Abstract

The invention relates to a disposing method for dross of a stone tunnel invert. The method comprises the steps that firstly, the invert is excavated according to drawing and standard requirements; then a central ditch is formed in the position of the center line of the bottom surface of the invert; a sump is formed in the lowest position of the design elevation of the center line of the excavated bottom surface of a tunnel; the dross is flushed into the central ditch; then water in the sump is pumped through a pump; sediments in the central ditch and the sump are removed; then a layer of cement paste is sprayed to the excavated surface of the clean invert; and finally the ditch and the sump are filled with spray anchor materials or plain concrete. The disposing method has the advantages that the ditch is directly formed in the excavated surface of the invert, operation is convenient, controlling is easy, the project quality is guaranteed, the construction cost is low, and stress concentration is prevented.

Description

A kind of processing method of stone matter tunnel inverted arch scum silica frost
Technical field
The present invention relates to the processing method of a kind of inverted arch scum silica frost, be specifically related to a kind of stone matter tunnel and face upward The processing method of arch scum silica frost.
Background technology
Scum silica frost affects concrete and the bonding of tunnel inverted arch and occlusion, directly affects the engineering in tunnel Quality and safety;It is the most all direct casting concrete after artificial besom cleans inverted arch, And besom is difficult to remove inverted arch scum silica frost neatly, the scum silica frost that especially granule is little is stayed in inverted arch, very Interlayer may be formed between the scar of inverted arch and concrete, have a strong impact on construction quality.
Summary of the invention
It is an object of the invention to for deficiency of the prior art, it is provided that a kind of stone simple to operate The processing method of matter tunnel inverted arch scum silica frost, the method does not interferes with tunnel inverted arch and poured coagulation The bonding of soil.
For achieving the above object, the invention discloses following technical scheme:
The processing method of a kind of stone matter tunnel inverted arch scum silica frost, the method is first to want by drawing and specification Seek excavation inverted arch, then set one central authorities ditch in inverted arch bottom surface midline, at the bottom of tunnel excavation Face centrage design altitude lowest part arranges catch pit;Scum silica frost is flushed to central authorities ditch, then uses Pumping walks the water in catch pit, the sediment in cleaning central authorities ditch and catch pit;Then in cleaning Good inverted arch excavation face spreads one layer of cement mortar;Finally with spray anchor material or plain concrete fill ditch and Catch pit.
As a kind of preferred version, when scum silica frost is flushed to central authorities ditch, use giant conduct Wash away the instrument of scum silica frost.
As a kind of preferred version, when clearing up the sediment in central authorities ditch and catch pit, use people Work concentrates cleaning.
As a kind of preferred version, described plain concrete is with the plain concrete of label with inverted arch.
As a kind of preferred version, described central authorities ditch be wide * deeply=15cm*15cm.
As a kind of preferred version, described central authorities ditch is to low along the eminence of tunnel floor design Place's excavation, catch pit is arranged on this circulation tunnel inverted arch excavation face design altitude lowest part.
The processing method of a kind of stone matter tunnel disclosed by the invention inverted arch scum silica frost, with existing construction party Method is compared, and directly arranges ditch in inverted arch excavation face, have easy to operate, control simple, Ensure construction quality, perform low cost, the advantage preventing stress from concentrating.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of the processing method of the present invention a kind of stone matter tunnel inverted arch scum silica frost.
Fig. 2 is the schematic top plan view of the processing method of the present invention a kind of stone matter tunnel inverted arch scum silica frost.
Description of reference numerals:
1. inverted arch, 2. central authorities ditch, 3. catch pit.
Detailed description of the invention
Below in conjunction with embodiment and referring to the drawings the invention will be further described.
Refer to Fig. 1-Fig. 2.
The processing method of a kind of stone matter tunnel inverted arch scum silica frost, the method is first to want by drawing and specification Seek excavation inverted arch 1, then set one central authorities ditch 2 in inverted arch 1 bottom surface midline, in tunnel Excavation bottom center line design altitude lowest part arranges catch pit 3;Scum silica frost is flushed to central authorities ditch 2, then walk the water in catch pit 3, in cleaning central authorities ditch 2 and catch pit 3 by pumping Sediment;Then one layer of cement mortar is spread in inverted arch 1 excavation face cleared up;Finally with spray anchor material or Plain concrete fills ditch and catch pit 3.Finally just can perform inverted arch by conventional construction method Fill and the concreting of abutment wall with crown.
Central authorities ditch 2 have easy to operate, control simple feature, performing pre-test technology The setting-out of personnel elder generation goes out the position of tunnel center line, and both sides are respectively stretched out 7.5cm and started out the most to the midline Digging ditch 2, ditch size is less, hands air drill can be used to add spade and manually perform;Collection Puddle 3 manually can perform with the excavator cooperation of band drill bit.
Compared to existing technology, the present invention directly arranges central authorities ditch 2 in inverted arch 1 excavation face, Have easy to operate, control simple, ensure construction quality, the advantage performing low cost.
As specific embodiment, when scum silica frost is flushed to central authorities ditch 2, use giant conduct Wash away the instrument of scum silica frost, inverted arch scum silica frost can be enable more thoroughly to clean out, giant Pressure to meet the requirements, and can the most directly clear up for bigger scum silica frost.
As specific embodiment, when the granule sediment inside central authorities ditch 2 is difficult to clear up, can To be flushed to catch pit 3 with giant, after stand-by water pump exhausts the water in catch pit, execute Workman person puts on galosh and clears up the sediment of relatively small particle in the catch pit 3 that space is bigger;Then One layer of cement mortar is spread in the inverted arch excavation face cleared up;The concrete with label is filled with inverted arch Ditch 2 set by filling and catch pit 3, prevent stress from concentrating;Finally the most traditionally execute Do other operations ensuing.
As specific embodiment, described plain concrete is with the plain concrete of label with inverted arch.
As specific embodiment, described central authorities ditch 2 be wide * deeply=15cm*15cm.
As specific embodiment, described central authorities ditch 2 is to low along the eminence of tunnel floor design Place's excavation, catch pit 3 is arranged on this circulation tunnel inverted arch excavation face design altitude lowest part.
The above is only the preferred embodiment of the present invention, is not intended to limit;It should be pointed out that, Although the present invention being described in detail with reference to the various embodiments described above, the ordinary skill of this area Personnel should be appreciated that the technical scheme described in the various embodiments described above still can be repaiied by it Change, or the most some or all of technical characteristic is carried out equivalent;And these are revised and replace Change, do not make the essence of corresponding technical scheme depart from the model of various embodiments of the present invention technical scheme Enclose.
