Embodiment Construction

[0017] The following pages will further illustrate the present invention in conjunction with the accompanying drawings and specific embodiments.

[0018] see figure 1 One end of the steel pipe 1 is an open end and the other end is a closed end. The upper end of the rubber film 4 with a rough appearance is fastened and set on the outer upper end of the closed end of the steel pipe 1 with the upper fastening fastener 2, and the lower end is fastened and set on the closed end of the steel pipe 1 with the lower fastening fastener 5. At the outer lower end of the closed end of the steel pipe 1 , the film thickness of the rubber film 4 is 2-4 mm, and there are pores 3 on the part of the steel pipe 1 corresponding to the rubber film 4 .

[0019] see figure 1 After placing the bolt in the soft soil or sand formation 6, the steel pipe 1 is inflated under high pressure, the rubber film 4 at the end of the bolt expands under the high-pressure gas, and the surrounding soil is squeezed to...

Abstract

The invention discloses an inflatable anchor rod. One end of a steel tube (1) is an open end, while the other end is a closed end; the upper end and the lower end of a rubber film (4) with rough appearance are fastened and sleeved outside the closed end of the steel tube (1); and a part of the steel tube (1), which is corresponding to the rubber film (4), is drilled with air holes (3). The thickness of the rubber film (4) is between 2 and 4 mm. The invention is an inflatable anchor rod which can be directly used in soft soil regions without reinforcing soft soil, can provide all anchored force after the construction is finished, shorten the construction period, and has no pollution.

Description

technical field [0001] The invention relates to an anchor rod for supporting foundation pits in soft soil areas, which is mainly used for foundation pit support in soft soil and sandy soil layers. Background technique [0002] At present, other types of anchors commonly used at home and abroad, such as grouting anchors and resin anchors, cannot play a good anchoring role in soft soil areas. The soft soil needs to be reinforced to play an anchoring role, and grouting Anchor bolts need to wait until the grout reaches strength to provide full anchoring force, which pollutes the environment and takes a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an inflatable anchor rod that can be directly used in soft soil areas without reinforcing the soft soil, and can provide all the anchoring force after the construction is completed, shortening the construction period and causing no pollution. [0004] In order...
