Description

Take braced system work well waterproof construction

Technical Field

The utility model relates to a building field of construction, concretely relates to take braced system work well waterproof construction.

Background

The traditional working well construction sequence is as follows: as shown in fig. 1, firstly, a water stopping column and a cast-in-place pile 1 are driven on the ground, and then, the cast-in-place pile 1 is dug downwards in the area enclosed by the cast-in-place pile; after a certain distance is dug downwards, a first enclosing purlin W1 begins to be poured in the well, then a certain distance continues to be dug downwards, then a second enclosing purlin W2 continues to be poured, the operation is repeated until the bottom of the well is dug, then a bottom plate begins to be poured at the bottom of the well, after the bottom plate is solidified, a formwork is started to pour a concrete well wall between the bottom plate and the last enclosing purlin, namely a first well wall at the bottom, after the first well wall is solidified, the enclosing purlin above the first well wall is detached (namely the enclosing purlin at the bottommost and the enclosing purlin at the fifth in the drawing), then a second well wall is poured between the first well wall and the second enclosing purlin with the reciprocal number (the bottom is upwards), after the second well wall is cured, the third enclosing purlin with the reciprocal number is detached, the formwork is repeated and the operation is repeated until the top plate construction of the working well is finished.

Above be traditional work well structure and construction process, the well body D of traditional work well is that the bottom plate pours gradually upwards, and this well body D is formed by concrete placement, and the problem that traditional work well construction exists is: when the well body D is poured upwards from the bottom, the enclosing purlins need to be detached one by one, and the problems that the construction period is prolonged, the labor cost of materials is increased, and construction wastes are produced due to the detachment of the enclosing purlins are solved.

In order to solve various problems caused by the fact that enclosing purlins need to be detached in the traditional working well construction, I begin to research and develop a new working well, the new working well is integrated with a supporting system (namely, the upper enclosing purlins and the lower enclosing purlins), namely, a well body D of the new working well comprises a structure formed by overlapping a plurality of enclosing purlins and a plurality of well walls, and the enclosing purlins are not detached; this kind of take braced system's working well can face the problem of infiltration at first, because each purlin is poured earlier, and each wall of a well is poured afterwards, consequently, can have the construction joint between the wall of a well and purlin, and the water of earth can get into the construction joint from bored concrete pile 1 and at last gets into in the well from the construction joint, causes the working well infiltration.

Therefore, the purpose of this patent application is in solving the working well of taking braced system, the problem of infiltration between each purlin and the wall of a well.

Detailed Description

The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 2 to 4, the waterproof structure of the working well with the support system comprises a well body, wherein the well body comprises a plurality of surrounding purlins 2 and a well wall 3, and the surrounding purlins 2 and the well wall 3 are sequentially and alternately overlapped and connected; and a lower waterproof structure is arranged between the lower end of the surrounding purlin 2 and the well wall 3 below the surrounding purlin, and an upper waterproof structure is arranged between the upper end of the surrounding purlin 2 and the well wall 3 above the surrounding purlin.

Specifically, as an optional implementation manner in this embodiment, as shown in fig. 3, the lower waterproof structure includes a waterproof strip 4; the waterproof strip 4 is arranged at the lower end of the enclosing purlin 2 so as to form sealing fit between the lower end of the enclosing purlin 2 and the well wall 3 below the enclosing purlin.

Specifically, as an optional implementation manner in this embodiment, as shown in fig. 3, the lower waterproof structure further includes a waterproof step formed at the upper end of the well wall 3; the waterproof step comprises an upper step surface 31 and a lower step surface 32, the upper step surface 31 is positioned on one side in the working well, and the waterproof strip 4 at the lower end of the enclosing purlin 2 is in sealing fit with the lower step surface 32.

The waterproof step can prevent water seepage from directly permeating into the well, and even if water seepage occurs, water seepage into the well can be prevented due to the fact that the upper step surface 31 is higher than the lower step surface 32.

On the other hand, the wall of a well 3 is poured through reinforced concrete at the later stage and is formed, the wall of a well 3 is when formwork is poured, pour into concrete in the position of last step 31, because the difference in height between last step 31 and the lower step 32, consequently, the lower step 32 department of the wall of a well 3 has higher pressure differential, when filling up concrete in the die cavity, the laminating that lower platform interface can be higher depending on pressure differential is enclosing purlin 2 bottom surface, the comparison of pouring of one side of lower step 32 is more tight, promote the leakproofness between enclosing purlin 2 bottom and lower step 32.

Specifically, as an optional implementation manner in this embodiment, the upper waterproof structure includes a water stop plate 5; the lower end of the water stop plate 5 is inserted into the upper end of the surrounding purlin 2, and the upper end of the water stop plate 5 is inserted into the upper well wall 3.

The utility model discloses a braced system has been merged into to the well body of working well, each enclosing purlin 2 of pouring of well body in the process of digging downwards that promptly the well body, enclosing purlin 2 is used for supporting the well body, prevents that the well body from subsiding, enclosing purlin 2 pours earlier when the well body is dug downwards, enclosing purlin 2 when pouring, 2 lower extreme of enclosing purlin predetermines the ring channel now, 2 upper ends of enclosing purlin predetermine stagnant water board 5, take enclosing purlin 2 to install waterproof strip 4 in the ring channel after solidifying; just pour the bottom plate in the shaft bottom when waiting to dig the shaft bottom, then supreme the beginning wall of a well 3 of pouring down in the right side, 3 upper ends of the wall of a well of pouring after form waterproof step, lower step face 32 and the waterproof strip 4 of enclosing 2 lower extremes of purlin are sealed to be cooperated, 3 lower extremes of the wall of a well and the cooperation of stagnant water board 5 (stagnant water board 5 inserts in the wall of a well 3 when the wall of a well 3 is poured), enclose 2 upper ends of purlin and pass through stagnant water board 5, the lower extreme realizes enclosing the waterproof sealing structure between purlin 2 and the wall of a well 3 through waterproof step + waterproof strip 4.

When the bottom plate of the well is connected with the bottommost well wall 3 in a sealing mode, the water stop plate 5 is preset on the bottom plate of the well in advance, and then the bottommost well wall 3 is poured, so that the water stop plate 5 is inserted into the well wall 3 to form a water stop sealing structure.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
