Abstract
The invention relates to a construction method of an underground continuous wall below an underground pipeline in urban construction. The method comprises the following steps: (1) a trenching machine is used for grapping the soil mass at one side of an underground pipe culvert under the matching action of a circular hydraulic grab, and a deep groove is formed; (2) a guide rail box is placed in the deep groove; (3) a special machine head is hoisted in the groove and is in tongued and grooved connection with the guide rail box; (4) the special machine head performs milling to the soil mass below the pipe culvert from the top down; (5) the transverse milling is gradually formed, a height mark is designed for the underground continuous wall; (6) the special machine head and the guide rail box are pulled out; (7) the soil mass at the other side of the pipe culvert is grabbed by using the trenching machine; (8) the soil mass in the entire pipe culvert area is completely cleaned; (9) a reinforcement cage positioned at the bottom of the pipe culvert is hoisted and placed at the left side and the right side and then is translated below the pipe culvert; (10) the reinforcement cage is hoisted and placed in the rest groove section at both sides; and (11) the concrete pouring is carried out. The invention has the advantages that the underground pipeline is not required to be moved during the construction of the urban underground continuous wall and the traffic is not blocked.
Description
Technical field
The present invention relates to a kind of construction method of underground continuous wall, particularly a kind of in urban construction the construction method of underground continuous wall under underground utilities.
Background technology
At present along with socioeconomic fast development; Ground and space, upper strata are in short supply day by day, and therefore present increasing underground building is dropped into and built, as in order to enlarge the subway of city for the supporting capacity of flow of personnel; Underground express way for quick traffic also has various underground stores.Owing to normally in ripe city, carry out infrastructure now, therefore must bring many problems, one of them is exactly to be clouded in underground various pipelines; Like power cable, communication cable, Gas Pipe, water pipe, soil pipe etc.; When carrying out underground construction,, offer the road surface of an expansion earlier in the roadside, road usually in order to ensure the safety and the maintenance running status of underground existing pipeline; Underground various pipelines are displaced to temporarily the road surface of expansion; Vacating the trenching construction that the original position place carries out diaphragm wall then, wait construction of diaphragm wall to finish after, again underground utilities are retracted original position again.Because the engineering quantity and the difficulty of underground construction are very big; Therefore need consumption great amount of manpower and material resources and time to turn over the work of handing over; Also brought simultaneously and had a strong impact on the unimpeded of original road; And along with the density of urban architecture increases, it is not have condition can temporarily arrange the resettlement of underground pipe culvert local that a lot of zones are arranged.Therefore demand urgently inventing and a kind ofly can not move underground utilities directly carry out construction of diaphragm wall in the original place technology.
Summary of the invention
The objective of the invention is to solve in the prior art, when carrying out construction of diaphragm wall, need move the existing the problems referred to above of the underground utilities that passed through, provide a kind of in urban construction the construction method of underground continuous wall under underground utilities.The present invention design a kind of in urban construction the construction method of underground continuous wall under underground utilities, it is characterized in that forming by the following step:
(1) joins circular hydraulic grab with groover and grab the soil body that removes underground pipe culvert one side, and form a deep trouth;
(2) in deep trouth, be sidelong and put the guide rail case away from one of pipe culvert;
(3) special-purpose head is hung in the groove, adopt tongue and groove to be connected with the guide rail case;
(4) special-purpose head is parked in the in-milling depth location of reserving in advance, launches the milling bar of special-purpose head, the soil body under the pipe culvert is carried out milling from bottom to top;
(5) special-purpose head forms in-milling gradually, by special-purpose head the earth under the pipe culvert is carried out milling from top to bottom then, to the diaphragm wall design elevation;
(6) pull out special-purpose head, guide rail case;
(7) grab the soil body with groover except that the pipe culvert opposite side;
(8) soil body complete liquidation in the whole pipe culvert zone is clean, and cell wall is brushed wall cleaning and clear bottom reason;
(9) hang the reinforcing cage that is positioned at the pipe culvert bottom in left and right sides, move to the pipe culvert below after hanging;
(10) install reinforcing cage in the groove section of both sides remainder;
(11) concreting.
Advantage of the present invention is in the construction of continuous concrete wall of city, need not move underground utilities, saves great amount of manpower and material resources and has save turning over of road traffic and handed over trouble.

Accompanying drawing 12 is a casting concrete construction sketch map of the present invention.
Below in conjunction with accompanying drawing and instance the present invention is elaborated.
The specific embodiment
At first join circular hydraulic grab 1 with groover and grab the soil body that removes underground pipe culvert 2 one sides, and form a deep trouth in underground pipe culvert one side; Side away from pipe culvert 2 in deep trouth is vertically placed guide rail case 3; Special-purpose head 4 is hung in the groove, adopt tongue and groove to be connected with the guide rail case; Special-purpose head is parked in the in-milling depth location of reserving in advance, launches the milling bar of special-purpose head, the soil body under the pipe culvert 2 is carried out milling from bottom to top; Special-purpose head forms in-milling gradually, carries out milling from top to bottom by the earth under 4 pairs of pipe culverts of special-purpose head then, to the diaphragm wall design elevation; Pull out special-purpose head 4, guide rail case 3; Grab the soil body with groover then except that pipe culvert 2 opposite sides; After treating all to excavate earth, the soil body in whole pipe culvert 2 zones is cleaned out, cell wall is brushed wall cleaning and clear bottom reason.Because underground pipe culvert 2 is positioned at the center in whole space, therefore with reinforcing cage four making in 5 fens, hang the reinforcing cage 5 that is positioned at pipe culvert 2 bottoms from the right and left, move to the pipe culvert below after hanging again; Hang other two reinforcing cages 5 again, carry out concrete building at last.
