Abstract
The utility model relates to a processing unit for processing the section of a concrete cast-in-place pile which is higher than a marked position with the object to solve the problems seen in the prior art. Currently, the higher positioned section of a cast-in-place pile is normally eradicated by a crusher or a drilling hammer with a sharp head or an air pick, which easily breaks the cast-in-place pile with the slightest neglect and makes the main bar in the reinforcing steel bar contained in the higher positioned section of the cast-in-place pile damaged or deformed. Thereby, the marked height of a cast-in-place pile can not be ensured even though great effort has been devoted and the quality of the constructions is not guaranteed, either. To solve these problems, the following measures are raised. The utility model comprises a compressed air hose, a compressed air branch hose, a compressed air source, a regulating master valve arranged on the compressed air hose, a pressure meter and a regulating valve connected to the compressed air branch hose. The utility model enables the materials composing concrete with different proportions to sink to different layers with the action of air while making the rest part of concrete less strong so as to be better processed. In this manner, the cast-in-place piles and the main bar contained therein are less likely to be damaged and the quality of cast-in-place piles is thereby effectively increased.
Description
Technical field
The utility model relates to underwater concrete filling pile head or wall top mark height such as bored pile or diaphragm wall, specifically belongs to the treating apparatus of the elevation-exceeding part of concrete pouring pile head.
Background technology
At present, the pouring pile head after underwater grouting finishes all is doped with laitance liquid and poor mud mostly on its pile crown.The existence of laitance liquid and poor mud will be very unfavorable to the quality of pouring pile head, to the building that will on this pouring pile head, build, will have very big harm.The constructor is the quality that guarantees pouring pile head and go up the building of building for this reason, the perfusion of taking to exceed setting mixes the measure of doubting about native pile crown 0.5-1.0m, after treating that pouring pile head finishes, to exceed the mixed part of doubting native pile crown of the filling that sets and root out, and the reinforcing bar master muscle that exceeds part is exposed.
Owing to root out is to adopt crushing engine or tip drilling hammer (pneumatic pick) to carry out mixed doubting when the soil stake reaches intensity, during operation, if carelessness is arranged slightly, just may make pile crown produce the crack, sometimes also may make the reinforcing bar master muscle that exceeds part produce damage or distortion, mix the absolute altitude of doubting native pile crown and cause guaranteeing to set perfusion, labour intensity is time-consuming greatly again, and can not guarantee workmanship.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, the treating apparatus that provide that a kind of perfusion that exceeds setting mixes that the part of doubting native pile crown absolute altitude is rooted out easily, the time spent is few, the reinforcing bar master muscle of exposed portions serve and pile crown is difficult for impaired concrete pouring pile head.Realize the technical measures of above-mentioned purpose:
The treating apparatus of concrete pouring pile head, it is: its by compressed gas house steward, the compressed gas arm that is connected with the compressed gas house steward and compressed gas source, compressed gas house steward go up the adjusting main valve installed and pressure meter, the control valve that connects on the compressed gas arm forms.
It is: the compressed gas arm is at least 1.
It is: the installation quantity of control valve is identical with the installation quantity of compressed gas arm, and is contained in the epimere of compressed gas arm.
It is: the requiring of the bottom of compressed gas arm and pouring pile head has 100～500 mm distance between the absolute altitude.
It is: the compressed gas arm in the installation site on the compressed gas house steward so that its in the scope that the main muscle of pouring pile head is set and even layout.
The utility model compared with prior art, it is owing to adopt Compressed Gas, make the material of the different compositions of each proportion in the concrete material under the effect of gas, produce separating layer, cause cement paste, sand, building stones produce segregation and reduce the intensity of redundance concrete greatly, the bottom that is separating layer is heavy building stones, the upper strata is the little cement paste of proportion, the intermediate layer is the sand material of proportion between building stones and cement paste, the part-structure feature that concrete placing pile crown after separating according to this compressed gas exceeds standard high, cause the processing of this part is easy to, and not easy damaged pouring pile head and main reinforcement, thereby effectively guaranteed the pouring quality of concrete pile crown, for follow-up construction engineering quality has been laid solid foundation.
Description of drawings
Fig. 1 is the structural representation of the treating apparatus of concrete pouring pile head
Fig. 2 is Fig. 1 scheme of installation at the scene
The specific embodiment
Be further described below in conjunction with accompanying drawing
This specific embodiment, the diameter of concrete pouring pile head are greater than 100 centimetres, and compressed gas arm 2 is installed as more than 2; When the diameter of concrete pouring pile head during less than 100 centimetres, compressed gas arm 2 is installed 1～2.
The treating apparatus of concrete pouring pile head:, near compressed gas house steward 1 epimere place a control valve 6 is installed at every compressed gas arm 2 in compressed gas house steward 1 welding or with the compressed gas arm 2 of be threaded 1/2/4/5 and even layouts; Distance is 100 millimeters/200 millimeters/300 millimeters/400 millimeters/500 millimeters between the designing requirement absolute altitude of the bottom of compressed gas arm 2 and pouring pile head; To can not produce inflammable and explosive compressed gas source 3 with compressed gas house steward 1 employing welding or with being threaded by the air or on-the-spot satisfactory other of air compressor machine compression; Difference setting pressure table 4 and hand are regulated main valve 5 on the compressed gas house steward 1.
Operating principle
Extract the back when concrete does not condense as yet from the concrete pouring pipe, compressed gas arm 2 is inserted in the concrete, when making compressed gas arm 2, according to its bottom and pouring pile head to require the distance between the absolute altitude be 100 millimeters/300 millimeters/500 millimeters demarcation, need not in the concrete to adjust so compressed gas arm 2 inserts; Successively open control valve 6 on the compressed gas arm 2 and the adjusting main valve 5 on the compressed gas house steward 1, making pressure is that the compressed gas of 0.3～1.0Mpa sprays towards periphery via the bottom of compressed gas arm 2; After concrete surface layer began to occur the mud bubble, in time adjusting main valve 5 on the priority closes compression gas house steward 1 and the control valve 6 on the compressed gas arm 2 stopped the input of compressed gas; Extract with being about to compressed gas arm 2 then; Part to the setting absolute altitude that exceeds pouring pile head is rooted out.
Compressed gas house steward 1 also can be used as the press water house steward, and promptly medium also can be press water except that compressed gas.
