Description

Inner and outer mould trolley lining system for open-cut underground canal

Technical Field

The utility model relates to a dig underdrain construction field deeply, refer in particular to an inside and outside mould platform truck lining system for open cut underdrain.

Background

The underground canal is a main structure for urban underground drainage, and the existing construction method of the underground canal comprises an underground excavation method and an open excavation method; the underground excavation method is that the ground is not excavated, and a hole is excavated underground; the underground excavation method has high construction difficulty, high engineering cost and poor safety in the construction process. The open cut method is a construction mode of digging the ground, digging out a foundation pit, then building an underdrain in the foundation pit, then filling soil back into the foundation pit and burying the underdrain, and the mode is generally used for shallow burying the underdrain. The open cut method has the advantages of multiple construction operation surfaces, high speed, short construction period, easy guarantee of the engineering quality, low engineering cost and the like.

In an airport or the like, the underdrain is required to be buried deep and have a large water discharge amount; considering the difficulty degree of construction, the open excavation mode is adopted to construct the underdrain, a deeper foundation pit is excavated firstly, and then the underdrain is constructed at the bottom of the foundation pit; because the existing underdrain is buried shallowly, the water discharge is small, and the cross section size of the underdrain is small, the existing underdrain generally pours the underdrain into a concrete pipe in advance through a mould, and then places the concrete pipe poured in advance to the bottom of a foundation pit to be buried. In the airport and other projects, because the underdrain requires large drainage, the size of the cross section of the underdrain is also large, and a concrete pipe cannot be directly poured by using a mould in advance, but the underdrain can be directly built at the bottom of a foundation pit. The large cross-sectional size of the underdrain makes the underdrain difficult to construct. Meanwhile, in the existing underdrain structure, the cross sections of the outer contour and the inner contour are rectangular; the underdrain structure disclosed in CN201120181671.4 has a square outer contour and a square cross-sectional shape of the drain channel. When the underdrain structure is buried underground deeply, problems occur in that the underdrain structure is not well stressed due to the square cross-sectional shape of the outer contour and the inner contour of the underdrain, a large amount of soil is pressed on the top of the underdrain, and the top of the underdrain bears large pressure due to deep burying, so that the top of the underdrain is easily collapsed, and the service life of the whole underdrain is shortened. To solve this problem, the underdrain roof is configured in an inverted U-shape to distribute the forces applied to the roof.

Because the top of the underdrain is arched, the cross sections of the inner contour and the outer contour of the top of the underdrain are both arc-shaped, so that the construction on site is more difficult and the grouting is inconvenient, and particularly, when the inner and outer molds of the underdrain are lined, the flatness of the inner and outer molds of the underdrain is difficult to ensure. Meanwhile, the inner and outer templates are lined by building the inner template and the outer template in the conventional construction mode, but the templates are difficult to build, the templates are required to be built again once each section of construction is built, and the templates are also very difficult to disassemble.
