Abstract
The utility model discloses an underwater elevation controller for a cast-in-place concrete pile, which structurally comprises a cast-in-place concrete pile. A reinforcement cage is arranged in the cast-in-place concrete pile, and an underwater pressure sensor is arranged on the reinforcement cage and connected with a ground pressure alarm through a metal lead led out of the top of the cast-in-place concrete pile. The underwater elevation controller for the cast-in-place concrete pile has the advantages that elevation of the top surface of the cast-in-place concrete pile can be controlled, so that the problems unresolved for a long time in the industry of 'disqualification of the pile due to too low elevation and waste of concrete due to too high elevation' and subsequent construction difficulty are solved.
Description
Technical field
The utility model relates to a kind of cast-in-place concrete pile absolute altitude controller under water.
Background technology
Present development along with builing industry; The applied more and more of cast-in-place concrete pile in construction work; But; The high control of the top mark of cast-in-place concrete pile is one of difficult point of engineering construction all the time, and absolute altitude crosses that low then to form pile body defective, the too high difficulty that then causes concrete waste and follow-up construction of absolute altitude.To so far, also there is not a kind of method preferably to solve this type of problem, most of construction enterprises can only guarantee pile quality to add the high method of timber pile top mark, and like this, have promptly wasted resource, have strengthened cost again.
The utility model content
The purpose of the utility model; It is exactly the problem that exists to above-mentioned prior art; A kind of cast-in-place concrete pile absolute altitude controller under water is provided, to overcome in the present building operations the high wayward and drawback that can't accurately reach predetermined absolute altitude of top mark on the cast-in-place concrete pile.
The technical scheme of the utility model is following:
A kind of cast-in-place concrete pile is the absolute altitude controller under water; Comprise cast-in-place concrete pile; Be provided with reinforcing cage in the described cast-in-place concrete pile; Described reinforcing cage is provided with pressure inductor under water, and described pressure inductor under water connects the pressure alarm that is arranged on ground through the metal lead wire of being drawn by described cast-in-place concrete pile top.Described pressure inductor is arranged on any reinforcing bar of said reinforcing cage.
The beneficial effect of the utility model is:
Predetermined position at said cast-in-place concrete pile adds pressure inductor under water; And through it deadweight changes the change value of pressure of being sensed and calculates the concrete height that need build to concrete and cement paste, to solve the control problem of cast-in-place concrete pile end face absolute altitude.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the cross section structure enlarged diagram of Fig. 1.
Mark among the figure: 1-reinforcing cage 2-cast-in-place concrete pile 3-is pressure inductor 4-pressure alarm 5-metal lead wire under water
The specific embodiment
For the utility model is understood more easily, it is done to specify below in conjunction with embodiment shown in the drawings.
With reference to accompanying drawing; The cast-in-place concrete pile of the utility model is the absolute altitude controller under water; Comprise the reinforcing cage 1 that is arranged in the cast-in-place concrete pile 2; Fixedly mount pressure inductor 3 under water on the described reinforcing cage 1, described pressure inductor under water 3 connects the pressure alarm 4 that is arranged on ground through the metal lead wire 5 of being drawn by the top of said cast-in-place concrete pile 2.
Fixing for ease, described pressure inductor 3 can be installed on any reinforcing bar that constitutes said reinforcing cage 1.
The mounting structure or the operating procedure of the utility model are following:
(1) measures the proportion of cement paste according to the soil property situation of said cast-in-place concrete pile 2 construction regions and precoat and build concrete proportion, measure the changing value of conducting oneself with dignity behind the said 3 predetermined installation position above concrete replacing water mud of pressure inductor under water simultaneously.
(2) described pressure inductor under water 3 is installed in predetermined position, and with itself and any reinforcing bar firm fixation that constitutes said reinforcing cage 1.
The metal lead wire 5 that (3) will connect said pressure inductor under water 3 draws and is mounted on the pressure alarm 4 on ground from the top of said cast-in-place concrete pile 2.
(4) begin the concreting castinplace pile, and in the process of building, keep watch on the reflection of said pressure inductor under water 3:
1. when concreting during to predetermined absolute altitude, the change value of pressure of described 3 reflection concrete of pressure inductor under water and cement paste;
When treating that 2. change value of pressure that described pressure inductor under water 3 is sensed reaches preset value, its signal is delivered to the pressure alarm 4 that is installed on ground through described metal lead wire 5;
3. described pressure alarm 4 is reported to the police, thereby stops concreting.
The utility model has the advantages that: the end face absolute altitude that can control cast-in-place pile concrete; Thereby solve the problem of unsolved for a long time " absolute altitude crosses that low then to form pile body defective, and absolute altitude is too high then to cause the concrete waste " of the industry and follow-up constructional difficulties.
Above with reference to accompanying drawing and embodiment to the cast-in-place concrete pile of the utility model under water the absolute altitude controller schematically describe, this description does not have restricted.Those of ordinary skill in the art will be understood that in practical application the shape of member and set-up mode all some change possibly take place, and other staff also possibly make similar Design under its enlightenment.Only it is pointed out that otherwise break away from the design aim of the utility model that all conspicuous change and similar Design all should be included within the protection domain of the utility model.
Claims (2)
1. cast-in-place concrete pile absolute altitude controller under water; Comprise cast-in-place concrete pile; Be provided with reinforcing cage in the described cast-in-place concrete pile; It is characterized in that, pressure inductor under water is set on the described reinforcing cage, described pressure inductor under water connects the pressure alarm that is arranged on ground through the metal lead wire of being drawn by described cast-in-place concrete pile top.
2. cast-in-place concrete pile according to claim 1 is the absolute altitude controller under water, it is characterized in that, described pressure inductor is arranged on any reinforcing bar of said reinforcing cage.
