Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses waterproof construction of construction joint node. Referring to fig. 1 and 2, the waterproof structure of the construction joint node includes a water-swellable rubber strip 1 disposed between a first wall 10 on which casting is performed first and a second wall 11 on which casting is performed later, and a fastening plate 3 for reinforcing a connection relationship between the first wall 10 and the second wall 11.
After the first wall 10 is poured, a closed ring-shaped caulking groove 2 is formed in the wall surface of the first wall 10, which is required to be in contact with a new wall, namely the second wall 11, and then the water-swelling rubber strips 1 are arranged in the caulking groove 2. And a plurality of grooves 4 are formed on the peripheral sides of the outer ring and the inner ring of the caulking groove 2, and then the second wall body 11 is poured.
In the pouring process, the concrete for pouring the second wall body 11 enters the groove 4, so that the formed second wall body 11 forms the convex block 5 embedded into the groove 4 on the surface abutted to the first wall body 10, and the connection tightness between the first wall body 10 and the second wall body 11 is enhanced.
Meanwhile, after the concrete is contacted with the water-swelling rubber strip 1, the water-swelling rubber strip 1 swells, the second wall body 11 which is not solidified and the caulking groove 2 reserve a space for the swelling of the water-swelling rubber strip 1, and the influence on the connection relation between the first wall body 10 and the second wall body 11 in the swelling process of the water-swelling rubber strip 1 is avoided as much as possible.
Referring to fig. 1 and 3, after the second wall 11 is initially set, the composite geomembrane layer 7 is attached to the first wall 10 and the second wall 11 near the construction joint, and then the cement mortar layer 6 is coated outside the composite geomembrane layer 7.
The composite geomembrane has good water absorption, when water seeps at the construction joint, the composite geomembrane can absorb the seeped water, and meanwhile, the cement mortar layer 6 plays a role in sealing the construction joint, so that the possibility of water seepage of the wall surface is further reduced.
Because meet water inflation when water inflation rubber strip 1 seeps water in construction joint department, in order to avoid meeting water inflation rubber strip 1 when the inflation, influence the compactness of being connected between first wall 10 and the second wall 11, be provided with a plurality of mounting plates 3 on first wall 10 and the second wall 11 jointly. The two sides of the first wall 10 and the second wall 11 in the length direction of the construction joint are both provided with fastening plates 3, and the fastening plates 3 are arranged at equal intervals along the length direction of the construction joint.
Referring to fig. 1, wear to be equipped with many double-screw bolts 8 jointly on two mounting plates 3 that the face is relative, threaded connection has two nuts 9 on the single double-screw bolt 8, many double-screw bolts 8 divide the both sides of arranging construction joint length direction, double-screw bolt 8 pierces through first wall body 10 or second wall body 11, double-screw bolt 8, nut 9 is taut with first wall body 10 and second wall body 11 with mounting plate 3 cooperation, and make the connection of first wall body 10 and second wall body 11 more inseparable, further avoided the water stop rod of water-swelling when the inflation, produce the influence to the connectivity of first wall body 10 and second wall body 11.
After all the constructions are finished, the surface of the cement mortar layer 6 between the fastening plates 3 is coated with anhydrous copper sulfate solution to form an anhydrous copper sulfate layer, and the anhydrous copper sulfate turns blue when meeting water, thereby playing a role of warning when water seeps at the construction joint.
The implementation principle of the waterproof structure of the construction joint node in the embodiment of the application is as follows: be located 1 water inflation of water-swelling rubber strip between first wall body 10 and the second wall body 11, fill the construction joint, closed loop caulking groove 2 makes water-swelling rubber strip 1 also form closed loop, the sealing effect to the construction joint has been strengthened, caulking groove 2 has left the inflation space of reservation for water-swelling rubber strip 1, avoid water-swelling rubber strip 1 to influence the relation of connection between first wall body 10 and the second wall body 11 at the inflation in-process as far as possible, and simultaneously, mounting plate 3 has further strengthened the relation of connection of first wall body 10 and second wall body 11, thereby the compactness of being connected between first wall body 10 and the second wall body 11 when having guaranteed water-swelling rubber strip 1 inflation as far as possible.
