Abstract
The utility model provides a pre -buried coupling of static blasting, includes the powder charge cavity, it is box -like that the main part of powder charge cavity is the confined circle, and the top center and the top of circle box are connected the tube head and are fed through, the radial interval of hoop intercommunication has the side to connect the tube head on the lateral wall of circle box, the top is connected the tube head and is the nozzle stub with side connection tube head. The utility model discloses make packing into of static blasting medicament more convenient, static blasting medicament distribution position is more even, noise and dust pollution when static state is abolished effectual, reducible bored concrete pile pile head and is abolished, and can according to the pre -buried pipe of static blasting of the suitable length of demand intercepting, save pre -buried tube material, pre -buried pipe the connection more convenient.
Description
Technical field
This utility model relates to filling pile construction field, particularly relates to a kind of built-in pipe joint.
Background technology
Owing to using cast-in-place concrete pile in engineering in a large number, for ensureing pile quality, such stake is according to design and construction requirement, when concrete is poured into a mould about designed elevation 0.5m to be exceeded, after pile concrete reaches some strength, the pile crown exceeding designed elevation to be abolished, be commonly called as broken pile head.Conventional method, often uses pneumatic pick or the method such as bombards and abolish this part pile crown, and its construction noise is big, dust is many, and perturbing of producing of mechanical vibration is easily destroyed pile body integrity.
The method broken pile heads using static blasting, the method can reduce construction noise and dust, and little to pile damage more.The built-in pipe of static blasting routine is only single straight pipeline, and weak effect is abolished in inconvenience powder charge when being embedded in pile crown, and medicament skewness.
Utility model content
The purpose of this utility model is to provide a kind of static blasting built-in pipe joint, and in common static explosion to be solved, built-in pipe is single, medicament technical problem pockety；And solve the problem that built-in pipe connects inconvenience, weak effect abolished by pile crown.
For achieving the above object, this utility model adopts the following technical scheme that a kind of static blasting built-in pipe joint, including charge housing, the main body of described charge housing is in the plat round box shape closed, the center of top of circle box is connected tube head connection with top, on the sidewall of described round box, hoop radial separation is communicated with side connection tube head, and described top connects tube head and side connects tube head and is short tube.
Described side connects tube head at least four.
It is metal or non-metallic rigid thin-walled material that described top connects the material of tube head, circle box and side connection tube head.
Compared with prior art this utility model has the characteristics that and beneficial effect:
(1) loading of static blasting medicament is facilitated.This utility model is just embedded in stake when pour stake body by concrete, and top connects tube head and connects with built-in pipe, can directly be put in built-in pipe by medicament when pile crown removed by needs.
(2) static blasting medicament distributing position is uniform, and static state is abolished effective.The connection of all built-in pipes can be got up by this utility model, by being connected the built-in pipe powder charge of tube head connection with top, is delivered to static blasting medicament be connected with side in the built-in pipe of tube head connection, makes the distribution of static blasting medicament more uniform, abolishes effect more preferable.
(3) noise when concrete is abolished and dust pollution are reduced.This utility model is reached the degree of cast-in-place concrete pile pressure break by the uniformly extruding of static blasting medicament, thus more effectively reduces noise when concrete is abolished and dust pollution.
(4) built-in pipe material is saved.This utility model makes static blasting built-in pipe obtain length can to intercept according to demand, decreases unnecessary built-in pipe waste.
This utility model can be widely applied to abolishing of concrete filling pile head in the various constructions such as building, bridge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Accompanying drawing illustrates: 1-top connects tube head, 2-circle box, 3-side connection tube head.
Detailed description of the invention
Embodiment is shown in Figure 1, a kind of static blasting built-in pipe joint, including charge housing, the main body of described charge housing is in the plat round box shape closed, the center of top of circle box 2 is connected tube head 1 with top and connects, on the sidewall of described round box 2, hoop radial separation is communicated with side connection tube head 3, and described top connects tube head 1 and side connects tube head 3 and is short tube.
Described side connects tube head 3 at least four, and in the present embodiment, side connects tube head 3 is eight.
It is metal or non-metallic rigid thin-walled material that described top connects the material of tube head 1, circle box 2 and side connection tube head 3.
Breadth Maximum of the present utility model is less than the diameter of cast-in-place concrete pile.
In this utility model, the built-in pipe length being connected tube head 3 connection with side can intercept according to the size of cast-in-place concrete pile diameter, be connected the pile crown length intercepting that the built-in pipe length of tube head 1 connection can cut as required with top.
Work process of the present utility model: this utility model is embedded in stake when pour stake body by concrete, top is connected tube head 1 and side connects tube head 3 and is connected with built-in pipe respectively, need after arriving some strength Deng pile body to remove pile crown, now static blasting medicament is put into and be connected, with pushing up, the built-in pipe that tube head 1 connects, static blasting medicament is delivered to be connected with side in the built-in pipe that tube head 3 connects after top connects tube head 1 and circle box 2, by the expansion extruded concrete pile crown of static blasting medicament, reach the degree of pile crown pressure break, thus abolish pile crown.
