Zusammenfassung:	The utility model relates to a module expansion device suitable for bridges in roads and city highways. The expansion device is characterized in that compression control springs of a displacement control system are installed in a positive-negative direction coupled mode, a displacement box is arranged, the compression control spring is arranged between supporting hangers, a reversed-installed compression control spring, a positive-installed compression control spring and a reversed-installed compression control spring are sequentially arranged on a gap between a boundary beam steel and a middle beam along a cross beam from left to right, or a positive-installed compression control spring, a reversed-installed compression control spring and a positive-installed compression control spring are sequentially arranged on a gap between a boundary beam steel and a middle beam along a cross beam from left to right. If a reversed-installed compression control spring is arranged in the front of two sides of the cross be
