摘要
Topic Joint job being simple, the dead water material for the expansion gap which possesses the endurance where the joint part is sufficient is obtained. SolutionsThe dead water material 20 for the expansion gap which is split into the crosswise of the road bridge has joint structure. Dead water material 20 for the expansion gap the dead water material itself to have 21 and sponge formation 23, sponge formation 23 adhesion on the end face of dead water material itself 21. Sponge formation 23 is low from the dead water material itself by compressed stress, at the same time, dead water function is shown as a whole, compressibility and the elongation percentage are high together. Depending, just makes two sponge formations fit 23 can the dead water material 20 for the expansion gap, joint dead water material itself 21 mutually. Choice figure Drawing 2
