Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, but the present invention is not limited to these examples.

Example 1

In fig. 1-5, the utility model relates to a concrete gate mound slipform hydraulic construction equipment is provided with collar tie 1 outside the gate mound of pouring in advance, and collar tie 1 encircles the gate mound and forms confined whole, is the main part of whole device, highly confirms according to concrete setting time and glide time, and the width satisfies the construction work space, need widen at overhead beam 2 position, and platform steel sheet 13 is installed at collar tie 1 top. A plurality of groups of beam supports 3 are installed on 1 upper portion of collar tie beam about the width direction symmetry, and beam supports 3 are the structure of connecting overhead beam 2 and collar tie beam 1, respectively with

overhead beam
