Abstract
The utility model provides a reverse construction method well that old and new's pipeline was linked up, includes dado, ring beam, bottom plate and access sewage pipe, the ring beam be located dado top, the bottom plate be located the below of dado, access sewage pipe and the first sewage pipe downside that is located the dado and the centre of a circle at the coplanar, its characterized in that, the dado constitute by a plurality of standard dado, standard dado placing from last down one deck. It goes along with sb. To guard him the layer to be equipped with the high pressure jet grouting pile stagnant water on the inboard dado. The bottom plate be equipped with the high compression set spouting pulp -water earth wall of 3.5 meters thicknesses. The utility model discloses beneficial effect 1. The utility model discloses engineering time is short, and is with low costs, 2. The utility model discloses execution conditions are simple, do not need large -scale retaining pile machinery.
Description
Art
The utility model relates to the well that a kind of the old and new's pipeline is linked up.
Background technology
The method adopting newly-built pipeline to connect old well linked up by usual the old and new's pipeline more, but when pipeline construction condition is restricted, when can not be linked into old well, construction is then needed to go along with sb. to guard him layer for excavation, then in going along with sb. to guard him, carry out the construction of new well, often the construction period is long, has high input, and goes along with sb. to guard him layer and old cross pipe-line position is easily revealed.
Summary of the invention
In order to solve the problem, the utility model utilizes high pressure first to spray stake as retaining design that is peripheral and bottom, plays support and sealing effect, constructs simultaneously and do not need large-scale fender post machinery to march into the arena; Utilize contrary sequence method walling crib as going along with sb. to guard him layer, it is safe for excavating downwards for layering; Utilize contrary sequence method walling crib as inner side borehole wall template, save walling crib external mold and install.
The utility model solves the technical scheme that its technical problem adopts
The contrary sequence method well that the old and new's pipeline is linked up, comprise retaining wall, ring beam, base plate, the first soil pipe and access soil pipe, described ring beam is positioned at above retaining wall; Described base plate is positioned at the below of retaining wall; Described access soil pipe and the first soil pipe be positioned at the downside of retaining wall and the center of circle at same plane, described retaining wall is made up of several standard retaining walls, the placement in layer from top to bottom of described standard retaining wall.High-pressure rotary jet grouting pile sealing is housed on inside retaining wall and goes along with sb. to guard him layer.Described base plate is provided with 3.5 meters of thick high compression set preventing slurry injection cement soil walls.
The utility model beneficial effect
1. the utility model engineering time is short, and cost is low;
2. the utility model execution conditions are simple, do not need large-scale fender post machinery.

Detailed description of the invention
As Figure 1-Figure 4,7 is design ground, and 8 is existing ground, the contrary sequence method well that a kind of the old and new's pipeline is linked up, and comprise retaining wall, ring beam 1, base plate 3, first soil pipe 6 and access soil pipe 5, described ring beam 1 is positioned at above retaining wall; Described base plate 3 is positioned at the below of retaining wall; Described access soil pipe 5 and the first soil pipe 6 be positioned at the downside of retaining wall and the center of circle at same plane, it is characterized in that, described retaining wall is made up of several standard retaining walls 2, the placement in layer from top to bottom of described standard retaining wall 2.High-pressure rotary jet grouting pile sealing is housed on inside retaining wall and goes along with sb. to guard him layer.Described base plate 2 is provided with 3.5 meters of thick high compression set preventing slurry injection water 9 earth walls.
The method that contrary sequence method well adopts high pressure jet grouting 9 (churning and determine spray) to combine with contrary sequence method is as foundation pit system.Wherein all adopt below existing steel bar concrete soil pipe and well body base plate and determine absolute altitude at the bottom of pressure spray process construction to design stake, other position soil body all adopts churning construction technology to designing absolute altitude at the bottom of stake.
Whole contrary sequence method well utilize peripheral two-layer D600450 high-pressure rotary jet grouting pile make one columnar structured, then in layer carry out contrary sequence method structure construction from top to bottom going along with sb. to guard him in layer.Each Rotating fields is one circle shoring structure inherently.This equals in whole digging process, have inside and outside two-layer supporting and protection structure.Skin is that 1.05 meters of thick high-pressure rotary jet grouting pile sealings go along with sb. to guard him layer, and internal layer is that layer gone along with sb. to guard him by the steel concrete of thick 550 millimeters.And the high compression set preventing slurry injection cement soil wall that bottom 3.5 meters is thick, effectively can prevent bottom piping and protuberance.This is favourable to the stable of total, is favourable to preventing outside soil deformation.
Claims (3)
1. a contrary sequence method well for the old and new's pipeline communication, comprise retaining wall, ring beam, base plate, the first soil pipe and access soil pipe, described ring beam is positioned at above retaining wall; Described base plate is positioned at the below of retaining wall; Described access soil pipe and the first soil pipe be positioned at the downside of retaining wall and the center of circle at same plane, it is characterized in that, described retaining wall is made up of several standard retaining walls, the placement in layer from top to bottom of described standard retaining wall.
2. the contrary sequence method well of a kind of the old and new's pipeline communication as claimed in claim 1, it is characterized in that, described retaining wall inner surface is equipped with high-pressure rotary jet grouting pile sealing goes along with sb. to guard him layer.
3. the contrary sequence method well of a kind of the old and new's pipeline communication as claimed in claim 1, it is characterized in that, described base plate is provided with 3.5 meters of thick high compression set preventing slurry injection cement soil walls.
