Abstract
The utility model relates to a pile-soil load sharing ratio measuring device, which comprises a steel support, an organic glass cylinder, an aluminum alloy steel tube, a pile cap, a foam layer, sandy soil layers and an electronic platform scale. The cylinder is fixed onto the steel support; the electronic platform scale is placed below the cylinder; the aluminum alloy steel tube is mounted in the cylinder and contacts with the electronic platform scale; the pile cap is arranged at the top of the aluminum alloy steel tube; the foam layer is mounted on the periphery of the aluminum alloy steel tube so as to simulate settlement of a soft soil base; and silicone grease films are additionally arranged on the inner lateral wall of the cylinder and the outer lateral wall of the aluminum alloy steel tube so that friction force is decreased. At least 1-10 sandy soil layers are additionally arranged on the upper portions of the aluminum alloy steel tube and the foam layer, numerical values of the electronic platform scale and compressive deformation of foam are read out, and pile-soil load sharing ratio can be computed according to the weight of each sandy soil layer and can be adjusted by changing the size of the pile cap and the diameter of the cylinder, so that basis is provided for design. The pile-soil load sharing ratio measuring device has the advantages that settlement of the soft soil base can be simulated by measuring the pile-soil load sharing ratio, so that the basis is provided for design.
Description
Technical field
The utility model relates to a kind of native load share ratio determinator.
Background technology
The foundation pile of existing building is to connect design by measuring soil property, and design is not very accurate like this, needs the schematic design by the safety factor maximum.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of native load share ratio determinator.
To achieve these goals, the present invention adopts following technical scheme:
The native load share ratio determinator of stake, it is by steel bracket, the organic glass cylinder, the aluminium alloys steel pipe, pile cover, froth bed, sand layer and electronic platform scale are formed, cylinder is fixed on the steel bracket, electronic scale places the cylinder below, the aluminium alloys steel pipe is installed in the cylinder and with electronic platform scale and contacts, top at the aluminium alloys steel pipe is provided with pile cover, froth bed is installed around the aluminium alloys steel pipe, sedimentation with the simulation soft foundation, the lateral wall of cylinder inside wall and aluminium alloys steel pipe adds the silicone grease film with the power of reducing friction, add 1-10 layer sand layer at least at aluminium alloys steel pipe and froth bed top, and the reading and the foam compression distortion of reading electronic scale, the native load share ratio of stake can be calculated according to every layer of sand layer weight again, can the native load share ratio of stake can be adjusted by changing pile cover size and drum diameter, for design provides foundation.
The utility model has the advantages that: measure by the native load share ratio of simulation stake, can simulate the sedimentation of soft foundation, for design provides foundation.
