Abstract
The present invention relates to a kind of processing method of stone matter tunnel inverted arch scum silica frost, this method is first to excavate inverted arch by drawing and code requirement, and then in inverted arch bottom surface, midline sets one of central ditch, and catch pit is arranged in tunnel excavation bottom center line design altitude lowest point；Scum silica frost is flushed to central ditch, the water in catch pit is then walked with pumping, clears up the sediment in the sum aggregate puddle of central ditch；Then one layer of cement mortar is spread in the inverted arch excavation face cleared up；Finally with spray anchor material or plain concrete filling ditch and catch pit.Advantages of the present invention is embodied in：Ditch directly is set in inverted arch excavation face, has the advantages that easy to operate, control is simple, ensure construction quality, performing that cost is low, prevents stress concentration.
Description
Technical field
The present invention relates to a kind of processing method of inverted arch scum silica frost, and in particular to a kind of processing side of stone matter tunnel inverted arch scum silica frost
Method.
Background technology
Scum silica frost influences bonding and the occlusion of concrete and tunnel inverted arch, directly affects the construction quality and safety in tunnel；One
All it has been manually to clean direct casting concrete after inverted arch with besom since straight, and besom is difficult to neatly remove inverted arch scum silica frost, especially
The small scum silica frost of its particle is stayed in inverted arch, it is likely that is formed interlayer between the scar and concrete of inverted arch, is seriously affected engineering
Quality.
The content of the invention
The purpose of the present invention is for deficiency of the prior art, there is provided a kind of stone matter tunnel inverted arch scum silica frost easy to operate
Processing method, this method do not interfere with the bonding of tunnel inverted arch and institute's casting concrete.
To achieve the above object, the invention discloses following technical solution：
A kind of processing method of stone matter tunnel inverted arch scum silica frost, this method are first to excavate inverted arch by drawing and code requirement, so
In inverted arch bottom surface, midline sets one of central ditch afterwards, and the center ditch is width * depth=15cm*15cm, at tunnel excavation bottom
Catch pit is arranged in face center line design altitude lowest point；Scum silica frost is flushed to central ditch, the water in catch pit is then walked with pumping,
Sediment in the sum aggregate puddle of cleaning central ditch；Then one layer of cement mortar is spread in the inverted arch excavation face cleared up；Finally with spray anchor
Material or plain concrete filling ditch and catch pit.
As a preferred embodiment, when scum silica frost being flushed to central ditch, using giant as the instrument for washing away scum silica frost.
As a preferred embodiment, when clearing up the sediment in the sum aggregate puddle of central ditch, cleared up using artificial concentrate.
As a preferred embodiment, the plain concrete is the plain concrete with inverted arch with label.
As a preferred embodiment, the central ditch is to be excavated along the eminence of tunnel floor design to lower, catch pit
It is arranged on this circulation tunnel inverted arch excavation face design altitude lowest point.
A kind of processing method of stone matter tunnel inverted arch scum silica frost disclosed by the invention, compared with existing construction method, directly exists
Ditch is set in inverted arch excavation face, has that easy to operate, control is simple, ensure construction quality, performs that cost is low, prevents stress collection
The advantages of middle.
Brief description of the drawings
Fig. 1 is a kind of schematic cross-section of the processing method of stone matter tunnel inverted arch scum silica frost of the present invention.
Fig. 2 is a kind of schematic top plan view of the processing method of stone matter tunnel inverted arch scum silica frost of the present invention.
Description of reference numerals：
1. inverted arch, 2. central ditches, 3. catch pits.
Embodiment
With reference to embodiment and referring to the drawings the invention will be further described.
A kind of processing method of stone matter tunnel inverted arch scum silica frost, this method are first to excavate inverted arch 1 by drawing and code requirement, so
One of central ditch 2 is set in 1 bottom surface midline of inverted arch afterwards, central ditch is width * depth=15cm*15cm, in tunnel excavation bottom surface
Catch pit 3 is arranged in center line design altitude lowest point；Scum silica frost is flushed to central ditch 2, is then walked with pumping in catch pit 3
Water, clears up the sediment in central ditch 2 and catch pit 3；Then one layer of cement mortar is spread in 1 excavation face of inverted arch cleared up；Finally
With spray anchor material or plain concrete filling ditch and catch pit 3.Inverted arch filling and side can be finally performed by conventional construction method
The concreting of wall and crown.
Central ditch 2 has easy to operate, the simple feature of control, before performing the setting-out of e measurement technology personnel elder generation go out tunnel
The position of center line, then to the midline both sides respectively stretch out 7.5cm start excavate ditch 2, ditch size is smaller, can use hand air drill
Spade is added manually to be performed；Catch pit 3 can be coordinated with the excavator with drill bit manually to be performed.
Compared with prior art, the present invention sets central ditch 2 directly in 1 excavation face of inverted arch, has easy to operate, control
Simply, ensure construction quality, perform the advantages of cost is low.
As specific embodiment, when scum silica frost is flushed to central ditch 2, using giant as the instrument for washing away scum silica frost,
Inverted arch scum silica frost can be enable more thoroughly to clean out, the pressure of giant will meet the requirements, can be with for larger scum silica frost
Manually directly clear up.
As specific embodiment, when the granule sediment of central the inside of ditch 2 is difficult to clear up, can with giant by its
Catch pit 3 is flushed to, after stand-by water pump exhausts the water in catch pit, construction personnel puts on galosh in the larger catch pit 3 in space
Clear up the sediment compared with small particle；Then one layer of cement mortar is spread in the inverted arch excavation face cleared up；Filled with inverted arch with label
Ditch 2 and catch pit 3 set by Concrete Filled, prevent stress concentration；It is last traditionally perform again it is ensuing other
Process.
As specific embodiment, the plain concrete is the plain concrete with inverted arch with label.
As specific embodiment, the center ditch 2 is to be excavated along the eminence of tunnel floor design to lower, catch pit 3
It is arranged on this circulation tunnel inverted arch excavation face design altitude lowest point.
The above is only the preferred embodiment of the present invention, rather than its limitations；It should be pointed out that although with reference to above-mentioned each
The present invention is described in detail in embodiment, it will be understood by those of ordinary skill in the art that, it still can be to above-mentioned each
Technical solution described in embodiment is modified, or carries out equivalent substitution to which part or all technical characteristic；And this
A little modifications and replacement, do not make the essence of corresponding technical solution depart from the scope of various embodiments of the present invention technical solution.
