Embodiment Construction

[0020] Examples see Figure 1-3 As shown, the heat pipe fixed force transmission bracket of this thermal shield tunnel is distributed on the inner wall of the tunnel at intervals. The tunnel is composed of 6 prefabricated segments 1, and the length is 1200mm. The heat pipe fixed force transmission support Including ring beam 2, fixing piece 3, upright column 4 and force frame 5, the inner wall of the tunnel is fixed by double arched fixing piece 3 with two circles of ring beam 2, and two or four upright columns 4 are fixed between the two circles of ring beams , the two ends of each column 4 are supported on both sides of the inner wall of the tunnel, and the front and rear sides of every two columns are respectively connected with a stress frame 5 for passing through the thermal pipeline.

[0021] The size of the steel column is 400X400X20 (mm). The material of the steel column is Q235 steel.

[0022] see Figure 3-4 As shown, the force frame 5 is composed of two square fr...

Abstract

The invention discloses a fixing force transfer bracket for a thermodynamic pipe in a thermodynamic shield tunnel, which is distributed on the inner wall of the tunnel at intervals. The tunnel is formed by combining prefabricated pipe pieces, two circles of ring beams are fixed on the inner wall of the tunnel by double-arched fixing pieces, two or four upright posts are fixed between the two circles of the ring beams, two ends of each upright post are supported on two sides of the inner wall of the tunnel, and front side and back side of each two upright posts are connected with a stressed frame used for passing through the thermodynamic pipe respectively. The fixing force transfer bracket solves the fixing problem of the thermodynamic pipe in the thermodynamic shield tunnel, so that the thermodynamic pipe can bear the horizontal push-pull force of pipes in the axial direction and the side direction. Under the action of the horizontal push-pull force, a fixing bracket system can evenly transfer the horizontal push force to six prefabricated pipe pieces. The prefabricated pipe pieces move evenly under the action of an external force, and simultaneously relative displacement is not produced among the prefabricated pipe pieces.

Description

technical field [0001] The invention relates to a positioning device for a thermal pipeline. Background technique [0002] During the operation of thermal heating, horizontal thrust will be generated along the axial direction (X axis) and lateral direction (Y axis) of the heat pipe. The design value of the horizontal thrust in X direction is 800KN, and the design value of Y direction force is 500KN, so The pipeline fixed force transmission bracket is used to bear the horizontal thrust of the thermal pipeline in the X and Y directions. The traditional thermal shallow buried tunnel is to construct the secondary lining structure of the thermal pipeline support and then perfuse the tunnel. This traditional support can be easily fixed in the secondary lining structure of the tunnel. However, in the construction process of the thermal pipeline of the thermal shield tunnel, there is no secondary lining structure after the construction of the thermal shield tunnel, so the fixing be...
