Benefits of technology

This technology allows for better support when constructing underground structures by utilizing an interchangeable joint between two components made up of different materials like stainless steel or aluminum instead of just one material altogether. By doing this, there are more stable connections than if they were done beforehand due to longer exposure time required during building operations.

Problems solved by technology

This technical problem addressed in this patents relates to ensuring proper designing and placement of an indoor shelter machine when constructing city tunnels with multiple layers of material such as steel plating or concrete structures without causing delays caused by previous workings.

Embodiment 1

[0049] Example 1: In the section from Xiangxicun Station to Wenjin Station of Shenzhen Metro Line 9, the mileage from the left line of the section is 498.56m, and the exit of the left line is Xiangxicun Station, which is a transfer station. There is a height difference in the floor of the riding section. In order to receive the construction when the shield arrives, the shield receiving steel platform needs to be set up. The size of the reserved hole at the shield receiving end well is 11.5×7.5m. The enclosure of the main structure adopts an underground diaphragm wall with a thickness of 1000mm.

[0050] The diameter of the shield machine that is used to enter the hole this time is φ6340; the length of the main body of the shield machine is 8650mm, and the length of the cutter head is 1650mm. The weight of the machine head is 320T.

[0051] Combined with the site conditions, Xiangxicun Station is a transfer station, and the height difference between the bottom of the shield tun

Abstract

The invention discloses a shield machine receiving steel platform which comprises a plurality of steel supporting upright posts, a thick steel plate and a steel bracket; under the condition that a medium plate structure is too late to construct, a steel upright post platform can be utilized for receiving a shield machine; a connecting system cross-welded and fixed by 20a I-shaped steels is adoptedamong the steel upright posts, so that the integrity is ensured to be formed among the steel upright posts, therefore, the stability is higher; the receiving bracket is welded with the 2-cm steel plate by adopting additionally-arranged I20a angle steels as an anti-slip stop block, so that the slippage of the shield machine is prevented, and the shield receiving safety is ensured.
