Detailed Description

The utility model is described in detail below with reference to the figures and examples.

Example (b):

the utility model provides an expansion joint with water conservancy diversion structure, as shown in figure 1, including drainage tube 1 and drainage branch pipe 2 of fixed connection in the expansion joint, drainage tube 1 and drainage branch pipe 2 fixed connection are also parallel on the horizontal direction to in its length direction many places intercommunication formation a plurality of intercommunication mouth one 5 and a plurality of intercommunication mouth two 6, sliding connection has slider 4 in drainage branch pipe 2.

As shown in fig. 1, 5 and 6, the drainage tube 1 and the branch drainage tube 2 are both in a long strip shape, 60Si2MnA steel is adopted, the drainage tube 1 and the branch drainage tube 2 are arranged in a length direction in an inclined manner, the branch drainage tube 2 is inclined upwards from a communication position between the branch drainage tube 1 and the branch drainage tube 2 along a width direction of the branch drainage tube, a groove 3 penetrating through the upper wall of the branch drainage tube 2 is formed in the top surface of the branch drainage tube 2, the length direction of the groove 3 is the same as the height direction of the branch drainage tube 2, the cross section of the sliding part 4 is trapezoidal, the inside of the sliding part is hollow, the density of the sliding part is smaller than that of water, the sliding part 4 is connected in the groove 3 in a sliding manner, the sliding part 4 protrudes into the drainage tube 1 from the groove 3, the first communication opening 5 is communicated with the second communication opening 6, and the height of the first communication opening 5 in the length direction of the drainage tube 1 is smaller than that of the second communication opening 6 communicated with the first communication opening.

Under the normal condition, the rainwater that flows into embedded drainage tube 1 in the expansion joint can flow along drainage tube 1, because drainage tube 1 is the slope setting, the velocity of water can be faster, remains the water in drainage tube 1 and also can become less, has reduced the probability that expansion joint department leaked, and slider 4 blocks up drainage branch pipe 2, and water just can not flow in drainage branch groove, has reduced the jam probability in drainage branch groove.
