Description

Constitute the diaphram wall of piping lane sidewall

Technical field

The invention belongs to municipal administration underground engineering technical field, be specifically related to a kind of underground constituting city integrated piping lane sidewall Diaphragm wall.

Background technology

China's Municipal public utilities adhere to different unit construction and management separately, owing to building time is the most different, and Urban underground space is not carried out unified planning and comprehensive utilization.Underground pipe network builds the city planting ductwork using tradition direct-burried more Engineering construction mode, mostly various municipal pipelines are directly to be embedded in soil layer by respective system, maintenance inconvenience, are easily damaged, The ability of securing an adequate supply is often subject to interference.Owing to the depth of burying of various pipelines differs, easily causing conflict, urban road is frequent Destroyed.Road surface is repeatedly excavated and is caused route denial, traffic jam, road surface patch pile patch.Along with urban development, buried pipe Line is the most complicated, the most deep-rooted, is formed " the problem that cooks noodle ".Subway work is also because of relocation of services or temporary shift Increasing construction cost even causes resident to be discontented with.Pipe network facilities increases or maintenance, and the building site of urban construction also can be found everywhere, all As coal gas changes natural gas, lays communications optical cable, buries cable power transmission, water supply network repairing, gas piping repairing etc. underground.A lot of cities Road surface the same constantly excavates also like slide fastener, fills.The pipe network accidents institute that the whole nation is caused because of construction every year according to incompletely statistics The direct economic loss caused reaches 5,000,000,000 yuan, and indirect economic loss reaches 40,000,000,000 yuan more than.

Underground pipe gallery is also known as " common trench ", various pipeline collection such as electric power, communication, combustion gas, water supply, draining, heating power In one, the underground space at urban road builds an intensive tunnel.Underground pipe gallery, makes space utilization more fill Point, compact, economical, also allow for maintenance, more will not be because overhauling old pipe, the new pipe of the row of applying and continuous excavated pavement.State Council in 2014 General office issues " instruction about strengthening City Buried Pipeline implementation management " (Office of the State Council sends out (2014) No. 27), clearly proposes Move forward steadily Urban Underground pipe gallery construction, carry out underground pipe gallery pilot project 36 big and medium-sized cities.Multi-form Underground pipe gallery, its form of fracture, accommodate pipeline kind, cost, keep in repair and manage the most different.At present Beijing, deep The cities such as ditch between fields, Hangzhou, Ningbo have been built up or positive construction parts underground pipe gallery.

Existing underground pipe gallery mainly uses two ways: the first is cast-type piping lane, is first treating excavation pit Both sides set foundation pit enclosure, then the excavation pit earthwork, and finally the both sides in foundation ditch carry out poured in place concrete and form piping lane, Finally piping lane is covered by backfill soil.Foundation pit enclosure typically uses firm sheet pile or cast-in-situ bored pile to connect and is formed, but because of its intensity And water resistance is poor, and lack suitably in order to the junction point preferably fixed with piping lane base plate, roof, it is impossible to as piping lane A part for sidewall, whole piping lane main body must all in the foundation ditch gone along with sb. to guard him cast in situs separately (reinforcing bar is rolled, template is propped up Vertical, concrete casting and maintenance etc.), therefore, this cast in situs formula piping lane exist long construction period, construction costs costly, It is not easy to the shortcoming such as application of advanced construction technology.The second is that underground pipe gallery is contained in Integral prefabricated type side, and it exists volume and weight Amount is big, brings manufacture equipment Requirement height, lifting difficulty, freight volume big, the shortcomings such as freight is high, and is susceptible to piping lane locally Sedimentation and drainage.Also have one be use diaphram wall as foundation pit enclosure, although this diaphram wall is in theory As the sidewall of piping lane, but during practice of construction, can lack suitably in order to the company preferably fixed with piping lane base plate, roof Contact and stress point, the therefore inconvenient top carrying out cast formation piping lane between adjacent two diaphragm walls and bottom, additionally also The technical problems such as the connection that needs to consider between diaphragm wall and piping lane top and bottom is the most firm, so never adopting in Shi Jian With using as the diaphram wall of foundation pit enclosure directly as the engineering precedent of piping lane sidewall.

Summary of the invention

First to be solved by this invention technical problem is that and provide one the suitableeest for above-mentioned prior art present situation Share the diaphram wall constituting piping lane sidewall in piping lane, this diaphram wall can be convenient in adjacent two undergrounds when construction Build the base plate of piping lane between diaphragm wall, ensure that the connection between diaphram wall and piping lane base plate is firm simultaneously.

The present invention solves the technical scheme that above-mentioned technical problem used: a kind of underground constituting piping lane sidewall is continuous Wall, including the body of wall being spliced to form by the many concrete-piles squeezed into successively in soil, it is characterised in that: adjacent two concrete It is provided with one section of first assemblage gap between the medium position of stake, in described first assemblage gap, is fixed with the first anchoring piece, first Anchoring piece stretches out the end face of body of wall.Concrete-pile can be cross section be the pile body of H type, it is also possible to be cross section be that rectangle includes Square and rectangular concrete-pile, or the pile body of other cross sectional shapes.The medium position of described concrete-pile, refers to position The a certain position of the pile body between two ends of pile body, does not means that the center position at 1/2nd of pile body, certainly, From the point of view of actual requirement of engineering, the first assemblage gap is typically situated at 1/2nd of pile body length between 1/4th A certain correct position.It is fixed with at the existence of the first assemblage gap, and the first assemblage gap and exposes outside the of body of wall end face One anchoring piece, thus convenient, firm back plate connections can be obtained at the medium position of diaphram wall, it is simple in adjacent two places The framework of steel reinforcement structure of piping lane base plate and inside thereof is built between the medium position of lower diaphragm wall.
