Abstract
The invention discloses a testing mould for concrete lining segments. The testing mould for the concrete lining segments comprises a bottom panel, a front end plate, a rear end plate, a left end plate, a right end plate and an upper cover. The front end plate, the rear end plate, the left end plate and the right end plate are connected end to end to define a pouring containing cavity together with the bottom panel, the top of the front end plate and the top of the rear end plate are of circular arc structures, and the upper cover is of a circular arc structure, matched with the top of the front end plate and the top of the rear end plate and buckled to the upper portion of the pouring containing cavity. In this way, the testing mould for the concrete lining segments is manufactured by simulating a production mould and mainly used for meeting testing requirements and testing the workability of C50 concrete, the early strength under steam curing, whether the pressure can reach more than 15 MPa in stripping and whether the manufactured concrete lining segments have raised grain.
Description
Technical field
The present invention relates to the field of chemical building material, particularly relate to a kind of concrete lining pipe piece test mould.
Background technology
China builds underground railway from nineteen sixty-five, along with the continuous expansion of China's subway construction scale, construction of subway technology obtains development, and construction method has developed into the multiple methods such as present cut and cover method, cap excavation method, Mining Method, shield method by originally single cut and cover method and deposited.Wherein shield method is owing to having economy, safety, to ground natural conditions and the advantage such as effect on building is less, the construction period is shorter, being developed rapidly in China's subway construction.Also mainly shield method is adopted in the engineerings such as cross-river tunnel, gas transmission and municipal drainage tunnel.
Section of jurisdiction is the tunnel structure lining cutting main body of shield construction, to the quality in whole tunnel with play a part key application life.At present, the type of section of jurisdiction mainly contains ductile iron section of jurisdiction, steel pipe sheet, compound section of jurisdiction and reinforced concrete segment, and wherein reinforced concrete lining layer section of jurisdiction is the most frequently used section of jurisdiction form.
Domestic concrete design strength grade is all at C50 or more, and demoulding strength is at more than 18MPa, and most of enterprise is 20MPa.Can see from current actual tests data, 28d intensity and intensity of dispatching from the factory all can reach design strength grade, but demoulding strength is between 13-50MPa, and for the enterprise of demoulding strength at below 15MPa, major part adopts the mode of the vacuum cup demoulding, these enterprises, through production practices for many years, find that demoulding strength is smaller and do not cause damage to product.And for the hanging demoulding that current most of enterprise adopts, concrete strength controls when 20MPa, generally can not cause damage to concrete.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of concrete lining pipe piece test mould, this test mould imitates production mould and makes, it mainly meets the requirement of test, by the concrete workability of this mould test C50, early epistasis energy under stream curing, can reach more than 15MPa during the demoulding, whether the concrete lining pipe piece of preparation there will be ripple glaze etc.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of concrete lining pipe piece test mould, comprise bottom panel, front end-plate, end plate, first member plate, right end plate and upper cover, described front end-plate, end plate, first member plate, right end plate join end to end and surround one with bottom panel and build cavity volume, described front end-plate and the top of end plate are arc-shaped structure, and described upper cover is that arc-shaped structure matches with the top of front end-plate and end plate and is fastened on the top of building cavity volume.
In a preferred embodiment of the present invention, the outer middle side part of described front end-plate and end plate is horizontally arranged with reinforcing rib respectively.
In a preferred embodiment of the present invention, cover and be provided with observation port and handle on described, described observation port is arranged on the centre position of upper cover, and described handle is separately positioned on the left and right sides of upper cover.
In a preferred embodiment of the present invention, described front end-plate and the height of end plate are 150-225mm, and the height of first member plate and right end plate is 150mm.
In a preferred embodiment of the present invention, described concrete lining pipe piece test mould adopts stainless steel material to make.
The invention has the beneficial effects as follows: concrete lining pipe piece test mould of the present invention, this test mould imitates production mould and makes, it mainly meets the requirement of test, by the concrete workability of this mould test C50, early epistasis energy under stream curing, can reach more than 15MPa during the demoulding, whether the concrete lining pipe piece of preparation there will be ripple glaze etc.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the assembling assumption diagram of a preferred embodiment of concrete lining pipe piece test mould of the present invention;
Reference numeral is as follows: 1, bottom panel, and 2, front end-plate, 3, end plate, 4, first member plate, 5, right end plate, 6, upper cover, 7, reinforcing rib, 8, observation port, 9, handle.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the embodiment of the present invention comprises:
A kind of concrete lining pipe piece test mould, comprise bottom panel 1, front end-plate 2, end plate 3, first member plate 4, right end plate 5 and upper cover 6, described front end-plate 2, end plate 3, first member plate 4, right end plate 5 join end to end and surround one with bottom panel 1 and build cavity volume, described front end-plate 2 and the top of end plate 3 are arc-shaped structure, and described upper cover 6 is that arc-shaped structure matches with the top of front end-plate 2 and end plate 3 and is fastened on the top of building cavity volume.
