Castinplace pile avulsion structure
Technical field
The utility model relates to a kind of communal facility building structure, especially relates to a kind of castinplace pile avulsion structure.
Background technology
Manually digging hole method, as a kind of important pouring pile hole technique, has that applicability is comparatively strong, quality is easy to control, low cost, feature that is simple, that do not pollute environment, is widely used in pile foundation engineering.Along with the fast development of urban construction, can develop constantly reducing of location, the bad grounds such as backfill, leveling get more and more as the engineering of building lot, and the scope of backfill, leveling and the degree of depth are also in continuous increase.For being backfilled the ground formed by bulk ragstone, traditional manually digging hole method is more difficult." avulsion " and " quiet split " special engineering method of combined type, improves driving speed significantly and reduces cost; " avulsion " method both can be used alone, and also can use in conjunction with " quiet split " method." avulsion " method special tool is simple, material consumption is low, rubble speed is fast, easy to operate.When this method is used alone, be applicable to the situation that hole sole piece stone occurs probe and has free face.Be abound with boulder at the bottom of hole, then combine " quiet split " method integrated treatment without during free face: one is directly to adopt " quiet split " method, two is first use " quiet split " method to adopt " avulsion " method again after createing and facing the sky scope of freedom.
Summary of the invention
The utility model is mainly for the technical problem that the high material consumption existing for prior art, rubble speed are slow etc., and provide a kind of structure simple, construction cost is lower, and material consumption is little, rubble fireballing castinplace pile avulsion structure.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: castinplace pile avulsion structure goes out borehole by punching pin hammering in stone, punching pin head is tapered, punching pin head both sides are filled with wedge, wedge cross section triangle at a right angle, the angle of one of them acute angle of wedge is equal with the tapering of punching pin head, wedge is outside equipped with ripping bar, ripping bar becomes cylindric, the afterbody of ripping bar is with a flat patty portion, fit bottom cake portion and wedge, an obtuse angle is bent between ripping bar and cake portion, obtuse angle angle is between 150 degree and 170 degree, the middle part of ripping bar and wedge is installed with a movable slide bar.When hammering punching pin, wedge is pressed in block stone, and ripping bar the latter half is also along with wedge is pressed in block stone simultaneously, is outwards pulled by ripping bar along movable slide bar, and the cake portion of bottom holds up wedge and moves up, and punching pin is taken out of borehole simultaneously.
Therefore, it is simple that the utility model has structure, the features such as construction cost is lower, and material consumption is little, rubble speed is fast.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: castinplace pile avulsion structure goes out borehole by punching pin hammering in stone, punching pin 1 head is tapered, punching pin 1 head both sides are filled with wedge 2, wedge 2 cross section triangle at a right angle, the angle of one of them acute angle of wedge 2 is equal with the tapering of punching pin 1 head, wedge 2 is outside equipped with ripping bar 3, ripping bar 3 one-tenth is cylindric, the afterbody of ripping bar 3 is with a flat patty portion 4, fit bottom cake portion 4 and wedge 2, an obtuse angle is bent between ripping bar 3 and cake portion 4, obtuse angle angle is between 150 degree and 170 degree, ripping bar 3 is installed with a movable slide bar 5 (as shown in Figure 1) with the middle part of wedge 2.
