Abstract
The utility model discloses a new structure of water jetting continuous wall-producing equipment, which comprises an inlet pipe, a sullage pipe, a vessel with a shape like a box, a plurality of blades and a wire brush. The vessel is connected with both the inlet pipe and the sullage pipe, the blades and the wire brush are fixed on the vessel, and steels with a shape like a Chinese character ''gong'' are fixed on the corners of the vessel. The utility model has the advantages that the wall is continuous and high-caliber because of the wider width created by the steels which makes enough thickness to connect with a cut-off wall.
Description
Technical field
The utility model relates to a kind of water jetting ground-connecting-wall capstan engine new construction.
Background technology
Along with urban construction puts more effort, the country and people more and more recognizes the importance and the urgency of environmental protection, has proposed environmental protection slogans such as " protection water source, protection homes ", focuses on life, industrial refuse aspect as big or middle city; The discharging of chemical waste product that produces as industries such as steam power plant, printing press, tailing dam, metallurgy, chemical industry and industrial refuse, useless slurry all has antiseepage to handle problems in addition, as long as there be a little the leaking will polluted source.As the thorough draining-off sewage problem of exosmosing of the impervious wall of garbage sanitary filling field.Beijing garbage sanitary filling field impervious wall requires: (1) uniaxial compressive strength R
28〉=2.0Mpa; (2) coefficient of permeability K≤1*10
-7Cm/s; (3) modulus of elasticity＜1000Mpa; (4) wall thickness is greater than 25cm.Fig. 1 is existing capstan engine structure chart, water jetting is made the diaphragm wall principle: utilize pumping water under high pressure water inlet pipe 3 in box-shaped capstan engine 1, form high-speed jet, utilize hoist engine operation capstan engine 1 constantly to move up and down, impact downward pressure that aqueduct and capstan engine 1 weight own produces and capstan engine 1 time towards the time its cutter shear action, destroy soil layer construction and form top-down slotted eye, after trough inner water soil mixes, extract water and sand mixture out ground by dreg-drawing pipe 2 by inverse circulation pump, water and cohesive soil form slurry strengthened wall and prevent hole wall collapse simultaneously, final formation section is the slotted eye of rectangle, adopt conventional underwater rise-vertical conduit method fluid concrete behind the pore-forming, form I preface slotted eye; That utilizes capstan engine 1 side direction nozzle 4 (flushing first phase slotted eye concrete side) and wire brush 9 when making II preface slotted eye rinses, washes effect, and the concrete side end face of single preface slotted eye is cleaned, and makes one, second stage concrete connects closely the formation subterranean continuous imperviousing wall.
Impervious wall Evaluation of Durability index should be long-term anti-seepage effect, and the principal element that influences long-term anti-seepage effect is the globality of body of wall itself and the density of body of wall.Durability is mainly reflected on the anti-leakage and anti-corrosion performance of materials for wall.Promptly mainly show as boring pore-creating quality and pouring quality.And the pore-creating quality mainly is the joint processing.The quality that joint is handled is directly connected to integrality of wall.
By former capstan engine construction, the wall of getting all is equally thick along the construction axis, not tap and middle walls, all be more than or equal to 25cm, if during like this by the control of 4 ‰ (code requirement) hole deviation, when being 27.2m as if hole depth, deflection is 10.88cm at the bottom of the hole, overlap joint thickness is 14.12cm, does not overlap the requirement that thickness will reach 18cm at the bottom of satisfying the hole.
Summary of the invention
The purpose of this utility model is that the wall that the existing capstan engine of solution is got all is equally thick along the construction axis, and the technical problem of tap and middle walls does not provide a kind of water jetting ground-connecting-wall capstan engine new construction.For achieving the above object, the utility model is taked following design scheme:
Form by water inlet pipe, dreg-drawing pipe and box container, blade and wire brush, described box container is connected with described water inlet pipe, dreg-drawing pipe, described blade and wire brush are installed on the described box container, and four jiaos of described box container are connected with i iron.
The utility model has the advantages that: owing to have the structure of i iron to widen to become the width of joint behind the wall.Guarantee the overlap joint thickness of impervious wall, improved the globality of body of wall itself and the quality of body of wall.

The specific embodiment
Embodiment 1: as shown in Figure 2, form by water inlet pipe 2, dreg-drawing pipe 3 and box container 1, described box container 1 is connected with described water inlet pipe 2, dreg-drawing pipe 3, and four jiaos of described box container 1 are connected with i iron 5, i iron 6, i iron 7, i iron 8.Described i iron 5, i iron 6, i iron 7, i iron 8 are welded on the described box container 1.Described box container 1 is the hollow metal structure.
Embodiment 2: as shown in Figure 3, nozzle 4 and wire brush 9 are arranged on the described box container 1, also there are nozzle 4 and wire brush 9 in another side corresponding to described box container 1, the lateral width that described wire brush 9 is covered with described box container 1 comprises the width of described i iron, described wire brush 9 usefulness cutting machines cutting, and guarantee that the steel wire brush becomes pectination.
Embodiment 3: shown in Fig. 4,5, steel pipe 10, blade 11 are arranged on the described box container 1, described steel pipe 10, blade 11 are welded in the both sides of described box container 1, described blade respectively
