Therefore, by the steel plate for sealing water 2 arranged along the width total length of coercion underground continuous wall, hydro-expansive rubber band 1 and rubber packing 10, thus define three road waterproofing courses in the stitching portion of upper and lower two width coercion underground continuous wall, can effectively prevent the water of coercion underground continuous wall side from flowing into the opposite side of coercion underground continuous wall through the stitching portion of upper and lower width coercion underground continuous wall, be conducive to coercion underground continuous wall do not do all the other process can directly use as outer wall of basement, save construction cost, be conducive to popularization and the utilization of Precast Diaphragm Wall.
In addition, in the vertical splicing construction of above-mentioned coercion underground continuous wall, described protuberance 4 is arranged at and is positioned at below on a width coercion underground continuous wall, and due to the cross section of described protuberance triangular in shape, therefore, when the upper and lower two width coercion underground continuous wall of splicing, above a width coercion underground continuous wall can under the effect in deadweight along the described protuberance 4 of a width coercion underground continuous wall below described domatic on automatic attaching, precise positioning, so, the installation effectiveness not only improved, and ensure that installation accuracy.
In addition, in order to improve bonding strength between upper and lower two width coercion underground continuous wall and reliability, preferably, in the vertical splicing construction of above-mentioned coercion underground continuous wall, after upper and lower two width coercion underground continuous wall vertically splice, described tension rib 5 pre-buried in notch extends near the bottom land of corresponding notch.
Please continue to refer to Fig. 1 to Fig. 4, the construction method of the vertical splicing construction of coercion underground continuous wall of this enforcement is as follows:
The first step, a fixing width coercion underground continuous wall below.
Second step, the top of lifting width coercion underground continuous wall width coercion underground continuous wall below described above.
3rd step, above a width coercion underground continuous wall under the effect of deadweight along the domatic automatic attaching of described protuberance 4, precise positioning.
4th step, by injected hole 7 toward notch slip casting, concreting 11 in the chamber that notch corresponding is up and down formed, makes upper and lower two width coercion underground continuous wall compact siro spinning technology.Certainly need in advance to arrange template at two ports of notch.In addition, the slurries injected toward injected hole 7 can add additive, to increase the concrete intensity in stitching portion, improve the connection reliability between two width coercion underground continuous wall further.
The vertical splicing construction of coercion underground continuous wall of the present utility model, on the one hand, upper and lower two width coercion underground continuous wall are fastened togather by protuberance 4 and recess 5, and slip casting in the cavity up and down corresponding notch formed by injected hole, and be embedded in this three measures of tension rib in notch in advance, effectively can transmit the internal force of upper and lower two width ground-connecting-walls, make between upper and lower two width coercion underground continuous wall, form reliable connection; On the other hand, because coercion underground continuous wall is provided separately, reduce length and the weight of single width coercion underground continuous wall, be applicable to transport and lifting, again because the size of spliced coercion underground continuous wall entirety can significantly increase, because this increasing the coercion underground continuous wall excavation of foundation pit degree of depth applicatory, making it to be applied to and comparing use in existing darker foundation ditch, there are good economic benefits; Again on the one hand, because the cross section of described protuberance is triangular in shape, therefore, when the upper and lower two width coercion underground continuous wall of splicing, a width coercion underground continuous wall can along the domatic automatic attaching of described protuberance under the effect in deadweight above, precise positioning, the installation effectiveness not only improved, and ensure that installation accuracy.
