Abstract
The utility model discloses a kind of moveable static loading test pile cover, comprise concrete body, be embedded in some reinforcing bars of this concrete body inside and some layers of reinforced mesh, entangle the metal casing of this concrete body surrounding, be connected with this concrete body and for the handle lifted, the iron plate of upper surface that is connected to this concrete body, the horizontal parallel interval of these reinforced mesh described is arranged, this concrete body has the smooth soffit for abutting against with pile body.Pile cover is removable to be reused, and saves the duration, easy to use, cost-saving.This concrete body is connected handle, conveniently lifts pile cover.Metal casing entangles this concrete body, greatly can strengthen the anti-pressure ability of pile cover.The upper surface of this concrete body is provided with iron plate, is born the pressure of hydraulic jack, then power is reached concrete body by iron plate, makes whole pile cover uniform force, improves the reliability of test.
Description
Technical field
The utility model relates to a kind of moveable static loading test pile cover, particularly relates to the removable pile cover used in a kind of large-tonnage static loading test process.
Background technology
Static-loading test be detect at present pile bearing capacity the most directly, the most reliable method.It can obtain necessary settling data in Pile Foundations Design process, for design provides a rationally reliable bearing capacity foundation.
For large-tonnage static loading test, higher vertical load and eccentric load often will be born in pile crown position, because load causes too greatly pile crown to destroy and termination test when loading for preventing test, engineering generally can build pile cover on concrete pile head.Before doing pile cover, first should chisel out loose crushing layer and the low strength concrete at a top, expose main muscle, after rinsing well, pour into a mould pile cover again.But, following problem can be there is in the process of the test of traditional static loading test pile cover:
One, before test, soil excavation unnecessary around test pile is needed to fall, chisel out loose crushing layer and the low strength concrete on test pile top again, on test pile, pile cover is built after rinsing well, pile cover needs again the concrete strength of pile cover by the time to reach requirement after building just can carry out static-loading test, has influence on the construction speed of whole engineering.
Two, every root test pile all needs to arrange separately a pile cover, and usually can carry out cutting stake after finishing static loading test, the cost of test is high.
Three, the stake footpath of large-tonnage static loading test test pile is general all larger; usually can because of not controlling verticality well when building pile cover; the axle center of pile cover is caused not overlap with the axle center of test pile; during actual tests, stake top may be subject to the effect of eccentric moment; test pile is made to be in disadvantageous stress; easily pile crown pressure break, affect result of the test.
Utility model content
The utility model provides a kind of moveable static loading test pile cover, which overcomes the deficiency existing for background technology.The utility model solves the technical scheme that its technical problem adopts:
A kind of moveable static loading test pile cover, comprise concrete body, be embedded in some reinforcing bars of this concrete body inside and some layers of reinforced mesh, entangle the metal casing of this concrete body surrounding, be connected with this concrete body and for the handle lifted, the iron plate of upper surface that is connected to this concrete body, the horizontal parallel interval of these reinforced mesh described is arranged, this concrete body has the smooth soffit for abutting against with pile body.
Among one preferred embodiment: concrete strength grade >=C30 that described concrete body adopts.
Among one preferred embodiment: the concrete strength grade that the concrete strength grade that described concrete body adopts adopts than pile body exceeds 1-2 grade.
Among one preferred embodiment: interval 100-300mm between adjacent two-layer reinforced mesh.
Among one preferred embodiment: interval 200mm between adjacent two-layer reinforced mesh.
Among one preferred embodiment: described reinforcing bar is connected with these reinforced mesh.
Among one preferred embodiment: this iron plate is embedded in the middle of this concrete body.
Among one preferred embodiment: the quantity of described handle is two, is connected to the left and right sides of this concrete body symmetrically.
The technical program is compared with background technology, and its tool has the following advantages:
Pile cover of the present utility model may root need to be placed on need test pile body on, and can remove after the experiment has been completed and reuse, save the duration, easy to use, cost-saving.This concrete body is connected handle, conveniently lifts pile cover.Metal casing entangles this concrete body, greatly can strengthen the anti-pressure ability of pile cover.The upper surface of this concrete body is provided with iron plate, is born the pressure of hydraulic jack, then power is reached concrete body by iron plate, makes whole pile cover uniform force, improves the reliability of test.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 depicts the schematic diagram of a kind of moveable static loading test pile cover of the utility model.
Fig. 2 depicts the cross-sectional schematic along A-A line in Fig. 1.
Fig. 3 depicts the pile cover shown in Fig. 1 and is placed in schematic diagram on pile body.
Detailed description of the invention
Please refer to Fig. 1 and Fig. 2, the moveable static loading test pile cover of one of the present utility model, comprise concrete body 20, some reinforcing bars 20, some reinforced mesh 30, metal casing 40, two handles 50 and iron plate 60.
This concrete body 10 has smooth upper surface 12 and soffit 14.Soffit 14 is for abutting against with pile body.Concrete strength grade >=C30 that described concrete body 10 adopts.Preferably, the concrete strength grade that the concrete strength grade that described concrete body 10 adopts adopts than pile body exceeds 1-2 grade.
It is inner that described reinforcing bar 20 and reinforced mesh 30 are embedded in this concrete body 10.These reinforcing bars 20 described vertically states parallel interval are arranged.The horizontal parallel interval from top to bottom of these reinforced mesh 30 described is arranged, interval 100-300mm between adjacent two-layer reinforced mesh 30.Preferably, interval 200mm between adjacent two-layer reinforced mesh 30.Described reinforcing bar 20 is connected with these reinforced mesh 30.
This metal casing 40 entangles this concrete body 10 surrounding.
Described two handles 50 are connected to the left and right sides of this concrete body 10 symmetrically.Described handle 50 is for convenient lifting.
Described iron plate 60 is connected to the upper surface 12 of this concrete body 10, and preferably, described iron plate 60 is embedded in the middle of this concrete body 10.
Please refer to Fig. 3, during test:
Dig out the earthwork at pile body 001 top, pile body 001 is exposed; Pile body 001 top laitance is cut down and cut flat by the pile crown of pile body 001; Fine sand 002 is spread at pile body 001 top; Looking for the central point of pile body 001, pile cover is placed on fine sand 002, aligns with the central point of pile body 001 in the axle center of adjustment pile cover.After having tested, pile cover 10 can be moved on next root pile body to be tested 001.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited according to this, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
