Description

Be used for subway shield to construct section of jurisdiction hydrologic cycle maintenance system

Technical Field

The utility model relates to a maintenance system, concretely relates to be used for subway shield to construct section of jurisdiction hydrologic cycle maintenance system belongs to section of jurisdiction maintenance field.

Background

The subway shield segment is a main assembly component for shield construction, is an innermost barrier of a tunnel and plays a role in resisting soil layer pressure, underground water pressure and some special loads. Subway shield constructs section of jurisdiction generally by section of jurisdiction factory prefabrication production, mainly utilize the section of jurisdiction mould can the shaping after sealed casting concrete, in order to guarantee section of jurisdiction later stage intensity, generally take to go into the aquatic maintenance after the drawing of patterns, can natural maintenance section of jurisdiction after 7 days are supported to water.

A double-layer water culture system for precast concrete segments is disclosed in a patent with a publication number of CN 207172375U, and comprises at least eight water culture ponds which are sequentially connected and arranged, namely a pond I, a pond II, a pond III, a pond IV, a pond V, a pond VI, a pond V and a pond … …. As the water culture period of the pipe piece is 7 days, at least eight water culture ponds are arranged for the purpose that: one of them pond is supported to water does not fill water, uses as circulation turnover pond, and the section of jurisdiction is put into in proper order in other ponds according to a week 7 days, installs into water main and drainage main outside one side in pond is supported to water, and the setting of the main of intaking is in the top of drainage main, and the one end of the main of intaking and the one end of drainage main form respectively into water end and drainage end, installs the gate valve of intaking near water end department, installs the drain gate valve near drainage end department. The position of the water inlet main pipe corresponding to each water culture pond is connected with a water inlet branch pipe through a water outlet gate valve, and the water inlet branch pipe is communicated into the corresponding water culture pond, so that the on-off of the corresponding water inlet branch pipe is controlled through the water outlet gate valve to control the water inlet of the corresponding water culture pond. Wherein, need a turnover pond to circulate and use for arrange the water yield in other ponds and take out the section of jurisdiction, do the circulation usefulness, resource-wasting, area is big, and the operation is wasted time and energy.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a be used for subway shield to construct section of jurisdiction hydrologic cycle maintenance system, feedwater, drainage and the integration of pouring water, alone just can implement at the pump house, the system is simple, convenient operation.

For solving the above problems, the specific technical scheme of the utility model is as follows: the utility model provides a be used for subway shield to construct section of jurisdiction hydrologic cycle maintenance system, 2 above water-service ponds set up side by side, every water-service bottom of the pool portion all has secretly to bury the water service pipe, and the water service pipe other end extends to the pump house, and a plurality of water service pipes are parallelly connected, all meet with the drain pipe, and all pipelines of every pond are the same, through advance, the three process of drainage, pouring water of drainage valve control, all valves all set up in the pump house.

The water inlet pipe is communicated and connected with the tap water control valve, the water supply valve and the main water discharge valve, the water tank water pipe is communicated and connected with the water supply valve and the water discharge valve, and the whole system process is completed through the water pump and the valve switch.

The drain valve is close to the drain pipe compared with the water inlet pipe.

The utility model discloses the beneficial effect who brings does: the water supply, the drainage and the water pouring are integrated, one person can implement the method in a pump room, and the system is simple and convenient to operate.

Fig. 2 is a partially enlarged schematic view of fig. 1.

Detailed Description

As shown in figures 1 and 2, the water circulation maintenance system for the subway shield segment is characterized in that more than 8 water culture ponds 1 are arranged in parallel, a water service pipe 2 is buried in each water culture pond 1 in a hidden mode, the other end of each water service pipe 2 extends to a pump room, a plurality of water service pipes 2 are connected in parallel and are connected with a drain pipe 3, a valve 4 and a water pump 5 are arranged at the discharge end of the drain pipe 3, a water inlet pipe 6 is communicated with each water service pipe 2, a plurality of water inlet pipes 6 are connected in parallel and then are gathered to a tap water source, a water inlet valve 7 is arranged on each water inlet pipe 6, and a water drainage valve 8 is arranged.

The water inlet pipe 6 is communicated and connected with a tap water control valve 9, a water supply valve 7 and a main water discharge valve 4, the water tank water pipe 2 is communicated and connected with the water supply valve 7 and a water discharge valve 8, and the whole system process is completed through a water pump 5 and a valve switch.

A for subway shield constructs section of jurisdiction hydrologic cycle maintenance system controls feedwater, drainage and mutual water of pouring through water pump 5 and valve 4, valve 9, the pipe diameter of water service pipe 2, drain pipe 3 and inlet tube 6 is phi 160mm, and water pump 5 is the pipeline booster pump, and the discharge capacity is 160m to thin year/h.

A water supply process: if water is supplied to the No. 1 water culture pond, all the drainage valves 8 are closed, the water inlet valve 7 on the water inlet pipe 6 communicated with the water service pipe 2 of the No. 1 water culture pond is opened, the water inlet valve 7 corresponding to the rest water culture pond is closed, then the tap water switch 9 is opened, the valve 4 is closed, tap water enters the water service pipe 2 through the water inlet pipe 6 until the water amount in the water culture pond meets the requirement, water supply is realized, and the rest water culture ponds supply water in the same way.

And (3) a drainage process: if for the drainage in No. 1 water culture pond, all intake valve 7 are closed, and the running water supply source is closed, opens the drain valve 8 on the water service pipe 2 that corresponds No. 1 water culture pond, increases the velocity of flow through water pump 5, opens drain valve 4, realizes quick drainage, and other water culture pond drainage analogize with this.

Pouring water: if the pond is supported to No. 2 with the water in 1 pond, support the water drainage valve 8 that the pond corresponds with No. 1 pond and open, all the other water drainage valve 8 are closed, support the water intake valve 7 that the pond corresponds with No. 2 ponds and open, all the other water intake valve 7 are closed, close water intake valve 9, water drainage valve 4, start water pump 5, support water and pass through pipeline 2 and get into booster pump 5 in the pond is supported to No. 1 pond, through pipeline 6, support pond pipeline 2 through water supply valve 7, 2 and get into 2 ponds, water volume reaches the requirement in the pond until water support, realize pouring, other ponds are supported and are watered and analogize with this.

What has been described above is merely a preferred embodiment of the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications and improvements can be made, and shall be considered as belonging to the protection scope of the present invention.
