Embodiment 1

[0091] like image 3 As shown, the water jet holes are distributed according to 1+4, and one water jet hole 432b with a diameter of Ф8mm is set at the center of the bottom end of the conical tube 432, and the high-pressure water is sprayed vertically downward; the other four water jet holes 432a with a diameter of Ф6mm It is arranged on the upper end pipe wall of the tapered pipe 432, and its water jet direction is at an angle of 45° with the horizontal line or the axis of the water jet barrel 42 and the tapered pipe 432, and the high-pressure water is sprayed obliquely to the four sides.

[0092] There are two pairs of welded on the water jet gun head 43 such as figure 2 or image 3 The "aperture-preserving" steel rib 431 shown has the specifications: 5mm×112.5mm×150mm, and the steel rib 431 is radially and evenly welded on the water jet gun barrel 42 with an outer diameter of ≥50mm and ≤100mm at the same height. on the outer wall. The peripheral dimensions of the two opp...

Abstract

The invention relates to a device for inhibiting foundation soil from disturbing during removing of steel sheet piles and an application method of the device. The device comprises a water tank, a high-pressure water pump, a high-pressure soft tube and a water jetting gun. The water tank is connected with the high-pressure water pump by a connecting tube; an outlet end of the high-pressure water pump is connected with the high-pressure soft tube and is connected with the water jetting gun by the high-pressure soft tube; and a tail end of the water jetting gun is a water jetting gun head with a special structure. When being constructed and applied, other construction tools must be provided, including a hoisting device for hanging the water jetting gun to perform the punching operation, a steel sheet pile pulling device, proper yellow sands and a transport handcart. The soil body in the steel sheet pile is changed into yellow sands by devices such as the high-pressure water pump, the high-pressure soft tube, the water jetting gun and so on; thus, when the steel sheet pile is pulled out, the soil body is not taken out, meanwhile, the yellow sands can fill the gap produced during removing of the steel sheet pile immediately and effectively; the disturbing of the foundation soil is avoided and the environmental impact problem caused by removal of the steel sheet pile in the prior art is solved basically.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to the construction of foundation engineering and surrounding environmental protection, in particular to the construction of steel sheet pile enclosure engineering and the prevention and control of environmental hazards. devices and methods of application thereof. Background technique [0002] The foundation pit enclosure for underground engineering construction is a temporary retaining wall that bears the earth pressure and water pressure generated by the earthwork excavation of the foundation pit. There are many types of foundation pit enclosures, mainly steel sheet piles, reinforced concrete sheet piles, cement-soil mixing piles, concrete pouring piles and underground diaphragm walls. According to different environmental conditions and construction characteristics, various enclosure structures are selected for foundation pit engineering design. In recent years, cement-s...
