Abstract
The utility model discloses a tube-side injection grouting apparatus for simultaneous drilling pipe pile comprising a prestressed concrete pipe pile so disposed that the sidewall of the outer wall of the pipe pile is fixedly provided with at least one or more than ore symmetrically-disposed high pressure grouting pipe, one end of the grouting pipe and a high pressure injection pump and a pressure gauge being connected, the other end of the grouting pipe being provided with grouting holes, the grouting holes end being movably closed, the grouting pipe being fixed to the side wall of the outer wall of the pipe pile by an annular coupler or iron wire, the grouting hole of the grouting pipe being disposed in the lower part of the pipe pile, the grouting pipe being provided with plural grouting holes. The grouting holes can be respectively disposed in the upper, middle, and lower part of the pipe pile as required by the project. Before construction, a rubber belt is tightly wound so as to lay out grouting pipe in grouting hole section, and the high pressure grouting injection pump injects high pressure water or cement slurry to pile side through the high pressure grouting pipe, and the pressure gauge is used for measuring pressure of water or cement slurry. After three or fives days after concrete is injected to the pile core of the simultaneous drilling pipe pile or within a certain range of height close to the bottom of the pile, the grouting channel is opened, and one-time high pressure grouting or twice high pressure grouting is to be chosen according to stratum condition. The utility model injects cement slurry to the gap between the outer wall of the prestressed concrete pipe pile and the circumferential rock and oil layer, which can in crease friction resistance of side pile body and resistance at pile end, combined with simple and reliable construction method.
Description
Technical field
The present invention relates to build or the stake side grouting device of bridge pile foundation plinth particularly a kind of stake side grouting device of drilling follow pile tube.
Background technology
The drilling follow pile tube (CN200710029023) that a kind of building or bridge foundation are used is a kind of novel stake; the drilling follow pile tube combines hand excavated pile; bore (dashing) hole pouring pile; the advantage of pile for prestressed pipe; overcome and adopted the mud off contaminated environment in the bored pile construction method; the hole of easily collapsing in the drilling process; the unsettled shortcoming of concrete casting quality; and the formula pile for prestressed pipe of squeezing into shortcoming such as easily cause that the soil body has fallen; strong to geological conditions compliance; speed of application is fast; reliable in quality; material consumption is few; the bearing capacity height of stake; mechanized; there is not construction mud emission problem, the protection environment.But during the drilling follow tube pile construction, drilling diameter is greater than the diameter of prestressed concrete pipe pile, and prestressed concrete pipe pile and have certain space on every side between the geotechnical body has influenced the performance of the pile side friction and the stake bottom resistance of pile tube.
The utility model content
The purpose of this utility model is at the problems referred to above weak point, a kind of stake side grouting device of drilling follow pile tube is provided, this device can be effectively in the space of prestressed concrete pipe pile outer wall and rock-soil layer on every side grout injection, reach the effect that improves pile body side friction and stake bottom resistance.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of stake side grouting device of drilling follow pile tube, comprise prestressed concrete pipe pile, the fixing at least one or more high-pressure slip-casting pipe that is symmetrically distributed on the external diameter sidewall of pile tube, Grouting Pipe one end is connected with high-pressure injection pump, pressure meter, the other end is provided with slurry outlet, and the movable sealing of pulp nose end.
The above Grouting Pipe is fixed on the pile tube external diameter sidewall by loop fasteners or iron wire.
The slurry outlet of the above Grouting Pipe is positioned at the pile tube bottom.
Grouting Pipe slurry outlet described in the utility model can be provided with slurry outlet respectively in the upper, middle and lower of pile tube portion by engineering is required.
The utility model the elongated concrete perfusion of drilling follow pile tube stake core or near the stake end certain altitude scope concrete perfusion.By high-pressure injection pump by the high-pressure slip-casting pipe to prestressed concrete pipe pile and injection water mud or clear water in the space between the geotechnical body on every side.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure sectional view of prestressed concrete pipe pile and high-pressure slip-casting pipe among Fig. 1.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
As shown in Figure 1 and Figure 2, four high-pressure slip-casting pipes 1 described in the utility model are symmetrically distributed on the prestressed concrete pipe pile 3 external diameter sidewalls, Grouting Pipe 1 and pile tube 3 both be fixedly connected on the sidewall of pile tube 3 Grouting Pipe 1 by loop fasteners (as stirrup) or iron wire 6, Grouting Pipe 1 is provided with some slurry outlets, the slurry outlet port needs movable sealing before construction, Grouting Pipe 1 end that bassets is connected with high-pressure injection pump 2, and high-pressure injection pump also is connected with pressure meter 7, is used to measure cement paste or water pressure.
The utility model is in the specific embodiment of work progress;
1) laid slurry outlet on the high-pressure slip-casting pipe 1 after, earlier closely twine slurry outlet with adhesive tape, make slurry outlet be in closed state, prevent that sandy soil from pouring in down a chimney; High-pressure slip-casting pipe 1 is fixed on the external diameter sidewall of prestressed concrete pipe pile 3 with annular stirrup or iron wire 6, carries out the drilling follow tube pile construction then; After prestressed concrete pipe pile 3 arrives the projected depth positions, stop to creep into, at this moment certain space 4 is arranged between pile tube 3 and the drilling diameter, to the elongated concrete perfusion 5 of drilling follow pile tube stake core or near the stake end certain altitude scope concrete perfusion 5.
2) after concrete 5 to be poured into solidifies 3 to 5 days, inject clear water successively to the high-pressure slip-casting pipe of laying 1, get through slip casting passage and grout outlet by high-pressure injection pump 2.And then to high-pressure slip-casting pipe 1 injection water mud successively.In slip casting (water) process, observe slip casting (water) pressure by pressure meter 7 according to designing requirement; Guarantee that the cement paste injected fills full prestressed concrete pipe pile outer wall and the drilling diameter space 4 of rock-soil layer on every side.
3) for guaranteeing slip casting effect, behind the certain hour of the interval of slip casting first, carry out secondary grouting, improve pile side friction and end resistance.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
