Embodiment Construction

[0016] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0017] The connection method of the rubber waterstop of the present invention adopts the connection mode of cold vulcanization, and it comprises the following steps:

[0018] Step 1: Polish the bonded surfaces of the connecting ends of the two connected rubber waterstops to make them smooth, and the polished bonded surfaces will not have a smooth surface. Preferably, in step 1, when grinding the bonding surface of the connecting end of the connected rubber waterstop, fix the corresponding connecting end on the backing plate, which makes the grinding smoother and more convenient; when grinding, it is not possible Let the grinder stay in the same place for too long to avoid the high temperature caused by grinding to damage the rubber waterstop; the polished bonding surface should be kept dry and free from grease, dus...

Abstract

The invention provides a method for connecting rubber waterstops. The method comprises the following steps of: 1, firstly, polishing bonding faces at connecting ends of two rubber waterstops to be connected to evenness; 2, uniformly coating mix glue on the bonding faces of the two rubber waterstops respectively, and waiting until the mix glue on the bonding faces is dried to reach a specified requirement; and 3, finally, sticking the bonding face of one rubber waterstop to the bonding face of the other rubber waterstop so as to press-fit and bond the two bonding faces in an aligned manner. A cold vulcanization connection manner is adopted in the invention, during construction, no special heating equipment is needed; the method is simple in a construction process, can be easily mastered by constructors, has a lower requirement on construction environment and is simple and convenient to operate; and the connected rubber waterstops are greatly improved in firmness and low in cost.

Description

technical field [0001] The invention relates to the field of rubber waterstops, in particular to a connection method for rubber waterstops. Background technique [0002] At present, the vulcanized connection of rubber waterstops (especially tunnel rubber waterstops) adopts the method of hot vulcanization connection. The hot vulcanization connection method includes the following steps. The vulcanized connecting machine is preheated to 130-150°; the second step is to cut and polish the waterstop; the third step is to cut 10cm wide raw rubber joints and 1cm wide rubber connecting strips; the fourth step , turn off the preheating welding machine, and spread the waterstop joint on the bottom plate of the welding machine; the fifth step, put the 1cm wide rubber joint in the middle of the joint; the sixth step, lay the 10cm wide raw rubber joint On the polished joint, ensure that the width of both sides of the joint is equal; the seventh step, close the hot melt machine, tighten t...
