Description

A kind of underground engineering sluicing decompression float Structure

Technical field

The utility model belongs to drainage and anti-float field, and in particular to a kind of underground engineering sluicing decompression float Structure.

Background technique

In architectural design, basement, which is rationally arranged, can efficiently use the underground space, enrich the use function of building.I State reform and open up to the outside world since with construction market development, more and more architectural designs use that monomer area is big, buried depth is big Scheme form with basement.In the anti-floating for solving the problems, such as such basement, conventionally employed engineering way can be divided into three Major class processing mode, i.e. increase counterweight balance buoyancy force of underground water using backfilling material or dead load second is that anti-by setting Bar or uplift pile weigh anchor to prevent structure floating, solves the problems, such as anti-floating, third is that, i.e., two methods of front are used in combination.

With the quickening of urbanization process, available urban land resource is fewer and fewer, and the exploitation of the underground space is also increasingly One of Main way as urban development, Large Underground garage parking, underground commercial center, underground terminal engineering are more and more.By Various aspects factor influences, and this kind of construction of underground structure does not plan that upper cover property or upper load are smaller sometimes, so that underground structure Anti-floating problem is particularly pertinent.How not only economize on resources, the energy, but also on surrounding enviroment influence it is small under the premise of, it is anti-to solve structure Floating problem, is to greatly develop one of the major issue that the underground space must face.Currently, most of construction of underground structure is by increasing Add the measure of structure resistance to plucking or increases the methods of structure itself and upper load to solve the problems, such as anti-floating.

There are mainly five types of the design schemes that the country takes for such underground structure anti-floating, but all in place of Shortcomings, the First is that counterweight of backbreaking increases structural weight per square meter by suitably increasing buried depth to resist buoyancy.Increasing embedded depth of foundation will increase foundation pit and open Digging amount increases pattern foundation pit supporting structure depth, increases underground structure height and indoor backfill amount.The water that can be increased due to the weight of counterweight Head buoyancy offsets a part, therefore its efficiency is lower.Lesser engineering, i.e. anti-floating safety coefficient K f are differed with buoyancy suitable for self weight It is anti-float anchor rod close to 1.0 engineering, second, anti-floating is carried out using the withdrawal resistance that rock-bolt provides.Suitable for rock foundation Or the lesser engineering of substrate distance bedrock surface.And the problems such as that there are durabilities is bad, waterproof slab, using less the in engineering Third is that uplift pile, carries out anti-floating using the withdrawal resistance that uplift pile provides.Very suitable for non-rock foundation or substrate distance bedrock surface Big engineering.Since uplift pile is required to control by crack, cannot be given full play to the resistance to plucking frictional resistance of foundation soil, therefore its efficiency It is not high, and cost is higher, the duration longer fourth is that outdoor drainage system, using natural way or artificial mechanism dewatering mode by ground Water level control is lauched in certain elevation, so that the buoyancy of underground water is less than structural weight per square meter, meets the requirement of related specifications.It is main suitable For Slope Architectural, in the case where peripheral ring allows, cost is lower.But operation and maintenance are difficult, after the several years there may be Silting, influences dewatering effect, is finally indoor precipitation system, french drain and collector pipe network system is arranged under sole plate, by ground It is lauched and the discharge of pipe network in house system is introduced by collector pipe network, to achieve the purpose that control groundwater level.Suitable for anti-floating The engineering that design head is smaller and the increment of groundwater is little.Operation and maintenance are convenient, but occupy indoor use space, once pipe network Damage, replacement are difficult.

Utility model content

The purpose of this utility model is that solve the above-mentioned problems and provides a kind of underground engineering sluicing decompression anti-floating Structure.

The utility model achieves the above object through the following technical schemes:

A kind of underground engineering sluicing decompression float Structure, including sidewall of basement, bearing plate and sole plate, the basis The bearing plate is arranged in substrate, and overburden layer, the sidewall of basement outside and the base are provided with above the bearing plate It is provided with blind-ditch pipe below plinth bottom plate, water valve is provided on the blind-ditch pipe, the blind-ditch pipe is connected in sump, described Sump is connected to water pump by pipeline convenient for draining, and water level monitoring unit is provided in the sump for real-time monitoring water Position height, the water level monitoring unit communication are connected to control host, and the control host is connected with alarm unit convenient for issuing Alarm and reminding staff.

In order to further improve underground engineering sluicing decompression float Structure practicability, the blind-ditch pipe is filled using rubble Inside bury flexible porous tube.

In order to further improve underground engineering sluicing decompression float Structure practicability, the blind-ditch pipe arrangement is divided to two Point, basis is above along one circle row of building periphery setting under the sole plate and other than the external main structure of the sidewall of basement Water french drain constitutes annular drainage system.

In order to further improve underground engineering sluicing decompression float Structure practicability, the french drain on the blind-ditch pipe periphery is removed Rubble filling is outer to be additionally provided with loaded filter and waterproof layer.

Institute in order to further improve underground engineering sluicing decompression float Structure practicability, on the outside of the sidewall of basement It states and is additionally provided with water blocking layer inside overburden layer convenient for preventing rainwater from vertically permeating.

In order to further improve underground engineering sluicing decompression float Structure practicability, the control host, which is provided with, to be compared Device is sounded an alarm for comparing warning line and actual water level to control the alarm unit.

In above structure, incorporation engineering geology and ambient conditions are done under the sidewall of basement and the sole plate Sluice the blind-ditch pipe, and the blind-ditch pipe uses to be buried described in flexible porous tube in rubble filling.Water level monitoring unit is for monitoring The height of water level of the sump, which is simultaneously fed back, arrives the control host, by the blind-ditch pipe will penetrate into the sidewall of basement and Underground water under the sole plate collects in the sump, when water level is excessively high, then passes through the water pump and described blind Sewer pipe is drained into external tank, within the anti-floating ability of structure itself, to reach and " sluice hydrostatic water table control The purpose of decompression ", and then reduce anti-floating project amount.

Beneficial effect is: the utility model is different from the thinking of tradition " resisting water buoyancy ", logical on underground structure periphery The water drainage measure that setting permanently uses is crossed, by level of ground water control in scheduled elevation range, to reduce or eliminate ground It is lauched the buoyancy effect to building, and then reduces anti-floating project amount, saves social resources, generates huge society and economic effect Benefit.
