Description
[technical field]
The utility model relates to a kind of caisson structures, in particular to a kind of work well construction of jacking construction.
[background technique]
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 at mostly on the main line road of cities and towns, is compared with corresponding cutting sunken tube method with shield construction, push pipe
Construction has apparent superiority, and this method does not need to excavate ground notch, but must open at the both ends of laid underground piping
Several active wells are dug, active well is divided into jacking active well and received well again, 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 current to construction section traffic to cause large effect, and pollutes week
The environment on side has seriously affected the normal life of neighbouring resident.
[utility model content]
The main purpose of the utility model is to provide a kind of jacking construction active wells, overcome existing cast in situs active well
Feature long in time limit provides the push pipe work that a kind of design is reasonable, globality is strong, stability is good, structure is simple, improves construction efficiency
Influence when making well, and reducing construction to close to buildings, it is 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 utility model is taken are as follows:
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 blade foot with tyre 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 arranged 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 successively set under bottom plate.
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 blade foot carries out feather plucking processing.
Compared with prior art, the utility model has the beneficial effects that active well ontology described in (1) is using upper and lower uniform thickness
Stalk type, the structure of the type can preferably constrain the borehole wall, and easily controllable vertical subsidence is smaller to range of disturbance around, and mould
Plate can repeatedly use.
(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 facilitates and underground gallery, trench, pipeline, water inlet window in the beneficial effect (2) described in
Equal holes are attached.
(4) the active well body bottom portion described in is equipped with bottom plate and is placed in groove, connect back cover bottom plate more preferably 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 beneficial effect (4) insole board 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
It sets and then enhances the overall stability of retaining wall compared with flat-bottom structure.
(6) active well described in is equipped with gutter and sump, facilitates 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 the pollution for reducing 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, guarantee with surrounding soil
The quality of active well.

Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the B-B sectional view of Fig. 1.
[specific embodiment]
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figure 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 has 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 blade foot 7 with tyre 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
