Description
【Technical field】
The present invention relates to a kind of caisson structures, in particular to a kind of work well construction of jacking construction.
【Background technology】
Pipe-jacking project is a kind of construction method of the embedded underground utilities of modernization, using the municipal buried pipe of jacking construction
Net engineering is located on the main line road of cities and towns mostly, is compared with shield construction with corresponding cutting sunken tube method, push pipe
Construction has apparent superiority, and this method need not excavate ground notch, but must be opened at the both ends of laid underground piping
Dig several active wells, active well is divided into as jacking active well and received well, and wherein reinforced concrete rectangular active well is more normal
See, current active well generally uses excavation pit, live assembling reinforcement, formwork supporting plate casting concrete, the construction then backfilled
Method, the active well site operation duration is longer, necessarily causes large effect to construction section traffic passage, and pollute week
The environment on side has seriously affected the normal life of neighbouring resident.
【Invention content】
The main purpose of the present invention is to provide a kind of jacking construction active wells, overcome the existing cast in situs active well duration
Long feature, provides that a kind of reasonable design, globality is strong, stability is good, push pipe work simple in structure, improving construction efficiency
Well, and influence when reducing construction to close to buildings, it is highly practical, it is easy to promote the use of under the conditions of identical geology.
To achieve the above object, the technical solution that the present invention takes is：
A kind of jacking construction active well, it includes ontology, gutter is arranged in the surrounding of ontology, reserved opening is arranged in side wall
With jacking hole, and haunch is set in inside right angle, borehole wall lower end is arranged to the cutting shoe with tread, and body bottom portion is provided with bottom
Plate, and bottom plate is placed in the groove of its neighbouring borehole wall, and sump is set on well inner bottom plating, and bottom plate is set towards sump direction
There is certain slope, and back cover and the bottom of a pan are set under bottom plate successively.
Further, the sump length and width, deep size are respectively 2.0m, 0.8m, 0.6m.
Further, the reserved opening and jacking dimension of opening are 1200mm*1200mm.
Further, the active well is to pour the reinforced concrete structure for building up an entirety.
Further, the cutting shoe carries out feather plucking processing.
Compared with prior art, beneficial effects of the present invention：(1) the active well ontology described in uses the stalk of upper and lower uniform thickness
The structure of type, the type can preferably constrain the borehole wall, and easily controllable vertical subsidence is smaller to range of disturbance around, and template energy
It repeatedly uses.
(2) the active well body plane shape described in is rectangle, effectively increases the utilization rate in open caisson space and convenient for pre-
The setting of box out mouth and jacking hole, while four corners of inner wall are equipped with haunch, improve the integrally-built intensity of open caisson.
(3) setting of reserved opening contributes to and underground gallery, trench, pipeline, water inlet window in the advantageous effect (2) described in
Equal holes are attached.
(4) the active well body bottom portion described in is placed in equipped with bottom plate in groove, and back cover bottom plate is made more preferably to be connect with the borehole wall,
And play the role of effective waterproof while enhancing structure globality.
(5) back cover and the bottom of a pan are set gradually below advantageous effect (4) bottom plate described in, compared with not back cover open caisson,
The load that this kind of structure foundation unit area is born is smaller so that it is relatively fewer to stop the heavy rear settling amount of punching；And the bottom of a pan is set
Set the overall stability that retaining wall is then enhanced compared with flat-bottom structure.
(6) active well described in is equipped with gutter and sump, contributes to water flooding within the scope of open caisson in the construction process
Drainage has been effectively ensured the stabilization of the construction period soil body and the safety of construction, has saved working hour and manpower, it will be apparent that improved work
Make efficiency, and reduces the pollution of site environment and the influence caused by traffic, living environment.
(7) active well ontology described in is that cast in situs is compared with assembled, this kind of construction method as a whole,
Have the advantages that the big good rigidity of intensity, and excavated volume is small in the work progress of open caisson, contacts closely, ensure with surrounding soil
The quality of active well.

Fig. 1 is the floor map of invention；
Fig. 2 is the A-A sectional views of Fig. 1；
Fig. 3 is the B-B sectional views of Fig. 1.
【Specific implementation mode】
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
As shown in Figs. 1-3, a kind of jacking construction active well, it includes ontology 1, and the surrounding of ontology 1 is provided with gutter
2, and a concrete road surface 12 is set around gutter 2, and have a slope 13 between the road surface and ground, 1 side wall of main body
Reserved opening 5 and jacking hole 6 are set, and haunch 8 is set in inside right angle, borehole wall lower end is arranged to the cutting shoe 7 with tread,
1 bottom of ontology is provided with bottom plate 9, and bottom plate 9 is placed in the groove 4 of its neighbouring borehole wall, and sump is arranged on well inner bottom plating 9
3, and bottom plate 9 is equipped with certain slope, specially 0.5% gradient towards sump direction, and back cover 10 is set under bottom plate successively
With the bottom of a pan 11.
The sump size is 2.0mx0.8mx0.6m (long x wide x is deep), and deep ensure that locally is dug within the scope of sump
Back cover thickness and back cover is laid with c25 concrete, thickness 0.7m, the lower part the bottom of a pan are filled with block stone, and bosom reaches 0.5m.
The reserved opening and jacking dimension of opening is all 1200mmx 1200mm, and the setting of reserved opening is convenient for and ground
Lower gallery, trench, pipeline, the water inlet connections such as window, and the setting at jacking hole is then convenient for tool pipe or development machine from active well
Interior shifted onto in received well always across soil layer is sling.
Active well ontology is reinforced concrete structure, and entering well and going out the reserved opening of well should be blocked up before sinking temporarily
Plug, it is that the reinforcing bar of 200mm is reinforced, and cutting shoe should also carry out feather plucking processing that a diameter of 8mm, spacing, which is used in combination, and open caisson is being constructed
Well-points dewatering is used in the process and is enclosed in well does water-level observation.
The active well of the present invention pours and builds up an entirety, with fabricated active well compared with intensity greatly, good rigidity, with excavation
The cast-in-place active well of foundation pit is small compared to excavated volume, and the close stabilization for ensureing the construction period soil body, construction peace are contacted with surrounding soil
Entirely, efficient, reduce the pollution site environment and the influence caused by traffic, living environment.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should be included within the scope of the present invention.
