Abstract
The utility model relates to a preburied pipe pile grouting device which comprises prestressed concrete pipe piles; at least two symmetrically distributed grouting pipes are preburied in the prestressed concrete pipe piles, grout outlet holes are formed on the grouting pipes, and the grouting pipes extend to the ground and are connected with a grouting pump and a pressure gauge; end boards are arranged at the ends of the pipe piles and connected with the preburied grouting pipes through bolts, and grout stopping sealing gaskets are arranged at the joints of the pipe piles; the ends of the preburied grouting pipes adjacent to a hole bottom are reliably sealed to prevent grout leakage; the two vertically adjacent grouting pipes are correspondingly connected through a hollow bolt and a sealing washer; and the grout outlet holes are movably sealed, so as to avoid being blocked by rock soil. The preburied pipe pile grouting device provided by the utility model has the advantages that after the pipe piles are put in place, grout is poured into the gaps between the external walls of the prestressed concrete pipe piles and the surrounding rock-soil layer, so as to increase the pile body lateral friction resistance and the pipe tip resistance, and achieve a simple and reliable construction method.
Description
Technical field
The utility model relates to the grouting device of prestressed pipe pile foundation, particularly a kind of pre-buried type pile tube grouting device.
Background technology
The drilling follow pile tube is a kind of novel stake; the drilling follow pile tube combines the advantage of hand excavated pile, brill (dashing) hole pouring pile, pile for prestressed pipe; overcome and adopted easily collapse in mud off contaminated environment, the drilling process hole, the unsettled shortcoming of concrete casting quality in the bored pile construction method; and the formula pile for prestressed pipe of squeezing into shortcoming such as easily cause that the soil body has fallen;, speed of application strong to geological conditions compliance is fast, reliable in quality, material consumption are few, the bearing capacity height of stake, mechanized, nothing 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, makes between the geotechnical body of pile tube and hole wall and leaves certain space, mostly present grouting method is the down slip casting from top, fill not full, and difficult monitoring, the carrying dynamics of influence stake.
Behind the same static pressure pipe pile and hammering pile tube pile that generally uses at present, also there are the problems referred to above.
The utility model content
The purpose of this utility model is at the problems referred to above, a kind of pre-buried type pile tube grouting device is provided, this device can be effectively in the space of prestressed concrete pipe pile outer wall and rock-soil layer on every side, stake bottom portion grout injection, reach the effect that improves pile body side friction and end resistance.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of pre-buried type pile tube grouting device, it comprises at least two above Grouting Pipe that are embedded with symmetrical distribution in the prestressed concrete pipe pile, has slurry outlet on the Grouting Pipe, Grouting Pipe extends to ground and joins with grouting pump, pressure meter.
Described pipe pile end portion is provided with end plate, and is connected by bolt with pre-buried Grouting Pipe, and the pipe pile joint place is provided with only starches gasket seal.
Described pre-buried Grouting Pipe is adopting positiver sealing near the termination of position, bottom, hole, in case the leak-stopping slurry.
Described adjacent two joint Grouting Pipe are up and down joined by hollow bolt, seal washer correspondence.
Described slurry outlet is a movable sealing, stops up slurry outlet to prevent ground.
Slurry outlet described in the utility model can be arranged several by construction requirement, and slurry outlet needs movable sealing before construction, stops up slurry outlet to prevent ground.
The utility model compared with prior art, its beneficial effect is:
(1) the utility model is by pre-buried Grouting Pipe, and injects mud by pre-buried Grouting Pipe to positions such as pile bodies, can fill up the prestressed concrete pipe pile outer wall and the space of rock-soil layer on every side effectively, reaches the effect that improves pile body side friction and end resistance.
(2) have more movable injected hole by the required setting of engineering on the Grouting Pipe, when injecting cement paste, internal pressure is got through injected hole, and cement paste flows out from injected hole, and the pouring in down a chimney of other materials when both having prevented construction can guarantee construction quality again.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial structurtes cut-away view of Fig. 1.
Fig. 3 is the partial enlarged drawing of slurry outlet among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises: the prestressed concrete pipe pile 3 of pre-buried four symmetrical distribution Grouting Pipe 1, Grouting Pipe 1 extend to ground and join with grouting pump 2 and pressure meter 7.The end plate place that connects Grouting Pipe 1 and prestressed concrete pipe pile 3 tops is provided with hollow bolt, connects adjacently two to save on the prestressed concrete pipe pile 3 pairing Grouting Pipe 1 of pre-buried Grouting Pipe 1 and be respectively equipped with hollow bolt and seal washer up and down.Grouting Pipe 1 near head position, bottom, hole adopts positiver sealing, in case the leak-stopping slurry.Lay some slurry outlets by construction requirement in advance in the appropriate location of Grouting Pipe 1, closely twine layout pulp nose end with adhesive tape before the slip casting, stop up to prevent ground; During construction, utilize the slurry outlet of grouting pump 2 and pressure meter 7 by Grouting Pipe 1 grout injection in the space of prestressed concrete pipe pile 3 outer walls and rock-soil layer on every side, pressure meter 7 is used to measure cement paste or water pressure.
The utility model is in the specific embodiment of work progress;
(a) laid slurry outlet 6 on the high-pressure slip-casting pipe 1 after, the movable earlier prestressed concrete pipe pile 3 that seals slurry outlet 6 (as closely twine the slurry outlet 6 of laying with adhesive tape), Grouting Pipe 1 near head position, bottom, hole is adopted positiver sealing, carry out the drilling follow tube pile construction then, the high-pressure slip-casting pipe 1 usefulness hollow bolt of adjacent two joint prestressed concrete pipe piles, 3 correspondences is connected with gasket seal (not shown).After prestressed concrete pipe pile 3 arrives the projected depth positions, stop to creep into, then to the elongated concrete perfusion 5 of drilling follow pile tube stake core or near the stake end certain altitude scope concrete perfusion 5.
(b) after concrete 5 to be poured into solidifies three to five days, inject clear water successively to the high-pressure slip-casting pipe of laying 1, get through the slip casting passage 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 the full prestressed concrete pipe pile outer wall and the space of rock-soil layer on every side.
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.
Same static pressure pipe pile that generally uses at present and hammering pile tube pile also can improve the bearing capacity of stake by the utility model.
