Abstract
The utility model discloses a device for sinking a hollow shell pile through high-pressure water jetting, comprising a water jetting pipe, wherein the upper end of the water jetting pipe is connected with a water supply rubber pipe, the lower end of the water jetting pipe is coaxially provided with a water-jetting connection pipe, and the water-jetting connection pipe is internally provided with an opening facing downward and a nozzle communicated with the water supply rubber pipe. The water jetting pipe is provided with at least two sections, two adjacent water jetting pipe sections as well as the water jetting pipe section on the lowermost end and the water-jetting connection pipe are respectively and fixedly connected with each other through adapter sleeves in threaded connection with the outer parts of the pipe sections and the connection pipe, and the water jetting pipe section on the uppermost end is externally provided with an annular baffle plate. The device provided by the utility model has the advantages of simple structure, and can be widely applied to the hollow shell pipe sinking constructions for foundation pit supporting in a soft soil foundation, reinforcing of an instable band slope, a flushing-prevention diverting retaining wall and the like, and when the device is used for construction, fewer construction machines are needed, so that the construction is convenient, the working efficiency is high, no damages is brought to the hollow shell pipe, and thus, the pipe pile can be reused.
Description
Technical field
The utility model belongs to the Construction of Civil Engineering technical field, particularly a kind of water jetting at high pressure sinking hollow shell pill device.
Background technology
In Construction of Civil Engineering; through regular meeting's sinking hollow shell pill in soft soil layer; conventional method adopts methods such as hammering, vibration, static pressure that reinforced concrete prefabricated hollow shell pill is squeezed in the weak soil layer; not only difficulty of construction is big but also required construction machinery is more for these methods; inefficiency, and cause pile body damage easily influence utilization again after the intensity of pile body and the dismounting; and also need to take to strengthen ground bearing pressure sometimes, to prevent sinking or inclination of construction machinery.
The utility model content
The utility model is in order to solve weak point of the prior art, provides a kind of and is easy to construct, high efficiency, can not damage the water jetting at high pressure sinking hollow shell pill device of pile tube.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: water jetting at high pressure sinking hollow shell pill device, comprise discharge jet, discharge jet discharge jet upper end is connected with the water supply sebific duct, the coaxial jetting tube connector that is provided with in discharge jet lower end is provided with opening and the nozzle that is communicated with the water supply sebific duct down in the jetting tube connector.
Described discharge jet is provided with at least two joints, and adjacent two joint discharge jets, the plain adapter sleeve pipe that all is spirally connected by their outsides between joint discharge jet and the jetting tube connector are bottom fixedlyed connected.
The one joint discharge jet outside, described the top is provided with ring-shaped baffle.
Adopt technique scheme, discharge jet and jetting tube connector are inserted in the hollow shell pill, the hollow shell pill upper end is provided with suspension ring, crane or other hanging devices are hung suspension ring and are guaranteed that hollow shell pill vertically transfers, the nozzle lower end is consistent with the hollow shell pill height, high-pressure hydraulic pump provides flow dynamic by the water supply sebific duct for nozzle, nozzle ejection goes out water under high pressure soil layer is destroyed, and mixing formation mud overflows ground from bottom to top from the hollow shell pill outer wall, cause hollow shell pill bottom unsettled and sink, the sinking speed of discharge jet and jetting tube connector and hollow shell pill is consistent, and realizes the purpose of not damaged pile sinking; Because pile tube is longer, this just needs the axial connection of more piece discharge jet just can reach the length of pile tube, adjacent two-section discharge jet and the use plain adapter sleeve pipe fixing mode that is spirally connected between joint discharge jet and the jetting tube connector bottom are easy to dismounting, and can keep axiality preferably; Ring-shaped baffle is positioned at the hollow shell pill top, and diameter is greater than the hollow shell pill internal diameter, and in the sinking process, ring-shaped baffle is crimped on the hollow shell pill upper surface, can guarantee discharge jet and jetting tube connector and the synchronous sinking of hollow shell pill like this.
The utility model is simple in structure, when construction, do not need too many construction machinery, be convenient to construction, high efficiency, hollow shell pill is had no damage, guarantee that pile tube can utilize once more, can be widely used in the sinking construction operation of hollow shell pills such as pattern foundation pit supporting structure in the soft foundation, the reinforcing of bank slope unstability, water conservancy diversion erosion control shore protection.
Description of drawings
