Abstract
A kind of sheet for civil engineering and construction, relate to technical field of civil, comprise core, base material and tablet, tablet is separated with in the middle of ground and core, tablet is made up of base material and release sheet, air inlet is provided with above release sheet, the side that release sheet and base material are close to is with venthole, when core extracted by needs, only need at the air inlet port input air of release sheet, when chamber pressure one timing of release sheet, air can overflow from the venthole release sheet and act on base material, when release sheet internal pressure is enough large, base material and release sheet can produce gap because of the effect of air pressure, and the high-pressure flow of air also can produce air film between base material and release sheet, base material and release sheet contact surface is allowed to reduce, thus reduce friction, release sheet is because being separated with base material between ground, easily core and release sheet can be extracted simultaneously, release sheet is reusable.Both need not king-sized pulling force, the use of sliding agent can be avoided again, convenient and swift, hygienic environment-protecting.
Description
technical field:
The utility model relates to technical field of civil, is specifically related to a kind of sheet for civil engineering and construction.
background technology:
In the Foundation Design of building field or field of civil engineering; the works such as the protection walls preventing from caving in are buried in frequent meeting underground in ground; now the supports such as steel sheet pile are directly embedded in ground by general employing; then; in ground, be pressed into the water such as cement paste or fresh concrete thermosetting composition again, or imbed the H profile steel material as core after making excavated hole injection water thermosetting composition.When carrying out this underground construction more in the future, do not cause waste to make this steel used in Foundation Design or do not cause obstacle, core need be extracted from ground, but the sizable pulling force of process need of withdrawing core from ground or water thermosetting composition, be not easy to implement, also can damage ground and core simultaneously, and sliding agent be used in waste in a large number while also can produce corrosion to ground or water thermosetting composition.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of sheet for civil engineering and construction, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of sheet for civil engineering and construction, comprise core, base material and tablet, a part for core is placed in ground, by tablet, core and ground are separated, described tablet is made up of base material and release sheet and the binding face of base material and release sheet overlaps completely, base material side is attached on ground, base material opposite side is close to release sheet side, release sheet opposite side is attached on core, described release sheet be metal material and release sheet with inner chamber, bearing rib is provided with in the inner chamber of release sheet, release sheet and the base material side of fitting is with venthole and venthole and inner space, release sheet top is provided with an air inlet port.
Venthole on described release sheet should ensure at least to have one in each square decimeter on release sheet surface and the gas outlet number had in every square decimeter is identical, is evenly distributed on release sheet surface.
The diameter of described venthole should control between 0.5cm to 1.5cm.
The beneficial effects of the utility model are: be separated with tablet in the middle of ground and core, tablet is made up of base material and release sheet, air inlet is provided with above release sheet, the side that release sheet and base material are close to is with venthole, when core extracted by needs, only need at the air inlet port input air of release sheet, when chamber pressure one timing of release sheet, air can overflow from the venthole release sheet and act on base material, when release sheet internal pressure is enough large, base material and release sheet can produce gap because of the effect of air pressure, and the high-pressure flow of air also can produce air film between base material and release sheet, base material and release sheet contact surface is allowed to reduce, thus reduce friction, release sheet is because being separated with base material between ground, easily core and release sheet can be extracted simultaneously, release sheet is reusable.Both need not king-sized pulling force, the use of sliding agent can be avoided again, convenient and swift, hygienic environment-protecting.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
With reference to Fig. 1, a kind of sheet for civil engineering and construction, comprise core 5, base material 2 and tablet, a part for core 5 is placed in ground 1, by tablet, core 5 and ground 1 are separated, described tablet is made up of base material 2 and release sheet 3 and the binding face of base material 2 and release sheet 2 overlaps completely, base material 2 side is attached on ground 1, base material 2 opposite side is close to release sheet 3 side, release sheet 3 opposite side is attached on core 5, described release sheet 3 be metal material and release sheet 3 with inner chamber 8, bearing rib 4 is provided with in the inner chamber of release sheet 3, release sheet 3 and base material 2 side of fitting with venthole 7 and venthole 7 be communicated with inner chamber 8, release sheet 3 top is provided with an air inlet port 6.Venthole 7 on described release sheet 3 should ensure at least to have one in each square decimeter on release sheet 3 surface and gas outlet 7 number had in every square decimeter is identical, is evenly distributed on release sheet 3 surface.The diameter of described venthole 7 should control between 0.5cm to 1.5cm.Tablet is separated with in the middle of ground 1 and core 5, tablet is made up of base material 2 and release sheet 3, air inlet 6 is provided with above release sheet 3, the side that release sheet 3 and base material 2 are close to is with venthole 7, when core 5 extracted by needs, only need at air inlet port 6 input air of release sheet 3, when inner chamber 8 pressure one timing of release sheet 3, air can overflow from the venthole 7 release sheet 3 and act on base material 2, when release sheet 3 internal pressure is enough large, base material 2 can produce gap because of the effect of air pressure with release sheet 3, and the high-pressure flow of air also can produce air film between base material 2 and release sheet 3, base material 2 and disengaging 3 contact surfaces are allowed to reduce, thus reduce friction, release sheet 3 is because being separated with base material 2 between ground 1, easily core 5 and release sheet 3 can be extracted simultaneously, release sheet 3 is reusable.Both need not king-sized pulling force, the use of sliding agent can be avoided again, convenient and swift, hygienic environment-protecting.
