Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-9, the labels 1-14 are respectively shown as: the water storage device comprises a water storage container 1, a pump room section 2, a water collecting ditch 3, a pump pit 4, a shield tunnel 5, a central ditch 6, a water pump 7, a concrete substrate 8, a floating road bed plate 9, a groove area 10, a water pump installation reserved opening 11, a water drainage pipe groove 12, a cable groove 13 and a substrate structure 14.
Example (b): as shown in fig. 1 to 7, the built-in pump room structure of the shield tunnel floating slab track bed section of the present embodiment should be disposed in the pump room section 2 of the shield tunnel floating slab track bed section. The pump room section 2 refers to a section part divided from the shield tunnel floating slab track bed section, and the section part is used as a pumping and draining pump room section in the shield tunnel floating slab track bed section.
The built-in pump room structure in the embodiment comprises a water storage container 1 and a water collecting ditch 3 arranged in the pump room section 2, wherein the water storage container 1 and the water collecting ditch 3 are both arranged below a floating road bed plate 9 in the pump room section 2. A pump pit 4 is arranged in the water collecting channel 3, and the depth of the pump pit 4 is larger than the width and the depth of the water collecting channel 3. The water storage container 1 is attached to the inner walls of the water collecting ditch 3 and the pump pit 4 and is communicated with a central ditch 6 of other sections in the shield tunnel 5; a water pump 7 is arranged in the water storage container 1, and the water pump 7 is connected with a drain pipe. Ponding in the shield tunnel flows into in the retaining container 1 through central ditch 6, and when the water level in the retaining container 1 was higher than the predetermined value, water pump 7 extracted the water in the retaining container 1 to concentrate the discharge shield tunnel of water through the drain pipe.
Specifically, as shown in fig. 1 to 5, the water collection trench 3 is provided along the axial direction of the shield tunnel. Concrete bases 8 are arranged on two sides of the bottom of the pump room section 2, and the concrete bases 8 are used for bearing a floating road bed plate 9. The concrete base 8 is attached to the inner surface of the shield tunnel 5 and connected in a rib-planting mode. Two sides of the floating track bed plate 9 are erected on the concrete base 8 through vibration isolators. In the pump room section 2, two concrete bases 8 are arranged in parallel, and a certain distance is formed between the two concrete bases. The two opposite sides of the concrete foundation 8 and the inner surface of the shield tunnel 5 enclose a water collection channel 3.
As shown in fig. 1 to 9, the water collecting channel 3 is provided with a pump pit 4 at regular intervals, the bottom of the pump pit 4 extends downwards, and a concave structure is formed on the inner surface of the shield tunnel 5. The bottom of the pump pit 4 is lower than the bottom of the catch basin 3. The water pump 7 in the water storage container 1 is arranged in the groove area 10 where the water storage container 1 is attached to the pump pit 4. Because the bottom of pump pit 4 is less than the bottom of catch basin 3, therefore the water level in the recess region 10 of retaining container 1 is higher for the ponding condition in the shield tunnel can be rapidly reflected through the water level in the recess region 10, thereby guarantees the treatment effeciency of water pump 7, shortens its response time. The water pump 7 is connected with a water level sensor which is arranged in the groove area 10, and when the water level in the groove area 10 where the water pump 7 is located is higher than the pump starting water level, the water level sensor controls the water pump 7 to operate to extract accumulated water in the water storage container 1.
The central gutter 6 is provided in a section of the shield tunnel 5 other than the pump house section 2. As shown in fig. 6, the floating track slab 9 is supported on the base structure 14 by vibration isolators, while still using the floating track slab in this section. The base structure 14 is different from the concrete base 8 of the pump room section 2, the base structure 14 is an integrated structure, and the central ditch 6 is arranged in the middle of the upper surface of the base structure 14 and extends along the axial direction of the shield tunnel 5. The height of the bottom surface of the central gutter 6 is greater than that of the bottom surface of the catchment gutter 3 so that the accumulated water in the central gutter 6 can smoothly flow into the interior of the reservoir provided in the catchment gutter 3.
In the embodiment, in specific implementation: the water storage container 1 is of a groove shape and can be made of composite materials, the top of the water storage container is provided with an opening, and the edge of the opening at the top of the water storage container is connected with the floating road bed plate 9 through flexible materials. The water storage container 1 can prevent metal parts in the tunnel from being corroded due to long-term accumulated water in the shield tunnel.
A water pump installation reserved opening 11 is formed in the floating road bed plate 9. The water pump installation reserved port 11 is positioned right above the pump pit 4. The floating track bed plate 9 is provided with a drainage pipe groove 12 for accommodating a drainage pipe and a cable groove 13 for accommodating a cable. The drain pipe groove 12 and the cable groove 13 are communicated with the water pump installation reserved opening 11. The drain pipe is connected to the water pump 7 through a drain pipe groove 12 to form a drain line, and the cable is connected to the water pump 7 through a cable groove 13 to supply power for the operation of the water pump 7. The cables and the drain pipes are arranged along the side face of the inner wall of the shield tunnel, extend from the water pump installation reserved port 11 to the groove area 10 through the floating track bed plate 9 and are connected with the water pump 7.
Although the present invention has been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made without departing from the scope of the invention as defined in the appended claims, and therefore they are not to be considered in a repeated detail herein.
