Description

A kind of pile tube

Technical field

This utility model relates to building field, more specifically, it relates to a kind of pile tube when laying the foundations.

Background technology

Cast-in-situ bored pile is the conventional pile-type of one that building foundation construction processes, and owing to it has the advantage such as easy construction, reasonable, the soil property strong adaptability of cost, is used widely in industry and all kinds of foundation construction such as civil buildings, bridge.

If publication number is a kind of mode that CN204125938U name is called disclosed in " superelevation a kind of pile tube by force filled by waste residue ", have employed the mode of waste residue filling to improve the frictional force of a kind of pile tube and soil property part, improve the bearing capacity of prefabricated pile, but what its pile top adopted is taper, rotten stake and the big phenomenon of deflected file easily occur when piling.

Utility model content

The purpose of this utility model is to provide the pile tube that a kind of bearing capacity is strong and rock breaking capacity is strong.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of pile tube, pile body including hollow, the bottom end face of described pile body is connected to end plate, at least one Grouting Pipe it is provided with in described pile body, the lower end of this Grouting Pipe is through end plate and fixes with end plate, the peviform frost boiling dish being arranged below being connected to bottom pile body in Grouting Pipe, the basin edge of peviform frost boiling dish is that spacing coordinates with pile body lower end, the opposite side of the described peviform relative pile body of frost boiling dish is provided with pile top, described pile top includes being connected to the ring flat-plate that frost boiling tray bottom and diameter are bigger than frost boiling tray bottom diameter, described ring flat-plate is wholely set, relative to the opposite side of frost boiling dish, the broken rock annulated column that external diameter is less than ring flat-plate, described broken rock annulated column is away from the end indentation of ring flat-plate.

Pass through such scheme, by injecting high pressure concrete slurry in Grouting Pipe, can discharge from the bottom of Grouting Pipe and fall to peviform frost boiling dish then again from the basin edge of peviform frost boiling dish and spilling the gap of pile body lower end, the bottom of pile body is encased, form the expansion head that outline is bigger than pile body, and then increase the attachment force between soil layer；By the broken rock annulated column in pile top, owing to broken rock annulated column is away from the end indentation of ring flat-plate such that it is able to improve the muck ability of pile tube, not easy glide, and by the setting of ring flat-plate, after slurry overflows from frost boiling dish, better reversely toward pile body flowing, pile body can be encased formation and expands head.

It is optimized for further: break and between rock annulated column and ring flat-plate, be provided with some reinforcements.

By such scheme, the reinforcement of setting, rock annulated column rigidity between ring flat-plate can be increased brokenly further.

It is optimized for further: vertical the first reinforcing bar being provided with annular permutation in pile body, vertical on the first reinforcing bar of annular permutation is arranged at intervals with the second reinforcing bar that multi-turn is fixing with the first reinforcing bar.

By such scheme, by arranging the first vertical reinforcing bar and multi-turn in pile body in spaced second reinforcing bar of vertical direction, so that the structural strength of pile body is greatly enhanced.

It is optimized for further: the outer rim of described pile body is bigger along outer rim than the basin of peviform frost boiling dish.

Pass through such scheme, after piling, owing to the outer rim of pile body is bigger than the outer rim on basin edge, it is possible to make pile body and soil layer fit tightly compression, such that it is able to prevent pile body and space occurs between the hole that the pile top by peviform frost boiling dish is up to, and then occur that pile body is unstable.

It is optimized for further: between described peviform frost boiling dish and the bottom of pile body, adopt steel column to be connected.

Pass through such scheme, can so that the connection between peviform frost boiling dish and pile body becomes more firm by steel column, and after high pressure concrete slurry is drained into peviform frost boiling dish from Grouting Pipe, it is possible to overflow from peviform frost boiling dish smoothly thus forming the expansion head of the bottom wrapping in pile body.

It is optimized for further: the outer wall of described pile body is provided with the recessed groove extended along its length.

By such scheme, when when piling, the soil property being extruded is owing in bottom squeeze, can pass through recessed groove, it is possible to by recessed groove, unnecessary soil property is reversed discharge, so that piling becomes more smooth and easy.

It is optimized for further: the outer wall of described pile body is additionally provided with the annular protrusion along pile body length direction permutation.

It is optimized for further: the side ring limit bottom the relative pile body of described annular protrusion is provided with the chamfering down to pile body.

By such scheme, pass through annular protrusion, it is possible to increase the frictional force between pile body and soil layer, thus improving the ground connection firmness of a kind of pile tube；And the side ring limit bottom relative for annular protrusion pile body is provided with the chamfering down to pile body, thus can be more smooth and easy when piling.

In sum, this utility model has the advantages that by being provided with the first reinforcing bar and the second reinforcing bar in pile body, so that the intensity of pile body is greatly enhanced；Again through Grouting Pipe and peviform frost boiling dish, Grouting Pipe is injected high pressure concrete slurry, can discharge from the bottom of Grouting Pipe and fall to peviform frost boiling dish then again from the basin edge of peviform frost boiling dish and spilling the gap of pile body lower end, the bottom of pile body is encased, form the expansion head that outline is bigger than pile body, and then increase the attachment force between soil layer, it is finally reached a kind of pile tube that pile strength is high and bearing capacity is strong；And by pile top, by being arranged on the sawtooth on the broken rock annulated column of pile top, by increasing capacitance it is possible to increase its rock breaking capacity, not easy glide, and by the setting of ring flat-plate, after slurry overflows from frost boiling dish, it is possible to better reversely toward pile body flowing, pile body is encased formation and expands head.
