The invention discloses a high-pressure jet grouting expansion hot-melting anchor bolt foundation pit supporting method. The high-pressure jet grouting expansion hot-melting anchor bolt foundation pit supporting method includes the steps that a bolt body is manufactured; a drilling machine is arranged in place; drilling construction is carried out; a spraying pipe is installed; guniting and broaching are carried out; an anchor bolt is placed; a sleeve is drawn out; grouting is carried out; stretch-draw locking is carried out; and a loose core is recycled. The high-pressure jet grouting expansion hot-melting anchor bolt foundation pit supporting method is convenient to construct and good in effect. In the construction process, high-pressure jet cutting is carried out on a certain length of soil, fixed to an anchor wall, of the bottom of the anchor bolt with liquid to achieve expansion, and cement paste or cement mortar is grouted to the bottom of an anchor hole, so that reinforcement is realized, and the technical characteristic of expansion reinforcement is formed. The high-pressure jet grouting expansion hot-melting anchor bolt foundation pit supporting method can be widely applied to the building construction engineering, road traffic engineering, hydraulic engineering and the like.
