Description
Technical field
The invention belongs to construction engineering technical fields, are related to one kind and secretly checking room equipment opening/manhole and its construction method.
Background technology
The country mainly passes through in solving downtown area shallow buried covered excavation and secretly checking room equipment opening/manhole construction at present
Steel suspension bridge, night open caisson construction are set up daytime to secretly checking room vault or side wall.
Open caisson construction equipment opening/manhole has the disadvantage that：
（1）It is stringent to construction progress control, once night can not construct open caisson tube coupling to below ground, road will be influenced daytime
It is current；
（2）Open caisson tube coupling and tunnel structure contact surface difficulty of construction are big, waterproof is bonded difficulty, later stage underground water easily from contact surface into
Enter inspection chamber；
（3）The backfill of open caisson tube coupling back is difficult, and the later stage easily settles；
（4）Construction is influenced by present situation underground utilities, and underground utilities are met in construction to be avoided, and large area excavation is needed to change shifting pipeline
Or backfill changes shifting design position, again the shortcomings of excavation construction.
Secretly folding is chiefly used in shallow-depth-excavation tunnel construction in tunnel, and manually digging hole fado is constructed for bridge pier, and technology maturation is applied
Work process flexible, application cost are low, construction efficiency is high, are widely used to shallow-depth-excavation tunnel construction and bridge pier is constructed, but
It secretly checks in room equipment opening, artificial construction and there is no application.
With the close scheme of the present invention be Beijing blueprint Engineering Co., Ltd " heating pipeline secretly do the structure design of cell with
Construction " technical solution.The program mainly elaborate downtown area heating power cell do not have it is bright open execution conditions, it is disconnected by tunnel
Face gradual change to meet the device space requirement the construction method for secretly checking room.It is not directed to and secretly checks room equipment opening/manhole
Specific practice.
Invention content
The purpose of the present invention is the one kind in view of the above technical problems, provided secretly checks room equipment opening/manhole and its applies
Work method secretly rolls over construction using subterranean tunnel, is not take up earth's surface place, adaptable advantage strong, construction is convenient；Using people
Work borehole method is constructed, and constructing, it is small to be influenced by underground utilities, and the construction time is short, and backfill compactness is easy to control, and cutting depth is adjustable
Section, emergency processing is convenient, has the advantages that low engineering cost, construction safety degree are high.
Technical scheme of the present invention
In order to solve the above technical problems, one kind provided by the invention secretly checks room equipment opening/manhole, specifically include laterally logical
Road and vertical passageway, the interconnection are arranged in the side for secretly checking room, are vertically arranged with the secretly room of checking；It is described perpendicular

Structure is overlapped by manually digging hole method and interconnection；The just lining structure is recycled by several reinforced concrete core-tubes to be overlapped, with
The tunnel for connecting horizontal pipeline just serves as a contrast and construction ground, two lining structure are arranged in the inside of first lining structure.
Further, the reinforced concrete core-tube of the just lining structure uses steel form, adjacent segments overlap joint to be not less than 50mm,
To ensure the integral strength of just lining structure, it is ensured that engineering construction quality.
Further, the reinforcing bar in the reinforced concrete core-tube includes circumferential reinforcement and longitudinal reinforcement, the circumferential direction steel
Muscle welds to form steel reinforcement cage with longitudinal reinforcement, and the longitudinal reinforcement stretches into adjacent reinforced concrete core-tube.
Further, the reinforcing bar of the reinforced concrete core-tube is connected by the arch reinforcing bar on L-type steel muscle and interconnection
It connects.
Further, two lining structure reinforcing bar of the interconnection and the reinforcing bar of vertical passageway bind pour simultaneously, and reinforcing bar connects
It meets place and arc reinforcing beam is set along tunnel lateral direction, along the longitudinally disposed crossbeam in tunnel, be arranged along hole and radiate reinforcing rib, above and below hole
Modal circumferential stiffening rib is set.
Meanwhile it present invention also provides a kind of construction method secretly checking room equipment opening/manhole, specifically including following
Step：
S1 is arranged ingate secretly checking the following stalk end in room side wall arch, excavates interconnection to designated position；
S2, hand excavation vertical passageway simultaneously pour breast wall concrete with template, and cycle construction to tunnel just serves as a contrast vault；
S3 abolishes concrete and connects reinforcing bar, integrally performs the waterproof of vertical passageway and interconnection；
S4 binds two lined steel muscle of vertical passageway and interconnection and pours.
Advantageous effect of the present invention：
One kind provided by the invention secretly checks room equipment opening/manhole and its construction method, reasonable for structure, has following technology
Effect：
（1）By laterally opening interconnection to both sides of the road suitable position in the secretly room of checking, it is not limited to secretly check on room
Side, can avoid the underground utilities of construction site, have the advantages that construction is flexible；
（2）The application uses manually digging hole, and supporting is deep-controlled flexibly, does not influence walk on daytime, avoids site operation
Influence to road；
（3）Just lining panelling construction technique is similar with tunnel for manually digging hole method panelling construction technique, and construction to contact surface can pass through chisel
Go out the connection of tunnel structure reinforcement welding, bolt-spary supports is same entirety, and construction technology is simple, good integrity；
（4）Since contact surface is same entirety, waterproof can be performed simultaneously with tunnel, ensure waterproof construction globality, pour simultaneously
Leakage scenarios will not occur for two layers of liner structure, contact surface；
（5）For manually digging hole method retaining wall by anchor spraying concrete supporting, back is not likely to produce hole region, and can reserve back slip casting
Pipe, timely slip casting backfill is closely knit, is not susceptible to road settlement.
