Method for fixing underwater lifting pump in river channel

Technical Field

The invention designs a method for fixing an underwater lifting pump of a river channel, which can improve the hydrodynamic force of the river channel, does not discharge river water outside, is convenient to install and maintain, and belongs to the technical field of urban water environment comprehensive treatment.

Background

Urban water environment management is an important content of pollution prevention and treatment and attack and defense. In 2015, water pollution prevention and control action plans ('ten items of water') and relevant contents of sponge city construction are provided, so that the targets and requirements of water environment pollution treatment and urban waterlogging drainage in China are clearly provided, and the solution of ecological environment problems such as regional water environment treatment and urban waterlogging drainage becomes urgent needs for improving the civilian and promoting the social harmony and stability, is also a strategic task which is important and urgent for the overall situation of socialist modernization construction in China and the long-term development of Chinese nations, and is urgent needs for changing economic development modes and building resource-saving and environment-friendly societies.

The urban water environment treatment follows the technical route of 'source control and sewage interception, endogenous treatment, ecological restoration and quality guarantee of running water', and has achieved a large score on the basis of vigorous and comprehensive treatment, and the black and odorous phenomenon is effectively restrained. The improvement of river channel hydrodynamic force is an important content of quality guarantee of running water, and the improvement faces to the installation and maintenance of a lifting pump in a river channel, particularly the installation and maintenance of the lifting pump of the river channel under the condition that the river water is not discharged outside.

Disclosure of Invention

In order to overcome the defects, the invention provides a method for fixing the underwater lifting pump of the river channel, which does not discharge river water and is convenient to install and overhaul.

In order to solve the problems, the method for fixing the underwater lifting pump in the river channel comprises the following steps:

arranging a sinking concrete pipe in the river channel;

a fixed platform is hung in the sinking concrete pipe through a chain;

a lifting pump is arranged on the fixed platform;

and an outer discharge hose of the lifting pump is fixed on the sinking concrete pipe.

Furthermore, still include many intervals set up the inside wall of concrete pipe and/or the spud pile of outside lateral wall one side sink, the upper and lower both ends of spud pile all stretch out the concrete pipe that sinks.

The system further comprises a plurality of fixed pile groups arranged on the side wall of the sinking concrete pipe at intervals, each fixed pile group consists of two fixed piles, one of the two fixed piles is arranged close to the inner side wall of the sinking concrete pipe, and the other fixed pile is correspondingly arranged close to the outer side wall of the sinking concrete pipe; the upper end and the lower end of the fixing pile extend out of the sinking concrete pipe.

Furthermore, the device also comprises a fixed block, wherein the fixed block is fixed at the upper end of the sinking concrete pipe through a fixed pile, and the upper end of the chain is fixed on the fixed block.

Furthermore, the fixed block, form by the iron sheet preparation, embedded two mounting holes with the spud pile looks adaptation, the fixed block insert on the spud pile, keep flat on the concrete pipe that sinks.

The method can improve the hydrodynamic force of the river channel in the river channel without discharging river water, and is convenient to install and maintain.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and not by way of limitation with respect to the scope of the invention.

In one embodiment, as shown in fig. 1 and 2. According to the fixing method of the riverway underwater lift pump, the sinking concrete pipe (1) is placed at the bottom of a river, and the fixed pile (3) is adjacent to the sinking concrete pipe (1) and inserted into the bottom of the river; the fixing block (4) is inserted into the fixing pile (3) and is horizontally placed on the sinking concrete pipe (1); the movable ring (5) is inserted into the fixed pile and is connected with the fixed platform (7) through a chain (6). The fixed platform (7) is provided with a lifting pump (2). The outer discharging hose (8) is connected with the lifting pump (2) and is connected with the hard pipe (10) through a flange (9).

Wherein, concrete pipe sinks (1), and it is concrete pipe, and the size selects different specifications according to river course depth of water, elevator pump (2), silt degree of depth to be (diameter x length): 800X 2500mm, 1000X 2500mm, 1500X 2500mm, 2000X 2500 mm. It vertically sinks to the river bottom and stands for 3-5 days. The height from the top of the sinking concrete pipe (1) to the water surface is not more than 500 mm.

Wherein the fixed pile (3) is closely adjacent to the sinking concrete pipe (1) and is inserted into the river bottom. The size of the lifting pump is 50mm, 100mm, 150mm and 200mm according to different specifications (diameters) of the weight of the lifting pump (2). The 2 adjacent submerged concrete pipes are respectively inserted into the river bottom and out of the river bottom, and 3 groups of the submerged concrete pipes (1) are uniformly inserted around the submerged concrete pipes. The depth of the fixed pile (3) inserted into the river bottom is not less than 1000 mm.

Wherein, the fixed block (4) is inserted into the fixed pile (3) and is horizontally placed on the sinking concrete pipe (1). The anchor pile is made of iron sheets, is embedded with double holes, and has the specification 15mm larger than the diameter of the anchor pile.

Wherein the movable ring (5) is inserted into the fixed pile (3). The fixed platform (7) is formed by welding iron sheets, the diameter of the fixed platform is 200mm smaller than that of the sinking concrete pipe (1), the fixed platform is concave, and the height of the top end of the concave is 200-500 mm.

Wherein, the lift pump (2) is arranged on the fixed platform (7), and the specification is determined by the lift water quantity and the measuring range.

Wherein, the outer discharge hose (8) is connected with a lift pump (9) and is connected with a hard pipe (10) through a flange.

The invention discloses a method for fixing an underwater lifting pump of a river channel, which is applied to a general river channel, wherein the thickness of soft sludge is not more than 2000mm, the water depth range is 1000-5000mm, the lifting pump can be installed and maintained under the condition of not discharging river water, and the hydrodynamic force of the river channel can be effectively improved.

Numerous specific details are set forth in order to provide a thorough understanding of the present invention. The foregoing description is only a preferred embodiment of the invention, which can be embodied in many different forms than described herein, and therefore the invention is not limited to the specific embodiments disclosed above.
