Abstract
The utility model relates to a underground diaphragm wall static test device which includes a pressure girder (2), hydraulic jacks (3) and a reverse girder, and is characterized in that the lower end surface of the pressure girder (2) is arranged on the upper end surface of the diaphragm wall (1); at least two hydraulic jacks are evenly arranged between the upper end surface of the pressure girder (2) and the lower end surface of the reverse girder along the length direction range of the upper end surface of the diaphragm wall; the load is arranged on the upper end surface of the reverse girder. The underground diaphragm wall static test device has the advantages of simple structure, convenient application, solving the problem that no underground diaphragm wall static test device exists in the prior art and particularly solving the problem that a plurality of hydraulic jacks can be evenly arranged along the length direction range of the upper end surface of the diaphragm wall, so as to apply loads on the super-long and super-wide underground diaphragm wall (such as the diaphragm wall with the width from 5m- 8m) continuously and evenly.
Description
Technical field
The utility model relates to building, municipal works field, relates in particular to diaphram wall static test device.
Background technology
At present, pile foundation was carried out a large amount of static tests, also have very thorough and understanding clearly to the stressed mechanism of pile foundation vertical, but underground diaphragm wall was not carried out static test, vertical applied force mechanism to underground diaphragm wall especially super-long and super-wide diaphram wall is not carried out deep analysis and research, because the vertical bearing capacity to underground diaphragm wall does not all carry out static test, therefore, there is not diaphram wall static test device yet, at present, just traditional pile foundation is carried out static test, but pile foundation is a garden shape section only is equivalent to one " point ", and diaphram wall is the rectangle section, is the wide diaphragm wall of 6-8m to length especially, there is not corresponding static test device
The utility model content
The purpose of this utility model is the deficiency at the above-mentioned background technology, load face length, the scale of construction is big or tonnage is high, area is a big difficult problem at the diaphram wall static test, propose a kind of diaphram wall static test device that is suitable for detecting the diaphram wall vertical bearing capacity.
For achieving the above object, the utility model adopts following technical scheme: diaphram wall static test device, comprise and press beam 2, hydraulic jack 3, reversed beam, it is characterized in that described pressure beam 2 lower surfaces are placed on diaphragm wall 1 upper surface, along evenly being provided with at least two hydraulic jack in the length direction scope of diaphragm wall upper surface, load is positioned on the reversed beam upper surface between pressure beam 2 upper surfaces and reversed beam lower surface.
Described reversed beam can be made of main reversed beam 4 and time reversed beam 5 cross arrangements.
Described pressure beam 2, main reversed beam 4 and inferior reversed beam 5 can adopt steel construction, reinforced concrete structure or pre-stress concrete structure.
Described pressure beam 2 lower surfaces preferably cover the diaphragm wall upper surface.
The utility model is simple in structure, easy to use, solved the problem that does not have diaphram wall static test device at present, especially by along in the length direction scope of diaphragm wall upper surface several hydraulic jack being set evenly, can be to super-long and super-wide diaphram wall (diaphragm wall wide) load application equably continuously as 5-8m.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model comprises presses beam 2, hydraulic jack 3, reversed beam, and described reversed beam can be made of main reversed beam 4 and time reversed beam 5 cross arrangements, also can be made of the cross arrangement of multilayer beam.Described pressure beam 2 lower surfaces are placed on diaphragm wall 1 upper surface, and diaphragm wall 1 upper surface covered, along evenly being provided with at least two hydraulic jack 3 in the diaphragm wall 1 upper surface length direction scope, load 6 is positioned on the reversed beam upper surface between pressure beam 2 upper surfaces and main reversed beam 4 lower surfaces.
Above-mentioned pressure beam 2, main reversed beam 4 and inferior reversed beam 5 can adopt steel construction, reinforced concrete structure or pre-stress concrete structure.
