Description
Technical field
The present invention relates to building pile foundation static loading test device and mounting method technical field.
Background technology
Dead load test on pile foundation is one of important content of pile foundation quality detection.So-called dead load test on pile foundation; Be meant function of use by stake; Apply step by step on stake top respectively axial compression, axially uplift force or in the pile foundation support table bottom surface absolute altitude is consistent locates to apply horizontal force; The sedimentation that the respective detection point of observation stake produces in time, on pull out displacement or horizontal movement, according to the test method of relation (being Q～S curve) judgement corresponding single pile vertical resistance pressure bearing capacity, single-pile vertical orientation anti-pulling capacity or the horizontal bearing capacity of single pile of load and displacement.
It is the counterforce device base that existing dead load test on pile foundation need be built the heavy platform of heap usually, and jack is arranged between counterforce device base and the stake top, on the counterforce device base, places mass such as sand pocket, precast concrete block and makes an experiment.And the counterforce device base all is to adopt the heavy section steel winding to form.Along with highrise building, particularly a large amount of constructions of super highrise building, it is also increasing that static loading test is surveyed the bearing capacity tonnage, and the counterforce device base that need build is also increasing.In the face of the dead load test on pile foundation project of a large amount of thousands of tons of magnitudes, on the counterforce device base, place the traditional method of mass such as sand pocket, precast concrete block, that realizes technically at present is difficult increasing.It at first is the counterforce device base heavy of building; Not only cost is high; Intensity is difficult to reach requirement; Problem on deformation is difficult to solve, and will the counterforce device base of heavy or the large-scale component that make up the counterforce device base be moved very difficulty of building site, and landed cost is high and dangerous.Secondly, make the high material consumption of mass, the waste resource, the loading of mass and cost of transportation are also very high.In addition, load counterforce device structural performance and consequent uncontrollable factor and brought bigger potential safety hazard to test.
Summary of the invention
The objective of the invention is to solve the deficiency of prior art; Provide that a kind of member of building the heavy platform of heap is convenient to make, transportation, can assemble on site the heavy platform of heap, simple in structure, safety, large-tonnage dead load test on pile foundation ballast platform counterforce device that cost of manufacture is low in the building site.The present invention also provides the mounting method of this counterforce device.
The objective of the invention is to realize through following technical scheme:
A kind of large-tonnage dead load test on pile foundation ballast platform counterforce device, this counterforce device is staggeredly stacked to form inverted pyramid shape staged ballast platform counterforce device base by the cuboid steel reinforced concrete load-bearing platen that has frame; Be manufactured with a countersunk head lockhole every steel reinforced concrete load-bearing platen center, four angles of every block of steel reinforced concrete load-bearing platen are 1/4th countersunk head lockholes, the common countersunk head lockhole that forms of four jiaos of amalgamations of four blocks of steel reinforced concrete load-bearing platens; Between the adjacent steel reinforced concrete load-bearing platen of horizontal direction through the spacing connection of snap close; Between the adjacent steel reinforced concrete load-bearing platen of vertical direction through the countersunk head lockhole with bolt or cable wire anchoring, the steel reinforced concrete load-bearing platen that is staggeredly stacked is connect the ballast platform counterforce device base that forms the stiff assembly structure.
The present invention is provided with the static load-bearing bearing of the stairstepping that raises successively from the inside to the outside in staged ballast platform counterforce device base bottom.
A kind of mounting method of large-tonnage dead load test on pile foundation ballast platform counterforce device, its mounting process step is:
1. the ground of static load-bearing bearing will be installed handles smooth;
2. static load-bearing bearing is installed successively;
3. be staggeredly stacked with cuboid steel reinforced concrete load-bearing platen and be assembled into inverted pyramid shape staged ballast platform counterforce device base; Between the steel reinforced concrete load-bearing platen that horizontal direction is adjacent with the spacing connection of snap close, between the adjacent steel reinforced concrete load-bearing platen of vertical direction through the countersunk head lockhole with bolt or cable wire anchoring;
4. dispose the cuboid ballast box in addition, the cuboid ballast box is staggeredly stacked forms ballast platform counterforce device balance weight body on ballast platform counterforce device base.
The length of cuboid ballast box of the present invention is long consistent with steel reinforced concrete bearing platform edges of boards, and width is 1/2nd of a length.Form the staggered from inside to outside symmetry arrangement of each layer of assembly cuboid ballast box of balance weight body, arranging between layer and the layer, half-twist is staggered to laminate.The counterweight material that loads in the cuboid ballast box is solid mass or liquid ballast thing.
The present invention adopts the combination of cuboid steel reinforced concrete load-bearing platen to make up the form of structure of the heavy platform of heap; Scattered cuboid steel reinforced concrete load-bearing platen is convenient to the transportation carrying; It is also very convenient that the heavy platform of heap is built in on-the-spot combination; Both solved the difficulty of transporting heavy platform of large-scale heap or heavy section steel structure, also solved the high of the field fabrication of employing heavy section steel and the difficulty of dismantling the heavy platform construction of huge heap, the very long and cost of duration, and also solved large-scale steel and piled the problem that weighs platform intensity and distortion.Laterally pass through the spacing connection of snap close between the adjacent steel reinforced concrete load-bearing platen; It is fit vertically to have constituted rigid group through bolt or cable wire anchoring; In conjunction with the supporting role of set static load-bearing bearing, can effectively solve uncontrollable factor to detecting the potential threat that safety produces.Adopt the cuboid ballast box directly to load mass such as building waste, earth and constitute balance weight body, reduced loading and cost of transportation, source and the sand material loss waste of mass at building-site.Device of the present invention can utilize mass, on-the-spot quick-assembling to connect on the spot, and steel reinforced concrete load-bearing platen, cuboid ballast box etc. can repeatedly use repeatedly, thereby can practice thrift experimentation cost significantly, increase work efficiency.
Mounting method handy and safe of the present invention, easy to implement.
