Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer" etc. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation or in a specific way construction and operation, therefore, should not be construed as limiting the invention. The terms "first", "second", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] Such as figure 1 As shown, an integral concrete pouring trolley for the upper and lower layers and the middle plate of the ove...

Abstract

The invention discloses an upper-lower layer and overlapping section middle plate integral concrete pouring trolley. The upper-lower layer and overlapping section middle plate integral concrete pouring trolley comprises two lower-layer bottom beams at the bottom, a lower-layer steel frame is installed on the lower-layer bottom beams, a supporting device is installed on the positions, at the rear portion of the lower-layer steel frame, of the lower-layer bottom beams, an upper-layer steel frame is connected to the position, on the same side as the lower-layer steel frame, of the upper portion of the supporting device, and the upper-layer steel frame extends forwards out of the lower-layer steel frame. When a double-layer tunnel / tunnel hole is poured, the upper layer and the lower layer canbe constructed at the same time, construction efficiency is improved, and the construction progress of the double-layer tunnel is accelerated.

Description

technical field [0001] The invention relates to a trolley, in particular to a trolley for integral concrete pouring of upper and lower floors and middle plates in overlapping sections. Background technique [0002] In the process of excavating tunnels / tunnels, traditional trolleys are used to pour the second lining in a single layer. In the construction of double-layered tunnels / tunnels, when the upper and lower layers need to be poured with concrete, the conventional method is to pour the first layer first, then the first When the first layer reaches sufficient strength, the second layer can be poured, and the second lining can be poured on the second layer. This takes a long time and is less efficient. [0003] Therefore those skilled in the art devote themselves to developing a kind of integral concrete pouring trolley for the upper and lower floors and the middle plate of the overlapping section with high construction efficiency. Contents of the invention [0004] In...
