Technical Field

[0001] The utility model relates to the technical field of engineering construction, and particularly relates to a filling and sealing perfusion device for the bottom and the outer side of a deep well during construction. Background Art

[0002] With the enhancement of environmental protection awareness, green building and green construction have become the development direction of building construction. In some construction projects near water bodies, due to the complexity of geological conditions, some soluble rocks may appear. During construction, it may be necessary to pass through some solution grooves, solution troughs and small karst caves. At this time, measures must be taken to prevent the water body from communicating with the karst cave and eliminate potential safety hazards. At the same time, construction in this geological environment will have some adverse effects on the water ecological environment. Therefore, it is necessary to develop a construction device that can adapt to this construction environment, improve safety indicators and reduce the impact on the construction and ecological environment. Content of the Utility Model

[0003] The purpose of the utility model is to provide a construction device that can adapt to the above construction environment, has a higher safety guarantee level and has little impact on the water ecological environment.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a filling and sealing perfusion device for the bottom and the outer side of a deep well during construction, including an inner casing, and a conduit is fixedly installed on the outer side wall of the inner casing through a positioning device.

[0005] Further, it also includes an outer casing, and there is a certain distance gap between the outer casing and the inner casing according to construction needs.

[0006] Further, the positioning device is a positioning hoop.

[0007] Further, the number of the conduits > 1, and they are evenly distributed on the outer side wall of the inner casing.

[0008] Further, it also includes a grouting device connected to the conduit.

[0009] Further, it also includes a funnel, the lower end of the funnel is connected with a central conduit, and the central conduit is located inside the inner casing.

[0010] The beneficial technical effects of the utility model are:

[0011] (1) Through the setting of the double-layer casing and the filling and sealing measures for the bottom and the outer side of the well pipe, the leakage path between the well pipe and the soil body is blocked, avoiding the communication between the water body and the karst cave during construction. The outer casing can be used as a support wall during perfusion, and grouting is carried out through the conduit between the inner and outer casings, ensuring the construction safety and also avoiding the impact on the water ecological environment;

[0012] (2) By setting multiple multi-point sidewall conduits, the utility model can precisely control the grouting process, ensuring the safety and accuracy of construction.

[0013] (3) The setting of the utility model can fill the sealing layer during construction, thereby enhancing the sealing and stability of the well pipe. BRIEF DESCRIPTION OF THE DRAWINGS
