According to the improved engineering pile static load surcharge-load-type testing device, the maximum load can reach 24,000kN, and simultaneously, the limit of a single set of 6,000kN load test hanger rod can be solved; and according to demands, the quantity of the hanger rods is increased, and the hanger rods can be respectively combined into two sets of independent engineering pile static testing devices with the load of 12,000kN. The device disclosed by the utility model has fewer separable accessories, is simple and convenient, is easy to assemble and disassemble, and is safer.
Description
Technical field
The utility model relates to a kind of civil engineering work pile foundation 3000kN～24000kN load static test device.
Background technology
Along with the urban construction high speed development; Use
drilled pile according to construction quality engineering piles universal demand; And
engineering piles requirement test sanction lotus is 8000kN～20000kN; China's Coastal Areas is generally used concrete prefabricated briquetting preloading formula reaction frame at present; Its load is generally below 6000kN; Generally adopt the spell shape formula of loosing greater than the 6000kN static test; Its complicated operation; Discrete is many, and experimentation cost is higher.
Confirm that at present both at home and abroad the bearing capacity of single pile method is a lot, total is divided into two big types: the first kind is that the engineering site test pile is carried out static load test and power detection, and second type is through other means, draws respectively to calculate behind end resistance and the pile body collateral resistance to try to achieve.One of fundamental purpose of pile testing is to confirm bearing capacity of single pile, and single pile vertical static load load test be the detection single pile load of generally acknowledging the most intuitively, method the most reliably.
Summary of the invention
The purpose of the utility model provide a kind of need not increase the outer extra concrete pad of load, discrete few, simple and convenient, be prone to adorn readily removable engineering piles static load preloading formula test unit.
The purpose of the utility model realizes through following technical scheme.
A kind of improved engineering piles static load preloading formula test unit; It is characterized in that: said test unit comprises undercarriage, puts on the shelf, static load beam, central sill, suspension rod, cushion block, concrete briquetting and lifting jack, and the static load beam is between undercarriage and central sill, and static load beam both sides are provided with cushion block; Through laying of cushion block and central sill; Make the level of putting on the shelf place above the central sill, suspension rod is installed in undercarriage and the draw-in groove of putting on the shelf, on the concrete briquetting is positioned at and puts on the shelf.
One end of said suspension rod is provided with cross-arm.
The utility model compared with prior art has the following advantages.
The utility model engineering piles static load preloading formula test unit guarantees that through undercarriage and the combination of static load beam static load beam and stake end have 600mm clear space distance, need not increase the outer extra concrete pad of load.The utility model engineering piles static load preloading formula test unit peak load can reach 24000kN, also solves the restriction of single cover 6000kN load test suspension rod simultaneously.Increase suspension rod quantity as requested, can it be combined into the independent load of two covers respectively is 12000kN engineering piles static test device.Its discrete is few, simple and convenient, it is readily removable and safer to be prone to adorn.
Description of drawings
Fig. 1 is 2400 tons structural representation for the utility model engineering piles static load preloading formula test unit load;
Fig. 2 is 1200 tons structural representation for the utility model engineering piles static load preloading formula test unit load;
Embodiment
Below in conjunction with accompanying drawing the utility model engineering piles static load preloading formula test unit is described in further detail.
Like Fig. 1 and shown in Figure 2; The described engineering piles static load of the utility model preloading formula test unit mainly by undercarriage 101, put 102 on the shelf, static load beam 103, central sill 104, suspension rod 105, cushion block 106, concrete briquetting 107 form with lifting jack 108; Static load beam 103 is between undercarriage 101 and central sill 104, and static load beam 103 both sides are provided with cushion block 106, through laying of cushion block 106 and central sill 104; Make that 102 levels of putting on the shelf place above the central sill 104; Suspension rod 105 is installed in undercarriage 101 and 102 the draw-in groove of putting on the shelf, and concrete briquetting 107 is positioned at puts on the shelf on 104, and an end of suspension rod 105 is provided with cross-arm 109.The installation and the method for application of engineering piles static load preloading formula test unit are following: according to random sampling stake position; To carrying out necessary floor treatment around the need test pile; (if the test of casting concrete bed course possibly not done the proper technology processing) treats that testing equipment is in place with undercarriage after in place; And guarantee the shared land area of undercarriage physical dimension center and aligned by the test pile center, the static load beam is installed in the undercarriage top, require to align with pile center to be tested in the beam.It is errorless that inspection undercarriage, static load beam and test pile relative position to be detected are confirmed, can carry out cushion block and central sill installation on the undercarriage face, and central sill installs can be in place with putting on the shelf, and suspension rod is installed in undercarriage and the draw-in groove of putting on the shelf in.Above-mentioned installing can be installed the concrete briquetting according to the load needs on last body panel, can carry out the test pile static test when reaching after load requires.
