Abstract
The utility model discloses a combined pre-buried loading box used for testing the bearing capacity of a pile foundation. The combined pre-buried loading box comprises a reinforced concrete bottom plate, a displacement pole, a displacement pipe and a lifting jack, wherein the reinforced concrete bottom plate is in the shape of a round platform, and the lifting jack is installed on the upper top surface of the reinforced concrete bottom plate in the shape of the round platform. The combined pre-buried loading box solves the problem that a lower load-bearing plate of the loading box is easy to bend and deform, lowers the manufacture cost, and improves the reliability of test data.
Description
Technical field
The utility model relates to bearing capacity of pile foundation test field, specifically is a kind of pre-buried load case of combined type that is used for the bearing capacity of pile foundation test.
Background technology
The load box that the test of pre-buried load box method static load of pile foundation lotus is adopted improves on the load box basis substantially, and in the time of at the bottom of load box is placed on, because the compressibility on stratum, following bearing plate is subject to flexural deformation, thereby influences the reliability of test data; Overcome above-mentioned defective, must thicken bearing plate, thereby manufacturing cost can sharply increase.
The utility model content
The purpose of this utility model provides a kind of pre-buried load case of combined type that is used for the bearing capacity of pile foundation test, has solved the problem of the flexible distortion of bearing plate under the load box, has reduced manufacturing cost, and has improved the reliability of test data.
The technical solution of the utility model is as follows:
The pre-buried load case of combined type that is used for the bearing capacity of pile foundation test includes reinforced concrete floor, displacement bar, displacement pipe, very heavy pre-, and described reinforced concrete floor is round table-like, and the last end face of round table-like reinforced concrete floor is installed with jack.
The taper seat of described reinforced concrete floor is provided with step-like displacement pipe positioning table, and described displacement pipe box is loaded on the top of displacement pipe positioning table, and described displacement bar bottom is resisted against on the end face of displacement pipe positioning table.
The utility model is exerted pressure to the truncated cone-shaped reinforced concrete floor by jack, partial pressure is diffused into the reinforced concrete floor bottom by the truncated cone-shaped reinforced concrete floor, make its bottom stressed evenly, reduce deformation of bottom, intensity uprises, and has reduced manufacturing cost, save steel more than 60%, owing to adopt the truncated cone-shaped reinforcing bar to mix the earth base plate, during test, make the influence of base plate lateral resistance be reduced to minimum simultaneously.The utility model has improved the reliability of test data.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the mounting structure schematic diagram of displacement bar of the present utility model, displacement pipe.
The specific embodiment
Referring to accompanying drawing, the pre-buried load case of combined type that is used for the bearing capacity of pile foundation test, include reinforced concrete floor 1, displacement bar 2, displacement pipe 3, jack 4, reinforced concrete floor 1 is round table-like, the last end face 5 of round table-like reinforced concrete floor is installed with jack 4, junction plate 6 is installed on the jack 4, the taper seat of reinforced concrete floor 1 is provided with step-like displacement pipe positioning table 7, displacement pipe 3 is set in the top of displacement pipe positioning table, and displacement bar 2 bottoms are resisted against on the end face of displacement pipe positioning table 7.
Claims (2)
