Abstract
A freezing method for building the continuous underground wall suitable for deep fundation pit includes artifically freezing the ground layer to form a frozen ground wall, manually or mechanically digging slots under protection of said frozen ground wall, and casting concrete walls in said slots. Its advantages are simple technology, high speed, and no need of sludge to protect wall surface.
Description
One, technical field
The present invention relates to diaphragm wall frozen construction worker method, be particularly useful for dark, thick construction of continuous concrete wall such as heavy construction deep foundation ditch, large-scale bridge pier deep foundation ditch, also be applicable to other carrying in moisture or caving ground or the construction of water proof body of wall.
Two, background technology
Municipal administration, traffic at present, traditional construction of diaphragm wall in the fields such as construction work, be in the slotted eye digging process, to adopt mud off, under mud, carry out cast of wall section concrete and the construction of wall section joint, though can finish the excavation work of slotted eye, body of wall shape and physical dimension are prone to deviation, walls concrete is prone to nest mud, folder mud phenomenon, grooving equipment is poor to the adaptive capacity of complex geological condition, and the joint quality between each wall section also is difficult for guaranteeing; Then need large-scale or expensive plant equipment to finish for dark, thick construction of continuous concrete wall, its slurry coat method also causes environment pollution easily.
Three, technology contents
1. goal of the invention
In view of the deficiency that prior art exists, the purpose of this invention is to provide a kind of easy construction, diaphragm wall physique amount is easy to guarantee, and is free from environmental pollution, excavates effective diaphragm wall frozen construction worker method.
2. technical scheme
Diaphragm wall frozen construction worker method of the present invention is finished like this: at first adopt artificial stratum freezing process, a distance, the slotted eye outside in the diaphragm wall section of intending construction, freezing of certain density of constructing with boring, in these borings, frigo is installed, provide cold to frigo, make its Freezing stratum as rapid on every side, and form the frozen soil wall that reaches designing requirement, promptly artificial stratum freezing process forms frozen soil wall; Then under the protection of formation frozen soil wall, artificial or Mechanical Method construction slotted eye, last in the slotted eye that construction is finished concreting, and couple together with adjacent wall section.Drilling depth should surpass diaphragm wall design maximum degree of depth certain distance.
3. technique effect
Diaphragm wall frozen construction worker method of the present invention is best suited for dark, thick construction of continuous concrete wall such as heavy construction deep foundation ditch, large-scale bridge pier deep foundation ditch.Adopt artificial stratum freezing process to form frozen soil wall (comprise and freeze rock), under the protection that forms frozen soil wall, the slotted eye of artificial or mechanical means driving and masonry construction wall section, concreting wall section in slotted eye is then handled the joint of wall section simultaneously well.Compare with traditional construction, it is simple that this diaphragm wall frozen construction worker method has construction technology, construction equipment is easy, but multiple spot is constructed simultaneously, and speed of application is fast, the diaphragm wall of can construct under various the complex geological conditions various degree of depth and thickness, need not mud off, the mud-less pollution problem is dry operation, and wall construction quality and wall section joint construction quality are easy to control and guarantee.For dark, thick construction of continuous concrete wall, this method has special advantage, and has practicality widely.
Four, the specific embodiment
Diaphragm wall frozen construction worker method of the present invention, at first in a distance, diaphragm wall design attitude both sides, the usefulness of freezing of certain density of constructing is holed, and drilling depth should surpass diaphragm wall design maximum degree of depth certain distance; Drilling construction finishes, and frigo is installed in freezing hole, implements artificial Freezing stratum as rapid, promptly provides cold to frigo, makes its Freezing stratum as rapid on every side, and forms the frozen soil wall that reaches designing requirement.After frozen soil wall thickness and average temperature reach designing requirement, under the protection of frozen soil wall, adopt well worker or mechanical means to divide groove section cutting slots, and where necessary the slotted eye wall is carried out supporting; Slotted eye is handled wall section joint on earth and after the acceptance(check), then carries out the casting and constructing of steel concrete diaphragm wall body of wall.
Claims (4)
1. diaphragm wall frozen construction worker method is characterized in that:
Step 1: adopt artificial stratum freezing process to form frozen soil wall;
Step 2: under the protection of formation frozen soil wall, artificial or Mechanical Method construction slotted eye, and where necessary the slotted eye wall is carried out supporting;
Step 3: concreting in the slotted eye that construction is finished, and couple together with adjacent wall section.
2. diaphragm wall frozen construction worker method according to claim 1, it is characterized in that: described artificial stratum freezing process is a distance, the slotted eye outside in the diaphragm wall section of intending construction, freezing of certain density of constructing with boring, in these borings, frigo is installed, provide cold to frigo, make its Freezing stratum as rapid on every side, and form the frozen soil wall (comprise and freeze rock) that reaches designing requirement.
3. diaphragm wall frozen construction worker method according to claim 1 and 2 is characterized in that: described drilling depth should surpass diaphragm wall design maximum degree of depth certain distance.
4. according to claim 1 or 2 or described diaphragm wall frozen construction worker method, it is characterized in that: described concreting is to carry out under the situation that does not have mud and water.
