Description
Technical field
The utility model belongs to Subway Tunnel ventilating shaft space enclosing structure, specifically a kind of Subway Tunnel power line downcast deep foundation ditch combined enclosure structure.
Background technology
China's city underground siding-to-siding block length, more than 1600 meters, just must establish ventilating shaft, and the ventilating shaft degree of depth is comparatively dark, and long interval general Dou Shilishi center is comparatively far away, and ground high-tension electricity is more.Current domestic interval ventilating shaft is boring fender post substantially, but when there being high-tension electricity above interval ventilating shaft, if directly adopt boring fender post, need to set up protection canopy, not only have a big risk, cost is high, and needs to reequip equipment, and work efficiency is low.The at present also not i.e. safe but also space enclosing structure of easy construction.
Summary of the invention
The utility model, in order to solve the problem that existing Subway Tunnel high-tension electricity downcast construction risk is large, cost is high, working procedure is complicated, provides a kind of Subway Tunnel power line downcast deep foundation ditch combined enclosure structure.
The utility model takes following technical scheme: a kind of Subway Tunnel power line downcast deep foundation ditch combined enclosure structure, comprise the circle drilled pile bottom the foundation ditch below power line, drilled pile top is connected with Guan Liang, in hat beam, side stay has concrete support, be provided with a circle catchwater outside hat beam, be provided with a circle outside catchwater and put slope section spray anchor wall, put slope section spray anchor wall by anchor rod anchored, put and to be provided with outside slope section spray anchor wall that a circle is anti-floods wall, anti-flooding outside wall is provided with infrared rays height-limiting alarm.
The described gradient of putting slope section spray anchor wall is 1:1.
Described puts slope section spray anchor wall toe elevation higher than groundwater level 1 meter.
The utility model construction sequence is as follows: first carry out putting slope excavation with Miniature digging machine, and carry out shotcrete, until put slope to excavate in groundwater table 1 meter; Then infrared rays height-limiting alarm is utilized to carry out drilled pile construction; Finally carry out Guan Liang and concrete support, form combined enclosure structure.
Compared with prior art, the utility model has following beneficial effect:
1) first carry out putting slope with Miniature digging machine to excavate in groundwater table 1 meter and carry out bolt-spary supports, be not only drilled pile and construction space is provided, construction safety, and cancel protection canopy, reduce construction cost.
2) utilize infrared rays height-limiting alarm, after putting slope, drilled pile construction is carried out on ground, not only do not need to reequip equipment, accelerating construction progress greatly, and reduce the merogenesis of stake, greatly simplify working procedure.
The utility model makes full use of puts the advantages such as construction safety height is large behind slope, not only accelerating construction progress, reduces construction cost, and guarantees construction safety, simplifies working procedure.Have that technique is simple, advanced technology, the advantage such as practical.

Detailed description of the invention
As shown in Figure 1, 2, a kind of Subway Tunnel power line downcast deep foundation ditch combined enclosure structure, comprise the circle drilled pile 6 bottom the foundation ditch below power line 1, drilled pile 6 top is connected with hat beam 9, and in hat beam 9, side stay has concrete support 7, is provided with a circle catchwater 5 outside hat beam 9, be provided with a circle outside catchwater 5 and put slope section spray anchor wall 4, put slope section spray anchor wall 4 by anchor pole 3 anchoring, put and to be provided with outside slope section spray anchor wall 4 that a circle is anti-floods wall 2, anti-flooding outside wall 2 is provided with infrared rays height-limiting alarm 8.
Described, the gradient of putting slope section spray anchor wall 4 is 1:1.
Described, put slope section spray anchor wall 4 toe elevation higher than groundwater level 1 meter.
During concrete enforcement, comprise the following steps:
Step one, soil nail wall space enclosing structure is constructed.
A, ground are built by laying bricks or stones and prevents flooding wall; B, ground erection infrared rays height-limiting alarm; C, put slope by the 1:1 gradient and excavate more than phreatic line 1 meter; Anchor is sprayed in time after D, construction anchor pole.
Step 2, bored pile structure construction.
A, under toe, build catchwater; B, the stake of employing reverse circular technique construction drill; Excavation is continued after C, construction Guan Liang and concrete support.
