Abstract
The utility model discloses a construction device for rigid joints of underground continuous walls a horseshoe fore shaft pipe which can be lifted and arranged in a molding groove soil pit and two joint boxes which are abutted tightly and are arranged at two end surfaces of the opening of fore shaft pipe. The other side of the joint box can be attached tightly a sealing head steel plate, the sealing head steel plate and a rigid joint steel plate which can be embedded into the opening of the fore shaft pipe are welded and molded in a crisscross mode. The construction device for rigid joints of underground continuous walls can be used for seepage proof curtains of harbors, wharves, docks and dams, and construction of underground continuous walls of aspects of underground bases, etc. of city high buildings, underground tunnels, coal mine upright shaft, tunnels cross rivers, push pipe working shafts, industrial buildings, large scale equipment.
Description
The utility model relates to a kind of construction technology equipment that is used to build the one diaphragm wall vertical joint place's rigid joint of deep foundation construction technique.
Diaphragm wall is the new deep foundation construction technology that China's developed recently gets up.Middle nineteen seventies begins, be applied to harbour, harbour, dock, dam seepage proof curtain by increasingly extensive, and aspects such as urban skyscraper, underground railway, coal mine shaft, cross-river tunnel, upper pipe working well, industrial structure or main equipment underground foundation.Because the diaphragm wall vertical joint of present domestic construction adopts the flexible joint of no horizontal connector mostly, and because tension, shearing resistance and the impervious ability of flexible joint are all lower, cause the integrated carrying ability of the diaphragm wall that builds up low, can not adapt to the requirement of large foundation construction development.
The purpose of this utility model is to overcome the shortcoming in the above-mentioned construction of diaphragm wall, provides the complete rigid joint of a cover to lay construction technology equipment.This equipment comprises: the shape of a hoof fore shaft pipe (5) that can hang in the grooving heatable adobe sleeping platform, and two slide type joint casees (2) of placing near the two ends of fore shaft tube opening, the another side of joint case can be adjacent to end socket steel plate (1), and end socket steel plate and rigid joint steel plate (3) the across welding fabrication that can embed in fore shaft pipe (5) opening.
Its solution is: change original flexible joint on the face uniform pertusate rigidity plate joint, also be welded with some little plate washers on its top, horizontal side, shape of a hoof fore shaft pipe by being close to groove face, two slide type joint casees and on the top power effect of gas tube, make to be welded into criss-cross end socket steel plate and correctly to be cast in the concrete with the joint steel plate is vertical.Thereby improved tension, shearing resistance and the impervious ability at diaphragm wall vertical joint place greatly, created good condition for applying the diaphragm wall novel technique in the building deep foundation engineering.
Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is elaborated: wherein
Figure one is a shape of a hoof fore shaft pipe profile schematic diagram,
Figure two is a shape of a hoof fore shaft pipe internal construction schematic diagram,
Figure three is rigid joint construction process equipment general assembly schematic configuration diagram,
Figure four is ported sub steel plate and the end socket steel plate and the joint case combination schematic diagram of cross butt joint.
Referring to figure one, figure two, the outside of shape of a hoof fore shaft pipe (5) by metal sheet for example steel plate be welded, be enclosed shape, the centre is provided with opening (7), so that the time put into joint steel plate (3) with the welding of end socket steel plate (1) across in construction.Also being welded with on shape of a hoof fore shaft pipe (5) can be for two hanger (8 and 8) of lifting usefulness.The inside of shape of a hoof fore shaft pipe is by many shaped steel, and for example group such as angle steel, channel-section steel frame supports, and support place can link to each other by connection means (as welding, riveted joint), to increase the support force of fore shaft pipe integral body.The profile at the rear portion of shape of a hoof fore shaft pipe (5) (establish opening part be anterior) depends on that the shape that supporting grooving machinery excavates grooving decides, and is generally circular arc.
Referring to figure three, figure four, wherein slide type joint case (2) is welded by shaped steel (as channel-section steel).About be two channel-section steels (9 and 9), two ends connect into integral body with the round steel post, middle support with shaped steel formula steel plate, gas tube (6) is equipped with in its outside, gas tube (6) can be used rubber tube, or brocade is moulded pipe.After gas tube (6) inflation, can produce roof pressure power to the end socket steel plate.Use two slide type joint casees (2) can accomplish that this roof pressure force rate is balanced simultaneously.Can paste with plastic plate to form slide plate, so that hang out later on this external joint case (2) and the plane that fore shaft pipe (5) or end socket steel plate (1) contact.
During construction, and scrape out slotted eye with continuous wall trench underground machineries such as guide plate grab bucket and bull brills, on the ground with after cross welding fabrication and the calibrated distortion, promptly with steel class securing member it is combined joint steel plate (3) and end socket steel plate (1) with two slide type joint casees (2).For guaranteeing construction quality, should hang into groove previous crops air test, the blowing pressure maintains about 3 kilograms 1 square centimeter, observes half an hour, to guarantee the gas tube (6) that is contained in slide type joint case two outsides good sealing property is arranged.
Formally hanging this construction when using process equipment, should hang shape of a hoof fore shaft pipe (5) earlier, require the rear portion of fore shaft pipe to be close to cell wall, the bottom will be inserted into bottom land always.And then hang the cross steel plate and the slide type joint case composite member (referring to figure four) of combination forming in advance, make it be placed into groove.Be install reinforcing cage subsequently, the conventional operation of fluid concretes such as underwater concrete conduit is installed.In concrete pouring, the gas tube pressurization produces roof pressure power, and rigid joint construction just in place finishes.
When this equipment will take out, after should treating gas tube venting decompression earlier and removing external distribution pipeline, two slide type joint casees and shape of a hoof fore shaft pipe etc. are pulled out respectively hang out again.
The surface of rigid joint steel plate is evenly equipped with a plurality of holes, and in the welding of the horizontal side end face of joint steel plate little plate washer, make concrete pit section after the cast strengthen the ability of tension, shearing resistance, thereby improved the bearing capacity of ground continuous wall base construction works effectively, opened up wide prospect for enlarging the Application of Diaphragm wall Construction Techology and the scope of application.
