Specific embodiment
Below in conjunction with the accompanying drawings and the preferred embodiment specific embodiment that the present invention will be described in detail.As shown in Fig. 1 and Fig. 2,
A kind of assembled underground pipe gallery, including left prefabricated board 1, right prefabricated board 2, bottom plate 3 and top plate 4, the left prefabricated board and the right side are pre-
The top one side of making sheet is respectively equipped with top bar 5, and the lower part one side of the left prefabricated board and right prefabricated board, which is respectively equipped with, gets out of a predicament or an embarrassing situation
6, the temporary support beam 7 with the two activity cooperation, the length of temporary support beam are equipped between the left prefabricated board and right prefabricated board
Identical with the length of bottom plate and top plate, width is narrow, primarily serves the effect of two pieces of prefabricated boards of support.For the ease of adjacent
The both sides of two pieces of prefabricated boards, the left prefabricated board and right prefabricated board are respectively equipped with the snap fastener being mutually matched, and snap fastener is embedded in
Expansion sealing strip.
It is sunk to for the ease of left prefabricated board and right prefabricated board in control ditch, the bottom of the left prefabricated board and right prefabricated board
Cutting shoe 8 is respectively equipped with, the bottom of cutting shoe is plane, and the plane of bottom prevents prefabricated board from unlimitedly sinking.
In order to which bottom plate and left and right prefabricated board is made to fix and more increase securely, the bottom plate and the left prefabricated board and the right side are prefabricated
Reinforcing rib 9 is welded between plate.
The invention also discloses a kind of construction method of assembled underground pipe gallery, Step 1: surface control ditch is constructed：On ground
Two control ditches 10 are opened in face, and the width of the control ditch is more than the width of left prefabricated board and right prefabricated board, the depth of ditch is controlled to be more than
Or the height equal to left and right prefabricated board；Ensure that left and right prefabricated board can be put into control ditch, open control ditch and application may be employed
The special ditching control ditch device of the soft waterproof of deep basal pit applied before people carries out digging control ditch, controls in ditch and pours slurry coat method,
Common excavator can also be used, excavator bucket is narrowed.
Step 2: the prefabricated side wall of underground pipe gallery sinks：Left prefabricated board and right prefabricated board are sequentially placed into control ditch respectively
Two pieces of interior, adjacent left prefabricated board grafting each other, adjacent two pieces of right prefabricated board grafting each other；In order to ensure two pieces it is adjacent pre-
It is sealed between making sheet, adhesive tape may be employed and be sealed.
Step 3: by the top soil removal between left and right prefabricated board, expose top bar, by the both ends of temporary support beam
It is individually positioned in the top bar of left and right prefabricated board；Temporary support beam plays the role of support, prevent left and right prefabricated board due to
The lateral compression power of soil inwardly moves.
Step 4: the soil between left and right prefabricated board is dug out, until digging to the position got out of a predicament or an embarrassing situation；
Step 5: the both ends of bottom plate are individually positioned on the getting out of a predicament or an embarrassing situation of left and right prefabricated board；
Top plate is placed in top bar simultaneously again Step 6: first removing temporary support beam.
Step 7: last backfill.
Preferably, in step 5, bottom plate is prefabricated bottom plate or cast in situs into bottom plate.Cast in situs bottom plate can be more
What is added is secured.
In step 6, the top plate is prefabricated bottom plate or cast in situs into bottom plate.
As shown in figure 3, left and right prefabricated board removes upper and lower step when cast in situs is into bottom plate, in the position of former upper and lower step
It puts and is welded with connection reinforcing bar, connection reinforcing bar is the state being bent upwards when being lowered into control ditch, will after tripping in control ditch is interior
Reinforcing bar is converted into level, and mold pouring molding is made after the connection reinforcing bar on left and right prefabricated board is interconnected by reinforcing bar.
As shown in figure 4, the settlement Control of underground pipe gallery：When the bottom plate of underground pipe gallery is located at the poor soil of Geotechnical Characteristics
During layer, the settlement control of underground pipe gallery is considered as.Following working measure can be used：For deep soil layer, in step 1,
Prefabricated pile is previously charged into control ditch, prefabricated pile is driven into ground for concrete stake or iron cage stake, prefabricated pile by vibration hammer；It is prefabricated
The left and right prefabricated board of support is played the role of in stake, prevents from.In addition, bottom plate sinks in order to prevent, in step 4, mud is dug out
After soil, more prefabricated piles are squeezed on ground, prefabricated pile is driven into ground by vibration hammer.Prefabricated pile plays the work of support baseboard
With.
For deep soil layer, this method can also support baseboard in another way, i.e., in step 4, after digging out soil,
Sandstone is spread on ground, then is earthward punched by the drill steel of quartering hammer, it is broken to enter formation in hole for sandstone behind drill steel disengaging hole
Stone mar utilizes broken stone pile support baseboard.
As shown in figure 5, being improved as the another of the present invention, for the construction environment of shallow soil, in step 4, dig out
After soil, sandstone is spread on ground, more drill steels are welded in the bottom of one block of steel plate, the top of steel plate is connected with quartering hammer, most
With quartering hammer steel plate is driven to output multiple holes on ground afterwards, after steel plate is withdrawn, sandstone enters formation broken stone pile in hole.
The water-proofing treatment measure of prefabricated underground pipe gallery seam：
1st, grouting process can be used on the outside of underground pipe gallery prefabricated pipe section seaming position and strengthen the soil body, control leakage.
2nd, prefabricated pipe section link position is equipped with mother-son mouth, and expansion sealing strip is set in mother-son mouth.
3rd, prepared screw-bolt hole on the inside of the piping lane of prefabricated piping lane side wall seaming position, for the fixation of liner steel plate for sealing water.
4th, prefabricated pipe section seaming position nearby reserves injected hole.It treats to stop on the inside of outside soil body subsidence pressure circle spray reinforcement and piping lane
After water Interal fixation, welding, abutment joint position carries out secondary grouting.
The anti-floating control of underground pipe gallery：Prefabricated underground pipe gallery balances buoyancy force of underground water by dead load.It can be according to calculating
The rationally thickness of definite bottom plate and top plate second pouring last layer, and not less than 200mm.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
