Abstract
The present invention relates to construction of diaphragm wall.Beach territory, a kind of river diaphragm wall enters the locking device of rock section, it comprises: one covers and the steel plate in gap between the diaphragm wall connected with expansion bolt and the rock of Foundation Pit wall, described steel plate is provided with one and is positioned at described gap and the Grouting Pipe of passing steel plate body, described Grouting Pipe is provided with switch valve, and port is provided with filter screen.Beach territory, river diaphragm wall enters an enclosure method for rock section, comprising: described locking device is arranged along the gap ring-type between diaphragm wall and rock; When pit earthwork is excavated to this position, use steel plate to get lodged in gap place, steel plate is positioned at the anchoring position of diaphragm wall and rock, in the middle of the expansion bolt then expansive mortar bag being pressed in steel plate anchoring place, is tightened by expansion bolt; Turn on diversion Grouting Pipe, after the freezing by expansion of expansive mortar bag, along the shape nature crimp of seam crossing, form a complete enclosed construction.This invention ensures that the sealing effect of ultra-deep foundation pit.
Description
Technical field
The present invention relates to construction of diaphragm wall, particularly relate to structure and construction method that beach territory, river diaphragm wall enters rock section.
Background technology
The soil layer in beach territory, river is along the river drift sand formation, silt clay layer, burning into sand argillic horizon, andesite layer, the Whirlwind tank continuous wall trench underground degree of depth can only reach andesite layer and burning into sand soil layer binding site, because bottom after continuous wall trench underground has the sediment of some, the absolute altitude of andesite layer is uneven, so can there is space at this position diaphragm wall and andesite joint portion, the pressure effect due to outside muddy water after excavation of foundation pit to this position there will be Piping phenomenon.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides beach territory, a kind of river diaphragm wall to enter enclosed construction and the construction method thereof of rock section.Manufacture craft of the present invention is simple, workable; Ensure that the sealing effect of ultra-deep foundation pit.
For solving the problem, beach territory, a kind of river diaphragm wall enters the locking device of rock section, between the rock that it is arranged on diaphragm wall and Foundation Pit wall, it comprises: the steel plate in gap between a covering diaphragm wall and the rock of Foundation Pit wall, this steel plate is connected with expansion bolt respectively with diaphragm wall and with the rock of Foundation Pit wall, described steel plate is provided with one and is positioned at described gap and the Grouting Pipe of passing steel plate body, and described Grouting Pipe is provided with switch valve, and port is provided with filter screen.
Described beach territory, river diaphragm wall enters the locking device of rock section, it also comprise be arranged on steel plate and diaphragm wall and and the rock of Foundation Pit wall between expansive mortar bag.
Described beach territory, river diaphragm wall enters the locking device of rock section, and described expansive mortar bag is loaded in the car inner tube of a tyre by the expansive cement mortar be stirred to be made.
Beach territory, river diaphragm wall enters an enclosure method for rock section, and it comprises described locking device, and comprises:
Described locking device is arranged along the gap ring-type between diaphragm wall and rock;
When pit earthwork is excavated to this position, use steel plate to get lodged in gap place, steel plate is positioned at the anchoring position of diaphragm wall and rock, in the middle of the expansion bolt then expansive mortar bag being pressed in steel plate anchoring place, is tightened by expansion bolt;
Turn on diversion Grouting Pipe, after the freezing by expansion of expansive mortar bag, along the shape nature crimp of seam crossing, form a complete enclosed construction.
Enclosed construction of the present invention is by steel plate, diversion injected hole, expansive mortar bag forms, steel plate is used to get lodged in gap place, steel plate is positioned at the anchoring position of diaphragm wall and andesite, diaphragm wall is pressed in and andesite steel plate anchoring place two is arranged in the middle of expansion bolt with ready expansive mortar bag, expansion bolt is tightened, turn on diversion Grouting Pipe, the horn mouth place of diversion Grouting Pipe is stamped dense mesh, play the effect of diversion resistance silt, after the freezing by expansion of expansive mortar bag, will along the shape nature crimp of seam crossing, form a complete enclosed construction, as needs slip casting can in the slip casting of diversion injected hole, if do not needed slip casting can valve-off at any time.Manufacture craft of the present invention is simple, workable; Ensure that the sealing effect of ultra-deep foundation pit.
Accompanying drawing explanation
Below, the present invention is further illustrated by reference to the accompanying drawings:
Fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1: beach territory, a kind of river diaphragm wall enters the locking device of rock section, between the rock 2 that it is arranged on diaphragm wall 1 and Foundation Pit wall, it comprises: the steel plate 3 in gap between a covering diaphragm wall 1 and the rock 2 of Foundation Pit wall, this steel plate 3 is connected with expansion bolt 4 respectively with diaphragm wall 1 and with the rock 2 of Foundation Pit wall, described steel plate 3 is provided with one and is positioned at described gap and the Grouting Pipe 5 of passing steel plate 3 body, described Grouting Pipe is provided with switch valve 6, and port is provided with filter screen.
Described beach territory, river diaphragm wall enters the locking device of rock section, it also comprise be arranged on steel plate 3 and diaphragm wall 1 and and the rock 2 of Foundation Pit wall between expansive mortar bag 8.
Described beach territory, river diaphragm wall enters the locking device of rock section, and described expansive mortar bag 8 is loaded in the car inner tube of a tyre by the expansive cement mortar be stirred to be made.
Beach territory, a kind of river diaphragm wall enters the enclosure method of rock section, along the gap ring-type between diaphragm wall and andesite, described locking device is set, steel plate width and diversion injected hole quantity are determined according to gap width and water burst situation, when pit earthwork is excavated to this position, steel plate is used to get lodged in gap place, the anchoring position that steel plate is arranged in diaphragm wall and andesite first loads cycle tube with the expansive cement mortar be stirred, form an expansive mortar bag, then diaphragm wall is pressed in and andesite steel plate anchoring place two is arranged in the middle of expansion bolt, expansion bolt is tightened, turn on diversion Grouting Pipe, the horn mouth place of diversion Grouting Pipe is stamped dense mesh, play the effect of diversion resistance silt, after the freezing by expansion of expansive mortar bag, will along the shape nature crimp of seam crossing, form a complete enclosed construction, as needs slip casting can in the slip casting of diversion injected hole, if do not needed slip casting can valve-off at any time.
