal is big by the degree of external interference, such as a kind of remote pounding number monitoring system for dynamic compactor [Application Number (patent): CN201110251649.7], only with magnetic switch；A kind of ram counting assembly [Application Number (patent): CN201020693421.4] data acquisition module based on machinery for strong rammer operation, including pedestal, compress reset assembly and counter switch.
2) cost is high, is difficult to large-scale popularization application.
3) easily affected by temperature, humidity, dust etc., be not suitable for adverse circumstances.
