Description

Artificial digging pile assembled retaining wall
Technical field
The utility model belongs to technical field of buildings, more particularly to a kind of artificial digging pile assembled retaining wall.
Background technology
Artificial digging pile is one of important pile mode, flexible with pile body diameter, at low cost, and construction efficiency is high The features such as, applying now commonplace.Artificial digging pile is first to carry out pore-forming using hand digging method, is then placed Steel reinforcement cage, pour into a mould concrete so that formed stake, but artificial digging pile because use hand digging mode, in mining process Hole wall easily collapses, and there is very big security risk, and the location of rich groundwater, needs a large amount of pump drainage underground water, easily triggers periphery Road and pipe settlement.
For traditional artificial digging pile generally using the cast-in-place retaining wall of reversely hung Yong, thickness is not less than 100mm.Retaining wall height is generally 1m is 0.3 ~ 0.5m when meeting local mobility mud and being likely to occur and gush when soil gushes sand.
JGJ 94-2008《Technical code for building pile foundation》" dismounting of dado template should be mixed in perfusion for the regulation of 6.6.10 It is solidifying soil for 24 hours after ".
At present, two kinds of ways are used on building site:
One group(2 people)Xun Huan excavates 2 hole stakes:4 fast ~ 5h completes a section retaining wall height, and the completes first one morning A hole stake first segment completes second hole stake first segment afternoon;First hole stake second of the next morning construction saves, construction in afternoon Average advance 1 that second hole stake second saves ... saves/d, and the effective time of concrete curing is 17 ~ 18h, partially dangerous.
Slow 8h or so completes a section retaining wall height, completes within first day first hole stake first segment, completes first within second day A hole stake first segment;First hole stake second is completed within 3rd day to save, complete within the 4th day second hole stake second and save ... it is average into 1 section/2d is spent, the effective time of concrete curing is 36 ~ 38h, relatively safety.
Another group(2 people)A hole stake is only excavated, the previous day completes breast wall concrete and pours, and morning removes support, Continuation is excavated down.Actual progress 1 saves/d, and the effective time of concrete curing is 10 ~ 12h, partially dangerous.
To sum up, the construction of concrete guard wall is the key that artificial digging pile pore-forming, traditional cast-in-situ construction method cannot and When be effectively formed support system, exist simultaneously the contradiction of safety and progress.I.e. conventional construction method is ensuring safe premise Lower progress is slow(Especially when soil condition is poor), it is partially dangerous on the premise of progress is ensured, and the dimensioning of pore-forming It is very little to be affected by formwork level.
The content of the invention
The purpose of this utility model is to provide a kind of artificial digging pile assembled retaining walls, solve traditional cast-in-place coagulation The construction method of native retaining wall cannot timely and effectively form support system, exist simultaneously the contradiction of safety and progress, this practicality is new Existing cast-in-place retaining wall is changed to prefabricated assembled retaining wall by type, meets the direction of 13 planning and development of construction industry, is ensuring to pacify On the premise of complete, speed up the work, reduce engineering cost.
The purpose of this utility model and its technical problem underlying is solved using following technical scheme to realize:A kind of people Work caisson assembled retaining wall, it is characterised in that:It is made of prefabricated components, auxiliary member and cast-in-place concrete three parts, prefabricated structure Part includes walling crib, well head and standard knot, is connected on the inside of walling crib for rounding entablature, walling crib with well head, well head is spelled by three pieces of arc panels It connects, well head top is equipped with multiple equally distributed sprue gate A;Standard knot is spliced by three pieces of arc panels, and standard knot top is uniformly set There are multiple sprue gate B;Connecting hole and preformed hole are all left on well head and standard knot;Auxiliary member includes timber wedge, vertical connecting hook, water Back nail, grouting tube finely tune retaining wall diameter between arc panel with timber wedge, by connecting hole with vertically between well head and standard knot Connect hook connects;The field cast-in-place concrete:Walling crib bed course, well head sit slurry, well head filling, standard knot filling, i.e., cast-in-place mixed Solidifying soil includes walling crib bed course, well head sits slurry(Mortar), prefabricated components(Well head, standard knot)Connector, fertile slot(Well head, standard knot)It fills out Plug.
The walling crib is integral manufacturing, thickness 5cm, outer diameter are that hole stake design diameter adds 40cm.
The well head specification be C30 armored concrete, thickness 5cm, height 50cm.
The standard knot specification be C30 armored concrete, thickness 5cm, height 25 ~ 50cm.
The vertical connecting hook makes of the short material of φ 10-14 reinforcing bars.
The horizontal nail subtracts for the anti-measure of collapsing when soil condition is poor, length control for hole stake design diameter 30cm is made using waste and old steel pipe, reinforcing bar, batten, is installed by preformed hole.
The grouting tube is for slip casting to use or as horizontal nail use, grouting tube φ during hole outside hole wall 48 steel pipe manufacturings, length control subtract 30cm for hole stake design diameter, are installed by preformed hole.
The utility model has clear advantage and advantageous effect compared with prior art.From above technical scheme, The utility model can realize factorial praluction, can accelerate than traditional cast-in-place retaining wall progress, more secure, the pore-forming matter of life safety Measure it is more reliable, construction it is more environmentally friendly.
