Problems solved by technology

[0002] With the continuous development of my country's construction industry, construction land is becoming increasingly scarce, and the construction and development direction of various industries is gradually moving towards coastal areas, islands, and soft soil areas that are prone to collapse. Such areas are mostly sandy soil and soft soil foundations, and pile foundations and structures are constructed. Finally, the continuous construction of other surrounding facilities will cause the subsidence of the foundation of the structure, which will bring potential hidden dangers to the operation of the structure and later production facilities.

Embodiment Construction

[0014] like figure 1 As shown, the sandblasting reinforcement method of the suspended part of the structure adopts a compressed air sandblasting device to spray gravel to the suspended part of the structure 6. The sandblasting device is composed of a sandblasting pipe 2, a hose 3, a spraying device 1 and an air compressor 4; Before sandblasting, the grouting pipe 5 can be installed on the suspended part of the structure according to the needs. After sandblasting, sandblasting is carried out in the opposite direction of the previous sandblasting direction. A drip humidification device is installed in the sandblasting device to enhance the adhesion of the sand after spraying, so that the sand After spraying, it can be densely bonded together to form a soil foundation that meets the strength and load-bearing capacity, providing guarantee for the safe use of soft soil foundation structures that are prone to settlement and collapse and production and operation facilities.

Abstract

The invention relates to structures, in particular to a reinforcing method for a hanging portion of a structure. The sand-blasting reinforcing method for the hanging portion of the structure includes the steps that 1, an air compressor and a sand-blasting device are arranged around the to-be-reinforced structure, the air compressor passes through the sand-blasting device through a hose, and an outlet of the sand-blasting device communicates into the hanging portion of the structure through a sand-blasting pipe; 2, a grouting pipe is arranged according to the field; 3, sand gravel is added into the sand-blasting device, the air compressor is started, and sand-blasting is conducted; 4, the sand-blasting position is transferred, sand-blasting is conducted in the reverse direction of the original sand-blasting direction; and 5, grouting is conducted after the hanging portion of the structure is filled with sand. The sand-blasting reinforcing method provides guarantees for safety utilization of soft soil foundation structures which are liable to subside and collapse and production and operation facilities.

Description

technical field [0001] The invention relates to structures, in particular to a reinforcement method for suspended parts of structures. Background technique [0002] With the continuous development of my country's construction industry, construction land is becoming increasingly scarce, and the construction and development direction of various industries is gradually moving towards coastal areas, islands, and soft soil areas that are prone to collapse. Such areas are mostly sandy soil and soft soil foundations, and pile foundations and structures are constructed. Finally, the continuous construction of other surrounding facilities will cause the foundation subsidence of the lower part of the structure, which will bring potential hidden dangers to the operation of the structure and later production facilities. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a sandblasting reinforcement method for suspended parts...
