Description
Technical field:
The utility model relates to a kind of device for detection of foundation pile vertical compression bearing capacity, belongs to foundation pile checkout equipment technical field.
Background technology:
At bridge construction beam or the treatment of soft foundation of roadbed deep layer, according to Department of Transportation's relevant regulations, all must detect the vertical compression bearing capacity of its foundation pile or flexible pile (as: broken stone pile, high-pressure rotary jet grouting pile, deep-mixed pile etc.), to guarantee to be open to traffic bridge and the soft base energy of roadbed safe operation afterwards.When building Bridge Piles or roadbed flexible pile vertical compression loading test, normally adopt direct method (ballast platform method, anchored pile-testing method) and half direct method (self-balancing approach) to detect at present, but due to the restriction of building-site objective condition, the frequency of utilization of direct method is higher than half direct method.In direct method, the application with ballast platform method is more extensive and traditional again, although traditional ballast platform method has been a kind of detection technique of maturation, can detect foundation pile vertical compression bearing capacity, but in the practical application of building-site ballast counter-force platform still exist below some problems:
1, there is larger potential safety hazard.In preloading process, because cannot monitor in time the pressure of each strong point changes, can cause the foundation instability heap carrier threat detection personnel life security (past, the accident that heap carrier collapses and causes casualties occurred in the test in a lot of provinces) of collapsing;
2, Test Field data are disturbed greatly by extraneous factor.Conventional detection devices non-fixed power, is used building-site power supply more, often can be because during accidental power failure causes test to interrupt.Test is interrupted impacting detecting data;
3, cannot directly calculate preloading weight.Heap carrier cannot directly be calculated quality, can only measure after heap carrier bulk by use, then with volume, be multiplied by the method calculating preloading weight of heap support density, and the preloading weight of calculating like this and actual mass exist larger error;
4, ballast counter-force platform is installed, is dismantled and transportation inconvenience, and testing efficiency is low.The installation of ballast counter-force platform platform, dismounting and a large amount of man power and material of traffic requirements consumption, be installed to dismounting off-test and transport construction plant from the construction plant that enters of equipment, need to expend a large amount of time;
5, platform shape is single, bad adaptability.The girder steel that ballast counter-force platform is used is fixed dimension, when being subject to building site extreme terrain restriction, cannot use;
6, checkout equipment is without stablizing long-term electric supply installation.Building-site natural conditions are severe, when power supply facilities mostly is zero, set up, and power discontinuous, usually have a power failure, and spread of voltage, directly use meeting causes damage to plant and instrument.
For overcoming the deficiency of existing ballast counter-force stage apparatus, provide the utility model.By literature search, have no the open report identical with the utility model.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of existing ballast counter-force detection of platform device, and a kind of device for detection of foundation pile vertical compression bearing capacity is provided.
Device for detection of foundation pile vertical compression bearing capacity of the present utility model, is characterized in that device should consist of test platform parts and test transporter components; Wherein:
A. test platform parts are mainly by hollow high-strength steel king-post (2), each connecting portion is used strengthens personnel's entrance overhead gage (1) that angle steel (3) is linked in sequence above high-strength steel king-post (2), the lifting platform system (4) being connected with data line and power line (12) with lifting platform support (9) respectively, respectively with first order extensible canopy (5), second level extensible canopy (6), the detection of platform girder steel telescopic system (11) that platform support (7) is connected with data line and power line (12), and be connected to personnel's entrance lower baffle plate (10) of high-strength steel king-post (2) below, the load measurement system (8) being arranged between platform support (7) and ground forms,
B. test transporter components mainly by for transport detection platform vehicle body, be placed on vehicle body for checkout equipment and various test-meter provide the electric supply system (13) of safety and stability, and in the needed various data acquisition instrument of test are installed and provide the instruction carriage driver's cabin (14) of interim office and resting space to form.
Product and material that the utility model adopts market to buy are reequiped according to a conventional method or prepare.
Compare with existing equipment, the utility model has the advantage of:
1, security performance is high.In preloading process, can directly monitor the pressure changing of each strong point, adjust in time the center of gravity of heap carrying platform and quality and the preloading position of heap loading, can effectively avoid piling carrier and collapse, reduce the potential safety hazard in whole process of the test;
2, detection data reliability is higher, and testing efficiency is high.The utility model platform is provided with the device that can stablize long-term power supply, can effectively avoid the test causing due to building site during accidental power failure to interrupt.For testing staff has designed designated lane, can avoid because testing staff installs the artificial disturbance that instrument turnover platform causes, accurate data recording equipment is arranged in the interim office in inspection vehicle driver's cabin, can effectively avoid the factors such as extraneous weather and temperature to detecting the interference of data.In whole test testing process, the utility model platform has reduced a large amount of personnel and mechanical making time, compares same category of device operating efficiency higher;
3, can directly calculate preloading weight.By the apparatus for measuring quality on each strong point of platform, can measure preloading weight accurately, for test provides reliable and stable test counter-force, avoid occurring not making counter-force platform by the situation of jack stand because preloading amount does not meet code requirement;
4, simple in structure, mount and dismount simple and easy to do.The utility model is a flexible device of volume, mount and dismount simple and easy to do, without using the auxiliary installing/dismounting of heavy mechanical equipment;
5, building-site is adaptable, can be combined into the platform of various different area and shape.The equal flexible distortion of detection girder steel that the utility model platform is used, can, by the combination of the different collapsing lengths of girder steel, install the platform that is deformed into difformity and different area.Not limited by building site extreme terrain, compare same category of device adaptable;
6, can be for Site Detection personnel provide good work and rest environment, can allow the hommization more of whole testing process.Because test period reaches more than 30 hour, building-site natural conditions are severe, testing staff often will be in high temperature and heating summer or low temperature severe cold the recording detection data of staying up late on duty.The utility model platform can provide the interim office that can becalm and take shelter from rain for Site Detection operator on duty, testing staff's rest of normally working in office, can also keep in touch by computer and wireless network and the external world, compare the hommization more of same category of device testing process.
