Abstract
The invention provides a concrete lining formwork trolley insertion-type concrete grouting construction method. A traditional arch concrete grouting technological method in tunnel template trolley concrete construction is broken through, and cavities are effectively prevented from being formed in the concrete grouting process. The method is a revolutionary tunnel concrete construction method and a new idea and a new concept of template trolley concrete construction, and tunnel concrete damage can be effectively prevented.
Description
Technical field：
The present invention relates to concrete pouring forms construction field of constructing, inserts more particularly, to a kind of concrete lining formwork jumbo
Formula concrete grouting construction method.
Background technology：
It is well known that current lining construction, using formwork jumbo arch wall lining concrete, concrete perfusion be from down to
On, it is left and right symmetrical, in last tunnel top concrete perfusion, using from top form surfacing opening, headed into by pipeline pumping
Mode carry out top concrete perfusion.As template forms a closed space with country rock, it is not easy to observe its internal filling
Whether note is filled, and judges with filling concrete amount, pressure by rule of thumb entirely.In the concrete that dome portions are fed into, to overcome and fill
The note concrete resistance for bringing and the gravity that newly enters concrete itself, and the factor such as inner chamber pressure resistance.It is easy to top shape
Into cavity, tunnel-liner disease is caused.If because being afraid of that cavity occurs in lining cutting, mandatory increase amount of concrete or raising concrete are defeated
Rated pressure is sent, the template of formwork jumbo can be damaged, template deformation is shone into.If reserving secondary grouting mouth in template, to which
The cavity that concrete is left carries out secondary grouting, can increase by one working procedure, increase cost again.Disease is formed easily, is solved
It is difficult, it is therefore necessary to start to prevent from source, be only the best way.
The content of the invention：
It is above-mentioned in order to overcome the shortcomings of, the invention provides a kind of construction of concrete lining formwork jumbo plug-in type filling concrete
Method.
The technical solution adopted for the present invention to solve the technical problems：
A kind of concrete lining formwork jumbo plug-in type concrete grouting construction method, comprises the steps：
A, in tunnel form chassis vault template highest point, along tunnel longitudinal axis direction, be evenly arranged plug-in type per 3 meters of spacing
Filling concrete mouth, pouring forms chassis concrete to it is lower and on, left and right symmetrical, the position below the template of top has irrigated
Cheng Hou, pumping line are connected with test tube；
B, hydraulic jack rise, and advance inner tube, are inserted into and are close at country rock；
C, concrete are pumped up pipe flow and enter side pipe, afterwards into inner tube, finally deliver in the template of top；
After D, the perfusion of template inner concrete are full, hydraulic jack is recovered to inner tube outside template；
The concrete in stop block closing inner tube on E, outer tube, placement prevent template inner concrete from coming off and forming cavity；
F, closing sealing plate, close the perfusing hole in template；
G, dismantling concrete delivery pump pipe, rinse inner tube, outer tube and side pipe.
There is following superiority due to adopting technical scheme as above, the present invention：
A kind of concrete lining formwork jumbo plug-in type concrete grouting construction method of the present invention, has broken tunnel form
Dome portions filling concrete process traditional in chassis concrete construction, forms empty during effectively preventing filling concrete
Hole, is a kind of reform property tunnel concrete construction method, is a kind of new approaches, the new concept of formwork jumbo concrete construction, energy
It is enough effectively to prevent tunnel concrete disease.
Description of the drawings：
Fig. 1 is the filling concrete schematic diagram of the present invention；
Fig. 2 is the closing schematic diagram of concrete of the present invention；
In figure：1st, inner tube；2nd, outer tube；3rd, stop block；4th, hydraulic jack；5th, side pipe；6th, closed plate；
Specific embodiment：
The present invention can be explained in more detail by example below, the open purpose of the present invention is intended to protect in the scope of the invention
All changes and improvements, the invention is not limited in the following examples；
Perfusing hole is provided with closed plate 6, the template perfusing hole after casting complete on Sealing formboard, and intrusion pipe is by inner tube 1, outer tube 2
Constitute with side pipe 5, inner and outer pipe mutually can slide, and gap very little, 1 bottom of inner tube is connected with hydraulic jack 4, and hydraulic jack 4 can
With drive inner tube 1 move up and down, outer tube 2 is integral with 5 cross weld of side pipe, and is mutually communicated, 1 bottom lateral opening of inner tube and
Outer tube 2, side pipe 5 are open, and concrete energy smoothness passes through, and 2 bottom of outer tube is provided with stop block 3, and stop block 3 includes being welded on
The cross bar of outer pipe bottom and ride on cross bar and the baffle plate in inner tube 1, the side of inner tube 1 is provided with fluting, convenient interior
During moving up and down, stop block 3 can be maintained static pipe 1, prevent coming off for concrete.
Specific work process is as follows：
A kind of concrete lining formwork jumbo plug-in type concrete grouting construction method, comprises the steps：
A, in tunnel form chassis vault template highest point, along tunnel longitudinal axis direction, be evenly arranged plug-in type per 3 meters of spacing
Filling concrete mouth, pouring forms chassis concrete to it is lower and on, left and right symmetrical, the position below the template of top has irrigated
Cheng Hou, pumping line are connected with test tube；
B, hydraulic jack rise, and advance inner tube, are inserted into and are close at country rock；
C, concrete are pumped up pipe flow and enter side pipe, afterwards into inner tube, finally deliver in the template of top；
After D, the perfusion of template inner concrete are full, hydraulic jack is recovered to inner tube outside template；
The concrete in stop block closing inner tube on E, outer tube, placement prevent template inner concrete from coming off and forming cavity；
F, closing sealing plate, close the perfusing hole in template；
G, dismantling concrete delivery pump pipe, rinse inner tube, outer tube and side pipe.
Part is not carefully stated in above content for prior art, therefore is not run business into particular one and stated.
