Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure: preformed pile 1, pressure-bearing platform 2, drawing mechanism 3, tension platform 4, stretching reinforcing bar 5, axially main muscle 6, layer of concrete 7, breach 8, transverse reinforcement 9, pressure-bearing post 10, operating space 11.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, a kind of tension checkout gear of preformed pile, comprise the drawing mechanism 3 above the preformed pile 1 that is arranged on and is embedded in soil layer, a pressure-bearing platform 2 is provided with above described preformed pile 1, drawing mechanism 3 is positioned on pressure-bearing platform 2, drawing mechanism 3 is installed with a tension platform 4, pressure-bearing platform 2 has offered some perforation, passed the perforation on pressure-bearing platform 2 after stretching reinforcing bar 5 is fixedly connected with the main muscle 6 of axis of preformed pile 1 inside and be fixedly connected with tension platform 4.Drawing mechanism 3 is oil cylinder or jack.Oil cylinder or jack carry pressure meter, can read force value or value of thrust, and this is common practise, repeats no more herein.Stretching reinforcing bar 5 can weld with axial main muscle 6 or be fixedly connected with fixtures such as bolt pairs.Pressure-bearing platform 2 and tension platform 4 can make with concrete structure or cylinder iron, bloom etc.If when tension platform 4 is for mixed clay structure, can be embedded in tension platform 4 with attaching nut, make stretching reinforcing bar 5 and attaching nut be spirally connected fixing or be welded and fixed, if tension platform 4 is ironwork, stretching reinforcing bar 5 directly can be welded with tension platform 4.
The quantity of the perforation on pressure-bearing platform 2 is not less than the quantity of axially main muscle 6 on preformed pile 1, bore a hole according to the axially topological shape setting of main muscle 6 on preformed pile 1, as axially main muscle 6 is arranged ringwise, then bore a hole and be also preferably annular, as axial main muscle 6 is square setting, then boring a hole, it is square to be also preferably set to, by that analogy, described stretching reinforcing bar 5 and axial main muscle 6 one_to_one corresponding form cage construction after also boring a hole, and it is inner that described drawing mechanism 3 is positioned at the cage construction formed by stretching reinforcing bar 5.
The axial line of drawing mechanism 3 and the axial line of preformed pile 1 are located along the same line thus make tension platform 4 uniform force, and preferably, the axial line of drawing mechanism 3, preformed pile 1 and tension platform 4 all on the same line.Have some pressure-bearing posts 10 of being fixedly connected with pressure-bearing platform 2 bottom pressure-bearing platform 2 thus make to form operating space 11 below pressure-bearing platform 2, convenient operation is constructed.
Operating principle of the present utility model is: according to the position of preformed pile 1 in underground, cut out the soil layer at preformed pile 1 top until expose preformed pile 1, a pressure-bearing platform 2 is set up above preformed pile 1, drawing mechanism 3 to be placed on pressure-bearing platform 2 and the axial line of the axial line of drawing mechanism 3 and preformed pile 1 on the same line, drawing mechanism 3 is installed with a tension platform 4, pressure-bearing platform 2 offers some perforation, pass the perforation on pressure-bearing platform 2 after stretching reinforcing bar 5 is fixedly connected with the main muscle 6 of axis of preformed pile 1 inside and be fixedly connected with tension platform 4, starting drawing mechanism 3 stops drawing mechanism 3 to boost when the force value of drawing mechanism 3 arrives the tension standard value of preformed pile 1, now as rising does not appear in preformed pile 1, show that the tensile value of preformed pile 1 is qualified, then show that the tensile value of preformed pile 1 is defective as rising appears in preformed pile 1.Drawing mechanism 3 is oil cylinder or jack.
The quantity of the perforation on pressure-bearing platform 2 is not less than the quantity of axially main muscle 6 on preformed pile 1, described stretching reinforcing bar 5 and axial main muscle 6 one_to_one corresponding form cage construction after also boring a hole, and it is inner that described drawing mechanism 3 is positioned at the cage construction formed by stretching reinforcing bar 5.
When preformed pile 1 is positioned at below layer of concrete 7, excavate layer of concrete 7 and form breach 8, the shape of breach 8 does not limit, as long as preformed pile 1 can be exposed, the inwall of breach 8 cuts a hole into rough structure, interrupts the transverse reinforcement 9 in layer of concrete 7 and makes to be extended outside breach 8 inwall by the end of the transverse reinforcement 9 interrupted.When later stage rehabilitating concrete layer 7, the transverse reinforcement 9 interrupted can be welded one to one with other reinforcing bars, and the inwall of breach 8 is cut a hole into rough structure and is convenient to be formed with the concrete newly inserted be engaged, and recovers the structure of original layer of concrete 7 as much as possible.
When cut out the soil layer at preformed pile 1 top and the top of the water level of underground water higher than preformed pile 1 time, borehole thus make the top of preformed pile 1 be exposed to soil layer outside again after preformed pile 1 over top pours into cement or cement paste makes the soil layer at preformed pile 1 top solidify.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the term such as preformed pile 1, pressure-bearing platform 2, drawing mechanism 3, tension platform 4, stretching reinforcing bar 5, axially main muscle 6, layer of concrete 7, breach 8, transverse reinforcement 9, pressure-bearing post 10, operating space 11 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
