Description

Suspended large-span drainage device

Technical Field

The utility model relates to the technical field of foundation pit drainage in constructional engineering, in particular to a suspended large-span drainage device.

Background

The deep foundation pit is an engineering with excavation depth of more than 5 meters (including 5 meters) or depth of less than 5 meters, but geological conditions, surrounding environment and underground pipelines are particularly complex, and water body residues are very easy to generate due to infiltration of underground water in the deep foundation pit, so that water body is required to be discharged in time. At present, the dewatering and drainage of a deep foundation pit usually adopts a submerged pump to connect with a hose, and water in a pipe well is lifted to the ground for recharging or centralized treatment. According to the method, the hose is paved on the ground of the foundation pit, the field construction is influenced by the drain pipe in the foundation excavation process, the drain line is possibly damaged due to mechanical collision in the construction process, and the construction progress is influenced due to precipitation interruption.

Disclosure of Invention

In order to solve the technical problems, the utility model provides the suspended large-span drainage device, which is used for suspending a drainage pipe, so that the foundation pit drainage can be performed, and the construction is not influenced.

In order to achieve the technical purpose, the utility model adopts the following scheme:

the suspended large-span drainage device comprises a drainage pipe, a framework, a first support and an end support structure, wherein the drainage pipe and the first support are arranged in parallel, and the drainage pipe and the first support are fixedly connected through the framework; the end supports are of triangular structures and are arranged at two ends of the drain pipe and used for supporting a plane formed by the drain pipe, the framework and the first support so that the plane is perpendicular to the ground; the drain pipe and the first support are fixedly connected with the end support, and the end support is respectively erected on the ground on two sides of the foundation pit or on an upright post of a construction site, so that the drain device spans the foundation pit. The both ends of drain pipe are connected with the drain hose respectively, and the setting of skeleton and first support can prevent that the drain pipe from leading to the deformation because of the stride is big.

Further, the end support comprises a second support, an inclined support and a connecting rod, wherein the second support is arranged on two sides of the drain pipe in parallel, the second support and the drain pipe are fixedly connected through the connecting rod, and the second support and the first support are fixedly connected through the inclined support.

Further, the drain pipe adopts the steel pipe, and skeleton, first support and tip support are steel construction. The whole steel construction that adopts of drainage device can quick assembly disassembly, can guarantee its stability again.

Compared with the prior art, the utility model has the beneficial effects that:

the suspended large-span drainage device is erected above the foundation pit, and the drainage device spans across the foundation pit, so that drainage from the upper part of the foundation pit is realized, the drainage continuity can be ensured, and the construction in the foundation pit can not be influenced. The triangular end supports ensure the stability of the drainage device; the device wholly adopts the steel construction, can quick assembly disassembly, can guarantee again that device stable in structure, the security is high.
