Description

Civil engineering Integral Steel based platform static test preloading device

Technical field

The utility model relates to be related to static-loading test ballast counter-force when a kind of civil engineering pile detection to make Device, especially a kind of civil engineering Integral Steel based platform static test preloading device.

Background technique

Static-loading test ballast counter-force is mainly from 1, anchorage pile, anchor pole at present；2, artificial preloading；3, it utilizes The frictional resistance (self-balancing load box) of test pile itself.But since site condition limits, anchorage pile or anchor pole cannot construct, certainly flat Load box weigh also due to pile body frictional resistance is far smaller than the reasons such as bottom bearing, using being also restricted.Artificially face pressure preloading base again It is not influenced by site condition and pile body itself frictional resistance and bottom bearing ratio in sheet, is adopted extensively in static-loading test With the mode of ballast preloading at present has sand pocket, stone bag, earth bag, water bag, sandbox, stone case, native case, water tank, metal material, concrete Prefabricated component, the rectangular slab of stone, block stone have tank column accumulation load method again recently.These preloading modes carry the vertical compression of ground and pile foundation Power test has played important function.But with the rapid advances of China's manufacturing industry level, ground and pile foundation construction are mechanical horizontal Raising rapidly, especially big machinery emerge in large numbers, and civil engineering tall and bigization, the two require ground and bearing capacity of pile foundation ton in addition Position greatly improves.Current large-tonnage loading test difficulty is big, costly, and some bearing capacity of single pile majorities reach several hundred tons, on Kiloton even thousands of tons of.Existing country's pile measurement specification regulation can be carried when condition does not have with drill core test pile foundation Power.Actually core drilling method at all can not detection of pier foundation bearing capacity, deduction bearing capacity of pile foundation is only carried out according to correlated condition, strictly On say that this is not very not scientific also rigorous.But sorry is that the loading test of current domestic many large-scale pile foundations in place generallys use brill The detection of core method.It is difficult to be primarily due to top heap carrying capacity preloading, prior art economic condition is unable to reach, second is that because large-tonnage Very high to platform bearer power and platform buttress foundation requirement, platform bearer power is easy to solve by Steel Structural Design, and platform Buttress ground solves difficulty, and detection scene is often disturbed soil, and bearing capacity is smaller, therefore requires foundation soil under detection device Height needs to carry out special disposal and is just able to satisfy test requirements document, and each testing site needs to handle, and time-consuming and laborious and cost is too high.

And after the completion of each testing site, need to install second platform in advance, waits on first testing site platform Ballast be transferred on second platform after, secondary beam, girder and buttress etc. on first test platform could be removed, remove After be pre-installed on third testing site.Ballast after to second testing site on second point turns to try in third It tests on platform.The continuous transfer that platform and buttress girder, heap loading are constantly carried out with this, until on-the-ground test point all tie by detection Beam.

The transfer work of the ballast between testing site can be greatly reduced with water load, but not can be reduced static test Buttress, girder, secondary beam and water containing device installation, dismantlement work and buttress, girder, secondary beam and water containing device transfer work.

Since the structure of existing static-loading test ballast heap carrying platform is to be placed on testing site by jack Girder places the platform that secondary beam is constituted on girder, platform both sides setting buttress support platform weight and allow platform to keep steady It is fixed, the preloading ballast on platform.It is therefore seen that girder and buttress are in together below platform, and as finder charge increases, girder Accordingly become larger with secondary beam section, because girder test carry out when will bear platform on heap loading weight, then by weight pass through with The jack of any is concentrated to pass to testing site on girder, in order to allow girder and secondary beam anti-bending strength to keep good, it is necessary to increase Height is to maintain girder not to be bent (bending resistance and main depth of beam of girder are at 2 power relationships) when by jack pushing tow And then mounting height also increases with it, buttress must also be increased to adapt to the installation of girder.That is, finder charge is bigger, Girder must just increase adaptation load, in order that achieving the purpose that bending resistance, and as girder increases, in order to install girder with regard to necessary Increase buttress, the buttress increased causes platform further to be raised again, and originally on platform the load height of preloading with tonnage Increase is also increasing, and then whole center of gravity is got higher, and becomes top-heavy state, stability decline.In other words, finder charge Heavier, entire platform is higher, and stability is poorer, and building operation amount increases, and testing cost increases, and detection time increases Long, also high to buttress foundation requirement, buttress ground generally requires just to can be carried out buttress installation after carrying out special basement process, not so Foundation pressure concentration can settle at buttress, directly affect platform in balance, and then platform inclination is caused to cause safety accident.However, For safety, heavier platform more needs to stablize, it is clear that the prior art has implacable contradiction on this problem. Buttress height wastes valuable buttress preloading space simultaneously, this point is more important to large-tonnage preloading.Currently in order to reducing buttress Highly, girder is done it is short, girder do it is short after Lack of support when again horizontal direction spell plus girder, and cause main beam stress unreasonable It is not scientific.The problem of tank column method preloading needs the long period there is also buttress cost issues and installation buttress.

The ballast preloading of existing each testing site requires to carry out lifting buttress, platform and construction to build, and test is completed Afterwards, it is necessary to carry out ballast preloading lifting unloading, then remove platform.Regardless of next testing site is apart from a upper testing site distance How is distance, also to repeat the above steps, and also needs Automobile Transportation in field when apart from farther out, also very numb when testing site is close Tired, the platform of first testing site may influence building for second platform, so ballast and buttress, platform must be hung It opens, then hangs again and buttress could be installed back, builds platform, last preloading ballast.It hangs and turns or under running in platform removal A testing site also needs to repeat the build process of above-mentioned test platform.The disadvantage is that: each testing site requires to build and tear open Except test platform, loads and unloading ballast load, time-consuming and laborious increase testing cost, extend project at growth detection non-cutting time Duration.And if differential settlement occurs for platform ground, platform is easily tilted, and the test platform built is granular media formula structure, is not had There is method that can adjust the balance of platform, in addition to being removed, can only just be allowed to tilt.In the case where failing to remove in time, such as Fruit platform quick slant, heap, which is loaded in the load on platform and must will cause, to collapse, so that safety accident occur.And for vertically resisting Press the ballast load of static test institute preloading, usually hundred tons to kiloton or even a few kiloton rank.Weight is quite surprising, once Safety accident occurs, consequence is extremely serious.

Crane and transport vehicle are frequently used during test, discharges exhaust gas and fugitive dust, pollute air and environment.

Therefore, preloading device existing defects used by existing static-loading test, need to improve.

Utility model content

The purpose of the utility model is to provide a kind of energy save the costs, shorten detection non-cutting time, and exclude large-tonnage lotus Carry preloading security risk and environmentally protective civil engineering Integral Steel based platform static test preloading device.

The basic conception of the utility model is: changing existing artificially face pressure preloading mode again, buttress is cancelled, using steel Structure basis increases the horizontal area of steel structure base, and shape increases the contact area with ground similar to steel construction plate, will be upper Portion's preloading load is distributed on ground as big as possible, greatly reduces foundation soil stress.Steel structure base vertical structure uses Box beam or fashioned iron, horizontal direction structure use steel plate or steel construction plate, horizontal steel can also do not had to when vertical structure horizontal space is small Structural slab.Horizontal and vertical steel structure connection is at an entirety, and single component maximum physical dimension is controlled by traffic condition, structure Size need to be designed specially.

Increased using foundation area after steel structure base, testing load can be deposited on steel structure base, such steel knot Structure basis just instead of original heap carrying platform and buttress, forms a steel structure base platform being placed directly on ground.It is main Beam is placed on steel structure base center, and mounting height is controlled by very heavy heights of roofs and testing site designed elevation.In order to steel knot Load on the basis of structure passes on jack and testing site, effectively connects between girder and case base basis.Main depth of beam etc. is cut Face size influences very little to pilot system, only influences girder volume size ballast and stacks space, so girder can be done more Height, girder work stress are more reasonable.

Steel structure base plays the platform action for stacking ballast again for top, actually plays basis and platform Fuel tank, oil pipe, oil pump and motor and circuit etc. can be set in platform, hydraulic control is provided with outside platform for double action Platform and hydraulic moving mechanism device processed, Platform center plate center are additionally provided with jack storehouse and place jack.Jack after stage+module is good Upper accessible girder center, it is lower can be according to pushing testing site rigidity pressing plate center.Therefore steel structure base may be simply referred to as base steel platform, Its component parts is referred to as base steel platform board.

Heap loading directly passes through base steel platform and is placed on foundation surface, and is responsible for the girder of stress by being located at base steel platform Top (flatness that girder does not influence base steel platform platform Yu foundation surface contact surface), and pass through fixed connecting part for base steel Platform connect with girder (fixed connecting part links together girder and base steel platform, and static test carry out when receiving The weight of heap loading), it presents under stress and allows state of the base steel platform hanging on girder (girder can be by being attached to The beam that increases between girder and base steel platform is increased, and increases the weight that beam only needs to bear girder, because of static test When progress, girder is by the reversed pushing tow of jack, and the weight of heap loading is by the fixed connecting part that connect with girder and base steel platform It bears, thus increases beam when static test carries out, the girder weight born instead can become smaller.After increasing girder, jack peace Can be more loose between emptying, and other loose spaces can more effectively be utilized, such as setting detection instrument, adjustment benchmark Beam etc.).Girder center lower end directly contacts and (certainly when necessary, can also be fixedly connected) jack, allows the pushing tow of jack End is matched across base steel Platform center through-hole with the test dot center for being exposed to foundation surface.When the pushing end of jack is opened When beginning pushing tow tests dot center, jack is subject to the girder barrier force directly contacted with jack, and the barrier force of girder Again from the base steel platform for the receiving heap loading weight being firmly connected with it, and then the weight of heap loading is allowed successively to pass through base steel Platform, the fixed connecting part of base steel platform and girder, girder, jack, most the pushing end through jack loads on test afterwards On the rigidity pressing plate of dot center.Before the pushing end of jack starts the rigidity pressing plate of pushing tow test dot center, base steel platform It is directly placed at foundation surface, eliminate causes heap loading to be collapsed a possibility that causing the accident because of buttress unbalance stress.Secondly, It is more convenient that preloading object is lifted on base steel platform, i.e., the ballast heap carrying platform the low more is conducive to the fast hoisting of heap loading, It not only saves the time, can more effectively reduce cost.In addition, the base steel platform being directly placed on ground, due to contact ground Area is significantly increased compared with buttress, i.e. the pressure of unit area accordingly reduces, and the requirement to ground is also greatly reduced, that is, does not have to as existing Have needs to do ground special disposal before building buttress, has not only saved expense and time, but also more consolidate durable.Directly place Base steel platform on ground reduces whole height of C.G., and in the case where same stack loading capacity, detection device is safer.It puts The base steel platform on ground is set, huge heap loading capacity can be distributed on bigger ground, ground stress is small, facilitates progress Big position tonnage preloading provides reliable ground guarantee to the static test of current large-scale pile foundation, is conducive to civil engineering large size Static test summary can directly carry out static test detection to large-scale pile foundation, and national pile measurement specification regulation pair at present Large-scale pile foundation can detect large-scale bearing capacity of pile foundation detection with indirect methods such as core drilling methods, this is very not scientific also not rigorous.But it loses Regret is that the loading test of current domestic many large-scale pile foundations in place generallys use drill core test.

This structure also has the advantage that, it is only necessary to one of examination in multiple testing sites (test point) in a building site It tests and a little builds device for the first time and tested, and other testing sites do not need to remove device after building device for the first time and completing test It is shifted and is built again, that is, needed when next testing site is tested, it is only necessary to which the device for building completion for the first time is whole It is moved to next testing site.Its main feature is that each project march into the arena after be an entirety after preloading platform building, no longer Installation is removed once in each testing site, saves a large amount of detection non-cutting times and testing cost, and safer.Relative to existing granular media For formula static test preloading mode, the utility model Integral Steel based platform static test preloading device can be saved significantly Installation, disassembly cost, and heap loading collapse accident caused by capable of effectively avoiding because of platform inclination.It can even build At stage apparatus on the outside of existing hydraulic moving mechanism running gear is installed, allow its stabilization to be moved to next testing site.Wherein, hydraulic step Mobile steel based platform can not only be stablized by fulfiling walking apparatus, and can appropriateness play the role of adjust base steel platform in balance, enable steel Based platform is more stable.The present apparatus be able to achieve static load platform overall movement, thus reduce each testing site platform building and Dismounting and energy automatic moving, to reduce the platform transfer work that crane or transport vehicle are completed.If using tank column ballast heap Load method is first vented the water in tank column, and base steel platform can be moved together with slack tank cylinder, if middle-size and small-size loading test, platform It can also be moved together with ballast, without removing platform, mounting platform, lifting machine, personnel can be saved, more with complete off-load It is important that a large amount of detection times can be saved, accelerate detection progress, save project duration, reduction device, which removes installation and turns to hang, to be turned A possibility that safety accident occurs during fortune.The hydraulic vertical prop lifting platform height of platform adjusts plateau levels degree, if Platform inclination can carry out well straightening to platform, enable platform trouble free service.The transfer of platform is not required to crane and transport between testing site Vehicle can rely on hydraulic moving mechanism walking chassis automatic moving.If platform heap carrying capacity is very big, after fractional load can be shed when mobile Integrated moveable again, this mode are suitable for the preloading stage apparatus of kiloton or more.Levelling function: this stage apparatus can pass through Hydraulic moving mechanism walking mechanism adjusts the balance of platform entirety, can not only prevent platform inclination by adjusting said mechanism, moreover it is possible to It tilts under inevitable extreme case, effectively extends the platform inclination time by adjusting said mechanism, to win to the full extent The time of disassembly ballast load is taken, to avoid collapsing, guarantees platform safety, eliminates security risk.
