Description
Technical field:
The utility model relates to a kind of concrete construction facility, is specially a kind of metamorphosis concrete slurry adding device.
Background technology:
In concrete construction, abnormal concrete be paved treat to mix cement paste in roller compacted concrete and impose vibrate, to reach the concrete of the performance indications such as similar normal concrete compactness and intensity.It can solve large volume Hydro-concrete Structures construction between normal concrete and roller compacted concrete because of in conjunction with problems such as many materials such as bad or deformation, Structure and energy, be widely used in concrete dam and build.The core link of abnormal concrete construction technique adds slurry and vibrate to control.For convenience of construction, add slurry mode at present still manually to add slurry: directly spread out and put on by slurries on roller compacted concrete surface, treat cement grout infiltration downwards naturally.This adds, and paste-making method work efficiency is lower, construction is random large, slurries can be caused to spread out and put on skewness in material at roller compacted concrete, have a strong impact on the even density that abnormal concrete is shaping.The patent No. 2014205337623 discloses a kind of portable abnormal concrete intelligent high-pressure filling system, this system has following three place's defects to need to make up: 1, there is a telescoping catheter at this system slip casting rod place, the effect of telescoping catheter is when system does not work, cement grout splash everywhere in restriction slip casting rod, but in the course of the work, workman often can not stablize and plugs telescopic tube vertically, making in the course of work telescopic tube can not normally opening and closing, causing cement grout easy splash everywhere when not having telescopic tube to limit; 2, often there is silting problem in this system grout pipe line in mortar depositing construction process; 3, in this system, terrace with edge table top is vertical at an angle of 90 with slip casting rod surface, and high pressure slurries reflect rear to not controlling from penetrating in rubber grommet through upper terrace with edge, cause slurries to flash.
Summary of the invention:
Problem to be solved in the utility model is exactly provide one effectively can control slurries injection direction for above deficiency, reduces slurry pipe line silting, can facilitate the metamorphosis concrete slurry adding work rod of mortar depositing construction.Its technical scheme is as follows:
It comprises electric hammer, feed pipe for mortar, slip casting rod and casting head, and slip casting rod is connected with feed pipe for mortar, electric hammer and casting head, and casting head is provided with slurry outlet.Its key technology is provided with terrace with edge on slip casting rod, and slurry outlet is between two terrace with edges, and terrace with edge has upper table surface and following table, the following table on the upside of slurry outlet is provided with gear angle being positioned at, and is being positioned at circular arc that the upper table surface on the downside of slurry outlet polishes.
The angle at described gear angle is 40 ~ 50 degree.
Described slurry outlet overcoat has rubber neck, and rubber neck is fixed between two terrace with edges.
Described casting head is threaded connection on slip casting rod.
Described slurry outlet is designed to structure wide outside and narrow inside.
Compared with prior art, the beneficial effect that the utility model has is:
1, on slip casting rod, terrace with edge is provided with, following table on the upside of slurry outlet is provided with gear angle being positioned at, when slurries spray on the upside of rubber grommet, making the final injection direction of slurries downward by keeping off the reflex at angle, being positioned at circular arc that the upper table surface on the downside of slurry outlet polishes, when slurries spray, slurries flow away downwards along circular arc, and same guarantee slurries injection direction is downward, by the polishing to the upper and lower table top of terrace with edge, effective control slurries injection direction, offers convenience to abnormal concrete construction.
2, casting head is threaded connection on slip casting rod, and adopting is threaded is convenient to the dismounting of casting head, can discharge the cement grout accumulated in grout pipe line in time, solve the problem of cement grout silting after unloading casting head.
3, slurry outlet is designed to structure wide outside and narrow inside, the plugging phenomenon that this structure can effectively stop large-particle-size aggregate in concrete to enter feed pipe for mortar to cause.
4, above advantage, still can effectively control slurries injection direction after making metamorphosis concrete slurry adding work rod eliminate original telescopic tube, greatly improves the convenience of slip casting rod work, facilitates abnormal concrete construction.

Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
See Fig. 1 ~ Fig. 3, the utility model comprises electric hammer 1, feed pipe for mortar 2, slip casting rod 3 and casting head 5, and slip casting rod 3 is connected with feed pipe for mortar 2, electric hammer 1 and casting head 5, and casting head 5 is provided with slurry outlet 4.Its key technology is provided with terrace with edge 10 on slip casting rod 3, slurry outlet 4 is between two terrace with edges 10, terrace with edge 10 has upper table surface and following table, following table on the upside of slurry outlet 4 is provided with gear angle 7 being positioned at, when slurries spray on the upside of rubber grommet, make the final injection direction of slurries downward by the reflex of keeping off angle 7; Be positioned at circular arc 8 that the upper table surface on the downside of slurry outlet 4 polishes, when slurries spray, slurries flow away downwards along circular arc 8, same guarantee slurries injection direction is downward, by the polishing to the upper and lower table top of terrace with edge, effective control slurries injection direction, thus telescopic tube in original system can be saved, offer convenience to abnormal concrete construction.
The angle at described gear angle 7 is 40 ~ 50 degree.
Described slurry outlet 4 overcoat has rubber neck 9, and rubber neck 9 is fixed between two terrace with edges 10.
Described casting head 5 is connected on slip casting rod 3 by screw thread 6, and adopting is threaded is convenient to the dismounting of casting head, can discharge the cement grout accumulated in grout pipe line after unloading casting head 5 in time, reduces slurries silting.
Described slurry outlet 4 is designed to structure wide outside and narrow inside, the plugging phenomenon that this form can effectively stop large-particle-size aggregate in concrete to enter feed pipe for mortar 2 to cause.
When workman carries out slip casting operation, hand held electric hammer 1, utilize the brisance that hits of electric hammer 1 to spread out and put in roller compacted concrete by slip casting rod 3 insertion, cement grout is sent in slip casting rod 3 by feed pipe for mortar 2 by rear end equipment.Casting head 5 is connected by screw thread 6 with slip casting rod 3, when filling system stops slip casting temporarily, unloads casting head 5 and can discharge the cement grout accumulated in grout pipe line in time, prevent slurries silting.
