Abstract
The utility model discloses a kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces, belong to technical field of civil engineering.A kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present utility model, comprise castinplace pile, described castinplace pile is formed in construction ground, described castinplace pile outer cover is provided with sleeve pipe, and the length of this sleeve pipe is the distance of design of pile top absolute altitude to nature terrace absolute altitude; The accommodation space for filling water or thin mud is there is between described sleeve pipe and castinplace pile.The utility model structure is simple, Be very effective, avoids the above pile cutoff of castinplace pile king-pile top design elevation and produces frictional force, ensure that accuracy during castinplace pile detection bearing capacity.
Description
Technical field
The utility model relates to technical field of civil engineering, more particularly, relates to a kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces.
Background technology
The detecting of bearing capacity of a pile designing test pile in common engineering all detects at natural terrace, and natural terrace generally all exceeds engineering pile design of pile top absolute altitude, distance between this natural terrace and engineering pile design of pile top absolute altitude account for total stake long 1/3, if do not take measures, this section of frictional force accounts for the total bearing capacity large percentage of stake, and the frictional force extending the long generation of this section of stake of nature terrace cannot detect, the theoretical value deduction provided by exploration report, to determining that engineering pile bearing capacity of single pile creates very large error.
Summary of the invention
1. the utility model technical problem that will solve
The purpose of this utility model is to overcome above-mentioned problem, provide a kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces, adopt the technical solution of the utility model, structure is simple, eliminate the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces, ensure that accuracy during castinplace pile detection bearing capacity.
2. technical scheme
For achieving the above object, the technical scheme that the utility model provides is:
A kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present utility model, comprise castinplace pile, described castinplace pile is formed in construction ground, described castinplace pile outer cover is provided with sleeve pipe, and the length of this sleeve pipe is the distance of design of pile top absolute altitude to nature terrace absolute altitude; The accommodation space for filling water or thin mud is there is between described sleeve pipe and castinplace pile.
Further, the soil being positioned at described sleeve pipe surrounding is mud, and this mud is formed according to native water proportioning 1:2 stirring by jet grouting pile driving machine.
3. beneficial effect
The technical scheme adopting the utility model to provide, compared with existing known technology, has following beneficial effect:
(1) a kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present utility model, its castinplace pile outer cover is provided with sleeve pipe, the length of this sleeve pipe is the distance of design of pile top absolute altitude to nature terrace absolute altitude, the accommodation space for filling water or thin mud is there is between sleeve pipe and castinplace pile, avoid the above pile cutoff of castinplace pile king-pile top design elevation and produce frictional force, ensure that accuracy during castinplace pile detection bearing capacity;
(2) a kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present utility model, its structure is simple, Be very effective.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation eliminating the structure of the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present utility model.
Label declaration in schematic diagram: 1, castinplace pile; 2, sleeve pipe.
Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment
Composition graphs 1, a kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present embodiment, comprise castinplace pile 1, castinplace pile 1 is formed in construction ground, castinplace pile 1 outer cover is provided with sleeve pipe 2, and the length of this sleeve pipe 2 is the distance of design of pile top absolute altitude to nature terrace absolute altitude; The accommodation space for filling water is there is between sleeve pipe 2 and castinplace pile 1; The soil being positioned at described sleeve pipe 2 surrounding is mud, and this mud is formed according to native water proportioning 1:2 stirring by jet grouting pile driving machine.
Mounting method: (1) castinplace pile 1 is formed and after guaranteeing that concrete piles reaches design strength in construction ground, adopt jet grouting pile driving machine, according to native water proportioning 1:2, the soil of castinplace pile 1 surrounding is stirred to mud, in the present embodiment, mixing position is provided with 5, and this jet grouting pile driving machine stirring degree of depth is the distance from natural terrace absolute altitude to design of pile top absolute altitude; (2) adopt vibratory drilling method to be set in outside castinplace pile 1 by sleeve pipe 2, and the length of this sleeve pipe 2 sinkage and sleeve pipe 2 is the distance of nature terrace absolute altitude to design of pile top absolute altitude; (3) mud be present in the accommodation space between sleeve pipe 2 and castinplace pile 1 uses high pressure water washing while adopting slush pump to extract out, until be all replaced as water or thin mud in accommodation space.The accuracy of supporting capacity now detecting castinplace pile 1 is high, and to be detected after sleeve pipe 2 can extract.
A kind of structure eliminating the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces of the present utility model, structure is simple, Be very effective, avoids the above pile cutoff of castinplace pile 1 king-pile top design elevation and produces frictional force, ensure that accuracy when castinplace pile 1 detects bearing capacity.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
Claims (1)
1. eliminate the structure of the frictional force that design elevation above pile cutoff in castinplace pile king-pile top produces for one kind, comprise castinplace pile (1), described castinplace pile (1) is formed in construction ground, it is characterized in that: described castinplace pile (1) outer cover is provided with sleeve pipe (2), the length of this sleeve pipe (2) is the distance of design of pile top absolute altitude to nature terrace absolute altitude; The accommodation space for filling water or thin mud is there is between described sleeve pipe (2) and castinplace pile (1).
