Water level observation well pumping system around the foundation pit

Abstract

The invention discloses an around-foundation pit water level observation well pumping system, which comprises a water pump arranged in an observation well, an electric wire for connecting the water pump with an external power distribution device and a drain pipe for communicating the interior of the observation well with an external drain system, wherein a first connecting pipe is buried in the ground between the observation well and the drain system, and the drain pipe is inserted into the first connecting pipe; a second connecting pipe is buried in the ground between the observation well and the power distribution device, and the electric wire is arranged in the second connecting pipe in a penetration way; a third connecting pipe is buried in each of the two sides of the ground at a wellhead of the observation well, and a connecting rod for suspending the water pump is inserted between the two third connecting pipes. According to the system, the drain pipe is concealed in the first connecting pipe buried in the ground, and the drain system is not required to be independently arranged; the electric wire is concealed in the second connecting pipe buried in the ground, so that the problem that the electric wire is arranged on the ground is solved; the drain pipe and the electric wire are both concealed, so that optimal drain and using effects are ensured.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a pumping system for a water level observation well around a foundation pit. Background technique [0002] The existing water level observation well pumping system around the foundation pit generally adopts the surface installation method. The main technology is: firstly locate the position and depth of the observation well, use a professional well turning machine to turn the hole into a well and bury the non-spun tube, and then install the yarn tube at the top of the wellhead. (that is, the elevation of the top of the construction road around the foundation pit) is built with bricks to form a square brick pier, and finally the water pump, water pipes and wires of the pumping system are installed. The wires also pass through the well and are connected to the distribution box in the form of open wires above the ground. In order to prevent the water pump from falling into the w...

Problems solved by technology

[0003] The disadvantages of this technology are: 1. Vehicle operation and construction progress: For the construction main road and the road surface is relatively narrow, and the driving line avoids the road surface where the water level observation well is not located, it hinders the operation of construction vehicles and indirectly affects the speed of construction progress; 2. Green construction: the pumping system of the water level observation well around the foundation pit needs to set up drainage pipes around the foundation pit separately to integrate the drainage of all observation wells into an integrated drainage system, resulting in waste of site and materials; 3. Safe and civilized: there are brick piers at the wellhead At a certain height, the manhole cover is made of multi-layer wooden cover plate and because the water pipes and wires pass through and are not sealed tightly, the wires and water pipes are exposed to mop the floor. For the situation where there is a large flow of people and frequent vehicle transportation on the construction site (especially at night when the construction light is weak) There is a great potential safety hazard, and at the same time, it causes a poor image of civilized construction
