Abstract
The present invention relates to a freezer arrangement method for accelerating the speed of freezing local area rock-soil for cutting rockshaft with large section, and said method includes the following steps: drilling and cutting freezing hole around entrance for excavating channel, placing freezer formed from steel pipe and plastic pipe in the freezing hole, non-linear arranging or linear and non-linear alternatively arranging the freezer placed in the freezing hole along the excavated channel deep-portion, so that it raises the after-efficiency of freezer, and can accelerate the speed of freezing target area rock-soil, and can reduce freezing time and cost.
Description
One, technical field
The present invention relates to a kind of acceleration and freeze the frigo method for arranging of regional area ground, be used for the artificial frozen construction worker of geotechnical engineering method, be particularly useful in deep topsoil, digging vertical shaft pit shaft with large diameter, also be applicable to freezing process and dig inclined shaft, footrill (or tunnel) and foundation ditch with freezing process.
Two, background technology
In the geotechnical engineering construction freezing method, the frozen soils structure that manually freezes to form will satisfy the requirement of water proof and the part or all of water and soil pressure of opposing.Along with the expansion of excavated section size and the increase of cutting depth, water shutoff problem and the big problem of work plane distortion of excavating regional bottom (or the place ahead) become increasingly conspicuous.The main way that addresses these problems is thickness and the intensity that increases these target area frozen soil, even freezes real target area.In existing frigo method for arranging, the layout axis of frigo all is designed to vertical curve, horizontal linear or angled straight lines, and the target territory that requires the construction axis not depart from regulation.Though the method for arranging of this frigo can be finished the task of Frozen Rock and Soil, but its time of freezing is longer, and the speed of excavation construction is very fast at present, though thereby top has reached the excavation condition, but also do not have when being excavated to the deep to form frozen soil curtain (or frozen soil curtain of back cover), influenced the construction period greatly and caused unnecessary economic loss with sufficient intensity and rigidity.
Three, technology contents
1. goal of the invention
Problem in view of prior art exists the purpose of this invention is to provide the frigo method for arranging that the regional area ground is freezed in a kind of acceleration, and it can shorten freeze-off time, reduces cost, and guarantees excavation construction safety.
2. technical scheme
The present invention quickens to freeze the frigo method for arranging of regional area ground, Drilling freezing hole around the ground settlement and tunnel inlet, and the frigo that setting is made up of steel pipe and plastic pipe in freezing hole, describedly be put in down frigo in the freezing hole, or to have a frigo at least be that non-linear is arranged along excavation passage deep non-linear layout or linear and non-linear arranged crosswise.
3. technique effect
The present invention quickens to freeze the frigo method for arranging of regional area ground, be best suited in deep topsoil and dig vertical shaft pit shaft with large diameter with freezing process, compare with original linear frigo method for arranging, improved the later stage efficient of frigo, reduced the quantity of freezing hole; Accelerate the freezing speed of target area ground, can save freeze-off time and expense; The shape of frozen soil wall and position can change according to engineering specifications and geological conditions; Solved driving and masonry construction speed fast with the ground freezing speed contradiction between slowly.

Five, the specific embodiment
The invention will be further described below in conjunction with the embodiment in the accompanying drawing:
The present invention quickens to freeze the frigo method for arranging of regional area ground, Drilling freezing hole around ground settlement and tunnel inlet 1, and the frigo 2 that setting is made up of steel pipe and plastic pipe in freezing hole, describedly be put in down frigo 2 in the freezing hole, or to have 1 frigo at least be that non-linear is arranged along excavation passage deep non-linear layout or linear and non-linear arranged crosswise.
Embodiment one: as shown in Figure 1, the frigo 2 that linear and non-linear are arranged is spaced, partly (or at interval) frigo 2 is arranged to excavation passage inside bend in the excavation depths, substantially be into broken line shape, be that frigo 2 tops are for vertically arranging, the bottom is to the inboard skew of excavation passage certain distance, as shown in Figure 2; The axis of remaining part frigo 2 still is a rectilinear form, and promptly frigo 2 is vertical layout from top to bottom, as shown in Figure 3.This kind frigo method for arranging can quicken to excavate freezing of channel center's ground, can create conditions for excavating in advance.
Embodiment two: as shown in Figure 4, the frigo 2 that linear and non-linear are arranged is spaced, partly (or at interval) frigo 2 is arranged to excavation passage outside curve in the excavation depths, substantially be into broken line shape, be that frigo 2 tops are for vertically arranging, the bottom is to excavation passage outside skew certain distance, as shown in Figure 5; The axis of remaining part frigo 2 still is a rectilinear form, and promptly frigo 2 is vertical layout from top to bottom, as shown in Figure 6.This kind frigo method for arranging can improve frigo in the efficient in later stage, under the situation that does not increase freezing hole quantity, obtains frozen soil wall thicker and that average temperature is lower in the bottom.
Embodiment three: as shown in Figure 7, freeze all device 2 is arranged to excavation passage inside bend in the excavation depths, substantially be into broken line shape, frigo 2 is arranged for horizontal linear to excavating in the direction setting distance range from the excavation inlet, frigo 2 remainders are to the inboard skew of excavation passage certain distance, as shown in Figure 8.This kind frigo method for arranging can guarantee to be easy to form a Frozen Rock and Soil pad near the frigo afterbody, to prevent that building work plane the place ahead in pick water burst, prominent mud accident occur.
Claims (1)
1. quicken to freeze the frigo method for arranging of regional area ground, at ground settlement and tunnel inlet (1) Drilling freezing hole on every side, and the frigo (2) that setting is made up of steel pipe and plastic pipe in freezing hole, it is characterized in that: describedly be put in down frigo (2) in the freezing hole, or to have a frigo at least be that non-linear is arranged along excavation passage deep non-linear layout or linear and non-linear arranged crosswise.
