Problems solved by technology

During the construction of the pipe gallery, concrete maintenance is an important link to ensure the quality of the concrete of the pipe gallery. After the construction of the concrete structure of the pipe gallery is completed, there will often be insufficient concrete strength and cracking of the concrete structure. In addition to the influencing factors such as raw materials and concrete mix ratio , Another important factor is that the water maintenance is not in place, so that the hydration reaction of the cement cannot be carried out normally, resulting in insufficient strength of the concrete structure of the pipe gallery, and large shrinkage deformation, forming shrinkage cracks
[0003] At present, in the construction of the pipe gallery, the concrete structure is mainly maintained by manual spraying of water directly with water pipes during the maintenance period. It is more convenient to sprinkle water on the outer wall of the pipe gallery, and the quality is easy to guarantee. However, the inner wall of the pipe gallery needs to look up and spray water, which is greatly affected by human factors. , during maintenance, water is often not fully sprayed to the inner wall of the entire pipe gallery, and leakage occurs, which cannot achieve a good health care effect and directly affects the quality of the concrete structure

no. 1 example

[0048] The first embodiment of the maintenance method of the mobile pipe gallery maintenance device proposed by the present invention includes the following steps:

[0049] When using the water source along the pipe gallery for water supply, connect the water source point to the water inlet pipe of the water tank, open the exhaust valve and water inlet valve, close all the water outlet valves of the water tank, and close the exhaust valve when water comes out of the exhaust pipe;

[0050] Open all the water outlet valves connected to the water tank and the door-type spray pipe, the door-type spray pipe starts to spray water, and move the base to spray water evenly on the inner wall of the pipe gallery.

[0051] After maintenance, close all outlet valves and inlet valves.

no. 2 example

[0052] The second embodiment of the maintenance method of the mobile pipe gallery maintenance device proposed by the present invention includes the following steps:

[0053] When there is no water supply pipe along the pipe gallery, use an external water source to fill the water tank;

[0054] Close the water inlet valve and open the exhaust valve of the water tank, open the water outlet valve of the pipeline where the water pump is located, and close the other water outlet valves;

[0055] Start the water pump, the water tank will supply water to the door-shaped spray pipe, and the maintenance and spraying of the pipe gallery can be carried out through the nozzle by moving the base;

[0056] After the maintenance is completed, close the valves that are open everywhere on the water tank (referring to the open exhaust valve and water outlet valve).

Abstract

The invention discloses a movable type pipe gallery maintenance device. The movable type pipe gallery maintenance device comprises a base, travelling wheels, a door-shaped spraying pipe and a water supply device, wherein the travelling wheels are mounted below the base; the door-shaped spraying pipe is mounted above the base; a plurality of spraying nozzles are mounted on a top end face and two side faces of the door-shaped spraying pipe and are used for spraying water to an inner wall of a pipe gallery; the water supply device is communicated with the door-shaped spraying pipe and is used for supplying water to the door-shaped spraying pipe. By adopting the movable type pipe gallery maintenance device provided by the invention, the inner wall face of the pipe gallery is conveniently comprehensively and uniformly sprayed with the water and maintained.

Description

technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a mobile pipe gallery maintenance device and a maintenance method thereof. Background technique [0002] The construction of urban underground comprehensive pipe corridors can improve the comprehensive carrying capacity of the city and the quality of urbanization development, which is conducive to increasing the effective investment in public products and creating a new driving force for economic development. During the construction of the pipe gallery, concrete maintenance is an important link to ensure the quality of the concrete of the pipe gallery. After the construction of the concrete structure of the pipe gallery is completed, there will often be insufficient concrete strength and cracking of the concrete structure. In addition to the influencing factors such as raw materials and concrete mix ratio , Another important factor is that the water maintenance ...
