Embodiment Construction

[0027] The present invention will be described in further detail below according to accompanying drawing:

[0028] according to figure 1 , figure 2 It can be seen that a pipe jacking surround grouting device is composed of steel cap 1, connecting bolt 2, outer nut 3, inner nut 4, positioning plate 5, steel casing 6, screw 7, water plug 8 and so on.

[0029] It is characterized in that: the outer end of the connecting bolt 2 is vertically connected with the steel cap 1, and the connection method is welding; the inner end of the connecting bolt 2 passes through the ring hole 11 of the positioning plate 5, and the inner nut 3 is screwed on the bolt 2 and the outer nut 4, which are respectively attached to the inside and outside of the positioning plate 5; the screw 7 passes through the outer wall of the steel sleeve 6, and is screwed in the circular hole with an internal thread at the end of the cross wing rod 11 of the positioning plate 5; The steel casing 6 is installed in t...

Abstract

The invention discloses a surrounding type grouting device for jacking pipes. The outer end of the connecting bolt is vertically connected with the steel cap, the inner end of the connecting bolt passes through the ring hole of the positioning plate, and an inner nut and an outer nut are screwed on the bolt. The nuts are respectively attached to the inner and outer sides of the positioning plate. The screws pass through the outer wall of the steel sleeve and are screwed into the internal thread at the end of the cross-wing rod of the positioning plate. The steel sleeve is installed in the installation hole of the grouting device. And use structural glue to fix on the top pipe wall. The structure is simple and easy to use. By setting a cap at the end of the installation hole of the grouting device to change the spraying direction of the mud, the mud is changed from a single point direct injection to a uniform spray along the plane of the pipe wall, which overcomes the large loss of vertical spraying mud and the It is difficult to form the ills of a closed mud collar.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and more particularly relates to a surrounding pipe jacking grouting device, which is suitable for drag-reducing grouting in long-distance pipe jacking construction. Background technique [0002] The pipe jacking construction technology is a non-excavation underground pipeline laying construction technology that uses hydraulic pressure as the power to jack the pipe jacking machine and the pipe joints to be laid underground one by one until the pipe jacking receiving well. With the acceleration of urbanization in my country, pipe jacking technology is widely used in the construction of underground pipe networks such as urban water supply and drainage, gas, electricity, and communications. In the design and construction of the pipe jacking method, in order to reduce the frictional resistance of the pipe jacking during jacking and the influence of the pipe jacking construction on th...
