Abstract
The utility model relates to a pressure grouter at the end of a pre-stress concrete tubular pile, which is characterized in that the pressure grouter comprises a base plate, a top board, a cushion block and a pile tip. The base plate is welded with a grouting pipe at the center; the base plate and the top board are connected through the cushion block; a cavity therein is a pressure cavity for grouting; the top board is connected with the pile tip. High-pressure grout is grouted into the pressure cavity between the base plate and the top board through the grouting pipe in the grouter; by adopting a transversal injecting and penetrating method, the grout first reinforces soil horizon at the pile tip through grouting sinks around the pressure cavity, then backflows upwards along the body of the tubular pile under the action of high pressure and reinforces soil horizon at the side of the pile through penetration. Being arranged at the four sides of the pressure cavity, the grouting sinks have the protection function of a guard plate, and the phenomenon that the grouting pipe is blocked and can not be opened is not going to happen during the peening and pile pressing process, and grouting at the end of the tubular pile is 100 percent guaranteed to be successful.
Description
Technical field
The utility model relates to a kind of prestressed concrete pipe pile pile-end pressure grouting device.
Background technology
Prestressed concrete pipe pile is the domestic in recent years pile foundation engineering that develops application rapidly, because it is the commodity stake of adopting batch production, mechanization, scale, producing in serial form, is one of stake type commonly used of guaranteeing of at present domestic tool reliable quality.At stake end setting pressure slurry casting machine, with cement paste soil layer infiltration filling around the stake end, be used to reinforce bearing course at pile end, improve the bearing capacity of single pile of pile foundation.It is terminal that the Grouting Pipe of present applied slip casing by pressure device extends to the stake point always, stops up Grouting Pipe during slip casting easily, and slip casting is not smooth, influences work quality and efficient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of prestressed concrete pipe pile pile-end pressure grouting device, solves Grouting Pipe and occurs easily stopping up the phenomenon of not opening, and guarantees the success of pile tube pile end grouting 100%.
The utility model prestressed concrete pipe pile pile-end pressure grouting device, it is characterized in that comprising chassis, top board, cushion block and stake point, center chassis welding Grouting Pipe connects by cushion block between chassis and the top board, cavity therebetween is the grouting pressure chamber, and top board connects the stake point.
Described stake point is made up of the sharp floor of stake that is " ten " word shape, is convenient to clash into pile.
During construction, Grouting Pipe should be arranged in the pile tube stake hole in advance, and length must not surpass every joint bump pile tube stake top, use the pipe collar screwed connection during pile extension, when carrying out pile-end pressure grouting behind the pile, use bar dowel at stake top place fixing with the Grouting Pipe welding, the Grouting Pipe swing of trembling when preventing high-pressure slip-casting.The chassis of slurry casting machine is directly welded with stake end end plate and is got final product.Be provided with the slip casting groove around the pressure chamber, this slip casting groove grouting amount is big, and slip casting is even, and the resistance degree of depth little, that be penetrated into stake end soil layer is dark, and slip casting effect is good.
After pile tube enters bearing stratum, this slurry casting machine is injected into the high pressure cement paste in the pressure chamber between chassis and the top board by Grouting Pipe, cement paste is at first reinforced stake end soil layer with the method for horizontal injection infiltration by the slip casting groove around the pressure chamber, stake end soil layer is reinforced, improved the end resistance of stake end soil layer; And then cement paste upwards backflows along pile body under the high pressure effect, the soil layer of the penetration reinforcement stake side by cement paste, improve the collateral resistance of stake side soil layer, thereby the bearing capacity of stake is greatly improved, difference according to soil layer property, generally can improve 40～60%, especially sandy soil be improved better effects if.Because this slip casting groove is located at four sides of pressure chamber, has the backplate protective effect, in knocking piling process, Grouting Pipe can not occur and stop up the phenomenon of not opening, guarantee the success of pile tube pile end grouting 100%.The utility model has been owing to improved the bearing capacity of stake, makes engineering can reduce the quantity of stake or shortens pile body length, or use small bore stake etc. instead, can reduce construction costs.
