Abstract

The utility model discloses a kind of bamboo concrete stake, stress frame in pile body is bamboo reinforcement cage, pile body is built moulding by cement concrete, the principal rod of bamboo reinforcement cage is Ф 100mm mao bamboon, stirrup is bamboo chip, pile body cement concrete label used is C30, beneficial effect: what the utility model provided is a kind of bamboo concrete stake, replace reinforcing bar with bamboo reinforcement, greatly reduce engineering cost, be mainly used in the end soil body stabilization works of the good shield structure turnover of geological conditions hole, easily excavating property and economy are the main features that bamboo concrete stake is better than other reinforcing mode, make it to be applicable to TBM, mechanized constructions such as shield structure and can not damage cutter.Can be widely used in shield tunnel end soil body strengthening construction.

Description

A kind of bamboo concrete stake
Technical field
The utility model relates to a kind of concrete pile, particularly a kind of bamboo concrete stake.
Background technology
In recent years, along with a large amount of construction of underground construction, mechanized construction degree improves constantly, and new technology, new technology are adopted by numerous domestic engineering successively.In underground construction, generally adopt bored pile to construct, Grouting Pile Engineering of Drilling Hole exists that amount of reinforcement is large, engineering cost is high, and some provisional protection engineering adopts the more problems such as bored pile form is difficult for excavating in the time excavating.
Summary of the invention
The purpose of this utility model is a kind of bamboo concrete stake that has more problem in existing Grouting Pile Engineering of Drilling Hole work progress and provide in order to solve.
Stress frame in the pile body of the bamboo concrete stake that the utility model provides is bamboo reinforcement cage, and pile body is built moulding by cement concrete.
The principal rod of bamboo reinforcement cage is Ф 100mm mao bamboon, and stirrup is bamboo chip.
Pile body cement concrete label used is C30.
The construction method of the bamboo concrete stake that the utility model provides, concrete grammar is as described below:
The first step, construction process:
Its construction process is: flat field ground → lay working platform → rigging up → gland pipe → drilling and forming hole → lay bamboo reinforcement cage → put conduit → fluid concrete → drawing sleeve pipe → inspection pile quality;
The control step of second step, work progress:
A, first to ensure that mounting foundation is firm, to the more soft acclive ground in stratum, be bulldozed with bulldozer, being padded with steel plate or sleeper reinforces, in construction, first to reserve the center of stake position and correct installation auger, to there being the rig of boring tower, first utilize the power of rig to coordinate with near cage, drilling rod is moved and carries out Primary Location, again with jack by frame jack-up, accurately location, make gin wheel, the hole clipping of drill bit or fixing drilling rod and casing center are on a vertical line, to ensure the verticality of rig, the deviation of rig position is not more than 2cm, behind align piles position, with tie plate flat drill machine crossbeam, and be symmetrical on rig axis and pull on cable wind rope at tower top,
After b, clear hole are complete, prefabricated bamboo reinforcement cage is vertically hung onto in hole, behind location, will be fixed, then use tremie concrete, when perfusion, concrete will be built continuously;
In c, bamboo reinforcement cage process of binding, the colligation of whole bamboo mid portion to be arrived to the position of pile body center stressed maximum;
In d, construction, bamboo reinforcement cage bottom added to weight or the mode of bamboo body boring is reduced to buoyancy, thereby smoothly bamboo reinforcement cage being in place.
The beneficial effects of the utility model:
What the utility model provided is a kind of bamboo concrete stake, replace reinforcing bar with bamboo reinforcement, greatly reduce engineering cost, be mainly used in the end soil body stabilization works of the good shield structure turnover of geological conditions hole, easily excavating property and economy are the main features that bamboo concrete stake is better than other reinforcing mode, make it to be applicable to the mechanized construction such as TBM, shield structure and can not damage cutter.Can be widely used in shield tunnel end soil body strengthening construction.
Brief description of the drawings
Fig. 1 is the utility model section structure schematic diagram.
1, pile body 2, bamboo reinforcement cage 3, principal rod 4, stirrup.
Detailed description of the invention
Refer to shown in Fig. 1:
Stress frame in the pile body 1 of the bamboo concrete stake that the utility model provides is bamboo reinforcement cage 2, and pile body 1 is built moulding by cement concrete.
The principal rod 3 of bamboo reinforcement cage 2 is Ф 100mm mao bamboon, and stirrup 4 is bamboo chip.
Pile body 1 cement concrete label used is C30.
The construction method of the bamboo concrete stake that the utility model provides, concrete grammar is as described below:
The first step, construction process:
Its construction process is: flat field ground → lay working platform → rigging up → gland pipe → drilling and forming hole → lay bamboo reinforcement cage → put conduit → fluid concrete → drawing sleeve pipe → inspection pile quality;
The control step of second step, work progress:
A, first to ensure that mounting foundation is firm, to the more soft acclive ground in stratum, be bulldozed with bulldozer, being padded with steel plate or sleeper reinforces, in construction, first to reserve the center of stake position and correct installation auger, to there being the rig of boring tower, first utilize the power of rig to coordinate with near cage, drilling rod is moved and carries out Primary Location, again with jack by frame jack-up, accurately location, make gin wheel, the hole clipping of drill bit or fixing drilling rod and casing center are on a vertical line, to ensure the verticality of rig, the deviation of rig position is not more than 2cm, behind align piles position, with tie plate flat drill machine crossbeam, and be symmetrical on rig axis and pull on cable wind rope at tower top,
After b, clear hole are complete, prefabricated bamboo reinforcement cage 2 is vertically hung onto in hole, behind location, will be fixed, then use tremie concrete, when perfusion, concrete will be built continuously;
In c, bamboo reinforcement cage 2 process of binding, the colligation of whole bamboo mid portion to be arrived to the position of pile body 1 center stressed maximum;
In d, construction, bamboo reinforcement cage 2 bottoms added to weight or the mode of bamboo body boring is reduced to buoyancy, thereby smoothly bamboo reinforcement cage 2 being in place.
