With the adoption of the method, the economic benefit can be ensured, and the use safety can be improved; the sediment and underwater can be avoided flowing from a discharging hole into a working well during discharging a shield machine; the shield excavation can be performed smoothly; the wear of a shield end can be reduced, and the working efficiency can be increased.
Description
Technical field
The present invention is specially the technical method of a kind of bamboo reinforcement concrete filling pile at shield end well soil stabilization.
Background technology
Into and out of the critical process that hole end well strengthening construction is shield launching and arrival construction.Before shield launching, generally according to the stable case on stratum, hole, take treatment measures targetedly.Reservoir treating generally adopts method has: cement mixing pile, rotary churning pile, slip casting method, and SMW engineering method, freezing measure carry out stratum consolidation process.Select any method according to geology, underground water, covering layer, shield structure diameter, shield machine type, construction environment factor, also will should consider safety, application property, cost, schedule requirement simultaneously.Be in grit layer geological stratification in geology, in order to avoid silt particle when shield machine is appeared and underground water pour in active well from going out hole, ensure that shield driving is carried out smoothly, it has been decided through consideration and into and out of the stratum near the end well of hole, bamboo reinforcement concrete filling pile consolidation process has been carried out to shield structure.
Summary of the invention
Technical problem solved by the invention is the technical method providing a kind of bamboo reinforcement concrete filling pile at shield end well soil stabilization, to solve the problem proposed in above-mentioned background technology.
In order to achieve the above object, the present invention realizes by the following technical solutions: a kind of bamboo reinforcement concrete filling pile, at the technical method of shield end well soil stabilization, comprises the following steps:
(1) environmental analysis;
(2) develop programs;
(3) arrange out one piece of flat field ground, facilitate building platform;
(4) rigging up and gland pipe make drilling and forming hole, forbidden for preventing stake position, it is important in construction to reserve center and correct installation auger, to the rig having boring tower, the power of rig is first utilized to coordinate with neighbouring cage, drilling rod is moved and roughly locates, again with jack by frame jack-up, accurate 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 horizontal drill machine crossbeam, and be symmetrical on drill axis at tower top and pull on cable wind rope,
(5) lay bamboo reinforcement cage, put into conduit after fluid concrete inward, because mao bamboon is diametrically lower uneven, to note the colligation of whole bamboo mid portion in bamboo reinforcement cage process of binding to the maximum position of pile body center stressed, thus be conducive to ensureing that pile body is stablized, during perfusion, concrete does not interrupt, otherwise easily occurs pile breaking phenomenon;
(6), after drawing sleeve pipe being installed, after a period of time is fixing, pile quality is checked;
Further, boring described in step (1) is because bamboo is that large therefore its buoyancy of diameter of hollow structure and bamboo is much larger than the buoyancy of reinforcing bar, be difficult to directly insert in insertion sludge process and therefore reduce buoyancy in bamboo body boring means, thus successfully bamboo cage is in place.
beneficial effect:
The inventive method also improves use safety while guarantee economic benefit, and when shield machine can be avoided to appear, silt particle and underground water pour in active well from going out hole, ensures that shield driving is carried out smoothly, reduces the wearing and tearing of shield end, increase work efficiency.
Detailed description of the invention
Reaching object to make technological means of the present invention, creation characteristic, workflow, using method and effect is easy to understand, below in conjunction with the specific embodiment of the invention, setting forth the present invention further.
Case study on implementation one:
